Summary
Function: llSetBuoyancy( float buoyancy );| 122 | Function ID |
| 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. (server 1.38.4 this appears not to be true)
- 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.
