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

// 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();
    }
}
