Help with pong like game
Hi all profesionals.
I am trying to create a pong like game, called PinPong (As it is a mix of pinball and pong)
However, i am not happy with how the ball behaves in the game.
Does anyone have some insigt on how to go about improving this behaviour?
Thanx!

First of all, thx for trying to help!
well.. its a different kind of snake game: the starting point of the snake always stays the same. this means, that the snake grows longer and longer, without the butt moving behind the snake, but staying in the same position.
so, if i'd try to put all those lines into an array (every line of the snake is very small, it is been added every 30 millisecs another line) this array would explode, and this would not be a very fast or elegant solution. so i think it must be possible to read the Color of a single pixel, the pixel, where the snake moves next... so that if the color would be other than the background color, it should stop, because the snake must have been crashed into something.
so.. i posted this into an earlier thread and somebody said the class BufferedImage and its method getRGB() should help. im currently trying to do so, but it doesnt work.
i cant seem to get the data from the JPanel (where i am drawing the snakes (i think thats the problem)) into the bufferedimage.. anyone could help, please?
here is some code from the game:
CODE
BufferedImage bi = new BufferedImage(505,505,BufferedImage.TYPE_INT_RGB);
CurrentBackgroundRGB = bi.getRGB((int)(Worm1.xStart+Worm1.x),(int)(Worm1.yStart+Worm1.y));
if(HintergrundRGB != BackgroundCol.getRGB())this.interrupt();
end CODE
"this" is the current thread of the animation
I think the problem is obvious: how can i get the Buffered image to check the data from my JPanel?

Plz help with snake-like game..
hi.
i am new to java and want to programm a kind of worm-game where there are multiple worms, each different color and when your worm (you can choose your direction by pressing left and right button) crashes in something, that isnt the clear background (worms or the border rectangle) then it should stop. so my problem is:
how can I get the program to know, that the worm has crashed into something?
i think the easiest solution would be, if I could determine the Color of a specific Pixel on the canvas (i am using a canvas for the playfield).
or another solution could be that if i could determine, wheter the Pixel is an element of the worm or the rectangle (dont think this is possible).
somebody wrote in an earlier question that i should use the buffered image class. im currently trying to do so.
another big problem is, that it has to be very fast. its a problem that i have to, in order to show the animation, repaint the canvas every 30 milisecs or so (im using a thread). is there a possibility to only redraw the worms? (im using g2d lines as "worms", that are beeing added every animation another line)

i'm making a game at the moment.......
i need help with a way to check all the hashmaps of enimies in a class called room......i need to check if they all == 0...when they all equal zero the game ends......
i know i can check the size of a hash map with size().....but i want to check if all the hashmaps within all the rooms == 0.First of all stop cross posting. These values in the HashMap, they are a "Collection" of values, so what is wrong with reply two and putting all these collections of values into a super collection? A collection of collections? You can have a HashMap of HashMaps. One HashMap that holds all your maps and then you can use a for loop to check if they are empty. A map is probably a bad choice for this operation as you don't need a key and an array will be much faster.
HashMap [] allMaps = {new HashMap(),new HashMap()}; -
Hi. My name's Rory.
I am an artist.
http://www.youtube.com/profile?user=PimpOfPixels
http://roaring23.cgsociety.org/gallery/
I am learning action script and Flash so that I can make
games.
I am not a complete novice in programming. I am proficient in
Java and in MaxScript (3DSMAX embedded language).
I have been making some progress in action script and I have
a functional (although incomplete) game in the works. You can view
it here:
http://secure2.streamhoster.com/~rlu...orniverous.swf
The idea is it's a color game
red beats green, green beats, blue beats red. Think paper
scissor rock.
The idea is to change the entire circle into one color.
The graphics are place holders BTW.
I am using FlexBuilder 2.0 and Flash CS3, and I have come
across a problem not covered in either of my books.
I'd really appreciate any help that you guys can offer.
I have gotten this far on my own.
My #1 question (and I have many more) is:
How do you through Flash specify animation segments for a
MovieClip Symbol?
Notice how the red creatures occasionally open their mouths.
I want to have a walk, an attack, an absorb, and a bounce animation
on the same timeline and trigger the appropriate one depending on
which color the creature collides with. I do not know how to go
about this problem. I’ve just been trying to get the walk
animation to loop without playing the attack animation so far.
I've tried frame-labeling in flash, with scripts on the key
frames of a second layer that specify when to stop or repeat the
animation... No dice.
