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.
Caveats
Examples
<lsl>// Get the object to land on the ground or on the water // by Konigmann Lippmann & Strife Onizuka FindGroundOrWater() {
float fHeight = llGround( ZERO_VECTOR );

if( fHeight < fWaterLevel )

vector vTarget = llGetPos();
//llSetPos can only move 10m at a time.
