I there. I'm developing a RTS (Real time strategy) and experienced some performance problems with the following code. Moving Images and Animations and so on got frame laggs everytime a sound is played...

}


well its adapted for this post, but thats basically it... is there a better methode playing sounds ? I already advanced to this method from using AudioClips : DD


and... if I play a background music file with the following code, I got generell laggs all the time and the animation and movements are not constant anymore....

  {
   System.out.println("line not available!");
  }
  /*catch (InterruptedException e)
  {
   System.out.println("cancel!");
  }*/

 }
}


It seems these codes are working but are not designed for games like this because of the problems...

help : D

just to inform you: I'm using now EasyOgg and I'm very surprised in many ways of it.
And the lags are also gone.

I think the lag was because you load and play the sound in the same thread as the main game/render loop, which causes it to pause until the audio file is loaded
