// Description : A specialized kind of CollisionHandler that sets the
|
|
// Z height of the collider to a fixed linear offset
|
|
// from the highest detected collision point each frame.
|
|
// It's intended to implement walking around on a floor
|
|
// of varying height by casting a ray down from the
|
|
// avatar's head.
