Summary
Function: llRemoteLoadScriptPin( key target, string name, integer pin, integer running, integer start_param );
| 3.0 | Forced Delay |
| 10.0 | Energy |
Copy script name into target and set to running with a start_param only if target's pin matches pin
| • key | target | – | prim UUID that is in the same region | |
| • string | name | – | a script in the inventory of the prim this script is in | |
| • integer | pin | – | Must match pin set by llSetRemoteScriptAccessPin | |
| • integer | running | – | boolean, if the script is to be set as running. | |
| • integer | start_param | – | value returned by llGetStartParameter in the target script. |
Only works if the script owner can modify target.
Caveats
- This function causes the script to sleep for 3.0 seconds.
- If target is not owned by the same person, and name does not have transfer permissions, an error is shouted on DEBUG_CHANNEL.
- If name permissions do not allow copy, the transfer fails and an error is shouted on DEBUG_CHANNEL.
- If target is not in the same region an error is shouted on DEBUG_CHANNEL.
- When scripts are copied or moved between inventories, their state does not survive the transfer. Memory, event queue and execution position are all discarded.
- If name is missing from the prim's inventory or it is not a script then an error is shouted on DEBUG_CHANNEL.
- If name is present in the target prim's inventory then it is silently replaced.
- start_param only lasts until the script is reset.
- Only the owner of an attachment can modify it while it is being worn.
- If target is an attachment owned by a different user, regardless of object modify rights granted, this function will silently fail.
- If pin fails to match, the error "Task ~Prim~ trying to illegally load script onto task ~Other_Prim~!" is shouted on DEBUG_CHANNEL. "~Prim~" and "~Other_Prim~" are substituted with the applicable prim names.
- If target is the script's parent (
target == llGetKey()) then "Unable to add item!" is shouted on DEBUG_CHANNEL. - If the object containing this script is deeded to a group, than script name needs transfer permissions; even if target is deeded to the same group.
- When the script is set to run (with running, the running checkbox or llSetScriptState) state_entry will be queued.
Examples
Script copier
<lsl>//Copy a script to the second prim integer PIN=1341134;
default {
state_entry() {
llRemoteLoadScriptPin( llGetLinkKey(2), "some script", PIN, TRUE, 0xBEEEEEEF );
}
}</lsl>
Pin setter
Simple script used for setting the pin for a prim, so you can later send scripts to it with llRemoteLoadScriptPin. <lsl>//Child Prim PIN setter integer PIN=1341134;
default {
state_entry() {
llOwnerSay(llGetObjectName()+" : "+(string)llGetKey()+" is ready to accept a describer script using the agreed upon PIN.");
llSetRemoteScriptAccessPin(PIN);
}
}</lsl>
Rez and copy a file from a control object
Notes: There is currently no signing on the starting messages only the owner is checked.
this example rezs a prim from inventory that has a basic control file inside of it and does a basic handshake to setup the pin and transfer the script.
after the transfert the helper script in the rezzed prim deletes itself.
Control prim
<lsl> integer controlchan = 0; integer controlid = -1; start() {
llSetTimerEvent(0);
talkingto = NULL_KEY;
integer a = (integer)llFrand(43);
controlchan = a * a;
controlchan -= controlchan * 3;
controlid = llListen(controlchan,"","","set-connect");
llRezObject("card",llGetPos()+<0,0,0.1>,<0,0,0>,ZERO_ROTATION,a);
llSetTimerEvent(60);
} key talkingto = NULL_KEY; integer busy = FALSE; integer accesspin = 0; default {
timer()
{
llSetTimerEvent(0);
llOwnerSay("Lost connection!");
llListenRemove(controlid);
busy = FALSE;
}
listen(integer chan,string name,key id,string message)

Deep Notes
History
- Added in 1.2.6
- In SL 1.25.4 this function will not copy/move any script into an attachment unless the script is full perm. (SVC-3725)
- SL 1.25.5 will allow this function to copy/move a script into an attachment so long as the target has matching (or more restrictive) copy and transfer permissions. (SVC-3738)