I have a symbol named RedShot in the library of a flash
project named "graphics"
In my timeline I have 2 animation segments, and I have a
second layer denoting two corresponding frames named "walk" and
"attack" from the properties menu.
On the final frames of the animations I have scripts.
Code:
gotoAndPlay("walk");
and
Code:
gotoAndPlay("attack");
respectively.
Im my library I have linkage options specified as such:
Class:RedShot
BaseClass:flash.display.MovieClip
export of actionscript#CHECKED
export on 1st frame#CHECKED
on the main stage of my flash project I have actionscript for
2 functions:
Code:
function walk(){
red_shot.gotoAndPlay("walk");
function attack(){
red_shot.gotoAndPlay("attack");
I export the project and the opened window has the "walk"
animation looping properly.
In my FlexBuilder project I embed the symbol
Code:
//Inside class global variables:
[Embed(source="../graphics.swf", symbol="RedShot")]
public var RedShot:Class;
private var _shot:MovieClip;
Code:
//and in my buildShot function:
_shot = new RedShot();
addChild(_shot);
When I build the project the characters appear, and they
animate. The only trouble is that there are no breaks in the
animation. The animation loops right through the frames where I
have specified that the animation should "gotoAndPlay" from a
different part.
What's weirder is that I can call
Code:
"gotoAndPlay("attack");"
without an error and it will go to and play from that point.
The only trouble is that it will begin to loop the entire animation
again without stopping at the gotoAndPlay events stored in the
frames of the timeline.
It seems like all embedded actions are ignored, add I can't
think of another way to controll the animation.
Any thoughts?After hours of searching the internet I finally got this
blasted question figured out.
How to you export a symbol from Flash for use in a Flex
Builder project without destroying actionscript stored within the
frames of the Symbol's timeline?
That's a long winded way of saying: "In FlexBuilder, how do
you control MovieClips from Flash". I'm trying to make games, and
this was a particularly important question for me :).
Here's how:
1) You need a hotfix from Adobe.
[HTML]http://kb.adobe.com/selfservice/viewContent.do?externalId=kb401493&sliceId=2[/HTML]
This allows Flash CS3 to export a SWC file.
2)You have to set the linkage properties for your various
symbols in the flash library panel.
a)right click on symbol in library panel
b)choose "linkage"
c)"Class:" = (pick a name)
d)"Base class:" = flash.display.MovieClip;
e)"Export for ActionScript" = CHECKED
f)"Export in first frame"=CEHCKED
3)If you want to have multiple segmented animations as I
certainly did you'll want to create frames and actionscripts within
the symbols timeline to define where these animations are.
a) in the symbol's timeline make a second layer. We'll name
that layer "labels" for the sake of not having this get too
confusing.
b) on that layer create a new frame for each of the animation
segments that you'd like to define and stretch them to the length
of the corresponding animations.(I'm assuming that you have a
keyframe animation on the 1st layer... otherwise what's the point
of all this :P?)
c)in the properties panel name the frames in the "labels"
layer accordingly ie. "walk" "run" shoot" etc.
d)Define whether the various animations play once or loop by
adding a script to the last frame of the animation. If you want the
animation to loop add
[CODE]gotoAndPlay("name-of-the-animation");[/CODE]
if you want the animation to play once and stop add
[CODE]stop();[/CODE]
if you want the animation to play once and then return to a
different animation add
[CODE]gotoAndPlay("name-of-a-different-animation");[/CODE]
4) now you can export the symbols to an SWC file. Note: you
do not get this option unless you have installed the hotfix.
[HTML]http://kb.adobe.com/selfservice/viewContent.do?externalId=kb401493&sliceId=2[/HTML] .
a)rightclick on a symbol in the library panel
b)choose "exportSWCfile..."
c)export the file to a logical place such as the root of your
FlexBuilder project.
5) Now you have to tell flexbuilder about the new SWC file.
Note: Once this file is added to the FlexBuilder library you can
instantiate classes from it as though they were included using the
"include" function.
a)Right clicking on the root of the project in the Navigator
view.
b)going to properties.
c)Going to library path. (2nd tab)
d)and pressing the "Add SWC" button
Now you're done and you can instantiate any of the symbols
from your library while preserving any actions from your symbols
timeline just as though you had imported it as a class from a
typical library.
Sweet huh?
Thanks to the countless people and internet resources I found
on the subject. Hopefully it will be easier for anyone who finds
this post.
