Java Game and bounds problem

Hey all,
I created four different backgrounds for a project I am creating. (The background are a top down view of a road with sidewalks). I have them named as road1, road2, road3, and road4.
I have two questions. My first and most important is if I have a little box I want to move around the screen (a character), how do I set bounds so it can't go past a certain point (i.e. the road is the only place it is allowed to go)???
And secondly, I know how to remove panels but if I wanted this to be a long road and once the character reaches the right side of the screen it would remove road1 and replace it with road 2. How would I accomplish this?? And once that is figured out, road 3 would replace road 2, but road 3 goes vertical so the character would go right through road 1 and right through road 2, but vertical through road 3 to get to road 4.
I have a bunch of code if anyone would like to see to help make sense of this, just let me know exactly what you would like to see.
Thanks in advance for all the help and I hope I didn't confuse anyone too much.
P.S. If this has already been discussed, I apologize. I looked, but couldn't find anything.

I created four different backgrounds for a project I

if I have a little box I want to move around the
screen (a character), how do I set bounds so it can't
go past a certain point (i.e. the road is the only
place it is allowed to go)???You have a couple of options that I know of--
1 - simple boundary check, your road needs to be straight or mathematically defined so you can check by position.
2 - easier: since you have sidewalks, you have a natural boundary--before you move check to see if the color of pixel is road or sidewalk. if road, then move to it, if sidewalk then do something else.
And secondly, I know how to remove panels but if I
wanted this to be a long road and once the character
reaches the right side of the screen it would remove
road1 and replace it with road 2. How would I
accomplish this?? And once that is figured out, road
3 would replace road 2, but road 3 goes vertical so
the character would go right through road 1 and right
through road 2, but vertical through road 3 to get to
road 4.You have to figure out what type of overlap point you want in each pannel: when you come off of 1 and go to 2 do you want to start on the extream edge or part way through? Once this is done you just need to make a simple adjustment to your location and repaint onto the new panel. Same for when you go to the left side. keep track of what road you are on and implement a conversion from 1 to 2, 2 to 3, 3 to 4, 4 to 1, 3 to 2, and 2 to 1.

you hit 1

you hit 1

RockCrab hit 7
your health is 24
you hit 1
RockCrabs health is 6
RockCrab hit 7
your health is 17
my point is whatever some one hits it always repeats that
my expected output would have to be something like
you hit 1
RockCrabs health is 9
RockCrab hit 9
your health is 37
you hit 3
RockCrabs health is 6
RockCrab hit 4
your health is 33

G4 Ti4600 VT2D8X - Locked games and other Problems

HELP!
I have been having problems with games locking up.
I looked at the MSI info in display properties and the card was checked at 4x, even though my bios setting of AGP compatability 3.0 is listed as 8X. It wouldn't let me check the 8X box.
So I downloaded the latest generic Nvidia driver (ver 44.03), and unfortunately, this cuased more problems.
Now I can't view the MSI info or MSI clock in display properties. I keep getting an XP error that says, "Run a DLL as an App has encountered a problem and needs to close"
Now mo matter how many times I uninstall the xp drivers and put the old one back in, I keep getting this error message trying to view MSI info in display properties.
When my games lock, threre isn't any sound loops happening, but the game freezes visually. I don't think I have a sound card conflict but here are my resources for you to take a look.
(ISA) 0 System Timer
(ISA) 1 Standard Keyboard

Also for the fun of it, I used Live update, only to notice that it detected a new driver for me to download for the Ti4800 card. Why does it not recognize my card?
Someone please help.

Richard and gfilitti,
Thank you very much for your continued help. This really means a lot to me.
Richard I do not use an antivirus program or a firewall program in the background for that matter.
The only other thing in my sys tray besides nview is a creative console. could that be locking things up?
gfilitti,
I acutally dsabled that firewire right after I listed my irq's to test that out. It's still disabled and doesn't seem to help the problem.
Is it a necessity that I disable system restore before using drivercleaner? If so I will do it, but would like to think the program would work as normal without doing that. Also not exactly certain where to disable the system restore.
So by having 10-second lock up issues, is it safe to say that I don't have any hardware conflicts or potential ram conflicts? There are no irq's being shared and I don't want to pull memory chips if you already know that's not the problem. I think I am getting close to ending this nightmare. Please help.
Thank you!!!!!!!!

Screeching sounds in games and other problems with Soundblaster live extern

Okay i have the USB external Creative soundblaster li've sound card. i have had a few problems. My first problem is When im in games such as Americas Army i get random Screeches like a tin can being scraped on concrete. My 2nd problem is Talking with my mic. For others to hear me MONITORING has to be enabled, there for i hear myself out of my own speakers as well. I have done everything to try and fix this, i've tried updating drivers, rolling back drivers, using windows automatic drivers. Is there an option i dont see that is causing my card to not sound good? I am using a 2.0 speaker configuration, and i only play the games with headphones on.
please help.
thanks for your time.Message Edited by Zombeh on 0-6-2006 08:30 AM

You waited 24 hours and gave up? So I'll offer this for anybody else who reads the thread. I have a USB external SB card, but it's in a box somewhere. But IIRC, the Volume Controls work similar to other SB cards. In Volume Controls, Playback, mute the Microphone. In Volume Controls, Recording, select Microphone. This should let you "record" without hearing it on your speakers. Now if a game sets the mixer options for itself, that complicates things. If allowed, choose game audio options similar to these Volume Controls.

