I am considering for a personal project having more than 999 maps.
So far I have searched around for various solutions and found a few. One is plugins that allow for folders of maps that were made in separate projects, and calling them in the main project. But I wanted to be able to edit the additional maps in the editor for control and organization without hassle.
Notably, on a test project, I tried coping Map001.json, renaming it Map1000.json and adding an entry for Map 1000 in the MapInfos.json
This seemed to work! It appeared in the editor and was editable. Adding an event on Map 1 transfer to the map 1000 and playtesting that went well. Though one thing is, the map is not labelled as 1000 in the editor. It is labelled as Map 2, as if I had added the new map in the editor. This makes me wonder if once reaching the point of 999 maps and adding another one, this method wouldn't actually work? (as in, I wonder if the 1000th map would show up in the editor if there were already 999)
It's not a big deal to me to resolve this quickly, but I'm very interested. Thank you for reading.
