Summary
Function: vector llWind( vector offset );| 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.
Examples
default
{
touch_start(integer num)
{
llSay(0, "Wind velocity: " + (string)llWind(ZERO_VECTOR));
}
}
// wind interpretation as angle and speed
default
{
state_entry()
{
vector windVector = llWind( ZERO_VECTOR);
float windSpeed = llVecMag( windVector);
float windDirection = llAtan2( windVector.y, windVector.x);
integer compassWind = ( 450 - (integer)( RAD_TO_DEG*windDirection))%360;
llOwnerSay( "\nWind direction: "+(string)compassWind+"°\nWind speed: "+(string)windSpeed+" m/S");
}
}
