I'm currently trying to implement a kind of cover system for a project of mine using the UDK.
Regardless of you guys knowing how the unreal script works the answer to my question should not depend on the development environment.

What I currently have is a check (ray trace) if my character collides with a wall.
Where I get the hitLocation and the hitNormal out of that.

Currently I do:

myLocation.Z = WallHitLocation.Z;
myLocation.Y = WallHitLocation.Y;

Which obviously does not work since I need to move along the wall but this does only work for moving my character along the Z and Y world axis.
Is there some math to let me move along the wall, having stuff like the wall's normal ?


Also a second question considering cover systems. If I want my character to overcome an obstacle that he's been hiding behind. How would I translate that to the actual change of character position? Do I have to mathematically define some kind of spline with controlpoints from my location to the location behind the cover and then interpolate this position during the animation?
