I've started a code repository so that anyone can use my source code to write their own programs to interface with the Turok formats if they wish. The repository is https://github.com/mdecicco/T4Loader and I also put a link in the original post.

Currently it's pretty limited since I started writing it all over again, but give me about a week and it'll be able to open/save all actor data and all level data. Once I'm done with that I'm going to do a quick rewrite of the actual editor I've been working on using the new code I'm writing now. It might be kind of buggy at first but I want to get something out as fast as possible that you can all use and experiment with.

There is something that I need some help with though. I've learned that there are about a thousand different types of variables that can be modified in the actor files... I do not expect to learn how to use all of these but I plan on making a hierarchical data editor that will allow us to modify any actor variable and any other data in the files, even if we don't know what it is. Using this we can mess with one thing at a time to see how it affects the game. Then maybe we can make a new thread and post our findings so that I can make the editor use the data better.
