Summary

Function: llSetBuoyancy( float buoyancy );
0.0 Forced Delay
10.0 Energy

Sets the buoyancy of the task or object. Requires physics to be enabled.

• float buoyancy

if (buoyancy == 0.0) disables
if (buoyancy < 1.0) sinks
if (buoyancy == 1.0) floats
if (buoyancy > 1.0) rises

Caveats

  • Wind can cause the prim to drift.
  • Unlike some other characteristics, this is cancelled if the script that set buoyancy is removed from the prim.
  • This function eats energy to keep the object floating. Large objects may not be able to supply enough energy to keep the object floating.

Examples

Makes an object float up slowly (e.g. a red balloon)<lsl>default {

   state_entry()
   {
       llSetStatus(STATUS_PHYSICS, TRUE);
       llSetBuoyancy(1.05);
   }
}</lsl>

Notes

Often used to make an object look like gravity does not affect it.
