I just followed blendercookie’s tutorial on how to break a cup with the BGE. Everything works just fine, but when I want to record it to IPO curves something strange happens.
It is set up as follows: all individual shards have suspended dynamics until they are touched by a box with a certain material which restores the dynamics. The box is animated manually and followed by a bullet which is also hand animated. Now the problem is when I play the animation in the viewport, the box and the bullet follow each other perfectly. The same thing happens when I simulate the entire thing in the BGE. But when I want to record the scene to keyframes, all of a sudden my box moves way faster than the bullet, so all the shards start moving before the bullet has hit it.
I already tried parenting the box to the bullet, but that way the touch-sensor won’t work. Can anybody help me out on this?
