Factorio Forums

Hi all, I am attempting to learn how to create mods for Factorio. I have followed the modding tutorial on the wiki.
https://wiki.factorio.com/Tutorial:Modd ... al/Gangsir

I have double and triple checked that I have all the files in all the right folders and subfolders in the %appdata%/.factorio/mods folder, yet the mod does not show up in the mod list in game. I even tried editing the mod-list.json file to enable it and factorio just overwrites the file and gets rid of it, I am not quite sure how to proceed with getting the mod to actually be seen by the game. Any and all advice would be appreciated please.

When you start Factorio, the game will check the mods to load. For each mod, the mod version with the highest number will be loaded by default; if the same version is available as zip file and unpacked, the unpacked version will be used.

To find out why your mod isn't loaded, start the game and check factorio-current.log for any messages about loading your mod. If other mods are active, there may be a conflict (perhaps your mod depends on another one that can't be loaded?). In this case, try to disable all other mods and restart again.

The fact that you say your mod entry gets overwritten in the mods-list.json file makes me want to ask/point out the following:

1) You are putting your mod files into a folder/zip file within the mods folder, right? %appdata%/.factorio/mods/<mod_name_here>/
Optional: %appdata%/.factorio/mods/<mod_name_here>_<version>/

2) Double check your info.json file for formatting issues and that the "name" field matches the folder/zip file's name (without version number) and, if you have the version number in the folder/zip file's name, that the "version" field in the info.json file matches this, too.

Otherwise, yeah, as Pi-C wrote, check the log for anything further.

Thank you everyone for the input, I went through and double triple checked my file structure (even including the .zip) and it was correct, finally found the problem. My info.json file was ACTUALLY named info.json.txt and I didn't realize it because I had extensions hidden, fixed that and it works now.
