Question

我是Unity新手，我正在尝试在Card堆栈中实现滑动手势，已经设法通过使用预制脚本编写脚本来创建堆栈，该堆栈是动态的，最多可以容纳220张卡。

问题是手势，当我从堆栈正面向左滑动时，该卡应从堆栈中取出，而另一张卡应添加到堆栈的背面，总共总共只能显示 4张卡。

代码段1 ，我在其中创建我的游戏对象并将其设置为有效/无效

public void SetCardNumber ()
{
    Positions = new Vector3[4];
    CardScales = new Vector3[4];
    Positions [0] = new Vector3 (Screen.width / 2, (Screen.height / 2) + 135f, 0f);
    Positions [1] = new Vector3 (Screen.width / 2, (Screen.height / 2) + 90f, 0f);
    Positions [2] = new Vector3 (Screen.width / 2, (Screen.height / 2) + 45f, 0f);
    Positions [3] = new Vector3 (Screen.width / 2, Screen.height / 2, 0f);

    CardScales [0] = new Vector3 (0.85f, 0.85f, 0f);
    CardScales [1] = new Vector3 (0.9f, 0.9f, 0f);
    CardScales [2] = new Vector3 (0.95f, 0.95f, 0f);
    CardScales [3] = new Vector3 (1f, 1f, 0f);

    InActivePositions = new Vector3 (0f, 0f, 0f);
    InActiveCardScales = new Vector3 (1f, 1f, 0f);

    Cards = new GameObject[words.Length];
    CardNumber = new GameObject[words.Length];
    CardText = new GameObject[words.Length];
    ShowSentenceBulb = new GameObject[words.Length];
    for (int i = 0, j = words.Length; i <= words.Length - 1; i++,j--) {
        GameObject obj = (GameObject)Instantiate (CardPrefab) as GameObject;
        Cards [i] = obj;
        CurrentCardCounter++;

        Cards [i].transform.SetParent (panel.transform, false);
        foreach (Transform child in obj.transform) {
            if (child.tag == "TextCardNumber")
                CardNumber [i] = child.gameObject;
            if (child.tag == "TextCard")
                CardText [i] = child.gameObject;
            if (child.tag == "ShowSentenceBulb")
                ShowSentenceBulb [i] = child.gameObject;
        }

        if (i == 0) {
            CardText [i].GetComponent<Text> ().text = CurrentWordList [j - 1];
            CardText [i].GetComponent<Text> ().fontSize = 70;
            CardText [i].GetComponent<Text> ().color = new Color (255, 215, 0);
        } else
            CardText [i].GetComponent<Text> ().text = CurrentWordList [j - 1];
        CardNumber [i].GetComponent<Text> ().text = j + "";
        ShowSentenceBulb [i].GetComponent<Button> ().onClick.AddListener (ShowSentenceOnBulbClick);
    }

    var quotient = CurrentCardCounter / 4;

    for (int k = 3; CurrentCardCounter > 0; CurrentCardCounter--,k--) {
        if (CurrentCardCounter <= (4 * (quotient - 1))) {
            Cards [CurrentCardCounter - 1].SetActive (false);
        }
        else {
            Cards [CurrentCardCounter-1].transform.position = Positions [k];
            Cards [CurrentCardCounter-1].transform.localScale = CardScales [k];
            Cards [CurrentCardCounter-1].SetActive (true);
        }

    }
    CurrentCardCounter=words.Length-1;
    swipeAnim= Cards[CurrentCardCounter].GetComponent<Animator>();
}

我处理此问题的方式是在场景开始时创建所有gameObject，但仅使4个处于活动状态，每当我向左滑动时，都会将一张新卡设置为“活动”。

代码段2 ：向左滑动手势从堆栈中移除正面卡

if (swipeLeft && CurrentCardCounter > 0 && !isCardShowingSentence) {

        swipeAnim.enabled = true;
        swipeAnim.Play ("swipe");
        if (CurrentCardCounter > 0) {
            CurrentCardCounter--;
            swipeAnim = Cards [CurrentCardCounter].GetComponent<Animator> ();