Here's an adobe video which covers the basic process.

}Kevin Bacon Game
For a description of the Kevin Bacon game, follow this link http://www.cs.virginia.edu/oracle/ . Try the game a few times and see if you can find someone with a Bacon Number higher than 3. In this program you will find all persons with a Bacon Number of 8 or higher. One of these persons is a former President of the United States.
Strategy
This is basically a shortest path problem. After that is done, find the large Bacon numbers by scanning the bacon numbers and print out the high-numbered actors and their chains. To print out a high-numbered actor, you should use recursion. Specifically, if some actor x has a Bacon number of b, then you know that they must have been in a movie with someone, call them actor y with a Bacon number of b-1. To print out x's chain, you would print out y's chain (recursively) and then the movie that x and y had in common.
The Input Files
There are two data files; both have identical formats. These files are: actors file and actresses file. These files are both compressed in .gz format, and were obtained from the Internet Movie Database. Combined, they are 52 Mbytes (compressed!) and were last updated October 17, 2002. These files are available at ftp://ftp.imdb.com/pub/interfaces/
These datafiles contain approximately 571,000 actors/actresses in a total of 192,000 movies, with 2,144,000 roles. These files also list TV roles, but you must not include TV roles in your analysis.
Before you run on the large data sets, use the small (uncompressed) file sample.list(http://www.fiu.edu/~lmore004/cop3530/sample.list) to debug the basic algorithms. In this data file, there are six actors, named a, b, c, d, e, and f, who have been in movies such as X, Y, and Z.
Input File Hints
Since it is not my input file, I cannot answer questions about it. Here are some observations that I used in my program, that should suffice. You can read the input file line by line by wrapping a FileInputStream inside a BufferedInputStream inside a GZIPInputStream inside an InputStreamReader inside a BufferedReader. You may not uncompress the file outside of your program.
There are over 200 lines of preamble that can be skipped. This varies from file to file. However, you can figure it out by skipping all lines until the first occurrence of a line that begins with "Name", and then skipping one more.
There are many postamble lines, too, starting with a line that has at least nine dashes (i.e. ---------).
A name is listed once; all roles are together; the name starts in the first column.
A movie title follows the optional name and a few tab stops ('\t'). There are some messed up entries that have spaces in addition to tab stops.
The year should be part of the movie title.
Movies made in 2003 or later should be skipped.
A TV movie, indicated by (TV) following the year, is to be skipped.
Archive material, indicated by (archive footage), is to be skipped. (Otherwise JFK is a movie star).
Cameo appearances, indicated by [Cameo appearance], should be skipped.
A TV series, indicated by a leading " in the title is to be skipped.
A video-only movie, indicated by (V) following the year is allowed.
Blank lines separate actors/actresses, and should be skipped.
Strategy
In order to compute your answers, you will need to store the data that you read. The main data structures are a Map in which each key is an Actor and each value is the corresponding list of movies that the actor has been in, and then a second Map, in which key is a movie and each value is the list of Actors in the movie (i.e. the cast). A movie is represented simply as a String that includes the year in which it was made, but an Actor includes both the name of the actor, and a data field that you can use to store computed information later on. Thus, ideally, you would like to define a class that looks somewhat like this (with routines to compute Bacon Numbers not listed):
public class Database
private static final class Actor
String name;
int data; // Bacon number ,
// determined by computeBaconNumbers
public String toString( )
{ return name; }
public int hashCode( )
{ return name.hashCode( ); }
public boolean equals( Object other )
{ return (other instanceof Actor) &&
( (Actor) other ).name.equals( name ); }
// Open fileName; update the maps
public void loadFile( String fileName ) throws IOException
public int getActorCount( )
public int getMovieCount( )
private Map actorsToMovies = new HashMap( );
private Map moviesToActors = new HashMap( );
Memory Details
The description above is pretty much what you have to do, except that you must take extra steps to avoid running out of memory.
First, you will need to increase the maximum size of the Java Virtual Machine from the default of 64Meg to 224Meg. You may not increase it any higher than that. If you are running the java interpreter from the command line, the magic option is -Xmx224m. If you are using an IDE, you will have to consult their documentation --- don't ask me.
