public class IPointer_Handler_Test : MonoBehaviour, IPointerEnterHandler, IPointerExitHandler
{
    public GameObject obj;
    /// <summary>

    /// </summary>
    /// <param name="eventData"></param>
    public void OnPointerEnter(PointerEventData eventData)
    {
        obj.SetActive(true);
    }
    /// <summary>

    /// </summary>
    /// <param name="eventData"></param>
    public void OnPointerExit(PointerEventData eventData)
    {
