想将EventSystem封装一下，手机端触控操作的手势合并一下 相关一些介绍以及思路在我的这篇文字里面：EventSystem
总的事件分配管理

using System.Collections; using System.Collections.Generic; using UnityEngine; public delegate void DeleGameObject(GameObject obj); public delegate void DeleFloat(float f); public delegate void DeleBool(bool b); public delegate void DeleInt(int i); public delegate void DeleFloatObj(GameObject obj,float f); public delegate void DeleIntObj(GameObject obj,int i);进入事件
using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.EventSystems; public class PointerEnterHandler : MonoBehaviour, IPointerEnterHandler { public DeleGameObject callback; public void OnPointerEnter(PointerEventData eventData) { callback?.Invoke(eventData.pointerEnter); } }事件处理
using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.EventSystems; public class cube : MonoBehaviour { void Start () { UIEventMgr.AddDoubleClick(gameObject, OnDoubleClick); UIEventMgr.AddClick(gameObject, OnClick); //Invoke("RemoveEvent", 5); } private void OnDoubleClick(GameObject obj) { Debug.LogError(obj.name); } void RemoveEvent() { UIEventMgr.RemoveClick(gameObject); UIEventMgr.RemoveDoubleClick(gameObject); } private void OnClick(GameObject obj) { Debug.LogError("cube_click"); } }需要多添加一个层级就多加一个层就好