            if (CurrentCardCounter > 3) {
                Cards [CurrentCardCounter].transform.position = Positions [3];
                Cards [CurrentCardCounter].transform.localScale = CardScales [3];
                Cards [CurrentCardCounter - 1].transform.position = Positions [2];
                Cards [CurrentCardCounter - 1].transform.localScale = CardScales [2];
                Cards [CurrentCardCounter - 2].transform.position = Positions [1];
                Cards [CurrentCardCounter - 2].transform.localScale = CardScales [1];
                Cards [CurrentCardCounter - 3].SetActive (true);
                Cards [CurrentCardCounter - 3].transform.position = Positions [0];
                Cards [CurrentCardCounter - 3].transform.localScale = CardScales [0];
            } else if (CurrentCardCounter > 2) {
                Cards [CurrentCardCounter].transform.position = Positions [3];
                Cards [CurrentCardCounter].transform.localScale = CardScales [3];
                Cards [CurrentCardCounter - 1].transform.position = Positions [2];
                Cards [CurrentCardCounter - 1].transform.localScale = CardScales [2];
                Cards [CurrentCardCounter - 2].transform.position = Positions [1];
                Cards [CurrentCardCounter - 2].transform.localScale = CardScales [1];
                Cards [CurrentCardCounter - 3].SetActive (true);
                Cards [CurrentCardCounter - 3].transform.position = Positions [0];
                Cards [CurrentCardCounter - 3].transform.localScale = CardScales [0];
            } else if (CurrentCardCounter > 1) {
                Cards [CurrentCardCounter].transform.position = Positions [3];
                Cards [CurrentCardCounter].transform.localScale = CardScales [3];
                Cards [CurrentCardCounter - 1].transform.localScale = CardScales [2];
                Cards [CurrentCardCounter - 1].transform.position = Positions [2];
                Cards [CurrentCardCounter - 2].transform.localScale = CardScales [1];
                Cards [CurrentCardCounter - 2].transform.position = Positions [1];
            } else if (CurrentCardCounter > 0) {
                Cards [CurrentCardCounter].transform.localScale = CardScales [3];
                Cards [CurrentCardCounter].transform.position = Positions [3];
                Cards [CurrentCardCounter - 1].transform.localScale = CardScales [2];
                Cards [CurrentCardCounter - 1].transform.position = Positions [2];
            }
        } else {
            //swipeAnim = Cards [0].GetComponent<Animator> ();
            //swipeAnim.enabled = true;
            //swipeAnim.Play ("shake");
            //swipeAnim.enabled = false;
        }

    }

这一切都得到了很好的处理，但是还有一个正确的滑动手势（要取回被刷过的卡，将被刷过的卡添加到堆栈的正面，然后将添加到背面的卡再次设为无效）弄乱了游戏对象的位置，我不知道为什么。

代码段3 ：向右滑动手势可将刷回的卡取回并从堆栈中取出背面的卡

if (swipeRight && CurrentCardCounter < words.Length - 1  && !isCardShowingSentence) {

        if (CurrentCardCounter < words.Length) {
            swipeAnim = Cards [CurrentCardCounter+1].GetComponent<Animator> ();
            swipeAnim.enabled = true;
            swipeAnim.Play ("swipeBack");
            CurrentCardCounter++;
        }

        if (CurrentCardCounter > 6) {
            Cards [CurrentCardCounter - 1].transform.position = Positions[3];
            Cards [CurrentCardCounter - 1].transform.localScale = CardScales[3];
            Cards [CurrentCardCounter - 2].transform.position = Positions[2];
            Cards [CurrentCardCounter - 2].transform.localScale = CardScales[2];
            Cards [CurrentCardCounter - 3].transform.position = Positions[1];
            Cards [CurrentCardCounter - 3].transform.localScale = CardScales[1];
            Cards [CurrentCardCounter - 4].SetActive (false);
            Cards [CurrentCardCounter - 4].transform.position = InActivePositions;
            Cards [CurrentCardCounter - 4].transform.localScale = InActiveCardScales;
        }else if (CurrentCardCounter > 5) {
            Cards [CurrentCardCounter - 1].transform.position = Positions[3];
            Cards [CurrentCardCounter - 1].transform.localScale = CardScales[3];
            Cards [CurrentCardCounter - 2].transform.position = Positions[2];
            Cards [CurrentCardCounter - 2].transform.localScale = CardScales[2];
            Cards [CurrentCardCounter - 3].transform.position = Positions[1];

            Cards [CurrentCardCounter - 4].SetActive (false);
            Cards [CurrentCardCounter - 4].transform.position = InActivePositions;
            Cards [CurrentCardCounter - 4].transform.localScale = InActiveCardScales;
        } else if (CurrentCardCounter > 2) {
            Cards [CurrentCardCounter - 1].transform.position = Positions[3];
            Cards [CurrentCardCounter - 1].transform.localScale = CardScales[3];

这个问题让我头疼，我不知道要多长时间，任何帮助将不胜感激
