Unity 点击 双击 连击 长按 事件检测(支持PC和移动端)

InputDefine 类：（公共变量、常量、枚举、事件）定义

TouchEvent 类：触摸事件（移动端）

using System.Collections;using System.Collections.Generic;using UnityEngine;/// <summary>触摸事件</summary>public class TouchEvent : MonoBehaviour{public DelClickEvent onClickEvent;private void Update(){if (Input.touchCount > 0){for (int i = 0; i < Input.touchCount; i++){Touch touch = Input.GetTouch(i);if (touch.phase == TouchPhase.Began){if (onClickEvent != null) onClickEvent(InputDefine.IsTouchUI(), i, touch.position, touch.tapCount);//Debug.Log(i + "---" + "touch.tapCount:" + touch.tapCount+ "---touch.position:"+ touch.position);}}}}}
