FUNDAMENTALS

Continuous Integration

The Wonderland Editor Docker Image allows setting up efficient continuous integration and delivery of Wonderland Engine projects.

This page describes how to set up efficient automated builds and deployment with the most popular CI services:

Gitlab CI / Gitlab Pages 

Using any docker runner (e.g. the gitlab.com shared runners) on Gitlab.

Configuration 

Your .gitlab-ci.yml should look like follows:

stages:
  - build

pages:
  image: wonderlandengine/editor:latest
  stage: build
  tags:
    - docker
  script:
    - WonderlandEditor --windowless --credentials "$WLE_CREDENTIALS" --package --project Project.wlp
    - gzip -k deploy/*
    - mv deploy public
  cache:
    key: ${CI_COMMIT_REF_SLUG}
    paths:
      - cache/
  artifacts:
    paths:
      - public

$WLE_CREDENTIALS is a variable containing email:password. We will configure it in the next step.

Variables 

Find variables for Gitlab CI in the Gitlab web interface: Settings > CI/CD > Variables.

Click “Add Variable” and name it WLE_CREDENTIALS and set its value to email:password, where email is the email of your Wonderland Engine account and password the matching password.

For public projects make sure to enable “Protect variable” to prevent unmerged merge requests from being able to access the CI variable.

Cache 

The most time-consuming task in the editor is compressing textures. This is significantly faster, if the results are cached (in the cache/ directory). It is therefore useful to either specify this folder for the CI cache, or check in the files into source control.

GitHub Workflows / GitHub Pages 

Using any docker-enabled runner (e.g. the GitHub hosted runners) on GitHub.

Configuration 

Your workflow file (e.g. .github/workflows/github-pages.yml) should look like follows:

jobs:
  package:
    runs-on: ubuntu-latest
    container:
      image: wonderlandengine/editor:latest
    steps:
    - uses: actions/checkout@v2
    - name: Package
      run: /usr/local/bin/entrypoint.sh WonderlandEditor --windowless --package --project Project.wlp --credentials "$WLE_CREDENTIALS"
      env:
          WLE_CREDENTIALS: ${{ secrets.WLE_CREDENTIALS }}
    - name: Gzip
      run: gzip -k deploy/*
    - name: Upload package artifact
      uses: actions/upload-artifact@v2
      with:
        name: Project-deploy
        path: deploy/
  deploy:
    needs: package
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v2
    - name: Download package artifact
      uses: actions/download-artifact@v2
      with:
        name: Project-deploy
        path: deploy
    - name: Deploy to GitHub Pages
      uses: JamesIves/github-pages-deploy-action@4.1.1
      with:
        branch: gh-pages
        folder: deploy

Project-deploy is the name of the artifact which contains the contents of the deploy/ folder.

Project.wlp is your project file.

$WLE_CREDENTIALS is a secret containing email:password. We will configure it in the next step.

Secrets 

Find secrets for GitHub Workflows in the GitHub web interface: Settings > Secrets > Repository Secrets.

Click “New repository secret” on the top right and name it WLE_CREDENTIALS and set its value to email:password, where email is the email of your Wonderland Engine account and password the matching password.

Secrets are not passed to pullrequests from forks, which means your workflow may not run for pullrequests from outside collaborators.
