Implement a collider in Python

Hi. I’m implementing an algorithm to efficiently do Ray->Heightmap collision tests. Now I’d like to make a proper collider object out of it, and ideally do so in Python before tackling C++.
So, can I implement a CollisionSolid purely in Python? If so, how do I go about it? Both Manual and API docs don’t seem to discuss the collision systems internals too clearly.

No, you can’t, sorry. You’ll have to implement it in C++.
