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.

<lsl>// Makes the object land on ground or on water

FindGroundOrWater() {

   vTarget.z = llGround( ZERO_VECTOR );
   float fWaterLevel = llWater( ZERO_VECTOR );
   if( vTarget.z < fWaterLevel )
       vTarget.z = fWaterLevel;
   llSetRegionPos(vTarget);
