Game Creation

I have an old dance mat and want to practice my Java skills so I'm looking at building a dance mat game for my evil Vista PC.
The dance mat seems to configure with windows perfectly but I haven't tried to experiment with listener classes to see if I can get it to work. I going to try the KeyListener class but does anyone have any idea if this will work, and if not how can I build my own Lister class to receive input or what other class should I use?
Also I want to be able to take control of the full screen in the same way as any other video game. Can I just use the JWindow class and set the size to the same resolution as my desktop? Also how can I change my monitors resolution using Java?

Game creation - HELP ME!

Finding a decent, free flash 8 tutorial on the internet for game creation, is no easy task. I have been through this frustration time and time again, and I am getting nowhere. My actionscript is very basic and I desperately need something to go on.
I have a game project, in which I have an enemy. One enemy. I would like to duplicate this enemy until there are five on the screen at once, and when I hit my enemies, more will appear as a constant wave of enemies until the character dies.
How can I do this?

As mentioned, the help documents and Google are some of the best resources for all levels of users. You can find FREE information/tutorials on just about every aspect of Flash. Another good approach is to pick a project, get to work on it, and use these tools as needed to solve the design puzzles you are confronted with. That's pretty much how I've always done things.
I've already pointed you in the direction for what you need to look into for dynamically adding new instances of things, so your first stop should be in the help documents to see what that method involves. And if there isn't enough information there for you to comfortably start trying things, then search Google.

Game creation on a mac

I know this might not be the right place to post this sort of topic...but, I was wondering what the best tools are for game creation on a mac. I have heard Unity and Torque Gam Engine are good ones but I am hopefully looking toward something that is freeware. Any suggestions?
I have heard there are engines for Unreal and Quake, etc that are free...

Snapz Pro supports digital audio capture, and microphone capture.
Check This Page out. There's trial download available.
Regarding the timing of the subtitles or captions in iMovie, what I did was to place the playhead (the moving triangle) where I wanted the subtitle inserted (the subtitle starts from that very point, and lasts as long as you set it in the Speed slider), Edit/Split Video Clip at Playhead and then dragged the subtitle from the gallery to that place in the timeline.
Some subtitles can last up to a few seconds, and ohers, like "Music Video", up to ten minutes.

Is Adobe AIR/Flex good to begin in game creation ?

Hi all !
I have a little question, I want to begin to learn how to create little games (2D games first) (I'm more a Web/Server Side Programmer/Administrator than a Desktop pPogrammer), and I would like to know is Adobe AIR/Flex (without using the Flash IDE if possible) is good for that ?
It looks a lot easer than the others ways (Java, C++, python), no needs to think in "threads","mutex",etc and other things like that, and the multimedia API help a lot for the video/sound side
So, what about creating games with Adobe AIR ? What about performances ? Is it possible to create 3D games ?
Thank you !

Personally I'm still debating whether to start learning iPhone development or AIR at this particular point.
At any rate, anything you can do in Flash you can do in Air, so I'd probably start with the Kongregate game creation tutorial. It's AS2 not AS3, but it will give you an idea what you can accomplish with a couple hours of development.
No idea how good it is for 3D, but a lot of those "virtual tour" things are done in Flash. Probably not your best starting point if your plan is to make your own FPS but...

Simple/newbie 2D game creation

this is my first attempt at creating any game. i am unsure how to even begin creating a simple 2D game similar to old "Hugo's House Of Horrors" for dos. It's kind of like the final fight in the way the characters move through the environment. any help is appreciated

the first step is to sit down and write on paper, this has helped me, and plan the game out. The main points in animation/game creation is the x and y coordinates u must understand those like u would english. then the if statements that come with determining if one object ( a space ship ) is in in another objects ( enemy space ship ) space or the same x and y coordinate...remember u must always map everything out.
www.google.com search: java game programming
that should set u on your way..