Second, you will quickly run out of memory, because if you find two movies that are the same, but are on different input lines, the default setup will create two separate (yet equal) String objects and place them in the value lists of two different actors. Since there are 2.1 million roles, but only 192,000 movies, this means that you will have ten times as many String objects as you really need. What you need to do is to make sure that each movie title is represented by a single String object, and that the maps simply store references to that single String object. There are two basic alternatives:
The String class has a method call intern. If you invoke it, the return value on equal Strings will always reference the same internal String object.
You can keep a HashMap in which each key is a movie title, and each value is the same as the key. When you need a movie title, you use the value in the HashMap.
Option two is superior (performancewise) to option #1 and it is required that you use it to avoid memory problems.
When you maintain the list of movies for each actor, you will want to use an ArrayList. It takes little effort to ensure that the capacity in the ArrayList is not more than is needed, and you should do so, to avoid wasting space (since there are 571,000 such array lists).
When you construct the HashMaps, you can issue a parameter (the load factor). The higher the load factor, the less space you use (at the expense of a small increase in time). You should play around with that too; the default is 0.75; you will probably want a load factor of 2.00 or 3.00.
You must be very careful to avoid doing any more work in the inner loops than you need to, including creating excessive objects. IF YOU CREATE EXCESSIVE OBJECTS, YOUR PROGRAM MAY SLOW TO A CRAWL BECAUSE ALL ITS TIME WILL BE SPENT IN THE GARBAGE COLLECTOR OR RUN OUT OF MEMORY COMPLETELY.
What to Submit
Submit complete source code and the actors/actresses with Bacon Numbers of 8 or higher. Include the complete paths for each of the actors/actresses (with shared movie titles). Also indicate how long your algorithm takes. This means how long it takes to load, and also how long it takes to run the shortest path computation (not including the output of the answer), by inserting calls to System.currentTimeMillis at appropriate points in your code, and tell me how many actors and movies there are. Also, insert this code (at the end of your program) that tells me how large the VM is:
Runtime rt = Runtime.getRuntime( );
int vmsize = (int) rt.totalMemory( );
System.out.println( "Virtual machine size: " + vmsize );
Don't forget to write in the processor speed of the computer you are using. If it's somewhat fast, or provably space-efficient, you can get extra credit. You cannot receive credit for a working program if your program fails to produce a large set of actors and actresses with Bacon Numbers of 8 or higher. Note: the data you will work on and the data the Oracle uses (and the IMDB data) are all slightly out of sync. So you might not be able to exactly reproduce the results, although I was able to get a complete set of Bacon Numbers 8 and higher when I ran my program on October 23, using the Oct 17 files.
Due Date
This program is due on Thursday November 14.
Additional Notes
The exact sizes of the data files are 36381624 and 18263563 bytes, respectively. If you download and the files are larger, then you messed up the download. Note that if you are using Windows XP, these files might be uncompressed during downloading. If so, you can use this program to recompress the file. If the files are smaller, then the download probably got interrupted before it finished and you will need to retry. Here is a gzipped sample.list for you to test that aspect of your program.
Running on COTTON in the AUL, which is a 450 MHz Pentium III, and accessing the files over the network as "\\\\couger\\cop3530\\actors.list.gz", (and similarly for actresses.list.gz), and with no other processes running besides notepad, the data files loaded in 180 seconds. You should be able to get faster results on a faster machine. Some of the AUL machines are 1.6 GHz. You should indicate which AUL machine (with processor speed) ran your submission.
Entries with years such as (1996/I) are optional.
When writing and reading make sure you are using BufferedInputStream and BufferedOutputStream, as appropriate.

I need some help with my java game using applets, CAN SOMEBODY PLEASE HELP
Hi,
I am in the process of creating a RPG program using Java. I am not very experienced with java, however the problem i am currently facing is something i can't seem to figure out. I would like to draw a simple grid where a character (indicated by a filled circle) moves around this grid collecting items (indicated by a red rectangle). When the character moves on top of the grid with the item, i would like it to disappear. Right now i am not worrying about the fact that the item will reappear after the character moves away again, because sometimes, when the character moves over the item, nothing happens/another item disappears. i have been at this for 4 days and still cannot figure out what is goign on. can somebody please help me? it would be most appreciated.
Thanks
PS if i needed to send you my code, how do i do it?Thank you for replying.
The thing is, I am taking java as a course, and it is necessary for me to start off this way (this is for my summative evaluation). i agree with you on the fact, however, that i should go in small steps. i have been doing that until this point, and my frustration caused me to jump around randomly for an answer. I also think that it may just be a bug, but i have no clue as to how to fix it, as i need to show my teacher at least a part of what i was doing by sometime next week. Here is my code for anybody willing to go through it:

Need help with " Number guessing game " please?
