And set up the camera logic so that the camera will move when a key is pressed. Watch the game crash when the camera starts to move. (and do note, the crash will only happen if you assign the controls to the camera).
The only BGE changes between 2.69 and today is the big code cleanup from Moguri, so I am almost certain that those changes introduced the crash, I’m thinking there must now be some sort of error with the view matrix or something but I can’t say for sure. All I know is that the Blender release cycle is right now in the initial phase where big changes are being done so it’s understandable to see some regressions early in the release Cycle.
If Moguri can look at this and resolve this quickly, then that would be great, thanks.
