"Custom Types Editor" Is unavailable

Very new to Tiled, though I have been tinkering with it for a few hours straight so I know most of the basics in terms of navigation and such. I’m not new to game design, however. I’m trying to mod a game, and it uses several custom properties to adjust how it looks. It’s official guide calls for [View → Custom Types Editor] to be enabled, but it’s grayed out.


So far I’ve looked at this question and it seems my issue is something to do with not having a project open since that’s what Custom Properties use. However, I’m not sure what that’s describing- again, new and all.

For context, I’m using Tiled to mod a Steam game: Carrion. The developers released a Steam Workshop addon that gave a tutorial on what is required to mod the game years ago. After creating a starter level through it’s toolkit, a .json is given that includes all the templates it uses. Everything is as the tutorial describes up until that “Custom Types Editor”. I say all this because there’s a possibility that I was meant to make a project before anything I’ve done already.

Long explanation short:
How do projects work? What do I need open?

Thank you to those who so much as read all of this.

You have to have a Tiled Project loaded for custom types to be available, as they are stored in the Project file. You can create a new Project in File > New > New Project. This will create a file that keeps track of your maps, tilesets, settings, etc for this particular project. When you load a Project, it’ll open all the files you had open for that project before and apply the relevant settings, and let you use the custom types defined for that project.

The tutorial might just be very old, as it used to be that custom types were stored in a shared global file rather than in a project.

Perfect! Yes, the tutorial is likely several years old at this point.

Thank you so much