This is what teacher requires us to do for this assignment:
Write a program that plays a simple number guessing game. In this game the user will think of a number and the program will do the guessing. After each guess from the program, the user will either indicate that the guess is correct (by typing �c�), or that the next guess should be higher (by typing �h�), or that it should be lower (by typing �l�). Here is a sample output for a game. In this particular game the user thinks of the number 30:
$java GuessingGameProgram
Guess a number between 0 and 100
Is it 50? (h/l/c): l
Is it 25? (h/l/c): h
Is it 37? (h/l/c): l
Is it 31? (h/l/c): l
Is it 28? (h/l/c): h
Is it 29? (h/l/c): h
Is it 30? (h/l/c): c
Thank you for playing.
$
This program is implementing a binary search algorithm, dividing the range of possible values in half with each guess. You can implement any algorithm that you want, but, all things being equal, binary search is the best algorithm.
Write the program so that the functionality is split between two classes: GuessingGameProgram, and NumberGuesser.
GuessingGameProgram will only be used for its main function. It should instantiate a NumberGuesser, and it will be responsible for the loop that notifies the user of the next guess, reads the �h�, �l�, or �c� from the user, and sends an appropriate message to the number guesser accordingly.
The guesses themselves should all be generated by the NumberGuesser class. Here is a diagram of the members and methods for the class. Notice that the members are unspecified. Feel free to give your NumberGuesser class any members (which we have also been calling fields, or instance variables) that you find useful. Make them all private.
NumberGuesser
NumberGuesser(int upperLimit, int lowerLimit)
int guess()
void higher()
void lower()
The constructor should take two integer arguments, a lower and upper bound for the guesses. In your program the constructor will be called with bounds of 0 and 100.
The guess method should return the same value if it is called more than once without intervening calls to the lower or higher methods. The class should only change its guess when it receives a message indicating that its next guess should be higher or lower.
Enjoy. Focus your attention on the NumberGuesser class. It is more interesting than the GuessingGameProgram class because it is a general-purpose class, potentially useful to anybody who is writing a number guessing game. Imagine, for instance, that a few weeks from now you are asked to write a number guessing game with a graphical Java Applet front end. If you NumberGuesser class is well written, you may be able to reuse it without any modifications.
I'm new to JAVA and I'm set with my 2nd homework where I'm so confused. I know how to do something of this source in C language, but I'm a bit confused with Java. This is the code me and my classmate worked on, I know it's not 100% of what teacher asked, but is there any way possibly you guys could help me? I wrote this program if the game is played less then 10 times, thought I would then re-create a program without it, but now I'm confused, and my class book has nothing about this :( and I'm so confused and lost, can you please help? And out teacher told us that it's due the end of this week :( wish I knew what to do. Thank you so so much.
Here's the code:
import java.text.*;
import java.io.*;
class GuessingGame
public static void main( String[] args ) throws IOException
BufferedReader stdin = new BufferedReader(new InputStreamReader( System.in ) );
int guess = 0, limit = 9, x = 0, n, a = 0 ;
double val = 0 ;
String inputData;
for ( x = 1; x <= 10; x++) //number of games played
System.out.println("round " + x + ":");
System.out.println(" ");
System.out.println("I am thinking of a number from 1 to 10. ");
System.out.println("You must guess what it is in three tries. ");
System.out.println("Enter a guess: ");
inputData = stdin.readLine();
guess = Integer.parseInt( inputData );
val = Math.random() * 10 % limit + 1; //max limit is set to 9
NumberFormat nf = NumberFormat.getNumberInstance();
nf.setMaximumFractionDigits(0); //format number of decimal places
String s = nf.format(val);
val = Integer.parseInt( s );
for ( n = 1; n <= 3; n++ ) //number of guess's made
if ( guess == val)
System.out.println("RIGHT!!"); //if guess is right
a = a + 1;
System.out.println("You have won " + a + " out of " + x + " rounds");
System.out.println(" ");
n = 3;
continue;
if (n == 3 && guess != val) //3 guesses and guess is wromg
System.out.println("wrong");
System.out.println("The correct number was " + val);
System.out.println("You have won " + a + " out of " + x + " rounds");
System.out.println(" ");
continue;
//how close guess is to value
if ( guess == val - 1 || val + 1 == guess) //Within 1
System.out.println("hot");
else if ( guess == val - 2 || val + 2 == guess) // Within 2
System.out.println("warm");
else
System.out.println("cold"); // Greater than 3
inputData = stdin.readLine();
guess = Integer.parseInt( inputData );
//ratings
if ( a <= 7)
System.out.println("Your rating is: imbecile.");
else if ( a <= 8)
System.out.println("Your rating is: getting better but, dumb.");
else if (a <= 9)
System.out.println("Your rating is: high school grad.");
else if ( a == 10)
System.out.println("Your rating is: College Grad.!!!");Try this.
