Hello,

I tried to make a little test :

Code:

public static void printRemainingMem()
{
   long totalMem = Runtime.getRuntime().totalMemory();
   long freeMem = Runtime.getRuntime().freeMemory();
   
   System.out.println("usedMem="+(totalMem - freeMem));

   return ;
}

@Override
protected void loopIteration( long gameTime, long frameTime, TimingMode tm )
{
   super.loopIteration(gameTime, frameTime, tm);

   RectBillboard test =  new RectBillboard(1, 1, "ressources/particle1.png");
   test = null;

   System.gc();
   GraphicsCore.printRemainingMem();
   
   return;
}

There seem to have a memory leak but i don't know how to remove this kind of object.
There's no problem to detach them but is there a method to delete "in a clean way" the instance ?


Thanks

In this code fragment is no error. I guess, you forgot to properly detach it from the scenegraph or something.

What do you want to do with this rectangle?

In fact, i realized that i could resolve my problems on JOPS by coding on my own a very light little (and easy to use) particle system on xith3d. I thought it was a good exercise.
The results are quite good for the moment and i'll soon be able to implement it in my little game but i have a problem. I made a stress test (1000 particles generated per second, for 2 hours) and a realized that there was a memory leak.
I read my code and i didn't found the problem, i detach the particles when they are dead, ...

I wrote the little test on my first post and i saw that when you instanciate a RectBillboard, don't attach it to anything, set the instance to null (so in theory the garbage collector should take care of this) then there is a memory leak.

I looked for a method of RectBillboard to "release" all the ressources but i didn't found it.
