J2ME game gui? J2ME Canvas? J2ME polish? Which is better?

I am currently trying to build a J2ME brochure like project which is required to have rich presentation.
JAVA is not a problem for me as I've used it for quite a long time. But since I am very new in J2ME, I am confused which technology to use, should I use j2me game gui, j2me canvas or j2me polish?
Using j2me game gui looks good. J2me canvas looks a bit tedious to me because for a brochure like project, it will mean I will probably end up using a lot of canvas which make the application quite big. Regarding to J2ME polish, there is not many materials or examples about it. it seems that J2ME polish hasn't been used a lot and I don't know whether it's good or not.
Anybody knows something about those three? Please give me a hand.
Thanks.

J2ME Polish have licensing costs associated with it:

As for Canvas VS GameCanvas:
GameCanvas is MIDP 2.0 and up, so depending which devices your app supports you might want to stick with Canvas. GameCanvas eases graphics flushing, but double buffering can be implemented on Canvas like so:
Image offscreen = isDoubleBuffered () ? null :
Image.createImage (getWidth (), getHeight ());See http://www.developer.com/java/j2me/article.php/10934_1561591_8

J2ME game timer

Hi,
I am developing a J2ME game. At the moment i have code which will terminate the game if the game is reaches the time set.
Now i want to be able to display the count down on the actual game. I want to display it anywhere on the screen but im not sure what i really need to implement to physically the actual counter.
Can anybody help.
Thanks

Problem solved. :)
Comments are welcome. :)
    public void run()
        int millis_per_tick = 100;
        int counter = 1000/millis_per_tick;
        timeLeftInMillis = 180000;
        Thread currentThread = Thread.currentThread();
        try
            // This ends when myThread is set to null, or when
            // it is subsequently set to a new thread; either way, the
            // current thread should terminate.
            while (currentThread == myThread)
                long startTime = System.currentTimeMillis();
                repaint(0, 0, screenWidth, screenHeight);
                serviceRepaints();
                long timeTaken = System.currentTimeMillis() - startTime;
                if (timeTaken < millis_per_tick)

                if (counter == 0) {
                    timeLeftInMillis = timeLeftInMillis - 1000;
                    counter = 1000/millis_per_tick;
                else
                    counter--;

I solved the same problem by using indexed color images instead of true color.
So, for example, if you have a colorful background you can convert it to a 256 color image.
Depending on your specific image and the devices you'll see it on you may or may not notice the difference, but the file size is generally smaller.
Then you can push further for smaller elements, like, say, a moving object like a pointer or a starship, you can reduce it to 60 or 30 colors, or even less.
Another technique is to use tiles to build up the background instead of big images. With MIDP2.0 there's the TiledLayer, but you can implement the same with some code also on MIDP1.0 if backward compatibility is of concern.

J2ME game project advice

Hey guys, i was hoping to get some advice on a project i am about to start. basically I have just started learning J2ME, using Netbeans. i have went through few tutorials from Hello World to Pong and completed them working fully. Now my project is something not too difficult I hope what i wanted to do was create a dungeons and dragons type game.
Basically I see my game as a start screen, the user presses start and then the player enters a castle and then there are either 1-4 doors available to walk into one on each side of the screen, the bottom door will always be to take the player to the previous screen.
I have just started the project, but before I even enter any code i was hoping I could get some advice form you guys first. IN each room I hope to have things for teh player to interact with, wether it is a treasure chest, dragon, another human or traps, I have not decided yet.
I was thinking of having a class one for each screen, but many screens means many classes. I am not even sure how to start with the titlescreen as i am completely new to J2ME.
any help would greatly appreciated!
Thanks!

