Originally, Godot did not have any means to export projects. The developers would compile the proper binaries and build the packages for each platform manually.
When more developers (and even non-programmers) started using it, and when our company started taking more projects at the same time, it became evident that this was a bottleneck.
Distributing a game project on PC with Godot is rather easy. Drop
the Godot binary in the same directory as the
then compress the project directory and you are done.
It sounds simple, but there are probably a few reasons why the developer may not want to do this. The first one is that it may not be desirable to distribute loads of files. Some developers may not like curious users peeking at how the game was made, others may find it inelegant, and so on. Another reason is that the developer might prefer a specially-compiled binary, which is smaller in size, more optimized and does not include tools like the editor and debugger.
Finally, Godot has a simple but efficient system for creating DLCs as extra package files.
The same scenario on mobile platforms is a little worse. To distribute a project on those devices, a binary for each of those platforms is built, then added to a native project together with the game data.
This can be troublesome because it means that the developer must be familiarized with the SDK of each platform before even being able to export. While learning each SDK is always encouraged, it can be frustrating to be forced to do it at an undesired time.
There is also another problem with this approach: different devices prefer some data in different formats to run. The main example of this is texture compression. All PC hardware uses S3TC (BC) compression and that has been standardized for more than a decade, but mobile devices use different formats for texture compression, such as PVRTC (iOS) or ETC (Android).
Exporting from the command line¶
In production, it is useful to automate builds, and Godot supports this
--export-debug command line parameters.
Exporting from the command line still requires an export preset to define
the export parameters. A basic invocation of the command would be:
godot --export "Windows Desktop" some_name
This will export to
some_name.exe, assuming there is a preset
called "Windows Desktop" and the template can be found.
The output path is relative to the project path or absolute;
it does not respect the directory the command was invoked from.
You can also configure it to export only the PCK or ZIP file, allowing
a single export to be used with multiple Godot executables.
This takes place if the target name ends with
It is often useful to combine the
--export flag with the
flag, and to create a dedicated export preset for automated export:
godot --path path/to/project --export "pck" game_name.pck
PCK versus ZIP pack file formats¶
Each format has its upsides and downsides. PCK is the default and recommended format for most use cases, but you may want to use a ZIP archive instead depending on your needs.
- Uncompressed format. Larger file size, but faster to read/write.
- Not readable and writable using tools normally present on the user's operating system, even though there are third-party tools to extract and create PCK files.
- Compressed format. Smaller file size, but slower to read/write.
- Readable and writable using tools normally present on the user's operating system. This can be useful to make modding easier (see also Exporting packs, patches, and mods).
