C# 统一：不能将滚动面板切换为垂直而不是水平？

好的，我发现C#中的Unity滚动面板有问题。我从这里下载了这个字符选择器，它由一个附加到滚动面板的脚本组成：

它工作得很好，但问题是我不能让它垂直滚动而不是水平滚动。我在实际的滚动面板上选中了“垂直”布尔值而不是水平值，然后在脚本中我将基于x值的位置更改为y值

我在哪里发表了评论，下面是脚本：

float[] distance;

    bool dragging = false;

    int minButtonNum;
    int currentSelectedPly = -1;

    public float objectScale = 1.7f;
    public int bttnDistance = 300;

    void OnEnable() {
        //txtGeneralCash.text = "" + PlayerPrefs.GetInt ("money", 0);
    }

    void Start(){
        distance = new float[prefab.Length];

        //instatiate the prefab
        for(int i=0; i<prefab.Length;i++){
            prefab[i] =  Instantiate(prefab[i],center.transform.position,camInUse.transform.rotation) as GameObject;
            prefab [i].transform.SetParent(panel.transform);
            Vector3 pos = prefab[i].GetComponent<RectTransform>().anchoredPosition;
            pos.x += (i * bttnDistance); //**CHANGED TO POS.Y
            prefab [i].GetComponent<RectTransform> ().anchoredPosition = pos; 
        }
    }

    void Update(){
        //calculate the relative distance
        for(int i=0;i<prefab.Length;i++){
            distance [i] = Mathf.Abs (center.transform.position.x - prefab [i].transform.position.x); //CHANGED THESE TO .Y
        }

        float minDistance = Mathf.Min (distance);

        // Aplly the scale to object
        for(int a=0;a<prefab.Length;a++){
            if (minDistance == distance [a]) {
                minButtonNum = a;

                //this is when each char is selected !!!!!!!!!!!!!!!
                if(minButtonNum != currentSelectedPly){
                    //lookAtPrice (minButtonNum);
                    scaleButtonCenter (minButtonNum);
