LSL rotate script: smooth spinning object

A spinning sign or turning product stand catches the eye. This rotate script uses smooth client-side rotation: each viewer draws the spin itself, so it looks fluid and puts almost no load on the region.

How to set it up

Put the script in the object you want to spin and save. It starts turning right away.
Change SPIN_AXIS if it turns the wrong way round, and SPIN_SPEED to make it faster or slower.
With TOUCH_TOGGLE on, touch the object to stop or start it.

Settings

SPIN_AXIS: the axis to turn around. <0,0,1> turns like a turntable, <1,0,0> rolls like a wheel, <0,1,0> flips forwards.
SPIN_SPEED: radians per second. 0.5 is a calm turn, 3.0 is fast. Negative numbers turn the other way.
TOUCH_TOGGLE: TRUE lets visitors stop and start the spin by touching it.

Tips

In a linked object, put the script in a child prim to spin only that part, such as fan blades or a wheel.
Because each viewer draws the spin, different people can see the object at a slightly different angle. That is normal.

Frequently asked questions

Why does the object jump back when I edit it?

Smooth rotation is only drawn by viewers; the object's real rotation does not change. When you edit it, you see its real rotation.

How do I stop the spin for good?

Set SPIN_SPEED to 0.0 and save, or touch it with TOUCH_TOGGLE on, then delete the script.

Does it work on physical objects?

This script is meant for normal, non-physical objects such as signs and decorations.
