LSL Portal

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 opaque. 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%.

-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.
