Is is possible to populate a textfield that is on a arc, arched, or half circle? If so how is the best way to do it while keeping the text centered. It's not worth it if I have to make seperate text fields for each letter.
No, not as far as I know. You can rotate the textfield, but it will remain linear at the selected angle. Individual textfields would work, but it will be incredibly messy. If the text is static (eg not changing at runtime) then you could import it as an image from Illustrator or Photoshop.
