Godot Export

A workflow action to automatically export your Godot games. Supports standard and Mono builds!

Contents

How it Works

Automatic Exports

This action automatically reads your export_presets.cfg file to determine which builds to make. Whenever this action runs each of your defined exports will run. The resulting executables will be posted as zip files attached to the created release.

Automatic Release

This action creates a release tagged with a Semantic Version. The zip files containing the export results will be attached to this release. More info about releases can be found below.

Setting Up Export Presets

Define at least 1 export preset by going to Project -> Export in the Godot editor and creating a configuration. Set the file name in the "Export Path" box. This is how the action knows how to name your binary. Notice how the below image has "win.exe" in the "Export Path" for my windows export. Your executables can be named however you like, as long as they include the appropriate extension .exe, .x86_64, etc.

NOTE: The file extension for the Mac OSX export must be anything but .zip for versions of Godot before 3.2. If the Mac OSX export file extension is .zip for a Godot version earlier than 3.2, then your project source files will be exported instead of a Mac application. This was a known issue with the Godot command line export. For reference, I used a .z file extension to make it work for my Mac OSX builds.

Workflow Configuration

Inputs

Required Inputs

  • godot_executable_download_url
    • The Linux Headless version of Godot that you want to export your project with. For example, to use the current stable of version of Godot your value will be https://downloads.tuxfamily.org/godotengine/3.1.2/Godot_v3.1.2-stable_linux_headless.64.zip. If you do not use the Linux Headless version exporting will fail.
  • godot_export_templates_download_url
    • The link to the .tpz archive of export templates. Can be found at https://downloads.tuxfamily.org/godotengine. The export templates must be for the same version of Godot that you are using in godot_executable_download_url. For example, the godot_export_templates_download_url that matches the godot_executable_download_url version is https://downloads.tuxfamily.org/godotengine/3.1.2/Godot_v3.1.2-stable_export_templates.tpz
  • relative_project_path
    • The relative path to the directory containing your project.godot file. If your project.godot is at the root of your repository then this value should be ./. Do not include project.godot as part of this path.

Optional Inputs

  • export_debug defaults false
    • If true, godot will export with debugging tools.
  • archive_export_output default false
    • If true, exports will be archived.
    • Note: When create_release is true then exports uploaded to the release may be archived regardless of this setting.
  • archive_single_release_output default true
    • If exports that result in a single file output should be archived when uploading to the release. Setting this to false is useful for exports that use the "Embed PCK" option, as the output executable can be directly uploaded to the release.
    • Note: This input is only used when create_release is true.
  • base_version default 0.0.1
    • The version which new releases start at. The first release will be this version. After that, releases will automatically be 1 patch version ahead of the version of the latest release. To increment minor and major versions simply set the base_version to reflect your desired major and minor versions. When the base_version is set to a higher version than the last release version, the base_version will be used.
    • Note: This input is only used when create_release is true.
  • create_release default true
    • If releases should be automatically created.
  • generate_release_notes default false
    • If release notes should be automatically generated based on commit history. The generated notes will be added as the body of the release.
    • Note: This input is only used when create_release is true.
    • Note: When using the GitHub checkout action, ensure you are fetching the entire project history by including fetch-depth: 0. See the example workflow configuration for more context.
  • use_preset_export_path default false
    • If set to true, exports will be moved to directory defined in export_presets.cfg relative to the root of the Git repository. Prioritized over relative_export_path.
  • relative_export_path default ''
    • If provided, exports will be moved to this directory relative to the root of the Git repository.
  • wine_path default ''
    • The absolute path to the wine binary. If specified, Godot will use this to run rcedit to update Windows exe icons. See the setup Windows icons example configuration.

Environment Variables

Since this action creates releases and uploads the zip file assets, you will need to supply the GITHUB_TOKEN environment variable. For an example on how to do this, see the below example workflow configuration. This environment variable is not needed if you set create_release to false.

Example Configuration

Below is a sample workflow configuration file utilizing this action. This example workflow could be defined in .github/workflows/main.yml. For more information about defining workflows see the workflow docs.

