| |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.}}
