Modding tutorial

[Skimsh]

Is there any link or video tutorials for modding for AoE4 editor, I know there is on official aoe YT channel. I'm asking if there is one for like more elaborate explanation for each function.

I tested and published my first mod today. I didn't read the documentation or watch videos.
I did it through agentic AI with OpenAI's Codex ($20/mo). I gave it the official documentation, some example mods with similar functionality, and project guidance. It was able to navigate through the Content Editor, stumbling around a lot at first, but documenting what it learned each session. It was taking its own screenshots as needed too.

My first attempt was just to copy some assets and then change the values through scripting, but this failed because the XML from automated scripting was not exactly the same as the XML produced by the Content Editor. It ran into problems trying to change the values while the Content Editor was open (edits saved on disk did not match what was saved in memory). So we revised the plan to make all of the copies in the Content Editor first, then script the changes offline and verify them. After that, we went back to the Content Editor to do the final build. Then it showed up in the game as a local mod, and I was able to publish from there and play with a friend.

The process took about 30 hours. It discovered dozens of problems with its methods of scripting and navigating the Content Editor's GUI, but the last several hours went by much cleaner and faster as it updated its own documentation and improved its own methods. If you watch and guide the self learning process and read through the reasoning model's output at each step, and compare with what you're seeing on the screen in the Content Editor, you can learn quite a lot. Maybe that's not for everyone, but I had fun with the project.
