I’m trying to put this in Codea but I’m lost as what to do? Trying to make a doom like game in Codea.

At the bottom of the link you show, there is another link to the code on getHub. In grtHub, you have to copy each file, (select RAW first), and then paste the code into a Codea project. Whether it will run or not without changes in Codea, I don’t know. You’ll find that out once you try to run it.
