llGround

Summary

Function: float llGround( vector offset );

42	Function ID
0.0	Forced Delay
10.0	Energy

Returns a float that is the ground height directly below the prim position + offset

• vector

offset

–

offset relative to the prim's position and expressed in local coordinates

The requested position needs to be in the same region. Only the x and y coordinates in offset are important, the z component is ignored.
