Summary

Function: llSetHoverHeight( float height, integer water, float tau );
123 Function ID
0.0 Delay
10.0 Energy

Critically damps to a height above the ground (or water) in tau seconds.

• float height – Distance above the ground
• integer water – boolean, if TRUE then hover above water too.
• float tau – seconds to critically damps in

Do not use with vehicles.
Use llStopHover to stop hovering.

Caveats

  • Only works in physics-enabled objects.
  • Do not rely on built-in limits. In the past, the difference between the object's initial position and the hover height was limited to 64 meters. Under SL Server 1.26.2 the limit is 4096 meters above the ground level.

Examples

 
// Put in an attached prim and touch to start floating in air without flying.
// Touch again to drop to the ground.
 
integer gHovering = FALSE; // are we supposd to be hovering now?
 
default {
    touch_start(integer total_number) {
        if (!llGetAttached()) {
            llWhisper(0, "Wear me to play.");
            return;
        }
 
        if (gHovering) {
            llOwnerSay("Releasing you.");
            llStopHover();
        }
        else {
            llOwnerSay("Making you float...");
 
            // Start hovering 5 meters over our current location.
            vector myPosition = llGetPos();
            llSetHoverHeight(myPosition.z - llGround(ZERO_VECTOR) + 5.0, FALSE, 1.0);
        }
 
        gHovering = !gHovering; // flip the switch
    }
}