# Whenever a push is made to the master branch then run the job
on: 
  push:
    branches:
      - master

jobs:
  # job id, can be anything
  export_game:
    # Always use ubuntu-latest for this action
    runs-on: ubuntu-latest
    # Job name, can be anything
    name: Export Game Job
    steps:
      # Always include the checkout step so that 
      # your project is available for Godot to export
    - name: checkout
      uses: actions/checkout@v2.3.1
      # Ensure that you get the entire project history
      with:
        fetch-depth: 0
    - name: export game
      # Use latest version (see releases for all versions)
      uses: firebelley/godot-export@v3.0.0
      with:
        # Defining all the required inputs
        # I used the mono version of Godot in this example
        godot_executable_download_url: https://downloads.tuxfamily.org/godotengine/3.3/rc9/mono/Godot_v3.3-rc9_mono_linux_headless_64.zip
        godot_export_templates_download_url: https://downloads.tuxfamily.org/godotengine/3.3/rc9/mono/Godot_v3.3-rc9_mono_export_templates.tpz
        relative_project_path: ./
      env:
        GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

Mono Builds

Mono builds do not require additional configuration. However, if you want to change the build tool that is used (currently defaults to dotnet cli) then you need to supply your own editor settings with the line mono/builds/build_tool. The value of this setting should be a number between 0 and 3. This value corresponds to the build tool dropdown in the editor settings window at Editor Settings -> Mono -> Builds -> Build Tool. You can look at your local editor_settings-3.tres to see what this value should be if you want to match the build tool used during local development.

Android Builds

For Android builds, use the setup-android action before this one in your workflow. The default editor settings file used by this action already provides a default path to the Android SDK. If your path is different then supply your own editor settings file.

Custom Editor Settings

Some Godot configurations are editor-based and not project-based. This includes items like Android paths. This repository provides a base editor settings that will be used by default when exporting your games. However, you can supply a custom editor settings configuration file by simply copying your custom editor settings file to ~/.config/godot/editor_settings-3.tres before this action runs. This action will not overwrite an existing editor_settings-3.tres file.

Tips

Using tag as base_version

You can use git tags to set the release version. For example, using git tag v1.0.0 and then git push --tags results in base-version 1.0.0 when using the following workflow.

# Whenever tag in the form of `v1.0.0` is pushed then run the job

on: 
  push:
    tags:
      - 'v*'

jobs:
  # job id, can be anything
  export_game:
    # Always use ubuntu-latest for this action
    runs-on: ubuntu-latest
    # Job name, can be anything
    name: Export Game Job
    steps:
      # Always include the checkout step so that 
      # your project is available for Godot to export
    - name: checkout
      uses: actions/checkout@v2.3.1
      # Ensure that you get the entire project history
      with:
        fetch-depth: 0
      # separate step to extract the version from the tag name
    - name: get tag from version
      id: tag_version
      run: |
        echo ::set-output name=TAG_VERSION::${GITHUB_REF#refs/tags/v}
    - name: export game
      # Use latest version (see releases for all versions)
      uses: firebelley/godot-export@v3.0.0
      with:
        # Defining all the required inputs
        # I used the mono version of Godot in this example
        godot_executable_download_url: https://downloads.tuxfamily.org/godotengine/3.3/rc9/mono/Godot_v3.3-rc9_mono_linux_headless_64.zip
        godot_export_templates_download_url: https://downloads.tuxfamily.org/godotengine/3.3/rc9/mono/Godot_v3.3-rc9_mono_export_templates.tpz
        relative_project_path: ./
        create_release: true
        base_version:  ${{ steps.tag_version.outputs.TAG_VERSION}} 
      env:
        GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

Supplying a custom editor settings file

Include the following step before this action. For example:

# ...above this line is the workflow job setup
- name: use custom editor settings
  run: |
    mkdir -p ~/.config/godot
    cp ~/path/to/my/editor_settings-3.tres ~/.config/godot/
- name: export game
  uses: firebelley/godot-export@v3.0.0
  # ...the rest of the action config goes here

Setup Windows Icons

In order to configure this action to update your game's Windows exe icon, include the following block before this action. Example:

- name: install wine
  id: wine_install
  run: |
    sudo apt install wine64
    echo ::set-output name=WINE_PATH::$(which wine64)

And then supply this WINE_PATH output to the wine_path input for this action:

- name: export game
  uses: firebelley/godot-export@v3.0.0
  with:
    # ... any other input configuration goes here in accordance with the documentation
    # 
    # read the wine path here that was an output of the wine_install step
    wine_path: ${{ steps.wine_install.outputs.WINE_PATH }}
