Luna Dependencies

Luna Playable is provided as a Unity package and has a number of dependencies which are required before the installation.

Unity Engine (Supported Unity Versions)

Luna Playable enables you to build playable ads in Unity, and so the Unity editor is a natural requirement.

Currently, the Luna exporter and engine support the following Unity versions:

  • 2019.4 (LTS)
  • 2020.3 (LTS)
  • 2021.3 (LTS)

You can download a specific Version from the Unity download archives section for both Windows and Mac.

C# Language Support

Most of these Unity versions all have continuous-integration tests, but it is important to note that it does not mean that 100% of features are supported (For language we support C# 7.0 features and earlier).

Whilst 2018.2-3 works with Luna, we no longer run tests against these versions due to low usage.

Installing Dependencies

Independent Development Environment (IDE)

You can develop using whichever IDE is most convenient for you. If you don't have an IDE then as a recommendation, we would suggest to download Visual Studio since you can also install .NET by using its installer.

Install .NET 4.7

You will need to download .NET package to have the correct framework and libraries to work with Luna. .NET is required for C# (gameplay code) to JavaScript (gameplay code) conversion.

If you are on Windows, you can download .NET 4.7 developer pack, or you can use Visual Studio Installer:

  1. Click the 'Modify' button next to the version of VS you are using
  2. From the window opened select .Net desktop development
  3. In the right hand side of the window (Installation details) new items will appear
  4. Select .NET 4.7 and above (Example of this below)

  1. Next navigate to the 'Individual Components' tab
  2. Search in for '.NET' and select the 4.7 SDK & targeting pack items (Example of this below)

  1. After selecting all these hit 'Modify' in the bottom right and let the items install

MS-Build

MS-Build is a build tool provided by VisualStudio/Mono.Frameworks and is used to compile code packages for Luna Playable. thus is crucial to certain Luna build stages.

For Windows MsBuild is usually located inside:
C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\MSBuild\Current\Bin\MSBuild.exe

If using windows, it is possible to install MSbuild through the visual studio build tools package, which includes the .Net desktop development workload mentioned above. Build tools can be found here.

In some cases Luna could be failing to compile relating to an issue with a missing .NetFramework assembly. Try installing each of the .NetFramework 4.x targeting packs and SDKs through the visual studio installer mentioned above
