Hinweis

Git commands can be powerful and sometimes destructive. Always make sure you understand the implications of a command before running it, especially those that alter history, such as git reset, git rebase, and git filter-branch. It’s often a good idea to create backups or work on a separate branch when experimenting with these commands.

GitHub Actions are YAML files designed to automate repetitive tasks using predefined workflows and variables, enabling seamless integration and continuous deployment. They enhance productivity by managing build, test, and deployment processes directly within the GitHub environment.

KBVE API GROQ

These are the custom notes on our github actions!

ci-patch.yml

The ci-patch.yml GitHub Action is designed to automate the process of creating pull requests for branches that follow a naming pattern starting with “patch”. When a push event occurs on any of these branches, the action triggers and runs on the latest version of Ubuntu. It first checks out the code using the actions/checkout action. Then, it uses the diillson/auto-pull-request action to automatically create a pull request from the patch branch to the dev branch. The pull request will have a title indicating the source branch and a body containing the message “An automated PR”. Additionally, the pull request will be labeled with “auto-pr”.

name: CI Patch

on:
  push:
    branches:
      - 'patch*'

jobs:
  handle:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout
        uses: actions/checkout@v4

      - name: Auto-Pull
        uses: diillson/auto-pull-request@latest
        with:
          github_token: ${{ secrets.GITHUB_TOKEN }}
          destination_branch: 'dev'
          pr_title: 'Pulling ${{ github.ref }} into Dev'
          pr_body: |
            *An automated PR*
          pr_label: 'auto-pr'

kbve-shell

Example of calling the KBVE Shell

-   name: React Fish & Chip
    if: needs.alter.outputs.reactfishchip == 'true'
    uses: ./.github/actions/kbve-shell

        with:
            name: Test results (all modes)
            path: ${{ steps.testRunner.outputs.artifactsPath }}

• Remember that you will need a valid Unity license for this action!

Here is step-by-step breakdown of a Unity GitHub Action

1. Define the Workflow

   name: Unity Test Runner
   

   • The name field sets the name of the workflow, making it easier to identify in the GitHub Actions tab.

2. Specify the Trigger Events

   on: [push, pull_request]
   

   • The on field specifies the events that trigger this workflow. Here, it triggers on push and pull_request events.

3. Define the Job and Environment

   jobs:
     test:
       runs-on: ubuntu-latest
   

   • The jobs field defines the jobs that will run as part of this workflow. The test job runs on the ubuntu-latest environment, which provides a clean and consistent Linux environment for running the tests.

4. Set Up the Matrix Strategy

       strategy:
         matrix:
           projectPath: [path/to/your/project]
           unityVersion: [2020.3.11f1, 2021.1.13f1]
   

   • The matrix strategy allows you to define multiple configurations for your jobs. Here, it sets up multiple Unity versions and project paths to test against, ensuring compatibility across different environments.

5. Checkout the Repository

       steps:
       - name: Checkout repository
         uses: actions/checkout@v2
   

   • The steps field lists the steps in the job. The first step uses the actions/checkout action to clone the repository, providing access to the codebase for subsequent steps.

6. Cache Unity Packages

       - name: Cache Unity packages
         uses: actions/cache@v2
         with:
           path: ~/.local/share/unity3d/Unity/
           key: ${{ runner.os }}-unity-${{ matrix.unityVersion }}
           restore-keys: |
             ${{ runner.os }}-unity-
   

   • Caching saves downloaded Unity packages between workflow runs, reducing the time needed for setup. The cache is identified by a unique key based on the runner OS and Unity version.

7. Run Unity Test Runner

       - name: Run Unity Test Runner
         uses: game-ci/[email protected]
         id: testRunner
         env:
           UNITY_LICENSE: ${{ secrets.UNITY_LICENSE }}
         with:
           projectPath: ${{ matrix.projectPath }}
           unityVersion: ${{ matrix.unityVersion }}
           githubToken: ${{ secrets.GITHUB_TOKEN }}
           customParameters: '-nographics'
   

   • This step runs the Unity Test Runner action:
     • uses specifies the action to run.
     • id gives this step an identifier for later reference.
     • env sets environment variables, including UNITY_LICENSE, which is essential for running Unity in batch mode.
     • with specifies parameters for the action:
       • projectPath sets the path to the Unity project.
       • unityVersion specifies the Unity version.
       • githubToken is used for authentication.
       • customParameters allows passing additional parameters to Unity, such as -nographics for headless execution.

