One Script, many doors
This script is my attempt at solving the massive amount of simple door scripts one can have in a sim (I removed about 110 door scripts in my sim using this system)
It handles clockwise and counter clockwise door direction, a name based access control list, play sounds, and the root prim reports memory free (useful for REALLY big door sets).
HOW TO USE IT
All your doors have to be one prim, typical cube with a path cut of 0.125 0.625 .
- All your doors must be linked to a root prim which won't be a door.
- All the doors must be uniquely named.
- All the doors must have "left" or "right" in their description depending on the direction you want them to swing to.
- In the root prim you will need 3 rezzable objects (simple cubes will do) named "open" , "close" and "lock" with, in them, the corresponding scripts (see at the bottom of the page) in order to play sounds at the right place.
- You need a configuration notecard called "config"
main door script: must be in the root prim of the door link set. <lsl> /******************************************* Single script, linked, lockable, door system by Kyrah Abattoir

Sound emitter script
You need this script in the 3 rezzable objects "open" "close" and "lock" in order to play your door sounds at the right place (At the time i wrote this , lsl doesn't allow yet to play sounds from an unscripted prim in a link set)
<lsl> string sound_to_play = "my door sound";// put your sound name/key here
//This functions is from Nomad Padar, pretty awesome! //decode from integer to vector vector int2vec(integer n) {
//0zyx ZZZZ ZZZZ ZZZZ YYYY YYYY XXXX XXXX return <n&0xFF, (n>>8)&0xFF, ((n>>16)&0xFF)> + <((n&0x10000000)!=0)*.5,((n&0x20000000)!=0)*.5,((n&0x40000000)!=0)*.5>;
}
default {
state_entry()
{
llSetStatus(STATUS_PHANTOM, TRUE);
llSetPrimitiveParams([PRIM_TEMP_ON_REZ, TRUE]);
llSetTexture(TEXTURE_TRANSPARENT,ALL_SIDES);
}
on_rez(integer a)
{
if(a == 0)
return;
vector destination = int2vec(a);
integer i;
for(i=0 ; i<50 && (llGetPos() != destination) ; i++)
llSetPos(destination);
if(llGetPos() == destination)
llTriggerSound(sound_to_play,1.0);
llDie();
}
} </lsl> Example "config" notecard:
//lines starting with "//" are ignored //Syntax: one line per door in the format door_name=user name,user name My fancy front door=Kyrah Abattoir My secret playroom door=Kyrah Abattoir,Timeless Prototype //of course if you want to lock a door from anybody you can set it to something like this: Mine entrance=condemned until further notice
