llGetPos and llSetPos

Very basic functions but I am confusing myself yet again I think, lol

What I am trying to do is this.
I have a physical object that moves, when it moves say 5 meters from its spot of rezz I want it to go back to the spot of rezz. I know I need to get the pos on rez to set the home spot but my problem is how do I get it to spring back to the home spot when it goes x meters away from it?

Thanks in advance!!

i don;t think llSetPos works for physical objects, you'll either need to temporarily set it to non-phys, or use llMoveToTarget to move it back the starting position

llSetPos works fine in Physical objects. Post what you have so far and we can point you in the right direction.

Since when?

Er... You sure about that?

edit: fast dragon typing!

Yep, my bad! I was calling physics off first wherever I used it in scripts.

OP, still post whatcha got.

Here is the OP's script:

vector home;
string pos;
float XPOS;
float YPOS;
float ZPOS;
key gQueryID;

default {
	state_entry() {
		gQueryID = (string) home;
		pos = llGetObjectDesc();
	}
	dataserver(key query_id, string data) {
		if (query_id == gQueryID) {
			list tempLine = llParseString2List(data,[","],[]);
			XPOS = llList2Float(tempLine, 0);
			YPOS = llList2Float(tempLine, 1);
			ZPOS = llList2Float(tempLine, 2);
		}
	}
	collision_start(integer num) {
		if (llDetectedName(0) == llGetOwner()) {
			llSetPrimitiveParams([PRIM_PHYSICS, TRUE]);
		}
	}
	collision_end(integer num_detected) {
		pos = llGetObjectDesc();
		llStopSound();
		llSetPrimitiveParams([PRIM_PHYSICS, FALSE]);
		llGetPos();
		llSay(0, (string) XPOS);
		if (XPOS > XPOS + (integer) pos) {
			llSetPrimitiveParams([PRIM_PHANTOM, TRUE]);
			llSetPos(home);
			return;
		}
		if (XPOS < XPOS - (integer) pos) {
			llSetPrimitiveParams([PRIM_PHANTOM, TRUE]);
			llSetPos(home);
			return;
		}
	}
	on_rez(integer start_param) {
		home = llGetPos();
	}
}

Thank you Jesse, I havent been able to post back for some reason untill now

Basically the object will only go physical when the owner touches it. On collision_end I want it to check its pos and if the new pos is greater than home + pos the reset if not then let it be.

The data_server event is never being called:

gQueryID = (string) home;

Is not a valid call. See:

http://lslwiki.net/lslwiki/wakka.php?wakka=dataserver

Calling: pos = llGetObjectDesc();
just once in state_entry works for debugging. Get the script working and then add in extra layers. And on that note, bypass the object description and data_server event entirely and fill in those values manually until you get the script working. Then add in one at a time.

Also remove llStopSound() as it is never called to begin with. Remember that as the others correctly pointed out (and I was delusional) llSetPos will not work with physics. Do you need to jump to position or do you need to move to position? If a hop is fine then bypass the physics. If you need the physics then you need to read up on llMoveToTarget().

And finally one caveat of llSetPos() is a 10 meter max limit. TO go farther, you need to call it in a loop.

Might help if you told us exactly what you were trying to do with this.

BTW the reason you could not post was as I pointed out in world. You have to have a space behind every opening angle bracket to bypass the stupid sql injection attack filter here.

This was the offending bit:

if(XPOS < XPOS - (integer)pos)

Working on doing it a way that doesnt require the dataserver.

The reason for the llStopSound() was that I had originally had a sound on collision start but removed it during my testing. Will post back prob tomorrow night with what I have done.

Thanks again Jesse
