What’s in a Project
A Tiled project file primarily defines the list of folders containing the assets belonging to that project. In addition, it provides an anchor for the session file.
Apart from the list of folders, a project currently has the following properties, which can be changed through the Project -> Project Properties… dialog.
- Compatibility Version
The Tiled version to target when saving or exporting files. Can be used to maintain compatibility with earlier versions of Tiled or with Libraries and Frameworks that do not yet support certain backwards-incompatible changes.
- Extensions Directory
A project-specific directory where you can put Tiled extensions. It defaults to simply
extensions, so when you have a directory called “extensions” alongside your project file it will be picked up automatically.
The directory is loaded in addition to the global extensions.
- Automapping Rules File
Refers to an Automapping rules file, or a single rule map, that should be used for all maps while this project is loaded. It is ignored for maps that have a
rules.txtfile saved alongside them.
Any types defined in the Custom Types Editor are also saved in the project.
Each project file gets an associated .tiled-session file, stored alongside it. The session file should generally not be shared with others and stores your last opened files, part of their last editor state, last used parameters in dialogs, etc.
When switching projects Tiled automatically switches to the associated session, so you can easily resume where you left off. When no project is loaded a global session file is used.
Opening a File in the Project
Another advantage of setting up a project is that you can quickly open any
file with a recognized extension located in one of the folders of the project.
Use File -> Open File in Project (
Ctrl+P) to open the file filter and
just type the name of the file you’d like to open.
