Flagpole\weathervane

How do I get an object (nonphysical and nonflexi) to turn into the wind?

I'd like to make a flag on a pole, but the flexi flag looks stupid when the wind blows 180 degrees in relation to the flag.

use llWind() to determine the direction of wind. Use llSetRot() to set rotation accordingly. Since you want this updated pretty quickly so it looks kinda nice, I suggest using 4 or 5 scripts running in tandem, each running an infinite loop setting the rotation. To make sure they don't all run at the same time, put in a delay before each one starts up.

So, something like this for each script:

default {
	touch_start(integer num_detected) {
		llSleep(0.0); //set the proper delay here
		while (true)
			llSetRot(llEuler2Rot(llWind(<0,0,0>))); //converts the wind vector into a rotation and sets rotation accordingly
	}
}

The above script should rotate the object towards the wind. If you have 4 scripts, set the delays at .00, .05, .10, and .15. That will make it update once every 0.05 secons, which is pretty smooth.

WHile I guess that probably makes sense in theory, in world, the result is something very od. The flagpole falls over, and begins spinning on all three axes. (in jerky little moves)

What I want.. in essence, is a cylander, with an arrow painted on it's top.. to always point directly into the wind, rotating only on it's Z axis..

Dropped one onto you, hope it comes useful. Anyone who needs it just IM me for it. Its a compass with a wind-speed meter. Its based on rotating the texture but can be very easily modified to change the rotation instead by changing the core function of it.

PS: Tanto, Please, don't use While loops in such a Horrible and Nasty manner! It would be wasting Sim resources and slow down everything with a few while loops. The speed is unnecessary for the sake of slowing down everything.

if im not mistaken the script loops quite fine on its own
thus looping it would be redundant
the line

llSetRot(llEuler2Rot(llWind(<0,0,0>))); //converts the wind vector into a rotation and sets rotation accordingly

by its self would acomplish the whole script
seting the rotation to the z axis only and the whole thing fits neatly into 4 lines (counting default and state_entry)
why use more lines than u realy have to?

Zeera's wind compass really did the trick. I had some problems implementing it into a flagpole, and she popped right over to help. We came up with a really cool pole that even puts a wiggle into the flag (so it doesn't look rigid in a strong wind).

If Zeera permits, I'll hapilly post the code for all to use.
