I need to hit a wall. Literally. I have a player, who can collide with other objects via my BoundingSphereCollide() method in which I check if the player has collided with the objects bounding sphere with the intersects() method, works perfectly. Now I need a PlaneCollide() method, but the Plane.Intersects() method is weird, how would I go about making it work? there are things about matrices and quaternions, I know nothing about either. what would the matrix contain? I have looked up quaternions, and I don't think thats the direction I'm going in.

 or possibly I'm going about this the wrong way, is there a way to find the width/height of a mesh or model? because then I would just create a bounding box, or my own type of intersection plane.

Thanks ahead of time,
