r | 在其中绘制预览的矩形。 |
background | 背景图像。 |
实现此方法可创建您自己的交互式自定义预览。交互式自定义预览用于检视面板和对象选择器的预览区域。
实现此方法(而不是 OnPreviewGUI)以显示交互式自定义预览。如果某些预览是交互式,而其他预览不是,则可以同时实现两种方法。
重写方法应使用传入的矩形,并渲染资源预览。
默认实现为无操作。
**注意:**检视面板预览仅限于持久对象(资源)的主编辑器。例如 GameObjectInspector、MaterialEditor、TextureInspector 等。
这意味着组件当前无法具有自己的检视面板预览。
using UnityEngine; using UnityEditor;
// Create an editor window which can display a chosen GameObject. // Use OnInteractivePreviewGUI to display the GameObject and // allow it to be interactive.
public class ExampleClass: EditorWindow { GameObject gameObject; Editor gameObjectEditor;
[MenuItem("Example/GameObject Editor")] static void ShowWindow() { GetWindowWithRect<ExampleClass>(new Rect(0, 0, 256, 256)); }
void OnGUI() { gameObject = (GameObject) EditorGUILayout.ObjectField(gameObject, typeof(GameObject), true);
GUIStyle bgColor = new GUIStyle(); bgColor.normal.background = EditorGUIUtility.whiteTexture;
if (gameObject != null) { if (gameObjectEditor == null) gameObjectEditor = Editor.CreateEditor(gameObject);
gameObjectEditor.OnInteractivePreviewGUI(GUILayoutUtility.GetRect(256, 256), bgColor); } } }
