The term "Alpha" refers to how opaque or transparent an object (or, in this case, a prim) is. In Second Life, the alpha property is set by the scripting functions llSetAlpha, llSetLinkAlpha, llSetPrimitiveParams, and llSetLinkPrimitiveParams. These functions use a float value. When set to 0.0, the object/prim is fully invisible. When set to 1.0, the object is non-transparent. Sometimes, Residents refer to a transparent texture as alpha texture. This is not to be confused with this prim property. See llSetTexture and TEXTURE_TRANSPARENT instead.
Build Mode
In Build Mode, the alpha is represented by a percentage, ranging from 0% to 90%. (Note: The 90% cap is for viewers that have been officially released by Linden Labs)
Examples
Below are examples on how one may set the alpha of an object.
| Function | LSL Example | Description |
|---|---|---|
| llSetAlpha | <lsl>llSetAlpha(1.0, ALL_SIDES);</lsl> | This will set the object's sides' alpha to opaque, or 0%. |
| llSetLinkAlpha | <lsl>llSetLinkAlpha(LINK_SET, 0.0, ALL_SIDES);</lsl> | This will set link-set's alpha to fully transparent, or 100%. (Note: The Viewers released by Linden Labs are unable to set the alpha of an object to fully transparent without a script; the limit is caped at 90%) |
| llSetPrimitiveParams | <lsl>llSetPrimitiveParams([PRIM_COLOR, ALL_SIDES, llGetColor(ALL_SIDES), 0.5]);</lsl> | This will set the object's alpha to translucent, or 50%. |
| llSetLinkPrimitiveParams | <lsl>llSetLinkPrimitiveParams(LINK_SET, [PRIM_COLOR, ALL_SIDES, llGetColor(ALL_SIDES), 0.5]);</lsl> | This will set the link-set's alpha to translucent, or 50%. |
