Summary

Function: float llGround( vector offset );

Returns a float that is the ground height directly below the prim plus an offset

• vector offset

The requested position needs to be in the same sim, only the X & Y of the offset are important.

Examples

<lsl>// by Konigmann Lippmann & Strife Onizuka FindGroundOrWater() {

   float fHeight = llGround( ZERO_VECTOR );
   float fWaterLevel = llWater( ZERO_VECTOR );
   if( fHeight < fWaterLevel )
       fHeight = fWaterLevel;
   vector vTarget = llGetPos();
   //llSetPos can only move 10m at a time.
   integer iCounter = 1 + llAbs((integer)(vTarget.z - fHeight) / 10);
   vTarget.z = fHeight;
   do
       llSetPos( vTarget );
   while( --iCounter );

}

default {

   touch_start(integer total_number)
   {
       FindGroundOrWater();
   }
}</lsl>