8. Upload Test Results

       - name: Upload Test Results
         uses: actions/upload-artifact@v2
         if: always()
         with:
           name: Test results (all modes)
           path: ${{ steps.testRunner.outputs.artifactsPath }}
   

   • This step uploads the test results as artifacts:
     • if: always() ensures this step runs regardless of the previous step’s outcome.
     • with specifies parameters for the upload:
       • name sets the artifact’s name.
       • path specifies the file path to upload, using the output from the testRunner step.

Hinweis

• Unity License: Ensure you have a valid Unity license stored as a GitHub Secret UNITY_LICENSE. This license is required to run Unity in batch mode.
• Matrix Strategy: Testing against multiple Unity versions and project paths ensures comprehensive coverage and compatibility.
• Caching: Utilizing the cache can significantly speed up workflow runs by reusing previously downloaded Unity packages.
• Artifact Upload: Storing test results as artifacts allows you to review the outcomes of your tests even after the workflow completes, facilitating debugging and quality assurance.

Submodules

Git submodules are a powerful feature that allows you to include and manage external repositories within your own project. By embedding one Git repository as a subdirectory of another, submodules enable the use of libraries or dependencies while maintaining their own version control. This setup ensures that each submodule retains its history and can be updated independently, providing modularity and reducing code duplication. Managing submodules requires specific commands to clone, update, and commit changes, but it offers a robust way to handle complex projects with multiple dependencies, keeping the main repository clean and organized.

Hinweis

These are notes and guides on how to build out submodules inside of Git, so that you can control certain plugins throughout multiple repos effortlessly. This can go into private packages later on, if we need to.

The shift to the private packages will come as we grow bigger and require more control.

Submodule Symbolic Link

Submodule symbolic links provide a method to seamlessly integrate multiple directories from different repositories without duplicating the contents. By creating symbolic links, you can reference submodules in a way that allows for easy navigation and management within your main project directory. This approach avoids the common pitfalls associated with managing multiple directories, such as redundancy and synchronization issues. Symbolic links effectively act as shortcuts, pointing to the actual location of the submodule, thereby streamlining your workflow and maintaining a clean project structure. Utilizing symbolic links in conjunction with submodules can significantly enhance the organization and efficiency of handling external dependencies in complex projects.

KBVE Module Example

Suppose we have already added our submodule for an Unity project, via KBVE/UnitySubModule and wanted to link them into our source, well this is how:

Create a folder inside of Assets named Plugins and then cd into it:

Example of the shell, do not copy and paste, make sure you read through the commands and swap out the right variables!

cd ./unityRootProject
cd ./Assets
mkdir Plugins
cd ./Plugins

Once inside the Plugins folder, we can execute the symbolic link using the ln command, like this:

ln -s ../../submodules/UnitySubModules/Vuplex

---

Scripts

Script commands for Git act as powerful helper scripts that automate and streamline various Git operations. These commands can simplify complex workflows by combining multiple Git actions into a single executable script. For instance, shell commands can automate the process of staging changes, committing with a message, and pushing to the current branch, saving developers time and reducing the risk of errors. Thus, by leveraging the flexibility of shell scripting, developers can create custom workflows tailored to their specific needs, enhancing productivity and ensuring consistent Git practices across projects.

Commit

The commit command stages all changes, commits them with the message “Minor change sync,” and pushes the commit to the current branch. This sequence ensures that all modifications are saved and synchronized with the remote repository.

branch=$(git rev-parse --abbrev-ref HEAD) && git add . && git commit -m "Minor change sync" && git push origin $branch

This command does the following:

1. Environmentals:

   branch=$(git rev-parse --abbrev-ref HEAD)
   

   Stores the current branch name in the branch variable.

2. Git Add

   git add .
   

   Stages all changes.

3. Commit

   git commit -m "Minor change sync"
   

   : Commits the changes with the message “Minor change sync”.

4. Push:

   git push origin $branch
   

   Pushes the changes to the current branch on the remote repository.

This way, you don’t need to manually replace the branch name each time.
