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_NEWER
                string 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/{

                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

    private static void NewFormPrefab( string assetPath )

        {
    
    
            Log.Error( $"NewFormPrefabProc 传入路径为空或者空格: {
      
      assetPath}" );
            return;
        }

        var pathclips = assetPath.Split( '/' );
        var fileName = pathclips[ pathclips.Length - 1 ].Split( '.' )[ 0 ];
        string file = fileName + "";
        if ( !fileName.EndsWith( "Form" ) )
        {
    
    
            if ( fileName.EndsWith( "form" ) )
            {
    
    
                file = fileName.Replace( "form", "Form" );
            }
            else
            {
    
    
                file = fileName + "Form";
            }
        }

        //try

        //    string genHistory = string.Empty;

        //}
        //catch ( System.Exception e )
        //{

        //}
        //预制体操作
        //var instance = PrefabUtility.LoadPrefabContents( assetPath );

        //PrefabUtility.SaveAsPrefabAsset( instance, "Assets/BundleRes/UI/Form/aaa2.prefab" );
        //PrefabUtility.UnloadPrefabContents( instance );

        var formClsName = file + "";
        var managerClsName = $"{
      
      file}Manager";
        var outputFolder = $"Assets/Scripts/UIForms/{
      
      file}/";
        if ( !Directory.Exists( outputFolder ) )
        {
    
    
            Directory.CreateDirectory( outputFolder );
        }

        EditorUtility.DisplayProgressBar( "Generate UIForm Derived ClassScript", $"class {

脚本自动挂载

  public static string generateNamespaceName = "";
    public static string generateClassName = "generateClassName";
    public static string generatePrefabPath = "generatePrefabPath";
    [UnityEditor.Callbacks.DidReloadScripts]
    private static void OnScriptUpdateLoaded( )
    {
    
    
        string className = EditorPrefs.GetString( generateClassName );
        if ( string.IsNullOrEmpty( className ) )
        {
    
    
            return;
        }

        EditorUtility.DisplayProgressBar( "Mount scripts", $"{
      
      className} install...", 0f );

        var assemblies = AppDomain.CurrentDomain.GetAssemblies( );

        var defaultAssembly = assemblies.First( assembly => assembly.GetName( ).Name == "Assembly-CSharp" );

        var typeName = string.IsNullOrEmpty( generateNamespaceName ) ? className : generateNamespaceName + "." + className;

        var type = defaultAssembly.GetType( typeName );

        if ( type == null )
        {
    
    
            Debug.Log( "编译失败" );
            EditorUtility.ClearProgressBar( );
            return;
        }

        string prefabPath = EditorPrefs.GetString( generatePrefabPath );

        //为开发者提供额外处理接口
        try
        {
    
    
            GameObject prefabInstance = PrefabUtility.LoadPrefabContents( prefabPath );

            EditorUtility.DisplayProgressBar( "Mount scripts", $"{
      
      className} install...", 0.618f );

            var scriptComponent = prefabInstance.GetComponent( type );

            if ( !scriptComponent )
            {
    
    
                scriptComponent = prefabInstance.AddComponent( type );
            }

            AdditionalConfigurationForNewForm( prefabInstance );

            EditorUtility.DisplayProgressBar( "Mount scripts", $"{
