Unity Editor扩展生成脚本并自动挂载到对应生成的预制体上

监听指定文件夹预制体变动

public class CustomAssetPostprocessor : AssetPostprocessor
{//所有的资源的导入，删除，移动，都会调用此方法，注意，这个方法是static的public static void OnPostprocessAllAssets( string[] importedAsset, string[] deletedAssets, string[] movedAssets, string[] movedFromAssetPaths ){//List<string> formList = new List<string>();//string history = Path.Combine( Application.persistentDataPath, "GenerateUIFormHistory.cachedat" );//if ( File.Exists( history ) )//{//    string genHistory = File.ReadAllText( history );//    string[] forms = genHistory.Split( ';' );//    formList = new List<string>( forms );//}List<string> movedAssetsList = new List<string>( movedAssets );foreach ( string url in importedAsset ){if ( url.StartsWith( "Assets/BundleRes/UI/Form" ) && url.EndsWith( ".prefab" ) && !movedAssetsList.Contains( url ) ){//if ( !formList.Contains( str ) )//{//    NewFormPrefabProc( str );//}
#if UNITY_2020_1_OR_NEWERstring form = Path.GetFileNameWithoutExtension( url );if ( !Directory.Exists( $"Assets/Scripts/UIForms/{form}" ) )
#endif{NewFormPrefab( url );}}}foreach ( string url in deletedAssets ){if ( url.StartsWith( "Assets/BundleRes/UI/Form" ) && url.EndsWith( ".prefab" ) && !movedAssetsList.Contains( url ) ){//Log.PINK( $"Check uIForm prefab deleted: {url}" );var formName = Path.GetFileNameWithoutExtension( url );var dependScriptFolder = $"Assets/Scripts/UIForms/{formName}";if ( Directory.Exists( dependScriptFolder ) ){Directory.Delete( dependScriptFolder, true );File.Delete( dependScriptFolder + ".meta" );//Log.PINK( $"Delete depend ScriptFolder: {dependScriptFolder}\nDelete depend scripts: {formName}.cs,{formName}Manager.cs" );}}}}
}

脚本生成
