why doesn't this work?

ok i'm trying to make an air lock like thing, and I need a extending arm, how the issue is that i can't make it move with llSetPos, the arm thing is a cylinder, I have even copied and pasted it into another prim in the object and it moves just fine, so why doesn't it work?

is there an issue with a cylinder and llSetPos

default
{
link_message(integer num,integer set, string message, key id)
{
if (message == "open"
{
llSetPos(<0,5,-2>;
}
if (message == "close"
{
llSetPos(<0,.5,-2>;
}
}

}

that's the script that's in it right now

llSetPos can't move the object more than 10 meters at a time.

In a child prim, the vectors are relative to the root prim, so the vector is well within reach of that limit, but it's far less likely that those vectors are close to the position of your root prim in the sim.

Especially considering the negative Z coordinate.

i feel like an idiot now

the script isn't running

i didn't touch it it must of just happend

aslo I'm doing the move on a child prim, and you can move objects more then 10m in a set, but you can't move the thing sim wise more then 10m at a time
