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:SetAlpa(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."
