Summary

Function: llSetAlpha( float alpha, integer face );
0.0 Forced Delay
10.0 Energy

Sets the alpha on face

• float alpha from 0.0 (clear) to 1.0 (solid) (0.0 <= alpha <= 1.0)
• integer face face number or ALL_SIDES

If face is ALL_SIDES then the function works on all sides.

Caveats

  • The function silently fails if its face value indicates a face that does not exist.

Examples

float cloakSpeed = .1;

default
{
    touch_start(integer total_number)
    {
        integer x;
        float xf;
        for (x=9; x>0; x--)
        {
            xf = x * .1;
            llSleep(cloakSpeed);
            llSetAlpha(xf,ALL_SIDES);      
        }
        state cloaked;
    }
}

state cloaked
{
    touch_start(integer total_number)
    {
        integer x;
        float xf;
        for (x=1; x<11; x++)
        {
            xf = x * .1;
            llSleep(cloakSpeed);
            llSetAlpha(xf,ALL_SIDES);  
        }
        state default;
    }
}
