Now that we know what IDEs are and how they work, how do we use the code provided by Epic? It's there for the taking, but we need an easy way to sift through it. That's where UnCodeX comes in. Let's take a closer look.
UnCodeX is an open source tool which provides an easy interface to browse through the code, analyzes UnrealScript, and is capable of producing a Javadoc like documentation of the source code.
Every good programmer knows their source material. That doesn't mean you need to know the engine inside out, but at least take some time to understand where your most important classes are extending from, and what's available to you. There's no sense in reinventing the wheel if someone has done it for you already, right?
