Hello,
I wonder how my game can handle different display sizes.

In desktop game, we can set fullscreen to a standard resolution (800x600).

Mobiles have an standard resolution?
Which is the best way to handle this?

I tried it, but I expect 16fps and I get up to 30fps  .

Well, I suspect its because this resturns milis, not nanos... 

I don't know how  .

With J2ME I use System.nanoSeconds(), but J2ME doesn't have it.
Any example J2ME game loop 

Thanks!

yes, I know there's no practical way.

I just like to prevent the "casual thief"  .

I never heard about 64Kb limit, thanks!

BTW, Im trying to find a way to encrypt my resources.

Hello again, I used to compile my resources when I was programming in c++.
I mean, convert resources files (images, etc...) to .cpp files (.java this time).

Is there something to do it in the standard api?

Hi, I like to use an obsfucator (free), which do you recommend?

It creates a new image object  ?.

Is there a way to draw an scaled image directly on the graphics?

I googled a lot, but I couldn't it  .

I need to draw my image into a Graphics2D using linear interpolation:
I need something like:


There's a drawImage() method, but it doesn't stretch the image using linear interpolation.

cool, I'll take a look   .

...thanks again

Thanks for your reply.

Hello again, I have another question.

Some small devices are faster than others, this will affect my game fps or it is handled (somehow) by J2ME?.

Hello, Im new with small devices programming.

While I was reading some info about J2ME, I thought something;
in the future small devices will be able to run the standar java virtual machine, right?.

This "future" it's far or near?

oh, then I can't use these libs  .

Well, anyway, that space invaders tutorial explains what I was looking for,
Thanks again!

THANKS A LOT!

you help me a lot.
I like something simple, I write 2d games.
These libs JInput, JOGL, LWJGL are 100% portable, right?.

Thanks for your reply  .

Now I need:
1) Catch inputs events and store them.
2) Double Buffer
3) Run the game at constant rate

1) For the key events, I store each key state in a variable, set it true when its pressed and false when its released?. How is the best mechanism?
The only way to "listen" those events is implementing the Component interface? (The only way I know to read inpur is with Component addKeyListener. Is there another way?)

2) this is ok?:
class Screen extends JPanel {
   Image buffer = createImage(300,200);
   public getGraphics getGrapchis() { return buffer.getGraphics(); }
   public void flush() { buffer.dispose(); }
}

3) What should I use for run the game a constant rate?, should I use Threads?
EDIT
I don't like to use extensions, there isn't another way? 

Hello people!,
I was programming games in c++, and now Im moving to Java world  .

In my game design, I use a GameContext interface:


And a GamePlayer, that plays the GameContext:


My question is how the main game loop is coded in java, which classes should I use, and how?.
(I already now the FPS and that stuff, but I don't know how to code it, the API is huge!!!  )
I read some books and tutorials, but they are old or very confusing  .

Thanks in advance!