By saying that, I expect you ,and your classmate(s), to study this example and then write your own. Hand it in as-is and you'll be rumbled as a homework-cheat in about 20ms ;)
When you have an attempt where you can explain, without refering to notes, every single line, you've cracked it.
Also (hint) comment your version well so your tutor is left with the impression you know what you're doing.
In addition (huge hint) do not leave the static inner class 'NumberGuesser' where it is. Read your course notes and find out where distinct classes should go.
BTW - Ever wonder if course tutors scan this forum for students looking for help and/or cheating?
It's a double edged sword for you newbies. If you ask a sensible, well researched question, get helpful answers and apply them to your coursework, IMHO you should get credit for doing that.
On the other hand, if you simply post your assignment and sit there hoping some sucker like me will do it for you, you should be taken aside and given a good kicking - or whatever modern educational establishments consider appropriate abmonishment ;)
I'd say this posting is, currently, slap bang between the two extreemes, so impress us. Post your solution in the form you intend to hand it in, and have us comment on it.
Good luck!

I need help with an app game purchase
I recently added 20$ to my account with 2 10$ Itunes cards. I play the app called clash of clans, in the game you can buy things with itunes, I tried to make a purchase for 19.99 when there is just about 21 $ in my itunes and it's telling me I have insufficient funds. This is odd becusee a couple days ago I did the same thing with the itunes card but now I'm getting this error. I checked my itunes again and I have the money, please help!
What country are you in ? If you are in the US then does your state's sales tax take it over what you have on your account ?

SO I've just begun to make a text based game and i've already ran into a problem :/
I've made a switch statement that has cases for each of the classes in the game..for example
Output will ask what you want to be
1. Fighter
2. etc
3. etc
case 1: //Fighter
My problem is i want to be able to display the class
as in game class not java class
as Fighter
That may be a bit confusing to understand sorry if it isn't clear

Need help with a guessing game
Hi. hopefully, this is a really easy issue to resolve. I had to write a program that administers a guessing game, where the computer chooses a random number, and the user has to guess the number. If the user doesn't get it within 5 guesses, they lose and start all over with a new number. I have this all in a while loop (as per my instructions). My issue is that whenever the user enters 0, the program should quit with the users final score and so on. My program will not quit unless the 0 is entered on the last (fifth) guess. please help, it would be very appreciated. Here is my code:
import java.util.Scanner;
public class guessgame {
public static void main(String[] args) {
Scanner scanner = new Scanner (System.in);
int randnum; //random number generated by computer
int userguess = 1; //number the user guesses
int userscore = 0; //number of correct guesses by user
int compscore = 0; //number of times not guessed
int guessnum = 0; //number of guesses for one number
int gamenum = 0; //number of games played
System.out.println ("I will choose a number between 1 and 10");
System.out.println ("Try to find the number using as few guesses as possible");
System.out.println ("After each guess i will tell you if you are high or low");
System.out.println ("Guess a number (or 0 to quit)");
while (userguess != 0) {
randnum = 1 + (int)(Math.random() * 10); //generates random number
gamenum ++;
userguess = userguess;
for (guessnum = 1; guessnum < 6 && userguess != randnum; guessnum ++) {
userguess = scanner.nextInt();
userguess = userguess;
if (guessnum >= 5) {
System.out.println ("You did not guess my number!");
} //closes if statement
if (userguess == randnum) {
userscore ++;
System.out.println ("You guessed it! It took you " + guessnum + " tries.");
System.out.println ("If you want to play again, enter a guess");
System.out.println ("If you do not want to play again, enter 0");
} //closes if statement
else if (userguess < randnum)
System.out.println ("Your guess is too low");
else if (userguess > randnum)
System.out.println ("Your guess is too high");
}//closes for loop
} //closes while loop
compscore = gamenum - userscore;
System.out.println ("Thanks for playing! You played " + gamenum + " games");
System.out.println ("Out of those " + gamenum + " games, you won " + userscore + " times");
System.out.println ("That means that I won " + compscore + " times");
} //closes main
} //ends guessgame classThe problem with your program is that the while loop doesn't get checked. The condition of the while loop will only get checked each iteration, and not during one iteration. The time you are in your for-loop is still one iteration so it won't check if userguess is 0. see it liek this
While: is userguess 0, no, do 1 iteration
while-iteration-forloop: check 5 guesses, userguess can be anything even 0 while loop won't stop.
end of for loop
end of while-iteration
new while iteration, is userguess 0?
and so on.

