Unity 编辑器扩展-自定义窗口鼠标事件(左键/右键)

在绘制自定义窗口控件的时候,有时会需要监听鼠标在当前控件上的操作,这时候一般是使用Event类来实现,演示代码如下:

class 技能编辑器 : EditorWindow
{
    [MenuItem("工具/技能编辑器")]
    static void 技能编辑()
    {
        GetWindow<技能编辑器>(false, "技能编辑器");
    }
    Rect testArea = new Rect(200,200,100,100);
    private void OnGUI()
    {
        GUI.Box(testArea, "测试区域", new GUIStyle("ButtonMid"));
        int boxHashCode = "BoxId".GetHashCode();
        int boxID = GUIUtility.GetControlID(boxHashCode, FocusType.Passive);
        Event current = Event.current;
        if (current.rawType == EventType.MouseUp)//鼠标抬起事件
        {
            if (GUIUtility.hotControl == boxID)
            {
                Debug.Log("鼠标抬起事件");
                GUIUtility.hotControl = 0;
                current.Use();
            }
        }
        Vector2 mousePosition = new Vector2(current.mousePosition.x, current.mousePosition.y);
        if
