# PRIM GLOW

 LSL Portal

## Contents

Constant: integer PRIM_GLOW = 25;

The integer constant PRIM_GLOW has the value 25

PRIM_GLOW is used to get or set the glow status of the face. Use the integer number 25 if the compiler rejects the named constant.

[ PRIM_GLOW, integer face, float intensity ]
 • integer face – face number or ALL_SIDES • float intensity – ranges from 0.0 to 1.0

When used with llSetPrimitiveParams & llSetLinkPrimitiveParams

llGetPrimitiveParams([ PRIM_GLOW, integer face ]);

Returns the list [ float intensity ]

 • integer face – face number or ALL_SIDES • float intensity – ranges from 0.0 to 1.0

#### Caveats

• If face is ALL_SIDES then the PRIM_GLOW works on all sides.
• If face indicates a face that does not exist the PRIM_GLOW return is [ 0.0 ]

## Examples

basic syntax to set glow

```// adjust as desired .3 to a float number from 0 to 1.0 inclusive
// adjust as desired ALL_SIDES to specific prim faces if desired

llSetPrimitiveParams( [ PRIM_GLOW, ALL_SIDES, .3 ] ) ;```

basic syntax to get glow status

```list mylist = llGetPrimitiveParams([ PRIM_GLOW,ALL_SIDES] );
llSay(0, llList2CSV(mylist));

//Assuming for this example that all sides are set to the same float of .3
//In a box, which has 6 sides, the above example returns 0.300000, 0.300000, 0.300000, 0.300000, 0.300000, 0.300000
//In a prism, which has 5 sides, returns 0.300000, 0.300000, 0.300000, 0.300000, 0.300000
//In a sphere, which has only 1 side (as it were), returns 0.300000
//change ALL_SIDES to a specific prim face if desired.```

```//Each time the prim is touched, the intensity of the glow is increased (until it maxes out and cycles back to zero).
integer steps = 10;
integer counter = 0;

default
{
touch_start(integer total_number)
{
llSetPrimitiveParams( [ PRIM_GLOW, ALL_SIDES,  counter / (steps - 1.0) ]);
counter = (counter + 1) % steps;
}
}```
```//Each time the prim is touched, the intensity of the glow is decreased (until it hits zero and cycles back to one).
integer steps = 10;
integer counter = 0;

default
{

touch_start(integer total_number)
{
llSetPrimitiveParams( [ PRIM_GLOW, ALL_SIDES,  counter / (steps - 1.0) ]);
counter = (counter + steps - 1) % steps;
}

}```
