How to do a object like a camera rotate exactly 90°? I need to do a labyrinth like Window$ labyrinth screen saver and the camera need rotate 90° when reach a corner.
The best way would probably be using an IPO curve of rotation.
Save a keyframe of each of the 90 degree angles, with several frames inbetween for interpolation. Then simply use an IPO actuator to rotate the camera when needed.