Help with saving FarmVille game data...
Ok, I need a bit of help...
I have an issue with saving data from a facebook game, FarmVille.
On my old computer which was running Windows XP when playing FarmVille the game only ever used to reload when it was updated. If I quit the game then went back in and it appeared to be loading the content from some saved data as it would load straight away compared with the 5 minutes it took when ever the game was updated.
I have now bought a new computer running Windows 7 and when I play FarmVille it now wants to reload from scratch each time I go into the game and it is sucking up my broadband usage really quick by doing this.
I have been trying to play around with different settings to see if I can get flash player to save the data but nothing seems to work. I am now starting to think it may not be flash player that is the problem.
If anyone knows how to fix this problem it would be greatly appreciated.
Thanks.I am using IE9 but I do not have that setting set and I hardly ever delete all my history etc.
I have also just tried playing on my partners apple which I dont know much about except that it is about 5 years old. Anyway the apple is doing the same thing that this new computer is doing... hmmm. -
Need a little help with a trivia game
Hey guys I was wondering if I could get some help. I'm taking a class at school for java programming and its my first class. And I have to do a final assignment, which is to make a java trivia game. I have all the parts coded already pretty sure. Now be forewarned that I'm not "that" great at programming.
But the part that I'm stuck on and cant really get any help on is this: For the game I need to have a file with all the questions and answers, which is created already and works. The file writer has the question, choice 1, choice 2, choice 3, choice 4 and the answer written to it, in that order. We needed to implement a GUI and I coded that as a message label on top where the question will go, in the middle 4 radio buttons where the choices to the answer will go and on the bottom a next question, ok and quit button.
My question is this: How do I pull the information from the file that was written to appear in the GUI, such as the question and the choices for the answers for the question? ANY and ALL help would be appreciatedRead the information using a BufferedReader wrapped around a FileReader. Change your GUI using setText on the component you want to display the text.
Edit: An example that does both things
import java.io.*;
import javax.swing.*;
public class FileAndSwing {
public static void main(String[] args) throws Exception {
BufferedReader reader = new BufferedReader(
new FileReader("FileAndSwing.java"));
StringBuilder builder = new StringBuilder();
for ( String line = null; (line = reader.readLine()) != null; ) {
builder.append(line).append("\n");
JFrame frame = new JFrame("FileAndSwing.java");
frame.setSize(500, 500);
JTextArea field = new JTextArea();
frame.add(field);
field.setText(builder.toString());
frame.setVisible(true);
}This is also kind of a Quine :-).

Need help with Connect 4 game, IndexOutOfRangeException was unhandled
Hi! I've been struggling with this for a while now, the issue is that as soon i move a game piece to the field i get this errorats "IndexOutOfRangeException was unhandled" and i don't know why since my intention with the code was to use for loops
look through the 2D array thats based on two constants: BOARDSIZEx = 9 and BOARDSIZEy = 6. Instead of traditional 7*6 connect 4 grid i made it 9 squares wide due to having pieces on the side to drag and drop.
