About Collision physics behaviour
Posted: Mon Sep 03, 2018 7:22 pm
Commented in the tip.
(1) When an impulse is given too low for the ball (for example ApplyEntityImpulse(bola.i,0.1,0,0,0,0,0) ), then the collision physics behaviour seems not correct.
(2) When make a rotation for a mesh then the physic body created after the transformation (rotation) seems not to be correct working for collision. I think it should work, because CreateEntityBody() is called after the mesh transformation, so CreateEntityBody() should catch the shape as it is.
