RunBeforeClassAttributeConstructor

参数

描述

Add this attribute to a callback method to mark that this callback must be run before any callbacks that are part of the specified class.

To define dependencies for a callback, use the following attributes: RunAfterClassAttribute, RunBeforeClassAttribute RunAfterAssemblyAttribute, RunBeforeAssemblyAttribute RunAfterPackageAttribute, RunBeforePackageAttribute When the callback is invoked, Unity generates a dependency graph and uses topological sorting to ensure that all dependencies are run in sequence based on their dependencies. If callbacks dependencies are not present in the project then the instruction will be ignored during the generation of the dependency graph.

Note: Defining callback dependencies is currently only supported by the AssetPostprocessor.OnPostprocessAllAssets callback.
