Unity长按按钮多次升级

方案一  事件接口 using UnityEngine; using UnityEngine.EventSystems; public class Test : MonoBehaviour,IPointerDownHandler,IPointerUpHandler,IPointerExitHandler { private float unitTime = 0.5f;//间隔时间 private bool startClick;//是否在按压按钮 private float recordTime = 0f;//记录时间 private void Update() { if (startClick) { recordTime += Time.deltaTime; if (recordTime >= unitTime) { Debug.Log("升级了"); recordTime = 0f; } } } public void OnPointerDown(PointerEventData eventData) { Debug.Log("按下"); startClick = true; } public void OnPointerUp(PointerEventData eventData) { Debug.Log("松开"); startClick = false; recordTime = 0f; } public void OnPointerExit(PointerEventData eventData) { Debug.Log("离开了"); startClick = false; recordTime = 0f; } }

方案二  EventTrigger using System.Collections.Generic; using UnityEngine; using UnityEngine.Events; using UnityEngine.EventSystems; public class Test : MonoBehaviour { public GameObject target; private float unitTime = 0.5f;//间隔时间 private bool startClick;//是否在按压按钮 private float recordTime = 0f;//记录时间 private void Start() { List<EventTrigger.Entry> entryList = new List<EventTrigger.Entry>(); //按下 entryList.Add(GetNewEntry(EventTriggerType.PointerDown, (data) => { Debug.Log("按下"); startClick = true; })); //松开按钮 entryList.Add(GetNewEntry(EventTriggerType.PointerUp, (data) => { Debug.Log("松开"); startClick = false; recordTime = 0f; })); //离开交互区 entryList.Add(GetNewEntry(EventTriggerType.PointerExit, (data) => { Debug.Log("离开了"); startClick = false; recordTime = 0f; })); EventTrigger trigger = target.AddComponent<EventTrigger> (); trigger.triggers.AddRange(entryList); } private void Update() { if (startClick) { recordTime += Time.deltaTime; if (recordTime >= unitTime) { Debug.Log("升级了"); recordTime = 0f; } } } public EventTrigger.Entry GetNewEntry(EventTriggerType type, UnityAction<BaseEventData> callback) { EventTrigger.Entry entry = new EventTrigger.Entry (); entry.eventID = type; entry.callback.AddListener(callback); return entry; } }