New to this iPOD game, and having problems! Please help!

So I finally got my hands on a Nano yesterday, and ever since then some odd things have been happening. I would appreciate any help to the following questions/problems I've been having, because the applecare stuff does not seem to really be either helping or addressing my issues.
1. When starting iTunes, I was told (once it reconized my nano) that I neeed to install the new software for the nano, i expected this and downloaded it, and followed the directions. As soon as I did that though I started getting "Corrupted Error" messages in iTunes. To get this to stop I just reinstalled iTunes...I was able to transfer things now, but now the system does not seem to reconize that the nano has the new software, and asks if I want to install it, and when I do...(again) I start getting those corrupt errors again.
2. I will move some songs from my iTunes library, to my nano, and it says they transfer over. I then eject my nano from iTunes, wait for the "do not disconnect" to go away, and unplug it, and sometimes, my newly transfered songs are no longer on my nano. Am I doing something wrong?
3. I went to update my iPod with some playlists from my library, I went to the options, and said "only update from these lists" It updated my ipod...and deleted everything else off of it, and to add insult to injury, it only added the title of the play list, and NOT the actual song files
I know this is a lot, but I'm really frustrated, so any help would be appreciated.
Thank you so much for your time.

Hi,
Read this link if it happens again: iPod: What to do if Windows displays an "itunes.exe - Corrupt File" message
There is another post I think it is in the User Tips Library that goes into more detail as well.

Pogo games and Dashboard problems?

Hi everyone. I am having a problem ever since downloading Mountain Lion. While playing Crossword Cove on Pogo I will switch to Dashboard dictionary and enter a word for it's definition, when I finally decide what the answer could be I am not able to type into the crossword box. What am I doing wrong and how can I fix this? Any help would be appreciated. Thanks.

Try looking up your words using Spotlight and see if that works any better. It shows you the files with those words, but also runs them against the built-in dictionary.
Make sure you click in the entry box to get an insertion-point before you start typing. The first click just makes that window active -- the second click should give you the insertion-point.

Firmware update on my Nokia E52 only run java game...

Hi, I made that day Firmware update on my Nokia E52 and then update-s all right, only run java games and their sound is gone whether he shall be ON. Anybody have a similar problem and a solution for it?? Firmware-v 052.003 but the date is Cot. 29, 2010) will be happy if you give me an idea how to fix it! I tried quite moratoria preinstall, reset backup I have not done, unfortunately the old Firmware.

Okay, you are using a MacBook so I am not sure how much help I can give since I use a PC with Vista. In the latest version of Ovi Suite, once the update file has been downloaded and the installation starts, the computer will give your prompts that the phone is disconnected via USB, the phone restarts, the screen flashes, etc. I just leave it alone and after the progress bar on the Ovi Suite ends my phone is updated. I currently have v40. The free maps is available only to v31 and above for 5800 if I remember correctly.
If possible please use the Ovi Suite instead of PC suite (at least in my experience it works better), and do not in any way touch your phone during updates, even if it "disconnects" from the computer.
However regarding to your query as to why it is not available via the *#0000# method (or FOTA), updates are generally released through NSU before FOTA, sometimes with as much as a month in difference because the files in FOTA are not the entire update file but rather extractions from it. For example, the v40 FOTA is 17mb (according to someone who said he had it already), while the v40 I downloaded through Ovi Suite was 128mb.

Rank in a java game

Hi ppl,
I'm newbie in this forum, I'm development a java game and now I would like to implements a rank for players.
Basically, I have some players that play to the game and then (at game finish) game will write a .txt file with date, score and name player.
How I can implements it?
Thanks, regards.
Michael.

then need help in how implements...such as write in a txt file and then apply a bubble sort algorithm?What? You are thinking about it all wrong. Why would you write to a file and then sort?
One thing at a time. Split your problem up into smaller pieces. Sorting your data is a completely different issue than writing to a file, and for that I'd recommend googling comparators and looking up the sort functions of the Collections and Arrays classes in the API (since links don't work for you, go ahead and google those too).

