Description
Constant: integer PRIM_POINT_LIGHT = 23;The integer constant PRIM_POINT_LIGHT has the value 23
PRIM_POINT_LIGHT is used to configure the point light configuration of the prim
llSetPrimitiveParams
[ PRIM_POINT_LIGHT, integer boolean, vector color, float intensity, float radius, float falloff ]| • integer | boolean | – | TRUE enables, FALSE disables | |
| • vector | color | – | color in RGB <R, G, B> (<0.0, 0.0, 0.0> = black, <1.0, 1.0, 1.0> = white) | |
| • float | intensity | – | ranges from 0.0 to 1.0 | |
| • float | radius | – | ranges from 0.1 to 10.0 | |
| • float | falloff | – | ranges from 0.01 to 1.0 |
When used with llSetPrimitiveParams & llSetLinkPrimitiveParams
llGetPrimitiveParams
llGetPrimitiveParams([ PRIM_POINT_LIGHT ]);Returns the list [ integer boolean, vector color, float intensity, float radius, float falloff ]
| • integer | boolean | – | TRUE enables, FALSE disables | |
| • vector | color | – | color in RGB <R, G, B> (<0.0, 0.0, 0.0> = black, <1.0, 1.0, 1.0> = white) | |
| • float | intensity | – | ranges from 0.0 to 1.0 | |
| • float | radius | – | ranges from 0.1 to 10.0 | |
| • float | falloff | – | ranges from 0.01 to 1.0 |

Examples
<lsl> // simple light source demonstrator // 8feb07 "tetsumo kuri" // thanks to squee janitor for line to dissect
integer light_s = TRUE; // "_s" for status
default {
state_entry()
{
// llSetText("click me",<1,0,0.6>,.5); // in case you like labels
}
touch_start(integer total_number)
{
if ( light_s )
{
light_s = FALSE;
// fullbright doesn't have anything to do with light in NEW(2006?) lighting model
// setting fullbright does look good though
llSetPrimitiveParams([PRIM_FULLBRIGHT,ALL_SIDES,FALSE]);
llSetPrimitiveParams([PRIM_POINT_LIGHT, FALSE, // if this is false, light is off,
<0.0,1.0,0.0>,1.0, 10.0, 0.5]); // rest of params don't matter
}
else
{
light_s = TRUE;
//llSetPrimitiveParams([PRIM_FULLBRIGHT,ALL_SIDES,TRUE]); //leave fullbright commented for now
llSetPrimitiveParams([PRIM_POINT_LIGHT,TRUE,
<1.0,0.7,1.0>, // light color vector range: 0.0-1.0 *3
1.0, // intensity (0.0-1.0)
10.0, // radius (.1-10.0)
0.6 ]); // falloff (.01-1.0)
// this could have been done in one line, like this
//llSetPrimitiveParams([PRIM_FULLBRIGHT,ALL_SIDES,FALSE,PRIM_POINT_LIGHT,TRUE,<1.0,1.0,0.5>,20,1.0,0.5]);
// ... but thats kinda hard to take in...
}
//llSay(0, " Click!");
