← Widget API ← UIObject < SetAlpha

Sets the alpha (transparency) of the given object.

MyObject:SetAlpha(alpha)

Arguments

alpha

Number - a floating-point number between 0 and 1: 1 is fully opaque, 0 is transparent (in fact, invisible).

Example

Makes frame MyFrame translucent, more visible than not:

MyFrame:SetAlpha(.75);

Fade the whole UI so that it becomes barely visible:

UIParent:SetAlpha(0.1);

Notes

As of patch 2.1.0, transparency propagates down through all child objects.

"Frame alpha now propagates in the same way as scale (though is clamped between 0 and 1 on each object). This means you can cleanly fade the whole UI or specific frame assemblies."
