Target Child Prim of Rezzed Object

[Ruthven Ravenhurst]

So the object_rez get's the key of the root prim of the object being rezzed, but I'm wondering how I can get the key of a child prim of the object without using a listen event. I want to target it with particles, but with the root prim using llTargetOmega so that it makes the child prim orbit it. My theory is that when the object rezzes, I can set the root prim's description with the key of the link I intend to target using llGetLinkKey, and then in the rezzing script, in the object_rez event use llGetObjectDetails to get the object's description. Which is faster? The llSetObjectDescription(llGetLinkKey)), or llGetObjectDetails(id, [OBJECT_DESC]);? I want to make sure the description is set with the key before llGetObjectDetails tries to capture it for the particle target. I guess I could use llSleep. Can anyone suggest another way other than a listen or sensor (will the sensor even pick up a child prim?)

I know one and only one way to get a child prim's UUID without (chat) communication
That is by llCastRay
It won't even work if the child prim has physics shape type set to None

Keep searching

You can not depend on timing in SL. Things can get delayed by seconds. Just poll llGetObjectDetails in a loop. Don't forget to set an upper limit and break off if things get stuck.

Why not a listen? It's certainly much more efficient than any alternative suggested so far.
