My code is based off of the tutorial created by NeHe (http://lwjgl.org/wiki/index.php?title=Slick-Util_Library_-Part_3-_TrueType_Fonts_for_LWJGL), and it works when I tested it out as exactly shown on the website, but when I tried to integrate it into my game engine, it no longer works.

Ignore please, I fixed it myself. Problem was due to lack of clean code. Rewrote everything. Its good.