Here's the code for my checkwin:
public bool checkWin(Piece[,] pieceArray, bool movebool)
bool found = false;
//Horizontal
for (int i = 0; i < BOARDSIZEx - 3; i++)
for (int j = 0; j < BOARDSIZEy; j++)
if ((pieceArray[i, j] != null)
&& (pieceArray[i, j] == pieceArray[i, j + 1])
&& (pieceArray[i, j] == pieceArray[i, j + 2])
&& (pieceArray[i, j] == pieceArray[i, j + 3]))
if (pieceArray[i, j].IsStarter != movebool)
found = true;
goto Done; //interesting way of getting out of nested for loop
//for more on goto: http://stackoverflow.com/questions/324831/breaking-out-of-a-nested-loop
//Vertikal
for (int i = 0; i < BOARDSIZEx; i++)
for (int j = 0; j < BOARDSIZEy - 3; j++)
if ((pieceArray[i, j] != null)
&& (pieceArray[i, j] == pieceArray[i + 1, j]) && (pieceArray[i, j] == pieceArray[i + 2, j])
&& (pieceArray[i, j] == pieceArray[i + 3, j]))
if (pieceArray[i, j].IsStarter != movebool)
found = true;
goto Done; //interesting way of getting out of nested for loop
//for more on goto: http://stackoverflow.com/questions/324831/breaking-out-of-a-nested-loop
//Diagonal, Lower left to upper right
for (int i = 0; i < BOARDSIZEx - 3; i++)
for (int j = 0; j < BOARDSIZEy - 3; j++)
if ((pieceArray[i, j] != null)
&& (pieceArray[i, j] == pieceArray[i + 1, j +1])
&& (pieceArray[i, j] == pieceArray[i + 2, j + 2])
&& (pieceArray[i, j] == pieceArray[i + 3, j + 3]))
if (pieceArray[i, j].IsStarter != movebool)
found = true;
goto Done; //interesting way of getting out of nested for loop
//for more on goto: http://stackoverflow.com/questions/324831/breaking-out-of-a-nested-loop
//Diagonal, upper left to lower right
for (int i = 0; i >= BOARDSIZEx; i--)
for (int j = 0; j < BOARDSIZEy - 3; j++)
if ((pieceArray[i, j] != null)
&& (pieceArray[i, j] == pieceArray[i - 1, j + 1])
&& (pieceArray[i, j] == pieceArray[i - 2, j + 2])

found = true;
goto Done; //interesting way of getting out of nested for loop
//for more on goto: http://stackoverflow.com/questions/324831/breaking-out-of-a-nested-loop
Done:
return !found;
It's at the vertical check that the error occurs and also my checkwin doesnt seem to respond to the call in the game.cs code.
//check for win
bool moveBool = true; //returns yes or no depending on whether both players have moved their pieces
if (move % 2 == 0) moveBool = false;
bool win = rules.checkWin(pieceArray, moveBool);
//The game is won!
if (win)
string winningPlayerName = player1.Name; //creating a new player instance, just for shortening the code below
if (moveBool == false) winningPlayerName = player2.Name; //if it was player 2 who won, the name changes
message = winningPlayerName + " has won the game!\n\n"; //The name of the player
Board.PrintMove(message); //Print the message
if (moveBool == true) player1.Score += 1; else player2.Score += 1; //update score for the players
//The player's labels get their update texts (score)
Board.UpdateLabels(player1, player2);
//Here, depending on what one wants to do, the board is reset etc.
else
move++; //draw is updated
And here's a picture on how it looks like at the moment.
Thanks in Advance!
Student at the University of Borås, Swedenfor (int i = 0; i < BOARDSIZEx; i++) // If BOARDSizex is the number of elements in the first dimension...
for (int j = 0; j < BOARDSIZEy - 3; j++)
if ((pieceArray[i, j] != null)
&& (pieceArray[i, j] == pieceArray[i + 1, j]) && (pieceArray[i, j] == pieceArray[i + 2, j])
&& (pieceArray[i, j] == pieceArray[i + 3, j])) // Then [i + anything, j] will be out of range.
You probably meant to add the one, two, or three to the j rather than the i. -
Help with completing sentences game code
Hi, I`m a bit stuck, I`m making a game where you have to complete the sentences by dragging the words which are generated dinamically to its right place over some boxes, everything works fine but if you pull the words out of the boxes one all are placed it crashes.
Unfortunately this is someone elses code (another programmer who bailed on us in the middle of the proyect) although I manage to make it work with new words, making the draggable items undraggable one you place all 4 of them in the right boxes is totally unclear to me. I`ll appreciate any help I can get.
Here`s all the code that this part of the movie is using:
function aleatorio(min, max)
var _loc2 = true;
if (usados.length <= max - min)
while (_loc2 != false)
var _loc1 = Math.floor(Math.random() * (max - min + 1));
_loc2 = repetido(_loc1);
} // end while
usados.push(_loc1);
return (_loc1);
else
return (0);
} // end else if
} // End of the function
function repetido(num)
var _loc1 = false;
for (i = 0; i < usados.length; i++)
if (num == usados[i])
_loc1 = true;
} // end if
} // end of for
return (_loc1);
} // End of the function
