Retaining values?

Hello, I am working on a simple light, dialog controlled, with multiple choices for light color, intensity(dimmer), ect. My question is, how to get the light to retain the color vector selected while also selecting an intensity setting.
Is there a way for the script to check what color is being used, and dim or brighten it as well?

I might be in over my head, but enjoy the challenge, please point me in the right direction so to speak.

Global Variables?

If you're looking to fade a color from very colorful to very pale...you would also need to shift color as you shift intensity. You would do so by shifting all relevant vector values by a set amount.

BUt yes...global variables will hold a value throughout a script if that's all you're looking for.

Are you speaking of point ("real" or GL) lights ? If so:

CODE


// PointLight Params : [ON_OFF, color, intensity, radius, falloff]

setLightOn (integer on) {
    list lightParams;
    lightParams = llGetPrimitiveParams([PRIM_POINT_LIGHT]);
    lightParams = llListReplaceList(lightParams, [on], 0,0);
    llSetPrimitiveParams([PRIM_POINT_LIGHT] + lightParams);
}

setLightColor (vector color) {
    list lightParams;
    lightParams = llGetPrimitiveParams([PRIM_POINT_LIGHT]);
    lightParams = llListReplaceList(lightParams, [color], 1,1);
    llSetPrimitiveParams([PRIM_POINT_LIGHT] + lightParams);
}

setLightLevel (float level) {
    list lightParams;
    lightParams = llGetPrimitiveParams([PRIM_POINT_LIGHT]);
    lightParams = llListReplaceList(lightParams, [level], 2,2);
    llSetPrimitiveParams([PRIM_POINT_LIGHT] + lightParams);
}

I think the orignal question was pertaining to selecting the data from the user dialogs and retaining the first selection while awaiting the second.
