Chapter 26 ■ Creating Unit Frames with Group Templates 521Figure 26-6 shows the unit frames with a dead unit, which is much easier tosee when it’s shaded.Figure 26-6: SquareUnitFrames showing a dead unit shaded outDisplaying Unit NamesCurrently, whenever SquareUnitFrames displays a name that is longer thanfour characters (and some names that are shorter), it is truncated with anellipsis (‘‘ ... ’’) at the end. This isn’t very desirable—an ellipsis takes upmuch of the unit button’s width, space that could be better used to displaymore characters of the name—but WoW doesn’t really provide an easy wayto fit as much of a name as possible in a font string of limited width.What you can do instead is try different substrings of the name in order tofit as many characters as you can in a 30-pixel-wide font string. This algorithmmight look like this:local substring(name, length)for length=#name, 1, -1 dosubstring = string.sub(name, 1, length)button.name:SetText(substring)if button.name:GetStringWidth() print(string.len(“Grüber“))7
