Unity扩展-继承GUI组件Button

1. 创建脚本MyButton继承Button

   public class MyButton : Button
   {   
   
   [SerializeField] public AudioClip clickAudio;
   
   public override void OnPointerClick(PointerEventData eventData)
   {
       base.OnPointerClick(eventData);
       if (eventData.button != PointerEventData.InputButton.Left)
           return;
       Debug.Log("MyButton");
   }
   }
   

2. 创建脚本MyButtonEditor继承ButtonEditor；用来在属性检查器里显示自己添加的属性clickAudio。

   [CustomEditor(typeof(MyButton), true)]
   [CanEditMultipleObjects]
   public class MyButtonEditor : ButtonEditor
   {
   private SerializedProperty clickAudio;
   
   protected override void OnEnable()
   {
       base.OnEnable();
       clickAudio = serializedObject.FindProperty("clickAudio");
   }
   
   public override void OnInspectorGUI()
   {
       base.OnInspectorGUI();
       EditorGUILayout.Space();
       serializedObject.Update();
       EditorGUILayout.PropertyField(clickAudio); 
       serializedObject.ApplyModifiedProperties();
   }
   }
   

   PS：MyButtonEditor可以存放到Editor文件夹。存放于Editor文件夹下的资源只在编辑器下可以使用，打包发布时不会一同发布。
