a bit complex!!!

ok I have a prim (prin A) and every time it moves I want it to update its position (xyz) in a label above it as it moves.

Also I want another prim (prim B) to rotate so it is always facing prim A

Where do I start???

All suggestions welcome

Thank you

for that you would use a timer and llGetPos() have the timer update the pos after X amount of seconds

kinda like this

MAY NOT BE THE RIGHT THING im alittle tired

update()
{
   llSetText(llGetPos(),<1,1,1>,1);
}
default
{
   state_entry()
   {
      llSetTimerEvent(.1);
   }
   timer()
   {
      update();
   }
}

something like that

I'd start with a timer every X amount of seconds that checks the location (llGetPos), and then changes the llSetText value to reflect the most recent value. I don't believe there is a way to detect moving.. but I'm not certain.

From there, you could have it communicate it's location to the second prim and use llRotLookAt() to make it face the first.

This technically wouldn't be real-time updates, but if you didn't mind the lag from a faster timer it could be pretty accurate, but I'd be careful.

Also, if there is a way to detect movement without a timer or check every X seconds, that would help a lot, I just don't know of one personally.

Well, you should be able to start the timer from a 'moving_start' event handler and stop it from a 'moving_end' handler. You shouldn't need to check periodically outside the context of those events (except maybe for 'on_rez' and such).

Also consider use of llGetObjectDetails() to get the position of an object you want to face point towards.

Sadly, moving_start and moving_end are no longer considered reliable. Storing the "last known" position and then periodically checking if the current position has changed from the last time.. is pretty much the only "reliable" way to know if a prim has moved.

Ah - that's interesting - thanks. I'd encountered this in a door script and wondered why the hell the events weren't getting triggered most of the time. Duly noted.
