Definition
- Type: Class
- Namespace: UnityEditor.Callbacks
- Assembly: UnityEditor.CoreModule
- Inherits from: Attribute
[AttributeUsage(AttributeTargets.Method, AllowMultiple = true)]public class RunBeforeClassAttribute : Attribute
Remarks
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(string[], string[], string[], string[], bool) callback.
Examples
using UnityEditor;using UnityEditor.Callbacks;class RunFirst : AssetPostprocessor{ [RunBeforeClass(typeof(RunNext))] static void OnPostprocessAllAssets(string[] importedAssets, string[] deletedAssets, string[] movedAssets, string[] movedFromAssetPaths) { }}class RunNext : AssetPostprocessor{ static void OnPostprocessAllAssets(string[] importedAssets, string[] deletedAssets, string[] movedAssets, string[] movedFromAssetPaths) { }}class RunLast : AssetPostprocessor{ [RunAfterClass(typeof(RunNext))] static void OnPostprocessAllAssets(string[] importedAssets, string[] deletedAssets, string[] movedAssets, string[] movedFromAssetPaths) { }}
