1.实现单击、双击、长按功能

using UnityEngine;
using UnityEngine.Events;
using UnityEngine.EventSystems;
public class ButtonControl_Click_Press_Double : MonoBehaviour, IPointerClickHandler, IPointerDownHandler, IPointerUpHandler, IPointerExitHandler
{public float pressDurationTime = 1;public bool responseOnceByPress = false;public float doubleClickIntervalTime = 0.5f;public UnityEvent onDoubleClick;public UnityEvent onPress;public UnityEvent onClick;private bool isDown = false;private bool isPress = false;private float downTime = 0;private float clickIntervalTime = 0;private int clickTimes = 0;void Update(){if (isDown){if (responseOnceByPress && isPress){return;}downTime += Time.deltaTime;if (downTime > pressDurationTime){isPress = true;onPress.Invoke();}}if (clickTimes >= 1){clickIntervalTime += Time.deltaTime;if (clickIntervalTime >= doubleClickIntervalTime){if (clickTimes >= 2){onDoubleClick.Invoke();}else{onClick.Invoke();}clickTimes = 0;clickIntervalTime = 0;}}}public void OnPointerDown(PointerEventData eventData){isDown = true;downTime = 0;}public void OnPointerUp(PointerEventData eventData){isDown = false;}public void OnPointerExit(PointerEventData eventData){isDown = false;isPress = false;}public void OnPointerClick(PointerEventData eventData){if (!isPress){//onClick.Invoke();clickTimes += 1;}elseisPress = false;}
}

2.使用

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class ButtonsControl_1 : MonoBehaviour
{ButtonControl_Click_Press_Double btn;void Start(){btn = GetComponent<ButtonControl_Click_Press_Double>();btn.onClick.AddListener(Click);btn.onPress.AddListener(Press);btn.onDoubleClick.AddListener(DoubleClick);}void Click(){Debug.Log("click");}void Press(){Debug.Log("press");}void DoubleClick(){Debug.Log("double click");}
}