Few questions - game loop, data types, speed

Hello, I have a few questions after studying some topics in this forum regarding game creation:
1) What's the fastest way to wait in the game loop? I've seen two approaches:
thread.sleep(10)andsynchronized(this) { wait(10); }2) What data types shall I use? In C++ I use to prefer int over short in all cases, because 32bit hardware works faster with integers. Is this same on cell phones?
3) Speed of applications is slow. I just wonder wheter it's my fault. I was testing application, which only cleared the buffer and outputted FPS and I got around 20 frames. It was Nokia 6300 with 240x320 display. After testing on other phones I've found out that the bigger the resolution, the slower the game is going. Is this normal?
Thanks for replies...

1) You're not going to notice any really speed difference between the two code snippets. Read up on 'Threads', and you'll see why one may be used in place of the other depending on the situation. In general there may be a slight performance loss, however unnoticable, when using the synchronized version, but when you are multithreading it is likely necessary.
sleep(int) is impossible to interrupt, so it's generally a no-no in most situations. However we are talking about devices where every bit of performance helps, so as long as it works for ya, it's not a big deal.
2) The performance difference is fairly negligable, if any. The biggest thing to consider is memory requirements, and shorts take 1/2 the data.
Also, many phones don't support floating point data types, so you'll likely need to use ints/longs to calculate your values if you want to have any accuracy beyond whole numbers. Doing something like shifting bits or using 1000x values in your calculations can get around most of the problems when you can't use floats.
3) The biggest performance killers are IO, memory allocation, screen drawing; pretty much in that order. So I imagine that you are re-creating a new String object every time you output your FPS value on screen right? Doing that every frame would destroy any hopes of getting high-performance.
Just be careful, and never allocate objects when you can avoid it. anything where you concat String objects using + will cause your performance to die a horrible painful slow death. Remove anything that says 'new' from your main loop, and all String operations, and it'll likely speed things up a lot for ya.
Does your main loop have something like this?
g.drawString("FPS: " + currentFps, 0,0,Graphics.TOP | Graphics.LEFT);
This is very bad because of the String operation. It'll create a new String every frame.

[SOLVED] Best language for coding games

Hi All,
My son has been learning BASIC-256 and he's interested in writing games. Can someone recommend a programming language useful for that purpose. He's young so easier would be better than harder but he's quite determined so I'd be interested in knowing what people are using nowadays as the hot gaming language.
Thanks

Thanks to everyone for the thoughtful replies. It looks like many are in agreement that python might be a good step up from BASIC-256. I did some reading but I would appreciate some clarification on which version to use, python, python2 or python3 (I really don't understand how significant the differences are). As companions to python many things have been mentioned: blender, allegro, SDL, PyGame, Löve, SFML, Python-Ogre and PyGTK. Any thoughts on which of these might be the easiest to deal with, (or none)?
Daedalus1 wrote:For a beginner writing 2d games, python2 would probably be the best choice.
You could also use PyGTK to make games since all you really need for a 2d game is a way to draw graphics.Python is a good "gateway language" to more advanced languages, and it's useful for scripting so it has it's uses even if he moves on to the next tier.
That sounds pretty good.
bananaoomarang wrote:Certainly Python with Pygame would be good for starting out right now, Love looks awesome to, though I find Python easier to read than Lisp, just a personal opinion.
Thirty five years ago when I was at university studying music composition, one of my music teachers was also teaching a class on Lisp (lots of irritating silly parentheses) I took the class and for the good of all I decided to stick with music. Actually, I've been enjoying learning BASIC-256 with my son, maybe, after all these years I should take another look at Lisp.
drcouzelis wrote:I realized a few years ago that my hobby isn't "making video games". Instead, it's "programming video games". In the former, there's more focus on creating a fun game, creating the graphics, and doing everything as simply and easy as possible with the single goal of having a finished video game. In the latter (the one I enjoy), I don't care that in the past 12 years I've never finished making a video game. I enjoy tinkering with fairly low level graphics engines, implementing simple physics, and seeing the game come together one small piece at a time. I enjoy the programming.
Very good point, I've noticed that even though my son constantly thinks (and talks) about the details of his game creation, he seems to also enjoy just playing with BASIC-256. I also can relate to this as a composer, thinking and conceptualizing about the organization of sound has brought me as much pleasure as finishing a composition. Process rather than goal orientation.

