I want to make a windsock. Is there a consistent direction (and from which) that the wind blows so I can position it effectively?

Thanks!

SL's wind is always changing. It's not all that hard to script yer sock to always face the wind.

Go to the center of the South edge of the RUCE 4 sim. There's a wind sock there, by the bus stop on the North side of the street, that I based it on a freebie US flag and flagpole, that was full-perms.

(EDIT) Oops. Originally posted the one in RUCE 4 was free to copy. Was wrong. Apparently, when that sim got transferred to the new owner, the wind sock became no longer free to copy. I just sent you a copy of "FREE American Flag and Pole" in-world. It has the wind rotator script in it.)

There is a function in LSL called llWind()

Thanks Ceera and Lee.

LOL please disregard my confused IM Ceera.

Lee: is this script like how the linden trees react too?

i believe that the Linden trees have a lot of built in features, including being blown in the wind. But a script using llWind() allows you to sort of simulate those built ins.

Here's a simple script I use for a wind sock. I found it on the scripting tips forum. The -1 in the rotation causes the sock to be rotated correctly to the wind. I also added in the window speed in a remark in case you need it for anything.

CODE

default
{
    state_entry()
    {
        llSetTimerEvent(1);
    }
    
    timer()
    {
        // float wind_speed = llVecMag(llWind(ZERO_VECTOR));
        llSetRot(llRotBetween(<-1,0,0>,llWind(ZERO_VECTOR)));
    }
}
