无法将游戏对象添加到脚本中

Question

我为关卡菜单下载了一个脚本，但是当我尝试该脚本时，无法将滚动条分配给该脚本。我试图复制该脚本，然后再次粘贴并制作一个新脚本，但是它不起作用。我该如何解决？

using UnityEngine;
using UnityEngine.UI;

public class swipe_menu : MonoBehaviour
{
    public GameObject scrollbar;
    private float scrollpos = 0;
    float[] pos;
    void Start()
    {

    }
    void Update()
    {
        pos = new float[transform.childCount];
        float distance = 1f / (pos.Length - 1f);
        for (int i = 0; i < pos.Length; i++)
        {
            pos[i] = distance * i;
        }

        if (Input.GetMouseButton(0))
        {
            scrollpos = scrollbar.GetComponent<Scrollbar>().value;
        }
        else
        {
            for (int i = 0; i < pos.Length; i++)
            {
                if (scrollpos < pos[i] + (distance / 2) && scrollpos > pos[i] - (distance / 2))
                {
                    scrollbar.GetComponent<Scrollbar>().value = Mathf.Lerp(scrollbar.GetComponent<Scrollbar>().value, pos[i], 0.1f);
                }
            }
        }


        for (int i = 0; i < pos.Length; i++)
        {
            if (scrollpos < pos[i] + (distance / 2) && scrollpos > pos[i] - (distance / 2))
            {
                Debug.LogWarning("Current Selected Level" + i);
                transform.GetChild(i).localScale = Vector2.Lerp(transform.GetChild(i).localScale, new Vector2(1.2f, 1.2f), 0.1f);
                for (int j = 0; j < pos.Length; j++)
                {
                    if (j != i)
                    {
                        transform.GetChild(j).localScale = Vector2.Lerp(transform.GetChild(j).localScale, new Vector2(0.8f, 0.8f), 0.1f);
                    }
                }
            }
        }

    }

您将滚动条用作GameObject而不是Scrollbar，请尝试使用带有正确变量的likes，它将起作用。

没有很多地方可以找到如何使用滚动条，我能找到的最好的是https://forum.unity.com/threads/access-scrollbar-value-not-possible-through-code.283486/
