While making a game I am stuck at following situation :
When I use a object A to hit another object B at a certain speed or higher than that, object B always overlap above object A. I have applied mesh collider to both the objects. Well, I will like both the objects to collide rather overlap each other. Anyone knows where I am going wrong ?
Sounds like object B is moving faster then the psychics engine can track it, as a result the collision isn’t detected till object B is overlapping object A. (or at even higher speeds object B will simply pass object A without collision)
You can try to lower the time between psychic steps but thats usually a bad idea.
(Edit → Project Settings → Time → Fixed Timestep)
A better solution would be to avoid using colliders with fast moving objects, a good alternative is to use a ray-cast to find collisions for those object.
Also use box colliders, mesh collider are bad for high collision impacts
Also, you should never use two mesh colliders unless one is set to convex.
@ Koen.pis - Changing Fixed Timestep does not work
@ Cat_Ninja - Box collider cannot be used my game as this will not give high precision impact.
@ jonbonazza - I have set both the mesh colliders as convex but still no luck.
Also I have set both object A and Object B to continuous dynamic collision but again no luck.
Can anybody help me out with this collider problem !!!
I have recently come across this. When running your project in unity, set the rigidbody’s Collision Detection Mode to CollisionDetectionMode.ContinuousDynamic. For some reason I’ve had this problem for a while and only setting it at run-time (post-instantiation) solves the problem. Doing it on Start or Awake does set the value but the ridigbody doesn’t act properlly until I set it to something else and then, back again during run-time.
