|spec
|caveats=*Applying an operation to [[LINK_SET]] is applied first to the root prim, then to each child prim.
*[[llGetLinkPrimitiveParams]] can be used to get corresponding parameters from linked prims.
* [[PRIM_LINK_TARGET]] is a special paramter which can be inserted to perfom actions on multiple prims on the linkset with one call.
* [[PRIM_ROTATION]] is bugged in child prims, use [[PRIM_ROT_LOCAL]] instead or see [[llSetLinkPrimitiveParams#Useful_Snippets|Useful Snippets]] for a workaround, or the linked SVC-93 issue below.
* '''Some prim properties are reset''' by this function
** A flexible prim will become not flexible
** A sliced prim will become unsliced
: In order to preserve properties they must be saved and explicitly set in the function call
{{LSL Tip|This function has a delay of 0.2 seconds per call. Please consider using [[llSetLinkPrimitiveParamsFast]] instead. You can do exactly the same that way, just without the delay.}}
{{LSL Tip|When wanting to change the alpha value of a face, please consider using [[llSetLinkAlpha]](integer link, float alpha, integer face); instead of [[llSetLinkPrimitiveParams]](integer link, [ [[PRIM_COLOR]], integer face, vector color, float alpha ]);, that way you don't have to mess with the color settings and don't get a 0.2 seconds delay per call.}}
|constants={{LSL Constants/PrimitiveParams|set|remote=true}}
|examples =
A simple script to light up a prim in a [[linkset]] when touched, and unlight the others using llSetLinkPrimitiveParams, when script is installed in the root prim of the linkset.
<lsl>
default
{
    touch_start(integer total_number)
    {
        // Turn off all prims
        llSetLinkPrimitiveParams(LINK_SET,[PRIM_FULLBRIGHT,ALL_SIDES,FALSE]);
        // Turn on the one that was touched
        llSetLinkPrimitiveParams(llDetectedLinkNumber(0),[PRIM_FULLBRIGHT,ALL_SIDES,TRUE]);       
    }
}
</lsl>
{{LSL Tip|You can use one function call instead of two when making use of [[PRIM_LINK_TARGET]]. Do pay attention though that [[llSetLinkPrimitiveParams]] still does have a 0.2 seconds delay per function call, while [[llSetLinkPrimitiveParamsFast]] does not.}}
