U3d：eventertrigger的使用

public class Test3 : MonoBehaviour,IPointerEnterHandler,IPointerExitHandler
{
    // Start is called before the first frame update
    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {
        
    }

    public void OnPointerEnter(PointerEventData eventData)
    {
        print(eventData.clickTime+"enter");
    }

    public void OnPointerExit(PointerEventData eventData)
    {
        //throw new NotImplementedException();
        print(eventData.button+"exit");
    }



}

直接继承对应的接口即可
