Produces an simple tracking/letter-spacing effect on UI Text components. Produces an simple mono-spacing effect on UI Text components.
Set the spacing parameter to adjust letter spacing. Set the spacing parameter to adjust mono spacing.
Negative values cuddle the text up tighter than normal. Go too far and it'll look odd. Negative values cuddle the text up tighter than normal. Go too far and it'll look odd.
Positive values spread the text out more than normal. This will NOT respect the text area you've defined. Positive values spread the text out more than normal. This will NOT respect the text area you've defined.
Zero spacing will present the font with no changes. Zero spacing will present the font with no changes.
