UnCodeX is a combination of UClasses and UnDox created by El Muerte TDS.

UnCodeX can create a class and package tree from the UnrealScript sources, analyse the content of each class for later use.

UnCodeX also gives you the ability to create a high detailed HTML API reference from your code. It includes all definitions made in classes, syntax highlighted source code, links to the type declarations, automatic JavaDoc-like documentation from your source code and much more.

You can take a look at the following examples:

Note: UnCodeX should work with the source code of all games based on any of the Unreal Engine Versions.

Please report bugs/feature requests to: elmuerte@drunksnipers.com or add them to this page.
