In the C++, it's getContainer()->castRay(), and in script, containerCastRay (or something very similar).

They'll let you specify a line to test along (such as from the point to a point very high above it), an exclusion mask (so you can say, only test for terrain), and return the location and normal for the point they struck. Hope that helps.

is RayInfo an struct that holds the intersectiona and normal for the collision?
