Hallo, marius schebella hat gesagt: // marius schebella wrote:
I just found out that setFixed does not immediately stop a mass, but the mass seems to keep the current speed/directions? only if I also send a position to the mass it stayes fixed. just want to make sure that this is intentional.
It's intentional and follows Newton's 1st law of motion, though the name "setFixed" may be misleading: What it does it, it makes a mass not respond to forces anymore. The effect is that it won't accelerate or decelerate anymore, which means it keeps its last velocity.
