EventTrigger组件监听点击等事件

1、封装好方法：
private delegate void TriggerEventMehod( BaseEventData pd );
private void AddTriggersListener( GameObject obj, EventTriggerType eventTriggerType, TriggerEventMehod triggerEventMehod )
{
EventTrigger ET = obj.GetComponent();
if ( ET == null )
{
ET = obj.AddComponent();
}
if ( ET.triggers.Count == 0 )
{
ET.triggers = new List();
}

        UnityAction callBack = new UnityAction( triggerEventMehod );
        EventTrigger.Entry entry = new EventTrigger.Entry();
        entry.eventID = eventTriggerType;
        entry.callback.AddListener( callBack );

        ET.triggers.Add( entry );
    }

2、调用
AddTriggersListener(img.gameObject,EventTriggerType.PointerClick,MyFunction01);
void MyFunction01(BaseEventData data)
{
Debug.Log(“click event1”);
}