It looks like it is about a game running on a phone but python is cross platform so you can ignore that and follow the tutorial on linux or whatever. Just install python2 and pygame for him.
I looked at it briefly and it looks promising for someone at my (his) level.
Thanks again to all of you for taking the time to enlighten an otherwise clueless person, drifting aimlessly on the sea of mysterious computer stuff.
I'm retired and there are only 6 more days of school here (we live in the Phoenix area and they have to stop the school year in May, otherwise the children would end up being just little charcoal blobs on the playground) so I'll have lots of time to work with my son through the summer.

I previously had this problem on two 15" MBPs and fixed it on both by downing the following:
1.) Install 10.4.6 update
2.) Delete system keychain entry and any login keychain entries for the wireless network
3.) Go back to System Preferences -> Network and re-enter the login and password for the network.
Since then they have both reconnected to the network automatically with no problem. Before that I had the same symptoms you describe.
Thanks for replying. The issue that I have to go
through with my 15" is that whenever it sleeps or I
reboot I have to turn off Airport, turn it back on,
find my wireless network and reconnect. The guy I
talked to at the Apple store told me that was normal,
but I have never had to do that with other laptops I
have owned nor do I need to do that when I boot into
XP using boot camp. <shrug> Just wondered if that was
common to all MBP's, just the 15 or just mine hehe.

Games contest

i like to know is there any games contest.. if yest pls let me know

Hey all, Im gonna start an 8k game creation contest
with quality PRIZES. since java is not under 8k, a game in java under 8k is
not really 8k, so why bother at all ?by that logic, no program written in any language for any platform can be realy less than 8k, as they all have some form of dependancies.

Resizing pixel art video without affecting the pixels with blur.

Hello everyone,
First I would like to mention that I did searched for an answer to my issue on the forum but only found a thread by Rowby Goren from Jan 4, 2010, who asked a similar pixel resize question regarding to still images in CS4. He was answered to use Photoshop for this kind of task. My issue on the other hand is for handling a video that can only be edited in Premiere. I'm using CS6. My issue is as follows:
I work a lot with pixel art animation in 320x240 resolution. Usually I'm making a 320x240 scene of background and characters and the final result should be a doubled sized. So each pixel is actually 2 times larger. Just like old adventure games from the good old days that most of us remember. It works great with old style games creation engines however when I want to make a video with my pixel art creation in Premiere, I couldn't achieve an exact and clean doubled pixel when resizing the source by 200%. It always gets blurry. Does anyone knows if Premiere has any switch off option for scalling blur?
I have created an image that describes the issue. It's just a simple pixel art image that I picked up on google search. I saved and uploaded it as PNG for best quality, I just hope it won't get compressed after the upload. Any assitance will be appreciated!
Thanks,
Gal Shemesh

Thanks Jim, I am aware of the fact that it's a degraded image that doesn't have any antializing effect on it. And that's what I'm trying to achieve in Premiere, although it's currently impossible. Until now I'm doing exactly what you suggested, which is to double the size in Photoshop or other tool that doesn't affect any antializing on the image and then I import it into Premiere. However this also makes a problem when you want to move objects on the screen as the imported images which are doubled size, won't show well on the 1:1 pixel grid when you move them around the screen. So let's say each move on the X axis to the left or right (which represents a move by 1 pixel) should be moved twice in order to meet the doubled sized images pixel grid.
Take a look on the picture I created to see what I mean. I've duplicated the box image and I'm trying to position each box one next to another in a 3d space look. The left boxes is the original image of the 2 boxes, and the right image is the doubled sized image that was created outside of Premiere. Please note that I've the entire screenshot twice larger so you could see the difference. And please ignore the fact that there is no antializing on the right image as I made this simulation in Photoshop so the pixels will be clean to show the problem.
So, if you aware of how a pixel grid looks like, check the left image. The position of the boxes on each other is the way it should be as each pixel from each box keeps the relation of a 1:1 pixel grid. However on the right image I first doubled the original box image to prevent 'blurring' effect when scalling up in Premiere, put it on a 1:1 pixel canvas (where the image has 2:2 pixel grid by now) just like how it will be in Premiere, and tried to position the boxes one next to another. See that there's a confusion between the pixels on the 1:1 grid as they got merged one INTO another without saving the relation of a doubled pixel grid. Where if there was any option to work in doubled sized pixles in Premiere, it would have look like this:
So importing a doubled size images into Premiere like you suggested is way hard to keep tracking the moving objects in the scene, as you must remember to move them twice the times to each direction. Which means that if you want to move an object from one side of the screen to the other side, you'll have to do it frame by frame in a move of 2 pixels by frame, rather then positioning it in one place, make a keyframe, and then go to where the movement should end and place another keyframe.
Hope now my issue is clear.
All the best,
Gal Shemesh

