Map and Camera Hull collision detection.

How would I detect if a BSP map and the Camera's Hull/elipsoid are colliding?

A simple bool is great.

Look at the Collison and LoadIrrFile examples.

LoadIrrFile and Collision both open and render the map, but it never actually detects collision with it.

It instead uses the FPS camera. Which I don't want.

EDIT:
I'm not trying to get it to react on collision, just to see if it intersects with the map.

Actually, what you need is not that far off from those examples. You load your scene, create triangle selectors for your geometry, and then run collision detection against the triangles from the selectors. Yo could steal the collision code from the ISceneManager::getCollisionResultPosition().

So far I have this:

Code: Select all

smgr->getSceneCollisionManager()->getCollisionResultPosition(selector,camera->getPosition()+core::vector3df(0,30,0),core::vector3df(30,50,30),core::vector3df(0,-10,0));

But I'm a bit confused as to where to get the other parameters.
I simply copied a bunch of those from

Code: Select all

		scene::ISceneNodeAnimator* anim = smgr->createCollisionResponseAnimator(
			selector, camera, core::vector3df(30,50,30),
			core::vector3df(0,-10,0),
        	core::vector3df(0,30,0));
		camera->addAnimator(anim);
		anim->drop();

I'm also using the Collision example as a base for testing things out.
