-- 场景、模型都加载完成后，绑定拖拽、点击监听
-- 与每个模型同级，搞了一个heroItem，仅有boxCllider（碰撞体 碰撞范围）、selfDragTarget/PointerClickHandler/UIEventListener脚本/组件
-- TeamPVEGround（self._sceneTouchRoot)挂了一个InteractiveModelHelper脚本，里面存了3个gameObj(plane) 3个Clicks(PointerClickHandler) 3个Drags（selfDragTarget）
-- TeamPVEModelCore类：1.持有modeScene类，传递click、drag回调方法；2.加载箭头，刷新箭头
-- modelScene类：管理drag、click集合，self._dragEvents/self._clickEvents，key为选中的gameobjName,value为对应的click drag事件类
--  ModelClickEvent(字段：name/clickEvent(即PointerClickHandler实例)  方法：self._clickEvent:OnPointerClickCallback) self._clickEvent:ClearDragCallBack() release释放
--  ModelDragEvent(字段：name/_dragEvent(即selfDragTarget实例)  方法：    self._dragEvent:SetDragCallback(self) 以及各种拖拽回调方法     self._dragEvent:CleanLuaDelegates() self._dragEvents = nil
