🛠 Setup & Configuration

This page explains how to set up your Unity-CI-CD environment, configure required secrets, and control pipeline variables.

---

🔑 Required Secrets

You must add these under your repository:
GitHub → Settings → Secrets → Actions

Secret Name	Description
UNITY_LICENSE	Base64-encoded Unity license file or .ulf string
UNITY_EMAIL	Unity account email address
UNITY_PASSWORD	Unity account password
CICD_PAT	GitHub Personal Access Token for workflow dispatch

📖 See detailed setup for each secret:
Required Secrets

⚙️ Optional Secrets (Per Deploy Target)

Depending on your deploy targets, you may also need:

Secret Name	Purpose
SLACK_WEBHOOK	Slack webhook URL for notifications
DISCORD_WEBHOOK	Discord webhook URL for notifications
ITCH_USERNAME	itch.io username for Butler uploads
ITCH_PROJECT	itch.io project identifier
FIREBASE_TOKEN	Firebase CLI authentication token
AWS_ACCESS_KEY_ID	AWS key for S3 deploy
AWS_SECRET_ACCESS_KEY	AWS secret for S3 deploy
(and others — see Deployment Guide)

---

📋 Example Parameters

Parameter	Description
UNITY_VERSION	Unity version (e.g., 2022.3.14f1)
PROJECT_NAME	Project name used in builds/artifacts
BUILD_TARGETS	JSON array of build targets (e.g., [ "WebGL" ])
DEPLOY_TARGETS	JSON array of deploy targets (e.g., [ "gh-pages" ])
USE_GIT_LFS	Whether to enable Git LFS (default: false)
EXCLUDE_UNITY_TESTS	Whether to skip tests (default: false)

---

🏗 Example .github/config Files

For fallback defaults, you can create these files in .github/config:

• defaults.json → Defines fallback values for pipeline variables.
• deploy-targets.json → Maps deploy targets to required OS.
• target-platforms.json → Lists supported Unity build platforms.

💡 Note: Repository variables override config files, and manual workflow inputs override both.

The architecture of the .config files can be found here

🏆 Parameter Resolution Priority

When the pipeline resolves parameters (like unityVersion, buildType, deployTargets), it follows this priority order:

Priority Rank	Source	Description
🥇 1	Workflow Dispatch Inputs	Passed when manually running workflows via the GitHub UI or gh workflow run
🥈 2	Repository Variables	Set under Settings → Variables → Actions in your GitHub repository
🥉 3	Config Files	Fallback defaults stored in .github/config/*.json (e.g., defaults.json)

For example:

• If you set inputs.unityVersion in a manual run, it overrides both the UNITY_VERSION repo variable and the defaults in the config file.
• If no manual input is provided, the pipeline checks for a repository variable.
• If neither is provided, the pipeline falls back to the config file.

Tip:
You can check or change repository variables under GitHub → Settings → Variables → Actions.
Config files live in .github/config/ and define project-wide defaults.
