fast collision between a mesh collider and a continuous dynamic rigidbody

Questions & Answers

My main object is very fast, and it's been going through my mesh colliders as if they didn't exist. I've been trying out Unity 3.0's collision detection options hoping that it will solve the problem.

But it seems like these options only apply for rigidbodies, and reading from:

Continuous - Used for objects which the Continuous Dynamic detection needs to collide with. Continuous Dynamic - Used for fast moving objects.

it seems as if I don't set one object on `continuous` and the other on `continuous dynamic`, it won't affect my collisions.

I have two questions:

  1. Should I still set my main rigidbody in `continuous` mode even though it will collide with a mesh collider?
  2. And is there anyway to give make my mesh the `continuous` property?

If your fast moving object has a rigidbody (it should), and you set that to "continuous dynamic", you should be fine for any collisions against:

-static mesh colliders.

-other rigidbodies with continuous collision detection enabled.

In other words, you don't need rigidbodies on the static meshes for CCD to work. You will need to add rigidbodies to primitive colliders, though.
