When I use physics engine I get error message

[cathy_1966]

Hey guys,
So I still am having this problem. Play level crashes and messages states edrt.exe has stopped working and I have to close the program. I am confused about physics. The tutorials I have done don't really mention physics. I feel like I'm missing a big part of the picture. Are there rules like you can't use physics with non-physical movements? Looking for some clarification. Thanks.

I'm curious too - is this a bug with Physical movements or is there a logical reason for the crash in this case(I attached a small example with the crash):
I assume the crash has something to do with bad instances of the same object in the frame or something like that.

(I uploaded the image with the problem events from your old post again.)

Wodjanoi,
Check this out. I ran your test application and it crashed with the same message! So what does that mean? Is it my program or my code? I had the two different launch areas so there would be enemies coming at the player at different places and speeds.
