How to find where to cast a ray to avoid collision in Bullet? http://stackoverflow.com/questions/14326654/how-to-find-where-to-cast-a-ray-to-avoid-collision-in-bullet to find where to cast a ray to avoid collision in Bullet Say we have an object at point.. velocity so it can only move step by step. It casts a ray at direction it is moving to. Ray collides with an object and.. an object and we detect it. How to get a way to pass our ray safely avoiding collision btw is there a way to make such thing..
