UPDATE: Never mind, I figured this one out on my own.


Thanks to advice I received in my thread on UnicodeFont, I decided to switch to AngelCodeFont and so far its working great. My problem now is how to do "text wrapping" (without it, my long Strings end up going off the screen).

The Strings are pulled from an external .txt file and stored in an ArrayList<String>, from which they are pulled one line at a time and rendered to the screen. Also, I know the point at which text wrapping needs to be applied (when the width of the String is greater than 770 pixels).

My question is how to implement text wrapping under these conditions.

The code in question is shown below (this is not the entire class...),
