Does anyone have an example or article on how to handle colliding, at an angle, with say a wall. I would like to slide along the wall instead of stopping
You need 3 things:
- collision point (tuple3f)
- original end point (tuple3f)
- colliding plane normal (vector3f)
The new end destination is projected by the normal of the colliding plane.
some psuedo code for the process using the vecmath library.
projectVec = new Vector3f();
newEndPoint = new Tuple3f();
newEndPoint.scaleAdd(-projectVec.dot(collidingPlaneNormal), collidingPlaneNormal, origEndPoint);
This should work... Of course optimize it for your need. Also remember that the new end point also needs to be checked for a collision between the 1st colliding point as well.
