Summary
Function: llSetColor( vector color, integer face );| 0.0 | Forced Delay |
| 10.0 | Energy |
Sets the Blinn-Phong color on face of the prim.
| • vector | color | – | color in RGB <R, G, B> (<0.0, 0.0, 0.0> = black, <1.0, 1.0, 1.0> = white) | |
| • integer | face | – | face number or ALL_SIDES |
If face is ALL_SIDES then the function works on all sides.
Newbie Notes
llSetColor changes the color of a prim, either on a specific side (face) or the entire prim.
Example:llSetColor(<r, g, b>, ALL_SIDES);
r, g, b: values for red, green, blue ranging from <0.0, 0.0, 0.0> (black) to <1.0, 1.0, 1.0> (white)
To continue reading see: Newbie Notes
Caveats
- The function silently fails if its face value indicates a face that does not exist.
- llSetColor will have no visible effect on faces with a PBR material. To work on faces both with and without a PBR material, use this snippet:
llSetColor(color, ALL_SIDES); llSetLinkPrimitiveParamsFast(LINK_THIS, [PRIM_GLTF_BASE_COLOR, ALL_SIDES, "", "", "", "", llsRGB2Linear(color), "", "", "", ""]);
Examples
integer face = -1;
vector color = <1.0, 1.0, 1.0>;
default
{
touch_start(integer num)
{
if(~face) //quick & dirty but efficient way of testing if face is not equal to -1
llSetColor(color, face); //restore the color
face = (face + 1) % llGetNumberOfSides(); //increment and keep the face number in range
color = llGetColor(face); //save the face's color
llSetColor(<0.5, 0.0, 0.0>, face ); //change the face's color
}
}