Help: Factory Class using Inner Class and Private Constructor?

The situation is as follows:
I want a GamesCollection class that instantiates Game objects by looking up the information needed from a database. I would like to use Game outside of GamesCollection, but only have it instantiated by GamesCollection to ensure the game actually exist. Each Game object is linked to a database record. If a Game object exist, it must also exist in the database. Game objects can never be removed from the database.
I thought about making the Game object an inner class of GamesCollection, but this means that Game class constructor is still visible outside. So what if I made Game constructor private? Well, now I can't create Game objects without a static method inside Game class (static Object factory).
Basically what I need is a constructor for the inner Game class accessible to GamesCollection, but not to the rest of the world (including packages). Is there a way to do this?

leesiulung wrote:
As a second look, I was initially confused about your first implementation, but it now makes more sense.
Let me make sure I understand this:
- the interface is needed to make the class accessible outside the outer classBetter: it is necessary to have a type that is accessible outside of GameCollection -- what else could be the return type of instance?
- the instance() method is the object factory
- the private modifier for the inner class is to prevent outside classes to instantiate this objectRight.
However, is a private inner class accessible in the outer class? Try it and see.
How does this affect private/public modifiers on inner classes?Take about five minutes and write a few tests. That should answer any questions you may have.
How do instantiate a GameImpl object? This basically goes back to the first question.Filling out the initial solution:
public interface Game {
    String method();
public class GameCollection {
    private static class GameImpl implements Game {
        public String method() {
            return "GameImpl";
    public Game instance() {
        return new GameImpl();
    public static void main(String[] args) {
        GameCollection app = new GameCollection();
        Game game = app.instance();
        System.out.println(game.method());
}Even if you were not interested in controlling game creation, defining interfaces for key concepts like Game is always going to be a good idea. Consider how you will write testing code, for example. How will you mock Game?

Help with scrolling background

i am following a tutorial and in it, when the Hero hits a
wall he respawns somewhere on the screen. The problem with that
was, that i didnt know where he would respawn. And In order to make
the maze bigger i used a scrolling background and I couldnt figure
out how to change the respawn location either. Here is the site
that I am following the tutorial from
http://www.emanueleferonato.com/2007/02/09/flash-game-creation-tutorial-part-51/

Strange Line In problem with my X-Fi Elite Pro. Stereo sound comes and goes

I have an X-Fi Elite Pro with latest drivers installed. Everything works fine, except for the Line In port in Entertainment mode. I have an AverMedia TV/FM card and its audio output (stereo) is plugged in my X-Fi's Line In/Mic In (PCI). The problem is that I get sound only from the right channel but not from the left one, so the sound comes out in mono. From time to time, I get to hear in stereo (both channels) but it seems a random event. This input works just fine in Game and Creation modes btw.
Stereo sound from this particular input comes and goes in random order and sometimes I get about 50% on the left and 00% on the right channel. Sometimes, left channel volume fades in and out slowly. I already did some troubleshooting such as set Line in/Mic In/Digital In to "Line In/Mic In", speaker diagnostics, checked it in Game & Creation modes, turned to default values and so on but I still get this problem.
Seems pretty wired. A ghost in the machine! Creative products never seize to amaze us!

Soo...your're calling me stupid? Well, perhaps your right, but then again, I might have a point!
Read my post again.
If you still think it's too low with SVM enabled and everything is turned up...then I'm affraid you're out of luck and might consider buying another speaker set, if it's a major issue to you.
