Unity 用腳本給EventTrigger添加各類事件

using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.EventSystems; public class Trigger : MonoBehaviour { EventTrigger eventTrigger; // Start is called before the first frame update
    void Start() { eventTrigger = GetComponent<EventTrigger>(); AddPointerEnterEvent(); AddPointerExitEvent(); AddPointerClickEvent(); } void AddPointerEnterEvent() { EventTrigger.Entry entry = new EventTrigger.Entry(); entry.eventID = EventTriggerType.PointerEnter; entry.callback = new EventTrigger.TriggerEvent(); UnityEngine.Events.UnityAction<BaseEventData> callback = new UnityEngine.Events.UnityAction<BaseEventData>(PointerEnter); entry.callback.AddListener(callback); eventTrigger.triggers.Add(entry); Debug.Log("AddPointerEnterEvent"); } void AddPointerExitEvent() { EventTrigger.Entry entry = new EventTrigger.Entry(); entry.eventID = EventTriggerType.PointerExit; entry.callback = new EventTrigger.TriggerEvent(); UnityEngine.Events.UnityAction<BaseEventData> callback = new UnityEngine.Events.UnityAction<BaseEventData>(PointerExit); entry.callback.AddListener(callback); eventTrigger.triggers.Add(entry); Debug.Log("AddPointerExitEvent"); } void AddPointerClickEvent() { EventTrigger.Entry entry = new EventTrigger.Entry(); entry.eventID = EventTriggerType.PointerClick; entry.callback = new EventTrigger.TriggerEvent(); UnityEngine.Events.UnityAction<BaseEventData> callback = new UnityEngine.Events.UnityAction<BaseEventData>(PointerClick); entry.callback.AddListener(callback); eventTrigger.triggers.Add(entry); Debug.Log("AddPointerClickEvent"); } void PointerEnter(BaseEventData baseEventData) { Debug.Log("enter"); } void PointerExit(BaseEventData baseEventData) { Debug.Log("exit"); } void PointerClick(BaseEventData baseEventData) { Debug.Log("click"); } }
