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.

Example

MyFrame:SetAlpha(.75); 

Makes the frame translucent, more visible than not.

Notes

Transparency is applied to child objects the same as scaling. If a parent is set to e.g 0.5, and a child is set to 1, the child will still be shown as 0.5. If a parent and child both are set to 0.5, the result will be 0.5 * 0.5 = 0.25 for the child.

If you attempt to set the same value more than once it will detect this and return early after the first attempt.