I was thinking of having a class one for each screen, but many screens means many classes. I am not even sure how to start with the titlescreen as i am completely new to J2ME.No, that is not what you want. Like you should always do in programming, do-not-start-with-the-code. Very bad practice!
Start with a piece of paper and draw some simple screen designs. Menu, in game screen, control widgets, etc. Get something visual going quickly.
Next, Use some proper non-programming related terms to describe the game and stick to them. You do not have screens, you have rooms. Each room has doors in its walls which leads to another room. All the rooms together form a maze. Each room has different properties. It can have 1-4 doors, it might hold an item, a trap, an enemy, etc.
Given from the short description I have given you, you should already be able to distill a simple design. You can already easily identify two main classes: Maze and Room. A Maze consists of rooms. Each room links to 1-4 other rooms through a door. Each room has zero or more elements in it which are different from room to room. You will want to be able to control per room what it contains. I smell a simple grid based data structure; but then you still need a way to actually create the data for the game. There are two basic options: create a level editor, or auto-generate the mazes based on some simple rules. The latter would be the best choice in this case, as you get endless levels. The former has the benefit of having precise control over the design and difficultly of a maze.
Auto generated levels become more difficult when you want to add an option to save progress though, as you'd need to be able to not only recreate the level (hint: generate based on a seed) but also restore the progress that the player made in that level. Its up to you really.
When you have your game fleshed out, its time to start taking the technology into account. You'll have a nice set of functional and technical requirements that you need to fulfill; a good resource on J2ME game programming will probably help you to fulfill most of them. Don't expect to just be able to do this, you'll need to study J2ME a lot and probably do a whole set of test and play programs before to figure out how to do even the simplest things. I recommend you get a good book in stead of trying to piece it together using the internet, in moments like this you need something coherent in stead of something as fragmented as the web.

J2ME Game

Hi all, i am making a J2ME game for my mobile(Nokia 7210). But i meet a problem that my mobile is just support MIDP1.0 that is no media api. I know sun provided Mobile Media API, can i use it? But the VM in the mobile do not have the classes, how can it run? Or can i attach the media api classes with my MIDLet game and run directly? If yes, how can i attach it?
Please help me. Thanks a lot.

And I forgot to mention, those classes (and a bunch of other Nokia extension classes) can be found on any of the Nokia SDKs on their site. And you're in luck because there's one specially made for the 7210.

Looking for J2ME Game Tutorial

Hi,
I really want to start writing J2ME Game, however, at least, I need some source codes before doing anything. Is there any moving Hello World Game? Joking.
Would u please suggest me where can I find more about J2ME Game, especially source code. I need them in urgent. THx.

When you download the WTK 2.0 (from this site), you get example applications. Included are 3 (I think) nifty games. I also know that the Nokia SDK also comes with an example of a J2ME game.
I think that if you are familiar with Java you don't need much than that to start writing your own games.

Hi,
Just want to share a J2ME game that I've developed..
http://limingchina.googlepages.com/puyopuyo
Current version is 0.3. Both jar file and source code are available.
Tested on N73, N81. Should work for most java phones.
(Known issues: counterclockwise rotation is not implemented correctly, will be fixed in version 0.4)
It's developed using Netbeans. Recently the project file is
updated to Netbeans 6.0.
Have fun!

Send J2me game score via GPRS

I'm able to send data from j2me game from a different PC emulator to another server's tomcat
but when i try to send on real hp 7210, my server's tomcat didnt recieve the data?
anyone noe y?
urgent.....

Some cellular providers set up their gateways so that they block anything that is not destined to port 80. What access point are you using on your phone for the connection. If you are using a WAP access point then this might be the case (since servlets listen on port 8080).
In this case try using an internet access point (setting the gateway IP to 0.0.0.0), or use some redirection scheme on your server and send your requests to port 80 (I'm not very familiar with this but I remember someone talking about using something called ISAPI redirection or something for this).

Open GL Vs Quartz - Which is better for 2D game development?

Hi,
I am new to iphone game development. I want to create 2D game. Simple game with objects moving around.
I never used Open GL as well as Quartz. For this game I am planing to study that.
I want to know which is better from OpenGL or Quartz?
And where I can learn more on that?
Thanks,
Ganesh Pisal

I would recommend against OpenGL for a 2D game. Quartz does a lot of work to avoid updating parts of the screen that haven't changed, something OpenGL doesn't do. The iPhone's implementation of OpenGL has other serious performance issues.

