Unity Engine Module assemblies - Includes the managed assemblies that make up the Unity Engine, such as.For example, the windows.winmd assembly that is part of the Universal Windows Platform An IAP feature that supports Microsoft’s In App Purchase simulator, which allows you to test IAP purchase flows on devices before publishing your application. Platform SDK assemblies - Includes the managed assemblies specific to a platform SDK.NET class library facade assemblies like netstandard.dll. NET Class Library assemblies - Includes the Mono class libraries such as mscorlib.dll and System.dll, as well as. In general, the Unity linker doesn’t process assemblies included in your project that don’t fall under one of these categories, and excludes them from the Player build.įor each assembly the Unity linker processes, it follows a set of rules based on the classification of the assembly, whether the assembly contains types used in a Scene, and the Managed Stripping Level you have selected for the build.įor the purpose of these rules, assemblies fall into the following classifications: The Unity linker then processes those assemblies, any references of those assemblies, any assemblies declared in a link.xml file, and any assemblies with the AlwaysLinkAssembly attribute. The Unity Editor creates a list of the assemblies that contain types used in any of the Scenes in your Unity project and passes this list to the Unity linker. Upon completion of this static analysis, any remaining unmarked code is unreachable by any execution path through your application code and the Unity linker deletes it from the assembly. The Unity linker then analyzes the roots it has marked to identify, and marks any managed code that these roots depend upon.

More info See in Glossary are root types. In each Scene, you place your environments, obstacles, and decorations, essentially designing and building your game in pieces. Think of each unique Scene file as a unique level. More info See in Glossary in a Scene A Scene contains the environments and menus of your game. A GameObject’s functionality is defined by the Components attached to it. For example, MonoBehaviour-derived classes you add to GameObjects The fundamental object in Unity scenes, which can represent characters, props, scenery, cameras, waypoints, and more. First, it marks root types, methods, properties, and fields. The Unity linker analyzes all the assemblies in your project. For more information, see PlayerSettings.StripEngineCode]. More info See in Glossary script backend that removes unused engine code. The Unity linker is responsible for both managed code stripping and part of the process of engine code stripping, which is a separate process available through the IL2CPP A Unity-developed scripting back-end which you can use as an alternative to Mono when building projects for some platforms. The custom Unity Engine specific parts of the Unity linker aren’t publicly available. The Unity linker is a version of the IL Linker customized to work with Unity. The Unity build process uses a tool called the Unity linker to strip managed code.
