Sounds like an infinite loop. I don’t know which IDE you use, but in Eclipse you can run your game in debug mode. When it freezes, you can pause each thread on by another in the debug view. Then you will be able to see where your threads are in the code.
Please provide further details. Every single point is important for us. It could be anything… a deadlock, an infinite loop, a GPU driver crash, a GPU device failure…
Use VisualVM or jProfiler to analyze your threads when it freezes. Or can’t you see anything because your screen is black and you need to reset your PC? A frozen/black screen, but the sound is still playing is a sign of a GPU/PSU hardware failure.
no, the last frame of the scene is showing there, the mouse pointer can move but not work in-game nothing cant select, keyboard not working. just plays sound. and CPU usage increase fan speed.
I tried it on another computer, os, and different hardware.
This only works if you run from the command line. Then when your app locks up you have to switch to the command line window and hit ctrl-break.
From your other posts, it does sound like you have an infinite loop somewhere in your code where it just runs and runs in a circle using 100% CPU. So another approach would be to comment things out to see if things start working again.
