Summary

Function: float llWater( vector offset );

Returns a float that is the water height below the prim's 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. Water height is constant across each entire sim and is typically 20 meters but not always.

Examples

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

FindGroundOrWater() {

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

}

default {

   touch_start(integer total_number)
   {
       FindGroundOrWater();
   }

}

</lsl>
