I agree with Nikolai, but I am not sure if just setting wakeupOnElapsedFrame with passive = true will solve the 100% CPU usage problem.
Seens the frames elapsed becouse behavior waked-up and the behavior wakeup becouse frames elapsed. I think this is kind of dead-lock, maybe in the inverse mode, using more cpu resources. (like a dog trying to bite his own tail hehehehe) I re-wrote HelloUniverse using a 2 new versions of RotateInterpolator (both using a new TransformInterpolator): one using wakeupOnElapsedFrame and the other using wakeupOnElapsedTime. Using wakeupOnElapsedFrame version under Win2k I found 100% CPU usage, and using wakeupOnElapsedTime version (Win2K again) I found very low CPU usage. Maybe I wrote it wrong, or maybe I am not using wakeupOnElapsedFrames correctly, but if I am right wakeupOnElapsedFrames(0) uses more CPU cycles than expected or needed. And, in this case, may we need behaviors with wakeupOnElapsedFrame(0), active, without waisted CPU cycles. I pass the word to jedi masters over here ;) Alessandro related bug : http://developer.java.sun.com/developer/bugParade/bugs/4774349.html ----- Original Message ----- From: "Nikolai V.
