How would you do this?

I made a barbers pole, the kind with a glass cylinder, and inside there is a striped cylinder that rotates. What I did is:
Made a partially transparent cylinder.
Put the striped cylinder inside it with an llTargetOmega() in a script.
Added details that aren't relevant here.
The problem is that I cannot link them together, because the rotating part would make everything rotate, right? But then it always has to be carefully taken and moved as two unlinked objects, which is a pain.
So, I put the striped pole into the glass part's contents, and then used a script in the glass part to rez the striped part on_rez or on script reset. So I can drop one on the ground, and the pole rezees the striped part which then rotates.
All along, I feel like I am missing some easier way.

Wonder how they do wheels on vehicles, perhaps they are rotating the texture not the prim, I'm no expert, but there seems to be some way to do it.

The prim doesn't need to move al all. Use the AnimSmooth script (in the Library section on waterfalls) to animate the texture to move around the outside of the cylinder.

Ceera, good idea. **whacks** self on forehead.
I'll try Deanna's idea, too.

target omega works separately for linked prims that aren't the root

If your pole texture is a 24bit texture (no alpha channel), take an invisiprim script and drop it in your glass, then set "shiny" on the invisiprim.
"Shiny Glass!"
(warning, it's still an invisiprim! but in this application, you probably won't notice much.)

Which solutions causes less lag? Animated texture or rotating prim?

good question, both are client side effects, texture animation has a few more available options for how it operates, but can't mimic the movement of volume like target omega,... in this case either would work, although target omega might be simpler to write/understand... I can't really guess which runs faster on a client, one manipulates the client prim properties, which at a glance would seem more complex, but the other has more options so presumably uses a similar amount of code to maniulate the textures from within the video memory... depending on your set up it ight run faster one way than the other. neither should add anything to the sim side lag, viewer lag :  hrug::

Both are really actually pretty simple, especially compared to scripts like poseballs, texture changers, menu-driven objects, etc.... compared to those its nothing lol.. even the texture changer would presumably cause more lag.

I would *think* that texture animation would incur less client overhead, since it's just updating the UV coordinates of polys (2D operation), as opposed to updating the vertex locations (3D operation), but I'll side with Okiphia that either would be negligible unless used en masse.
