Is it Possible??

I built a large avatar with wings constructed from Four 10m prim cubes, then linked to the one prim nearest the body. The body itself is quite large.

So- is it possible to script the wings to flap, either as actual flapping or would the whole "changing alpha on an Up wing/Down wing" work and stay synchronzied.

The alpha/non alpha solution is the easiest, but imho it looks bad on something like this. It's great for something like a holstered weapon vs drawn weapon, but a wing should have movement.

I don't make wings, but the easiest thing to do I would imagine would be to first, unlink the wings from the main AV and have them as separate attachments.

I believe if you have a sphere as the root prim at the base of the wing and rotate that back and forth it will create the flapping motion quite easily, but I cannot say for sure since I'm used to limiting the amount of prims I have to move on an object.

it would work, you could just use multiple scripts, and have a main script control them all with link messages. example pseudo code.
in the wings-
link_message
flap(num);

where flap is a global function that checks if integer flap is == true, if it is set the rotation to outwards. if its false (!flap) set the rotation to inwards.

main script
timer()
flap = !flap
llmessagelinked(flap) or whatever.

tadaa, that's how it would work.
