Can any body help to improve this game . I want the game to be dynamic and multithreaded..

[Ulf Dittmer]

Define "dynamic". What, exactly, does the code do now, and what, exactly, do you want it to do?

[Pradyumna Sahoo]

thnks for your reply , it's a simple awt shooting game but it's static one(means the objects are not moving). I want the tanks as well as the targets to move at the same time. i.e mutithreading

[Campbell Ritchie]

You cannot apply multiple threads to Swing components.
Suggest a Timer.

And please change the subject of this thread.

[Pradyumna Sahoo]

how do they develop games than!!!

Oh, and in this day and age you shouldn't be wasting time getting familiar with AWT. Swing superseded AWT more than ten years ago.

And if you want to be really cutting-edge, you should devote your time to learning JavaFX 2. It's still a little young, but maturing fast.
