Summary
Function: llSetAlpha( float alpha, integer face );51 | Function ID |
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
<lsl> 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; }
}
</lsl>Notes
In practical terms, "alpha" means "transparency" or "visibility".
To be clear, llSetAlpha will only affect the prim that the script it is in. It will not affect any linked prims. To set the alpha state for those, use llSetLinkAlpha
