Unity 鼠标悬停_unity鼠标停留出现属性

程序实现效果：

 using UnityEngine.EventSystems;

  void Update()
    {
        //鼠标按下的时候认为是退出状态
        if (Input.GetKey(KeyCode.Mouse0) || Input.GetKey(KeyCode.Mouse1))
        {
            //除了leftAlt键盘之外
            if (Input.GetKey(KeyCode.LeftControl))
            {
                return;
            }
            mouse_Hover_Exit(null);
        }
    }

    void Start()
    {
        WindowCtrl_Click();
    }


    private void WindowCtrl_Click()
    {
        //添加鼠标悬浮事件
        EventTrigger trigger = GetComponent<EventTrigger>();
        if (null == trigger)
        {
            trigger = gameObject.AddComponent<EventTrigger>();
        }
        //鼠标悬停进入
        EventTrigger.Entry hoverOnEntry = new EventTrigger.Entry();
        //如果时鼠标悬浮进入
        hoverOnEntry.eventID = EventTriggerType.PointerEnter;
        hoverOnEntry.callback.AddListener((data) => { mouse_Hover_On((PointerEventData)data); });
        trigger.triggers.Add(hoverOnEntry);

        //鼠标悬浮退出
        EventTrigger.Entry hoverExitentry = new EventTrigger.Entry();
        //如果时鼠标悬浮退出
        hoverExitentry.eventID = EventTriggerType.PointerExit;
        hoverExitentry.callback.AddListener((data) => { mouse_Hover_Exit((PointerEventData)data); });
        trigger.triggers.Add(hoverExitentry);

        //鼠标悬浮退出
        EventTrigger.Entry pressEntry = new EventTrigger.Entry();
        //如果时鼠标悬浮进入
        pressEntry.eventID = EventTriggerType.PointerDown;
        pressEntry.callback.AddListener(delegate { mouse_Press_Down(); });
        trigger.triggers.Add(pressEntry);
    }

    private void mouse_Press_Down()
    {

    }

    /// <summary>

    private void mouse_Hover_Exit(PointerEventData data)
    {
        this.gameObject.GetComponent<DOTweenAnimation>().DOPlayBackwards();
        this.gameObject.GetComponent<ImageFlashEffect_Drone>().UpdateParam(false);
    }

    /// <summary>
    /// 鼠标悬停进入

    /// <param name="data"></param>
    private void mouse_Hover_On(PointerEventData data)
    {
        this.gameObject.GetComponent<DOTweenAnimation>().DOPlayForward();
        this.gameObject.GetComponent<ImageFlashEffect_Drone>().UpdateParam(true);

解释一下： 本人写的是当鼠标悬停在该物体上时正序播放动画，离开时则倒序播放。可以根据需求修改mouse_Hover_Exit，mouse_Hover_On，mouse_Press_Down方法即可。
