root | 根 GameObject。 |
GameObject 处理 GameObject。
遍历从 root
开始的对象层级视图,然后返回实现类型为 <T> 的事件处理程序的 GameObject。
注意:遍历从根对象向上执行,而不是向下执行。

public class GetEventHandlerExample : MonoBehaviour { // Find the GameObject which implements IDragHandler
void Start() { GameObject handlerObject = ExecuteEvents.GetEventHandler<IDragHandler>(this.gameObject);
if (handlerObject == null) Debug.Log("Drag Handler not found."); else Debug.Log("Drag Handler is attached to GameObject '" + handlerObject.name + "'"); } }
