PRIM_POINT_LIGHT question & Script help please!

Hi, I'm trying to write a script for a glowing orb on the top a of staff. What I'm trying to do is detect the colour of the orb(the staff already has a working colour change script for the orb) and then set a soft light based on the colour of it. I know roughly how to detect the colour of a prim, but can't seem to work out how to pass a vector into the llSetLinkPrimitiveParams.

Is it possible to use something like (LINK_THIS,[PRIM_POINT_LIGHT,TRUE,(vector)detected_colour,1,2,0.5]); ??

I just need a script that will work in the link the script is inside (as is a 50 prim linked set with multiple pieces/colours) that detects that links color (1 sided sphere) and then based on that sets a soft pin point light. If poss a way to also update the light when the colour is changed via another script (possibly use linked message to llResetScript?)


Thanks in advance

If, as I understand it, there are multiple scripts that may be changing the orb's color, probably the least painful approach would be to embed a script inside the orb prim that does something like:

default
{
    changed(integer change)
    {
        if (change & CHANGED_COLOR)
        {
            vector detectedColor = llGetColor(0);
            llSetPrimitiveParams([PRIM_POINT_LIGHT, TRUE, detectedColor, 1, 2, 0.5]);
        }
    }
}

EDIT: meh post lag, Qie got it first... and better

if the user is coloring the globe manually you'll need a script in the globe to pick up the current color... something like

 llSetPrimitiveParams( [PRIM_POINT_LIGHT, TRUE, llGetColor( ALL_SIDES ), vFltIntensity, vFltRadius, vFltFalloff] );
 

if you already know the color (because you set it w/ the script) you can use llSetLinkPrimitiveParams and just have the color you used saved as a variable of type vector (saves conversion)

alternately you could ignore it's actual color, set fullbright and make the light white regardless....

Thanks Qie & Void..i knew it wasn't difficult works perfect thankyou!
