Unity-接口实现点击事件

public class EventSystem : MonoBehaviour, IPointerClickHandler, IPointerEnterHandler, IPointerExitHandler {
    public void OnPointerClick(PointerEventData eventData) {
        Debug.LogError("连续点击次数" + eventData.clickCount);
        Debug.LogError("进入游戏时间"+  eventData.clickTime);
        Debug.LogError("点击了物体");
    }

    public void OnPointerEnter(PointerEventData eventData) {
        Debug.LogError("鼠标进入");
        GetComponent<Image>().color = Color.green;
        transform.localScale = Vector3.one * 2;
    }

    public void OnPointerExit(PointerEventData eventData) {
        Debug.LogError("鼠标退出");
        GetComponent<Image>().color = Color.white;
        transform.localScale = Vector3.one;
    }
}
