Summary
Function: float llWater( vector offset );| 153 | Function ID |
| 0.0 | Forced Delay |
| 10.0 | Energy |
Returns a float that is the water height below 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. Water height is constant across each entire sim and is typically 20 meters but not always.

llSetRegionPos(vTarget);
