collision is about to get a lot better in v1.6 and parts of my current project are on hold a bit until that comes out. the current built-in implementation does not allow you to know a collision actually occurred. the updated version has a collision callback system so you can actually be notified when a collision occurs.

Irrlicht is a bit different than B3D in that most of the tools are there but you need to wrap it up a bit to make it work. it will take me a bit to whip up a few examples. in the meantime you can review the source of iB3D for some collision stuff.

essentially, sphere-sphere detection and response will need to be all manual. box-box is manual. box-boxmesh (you can create a mesh from a box for collision purposes) is built-in but you dont know when a collision happens. box-mesh is built-in. mesh-mesh is manual.

Hi, I saw the 7th tutorial on how to create collisions between a mesh and a level.
I used the code succesfully, but what is the best way to see if 2 meshes collide?
Or lets say you have 50 planes flying around what would be the best way to detect collisions?

Tutorial 7 uses triangle versus sphere which might be too slow for 50 planes

is there a way of doing sphere-sphere?

and how do you detect colliisons in code?(e.g. bullet vs plane)

thanks
