Various Installing a different Unity version

How to install a different Unity version

Quick install (macOS only)

If you need to install Unity, you would need to specify the preferred version in your codemagic.yaml file like this:

workflows:
  unity-workflow:
      ...
      environment:
        unity: YOUR-DESIRED-UNITY-VERSION # e.g. 2021.3.6f1

This will automatically install the specified Unity version to the build machine and set the UNITY_HOME to /Applications/Unity/Hub/Editor/<YOUR-DESIRED-UNITY-VERSION>/Unity.app and you can continue building your app as described here.

The available Unity versions are the following:

2023.1.10f1
2023.1.17f1

2022.2.16f1
2022.3.5f1
2022.3.7f1
2022.3.10f1
2022.3.11f1
2022.3.17f1
2022.3.19f1

2021.3.4f1
2021.3.6f1
2021.3.7f1
2021.3.9f1
2021.3.10f1
2021.3.11f1
2021.3.12f1
2021.3.13f1
2021.3.15f1
2021.3.20f1
2021.3.23f1
2021.3.24f1
2021.3.27f1
2021.3.28f1

2020.3.15f2
2020.3.21f1
2020.3.38f1
2020.3.40f1
2020.3.41f1

If you can’t find your desired Unity version in the list, please contact us here.

Notes:

These versions are the Unity Editor (macOS x86_64), and have only the macOS, Android, and iOS modules.
Mac machines with Apple silicon support Unity built for x86_64 architecture.
If your app requires additional modules then you need to install it using Unity Hub CLI like this: /Applications/Unity\ Hub.app/Contents/MacOS/Unity\ Hub -- --headless install-modules --version <UNITY_VERSION> -m windows-mono, this will install the windows modules for the specified <UNITY_VERSION>.

Download and install from Unity Hub

It is possible to use the Unity Hub CLI to download and install a different Unity Editor version and target support files for that version.

License activation and return takes place with the Unity version already installed on the machine, but building of the Xcode project or Android binary will use the version of Unity you install.

Getting the Unity version number and changeset id

In order to install a different version, you can use the info from the ProjectSettings/ProjectVersion.txt file which has the unity version and changeset that the project uses. You only need to add this script.

Mac
Windows

    scripts:  
      - name: Retrieve Used Unity Version
        script: | 
          UNITY_VERSION=$(echo $(sed -n '1p' ProjectSettings/ProjectVersion.txt) | cut -c 18-)
          UNITY_VERSION_CHANGESET=$(echo $(sed -n '2p' ProjectSettings/ProjectVersion.txt) | cut -d "(" -f2 | cut -d ")" -f1 | xargs)
          echo "UNITY_VERSION=$UNITY_VERSION" >> $CM_ENV
          echo "UNITY_VERSION_CHANGESET=$UNITY_VERSION_CHANGESET" >> $CM_ENV
          echo "UNITY_HOME=/Applications/Unity/Hub/Editor/${UNITY_VERSION}/Unity.app" >> $CM_ENV #to update the default Unity home.

    scripts: 
      - name: Retrieve Used Unity Version
        script: | 
          $env:UNITY_VERSION=(Get-Content ProjectSettings/ProjectVersion.txt -TotalCount 1).Substring(17)
          $env:UNITY_VERSION_CHANGESET=([regex] "\((.*)\)").match((Get-Content ProjectSettings/ProjectVersion.txt -TotalCount 2)).groups[1].value
          Add-Content -Path $env:CM_ENV -Value "UNITY_VERSION=$UNITY_VERSION"
          Add-Content -Path $env:CM_ENV -Value "UNITY_VERSION_CHANGESET=$UNITY_VERSION_CHANGESET"
          Add-Content -Path $env:CM_ENV -Value "UNITY_HOME=C:\Program Files\Unity\Hub\Editor\$env:UNITY_VERSION\Editor"

Activating Unity

Even though you are installing a different version of Unity to build your apps with, you should activate your license using the default Unity version already installed on the machine. Unity Hub CLI commands do not work correctly if a license is not already active on the machine.

Unity installation script

After activating the Unity license as usual, add the following script to install the desired version and modules you wish to use. The example below uses Unity Hub CLI commands to install the specified Unity version as well as the Android and iOS Build Support modules.

Mac
Windows

  scripts: 
    - name: Install Unity version
      script: |  
        /Applications/Unity\ Hub.app/Contents/MacOS/Unity\ Hub -- --headless install --version $UNITY_VERSION --changeset $UNITY_VERSION_CHANGESET -a arm64 # -a x86_64
        /Applications/Unity\ Hub.app/Contents/MacOS/Unity\ Hub -- --headless install-modules --version $UNITY_VERSION -m ios android -a arm64 # -a x86_64

  scripts: 
    - name: Install Unity version
      script: |  
        New-Item ".\install-unity.bat" #create an empty batch file
        Set-Content install-unity.bat "`"$env:UNITY_HUB`" -- --headless install -v $env:UNITY_VERSION --changeset $env:UNITY_VERSION_CHANGESET"
        Add-Content install-unity.bat "`"$env:UNITY_HUB`" -- --headless install-modules --version $env:UNITY_VERSION -m ios android"
        Start-Process -FilePath ".\install-unity.bat" -Wait -NoNewWindow #start executing the batch file

Building with the newly installed Unity version

Use the Unity version you installed on the machine:

Mac
Windows

  scripts:
    - name: Build the Unity app
      script: |  
        $UNITY_HOME/Contents/MacOS/Unity -batchmode -quit -logFile -projectPath . -executeMethod BuildScript.$BUILD_SCRIPT -nographics

  scripts:
    - name: Build the Unity app
      script: |  
        cmd.exe /c "$env:UNITY_VERSION" -batchmode -quit -logFile -projectPath . -executeMethod BuildScript.$env:BUILD_SCRIPT -nographics
