Summary
Function: vector llWind( vector offset );| 44 | Function ID |
| 0.0 | Forced Delay |
| 10.0 | Energy |
Returns a vector that is the wind velocity at the prim's position + offset
| • vector | offset | – | offset relative to the prim's position and expressed in local coordinates |
The requested position needs to be in the same region. Only the x and y coordinates in offset are important, the z component is ignored.
