unity3d ci example

Note: This project is a "fork" of https://gitlab.com/gableroux/unity3d-gitlab-ci-example. More information available there.

This project is a PoC to run unity3d tests and builds inside a CI using gableroux/unity3d docker image. It currently creates builds for Windows, Linux, MacOS and webgl. The webgl build is published and accessible via the public artifact folder of your webgl job! This repository is hosted on multiple remotes to provide examples:

• github
• gitlab

Getting started

If you don't have a Unity project yet:

1. Fork this project from github or gitlab
2. Update the readme and remove undesired CI configurations
3. Follow How to activate instructions
4. Configure your CI

If you already have your own project:

1. Copy desired CI file
2. Update the Unity version according to your project version in the CI file. All versions are available at gableroux/unity3d docker image
3. Follow How to activate instructions
4. Configure your CI

Points of interest

This is probably what you're looking for.

Build script

Script passed to the unity3d command line as argument to create builds

• See BuildCommand.cs

CI Configuration

This project will only cover Circle-CI. If you need more information on the gitlab and Travis implementations, go to https://gitlab.com/gableroux/unity3d-gitlab-ci-example

Test files

• editmode tests in Assets/Scripts/Editor/EditModeTests
• playmode tests in Assets/Tests/

How to activate

You'll first need to run this locally. All you need is docker installed on your machine.

1. Clone this project

2. Pull the docker image and run bash inside, passing unity username and password to env

   hint: you should write this to a shell script and execute the shell script so you don't have your credentials stored in your bash history. Also make sure you use your Unity3d email address for UNITY_USERNAME env var.

   UNITY_VERSION=2018.4.3f1
   docker run -it --rm \
   -e "[email protected]" \
   -e "UNITY_PASSWORD=example_password" \
   -e "TEST_PLATFORM=linux" \
   -e "WORKDIR=/root/project" \
   -v "$(pwd):/root/project" \
   gableroux/unity3d:$UNITY_VERSION \
   bash

3. In Unity docker container's bash, run once like this, it will try to activate

   xvfb-run --auto-servernum --server-args='-screen 0 640x480x24' \
   /opt/Unity/Editor/Unity \
   -logFile \
   -batchmode \
   -username "$UNITY_USERNAME" -password "$UNITY_PASSWORD"

4. Wait for output that looks like this:

   LICENSE SYSTEM [2017723 8:6:38] Posting <?xml version="1.0" encoding="UTF-8"?><root><SystemInfo><IsoCode>en</IsoCode><UserName>[...]
   

   If you get the following error:

   Can't activate unity: No sufficient permissions while processing request HTTP error code 401

   Make sure your credentials are valid. You may try to disable 2FA in your account and try again. Once done, you should enable 2FA again for security reasons. See #11 for more details.

5. Copy xml content and save as unity3d.alf

6. Open https://license.unity3d.com/manual and answer questions

7. Upload unity3d.alf for manual activation

8. Download Unity_v2018.x.ulf

9. Open the Unity_v2018.x.ulf file in your favorite text editor and convert it to Base64 (ex.: here: https://www.base64encode.org/)

10. Copy the base64 data to Circle CI's environment variable UNITY_LICENSE_CONTENT.

How to add build targets

Supported build targets can be found here

How to run scripts manually

You can execute the local scripts and specify the path of your Unity executable using UNITY_EXECUTABLE. You may try this in your project before you setup the whole CI so you confirm it works with your current unity version 👍 . All you need to do first is to insert the scripts from https://github.com/qwertyuu/unity-ci-build-scripts in Assets/Editor into your own Assets folder and follow the commands below.

Test

UNITY_EXECUTABLE="/Applications/Unity/Hub/Editor/2018.3.4f1/Unity.app/Contents/MacOS/Unity" \
  ./local_test.sh

Build

UNITY_EXECUTABLE="/Applications/Unity/Hub/Editor/2018.3.4f1/Unity.app/Contents/MacOS/Unity" \
  ./local_build.sh
