Examples

// Get the object to land on the ground or on the water
// 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();
    }
}