Is there an alternative control for canvas in SAPUI5 which is responsive?

Hello,
I followed Electronic Signature using SAPUI5? for electronic signature. I could integrate it easily.
I have few questions; In signature lib <canvas> is used. Is there any control in SAPUI5 I can use for <canvas>. I have xml views, I am adding the canvas from js controller to <core:HTML id="signature" />.
This way <canvas> is not responsive.
If there is no alternative control in SAPUI5, Is there a control where I can place the canvas from controller which would make canvas responsive without additional coding?
Thanks,
Rashmi

Yes, it would work, but I'm not entirely sure it would be the most obvious way for a motion designer to go about it. I'm trying to make it as easy as possible for a non-advanced AE user to change a string. So, I though of using the Layer Select expression control, then have a null object resting in the comp with a placeholder name. Then, the user could change the layer name of the null object, and select that layer from the drop down in the expression control. Then my script could read the value of the name for that selected layer.
I just wanted to avoid having anything actually in the comp layer. Your suggestion would mean they would have to unhide something, type out the string, then hide it again so it wouldn't render. Thank you for your suggestion, it got me thinking of alternative ways to handle it
Best,

Which is better, Double Buffering 1, or Double Buffering 2??

Hi,
I came across a book that uses a completely different approach to double buffering. I use this method:
private Graphics dbg;
private Image dbImage;
public void update() {
if (dbImage == null) {
    dbImage = createImage(this.getSize().width, this.getSize().height);
    dbg = dbImage.getGraphics();
dbg.setColor(this.getBackground());
dbg.fillRect(0, 0, this.getSize().width, this.getSize().height);
dbg.setColor(this.getForeground());
paint(dbg);
g.drawImage(dbImage, 0, 0, this);
}that was my method for double buffering, and this is the books method:
import java.awt.*;
public class DB extends Canvas {
     private Image[] backing = new Image[2];
     private int imageToDraw = 0;
     private int imageNotDraw = 1;
     public void update(Graphics g) {
          paint(g);
     public synchronized void paint(Graphics g) {
          g.drawImage(backing[imageToDraw], 0, 0, this);
     public void addNotify() {
          super.addNotify();
          backing[0] = createImage(400, 400);
          backing[1] = createImage(400, 400);
          setSize(400, 400);
          new Thread(
               new Runnable() {
                    private int direction = 1;
                    private int position = 0;
                    public void run() {
                         while (true) {
                              try {
                                   Thread.sleep(10);
                              }catch (InterruptedException ex) {
                              Graphics g = backing[imageNotDraw].getGraphics();
                              g.clearRect(0, 0, 400, 400);
                                                g.setColor(Color.black);
                              g.drawOval(position, 200 - position, 400 - (2 * position), 72 * position);
                              synchronized (DB.this) {
                                   int temp = imageNotDraw;
                                   imageNotDraw = imageToDraw;
                                   imageToDraw = temp;
                              position += direction;
                              if (position > 199) {
                                   direction = -1;
                              }else if (position < 1) {
                                   direction = 1;
                              repaint();
          ).start();
     public static void main(String args[]) {
          Frame f = new Frame("Double Buffering");
          f.add(new DB(), BorderLayout.CENTER);
          f.pack();
          f.show();
}which is better? I noticed smoother animation with the later method.
Is there no difference? Or is it just a figment of my imagination??

To be fair if you download an applet all the class files are stored in your .jpi_cache, and depending on how that game requests its graphics sometimes they are stored there to, so really if you have to download an applet game twice, blame the programmer (I've probably got that dead wrong :B ).
But, what's wrong with Jars. They offer so much more.
No offence meant by this Malohkan but if you can't organize your downloaded files the internet must really be a landmine for you :)
Personally I'd be happy if I never seen another applet again, it seems java is tied to this legacy, and to the average computer user it seems that is all java is capable of.
Admitidly there are some very funky applets out here using lots of way over my head funky pixel tricks, but they would look so much better running full screen and offline.