The ever so savvy "creating a java game" post

Hey, I'm creating a java game, and I did research, and found that this question has been asked many, many times. But my question unfortunately did not match up with any of these posts :( So here goes...
Im creating a java game, which will run as....kind of a mix between a 2d game, and 3d game (no i am not insane). I dont want the original zelda look, and i dont want the first person shooter look, I want my character to be viewed from an angle, like tibia - if anyone has ever played that. And I also want to leave open the door to changing the view within the game. I figured I can just get my graphics friends to draw things in 3-d, (draw a house [draw the 4 sides and the roof]), and then somehow skew these images to accomodate for a different view.
I am more than willing to code some kind of graphics engine if what I need is not available, I have looked at a couple and found no such luck.
So what is the most efficient way to create this game? By just sortof getting all the graphics to be from a certain percpective, and then somehow modifying them with java.....
or by using some kind of graphics engine that allows me to change views? If so any recomendations?
Thanks a lot - wow this was long, oh yea a couple Dukes for this too thanks again
-Mark

you don't need to do any skewing. Here's what I'd do. I'd store all the tile information in a matrix (Object[][]) with a custom tile class that has the information it needs to retrieve its appropriate image, and certain game related data like slow down factor when a person walks over a certain type of tile, and whether it can be collided with. I'd draw them based on however you decide to angle your tiles. But the important part is you go in this order:
[0, 0], [0, 1], [1, 0], [0, 2], [1, 1], [2, 0], etc., etc....
The idea is if you're turning the floor 45 degrees clockwise, to give the correct illusion of depth, you'll want to draw the furthest back tile first, and the furthest tile forward last. Whether you start on the left or right depends on what angle you decide to work with. At a 45 degree angle, it obviously doesn't matter whether you start on the left or right. But if you guess wrong with your rendering, it will show because tiles that are closer to the "camera" will be overlapped by tiles further from the "camera".
for (int i = 0; i < tiles.length; i++) {
for (int j = 0; j < tiles.length; j++) {
graphics2D.drawImage(tiles[i].getImage(), i*horizontalSpacing - camera.getX(), j*verticalSpacing, camera.getY(), null);
}horizontalSpacing and verticalSpacing will be determined by the angle of your tiles. Set those to match however you make your art.
Drawing moving sprites will be a bit trickier because you'll have to decide which set of axes to follow... meaning, do you follow the axes of the screen, or the axes of your "rotated world." Give that some thought and once you understand what's happening with the perspective here you'll be able to see which is easiest.
So there's your engine ;)
Now, as for the art itself, make them in png format, so that you can have the base of your images be diamond shape, but of course tiles for players and walls and stuff will extend above that diamond. Just don't let them get below the base of their diamond otherwise the tile that gets drawn below them will cut them off. And you don't want a character's feet cut off by the "floor" as he runs ;)
For your final question, don't let java skew the sprite. The only possible way to make it decent is if when you pick an angle, a 3D render takes your 3D world and it's 3D models and re-renders them at that angle; skewing is simply not capable of creating that illusion. The closest you could get is to simply squish the hight of your art to give the illusion that the camera is moving up, but since you can't expose things higher, like the top of your character's head (since the data doesn't exist in the "lower" version), it will be obviously funny looking.
Hope that answers your questions, and good luck! I would definitely like to see what you come up with.

Game and Ball Hit problem

Hello everyone, I am working on a game and was wondering if I could get some help. I have a ball that bounces around in a box, and place one small ball in the applet. I want to create an effect that when the ball that is moving comes into connect with the static ball, the moving ball bounces in the opposite direction. I used this:
if(x_pos - 100 < 2 & y_pos - 100 < 2 || 100-x_pos < 2 && 100 - y_pos < 2)
where x_pos and y_pos are for the moving ball, and 100 is the radius of the static ball. Should I use the Pythagoras theorem to do it?
Thank You In Advance for any help.

Use java.awt.Shape and its contains() method. It's a standard collision detection idiom.

my problem is simplly i cant get any data from the database (whatever the database it is, i test it with MS Access and MySQL server) when i use a bean, But if i put my connection statement in the JSP file thair is no problem... ???? !!!!
for example i have a class "Authentication" that have a method to test if the username and password is correct or not and return 1 if true, 0 if false, -1 if thair are some problem in connecting DB.
now if i create a normal java application that uses this method, it's work and no problems, BUT if i used a JSP page to use this method it's return allways -1

Problem with Java 5 and Oracle 10g JDBC driver

Hi All,
Currently we upgrade our web application to Java 5 and Oracle 10.2 JDBC driver. And we encountered a bug, when the user entered the information through UI and data didn't store into database (Oracle 9i). The problem is that this bug is not happend so often maybe once a day and this did not happen before we upgraded to Java 5 and Oracle 10.2 JDBC driver. Does anyone encounter the same problem ? Is this Java 5 problem or Oracle JDBC driver problem ?
Thanks,

sounds like a database problem...
Are you using a driver version that's supported for your database engine?
What else did you change? We once ran into a major bug in our application that had for 5 years been masked by performance problems in our hardware and infrastructure.
Once those were resolved the bug showed itself and caused tens of thousands of records to be erroneously inserted into our database every day.
It's certainly NOT a problem with your JVM (if it's a decent one, like the Sun implementation).
So it's either your database, your driver, your network (dropping packets???), or your application.
The upgrade may just have exposed something that was already there.
