Unity简单实现斗地主滑动取牌效果（二）

脚本有两个：
1.管理脚本

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using DG.Tweening;

public class SelectManager : MonoBehaviour {

    public static SelectManager Instance;
    private void  Awake()
    {
        Instance = this;
    }

    List<Transform> cardList = new List<Transform>();

    private float initYValue = -100;
    private float outYValue = -70;
    private bool isHold=false;

    void Start () {
        cardList = new List<Transform>();
        isHold = false;
        cardList.Clear();
    }
	
	void Update () {
        if (Input.GetKeyDown(KeyCode.Mouse0))
        {
            isHold = true;
        }
        if(Input.GetKeyUp(KeyCode.Mouse0))
        {
            isHold = false;
            MouseEnterCard();
            cardList.Clear();
        }
	}

    public void SmoothAddCards(Transform cardTrans)            //滑入
    {
        if(isHold)
        {
            if (!cardList.Contains(cardTrans))
            {
                cardList.Add(cardTrans);
                cardTrans.GetComponent<CardMove>().SetBlack(true);
            }
            else
            {
                cardList.Remove(cardTrans);
                cardTrans.GetComponent<CardMove>().SetBlack(false);
            }
        } 
    }

    public void ClickAddCards(Transform cardTrans)             //点入(可重载，多态)
    {
        cardList.Add(cardTrans);
    }

    private void MouseEnterCard()
    {
        for (int i = 0; i < cardList.Count; i++)
        {
            float endValue = cardList[i].localPosition.y == initYValue ? outYValue : initYValue;
            cardList[i].DOLocalMoveY(endValue, 0.3f);
            cardList[i].GetComponent<CardMove>().SetBlack(false);
        }
    }
}

2.牌

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.EventSystems;

public class CardMove : MonoBehaviour ,IPointerEnterHandler,IPointerDownHandler{

    Transform blackGo = null;

    private void Start()
    {
        blackGo = transform.GetChild(1);
    }
    public void OnPointerDown(PointerEventData eventData)
    {
        SelectManager.Instance.ClickAddCards(this.transform);
    }

    public void OnPointerEnter(PointerEventData eventData)
    {
        SelectManager.Instance.SmoothAddCards(this.transform);
    }

    public void SetBlack(bool isblack)
    {
        blackGo.gameObject.SetActive(isblack);
    }
}
