Movement on attached Multi-prim objects

I have looked through the forums for the answer for this to no avail. I am looking only for someone to point me in the correct direction, because I learn best by working these things out, and learning as I go. I will never be a great scripter.

So, I created an umbrella for a Tiny avatar that opens and closes using llSetPrimitveParams, and it worked beautifully on the ground. Of course, once I attached it to my arm/paw it went crazy.

What can I do to override this, so that my umbrella stays put, but will open and close on touch. I am not at home or I would paste the script in. I can do that later today, if that seems necessary.

Thanks so much.

As I recall there is a defect that requires a nasty hack for this situation (attachments only). It is that a rotation is inverted by the system when it shouldn't be (or vice-versa). Maybe someone who recalls more will chime in. I might be recalling the exact case it affects incorrectly (rotation of attachments, or rotation of child prims of attachments...?). Until then, I'd probably suggest the old alpha changing transparency trick for the prims that move.


I think those are contradictory statements. Don't sell yourself short.

llSetPrimitiveParams() doesn't work in attachments. Use llSetLocalRot() and llSetScale() (for instance) instead.

Check the Wiki. There are instructions on how to handle this. Child prim rotations on attachments are broken, so you basically need to account for the root prim's rotation in all your calculations, or something like that. This used to be in the old Wiki, not sure if all of that made it into the new Wiki.

This is, I believe, what everyone is describing:

llSetLocalRot() == llSetPrimitiveParams([PRIM_ROTATION, <rotation> / llGetRootRotation()]);

Thank you all. As usual, good advice an zero drama.
