SetHoverHeight

llSetHoverHeight

Summary

Function: llSetHoverHeight( float height, integer water, float tau );

123	Function ID
0.0	Forced 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 damp 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 there is no apparent limit.

Examples

<lsl> // 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
   }

}

</lsl>
