#Unity cloud build analysis failed code#
Root annotations are less complicated to use but can also lead to the Unity linker preserving some code that it should strip. The Unity linker doesn’t strip any code that is marked as a root. Root annotations identify parts of your code as roots.There are two broad approaches you can use to annotate your code to preserve it from the managed code stripping process: Annotations either provide general guidance to the Unity linker about which code patterns it shouldn’t strip, or instructions not to strip a specific, defined section of code. This is helpful if your application produces runtime code which doesn’t exist when Unity performs the static analysis for example, through reflection. You can use annotations to prevent the Unity linker from stripping specific sections of your code. Test your application thoroughly and make careful use of attributes and link.xml files to ensure that the Unity linker doesn’t strip vital code.
Use this setting only for projects where a compact build size is extremely important. This search can take much longer than for lower stripping levels. At this setting, Unity prioritizes size reduction more than code stability and removes as much code as possible. Unity performs an extensive search of all assemblies to find unreachable code. Although Unity doesn’t strip all possible unreachable code, this setting does increase the risk of undesirable or unexpected behavior changes. This setting applies a set of rules that strips more types of code patterns to reduce the build size.
Unity partially searches all assemblies to find unreachable code. This setting applies a set of rules that removes some unused code but minimizes the likelihood of unintended consequences, such as changes in behavior of runtime code that uses reflection. Unity searches some user-written assemblies and all UnityEngine and. This setting is useful for projects where usability is of higher priority than build size.This is the default setting if you use the IL2CPP scripting backend. This setting is the least likely to cause any unexpected runtime behavior. Unity doesn’t remove any user-written code. Unity searches only the UnityEngine and the. This setting is visible only and is the default setting if you use the Mono scripting backend. Set the Managed Stripping Level property to the desired value.In Other Settings, navigate to the Optimization heading.Go to Edit > Project Settings > Player.To change the Managed Stripping Level property: The Unity linker removes more code at the higher settings which reduces the final size of your build, though the expanded search means that each build takes longer to produce. As you increase the setting from Minimal to High, the rules enable the linker to search through more assemblies for unreachable code. The Managed Stripping Level property determines the set of rules that the Unity linker follows when it analyzes and strips your application’s code. Configure managed code stripping The Managed Stripping Level property To prevent Unity removing specific parts of your code, use annotations to indicate which parts of your code base the Unity linker should preserve. You can configure the level of code stripping Unity performs for your project using the Managed Stripping Level setting. This analysis only includes code that exists at build time because runtime generated code doesn’t exist when Unity performs the static analysis. The static analysis identifies any classes, portions of classes, functions, or portions of functions that can’t be reached during execution. Unity uses a tool called the Unity linker to perform a static analysis of the code in your project’s assemblies. More info See in Glossary in your project, assemblies that are part of packages and plugins, and assemblies in. Managed code stripping removes code from managed assemblies, including assemblies built from the C# scripts A piece of code that allows you to create your own Components, trigger game events, modify Component properties over time and respond to user input in any way you like. During the build process, Unity removes unused or unreachable code through a process called managed code stripping, which can significantly decrease your application’s final size.
