这段代码有两个 `Start()` 函数，这会导致编译错误。你需要将它们合并成一个函数。你可以将第二个 `Start()` 函数中的内容移动到第一个 `Start()` 函数中，像这样：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

public class Duihua : MonoBehaviour
{
    public Text Duihuakuang;//对话框文本

    public Text Button1_text;
    public Text Button2_text;
    public Text Button3_text;

    public GameObject Button1;
    public GameObject Button2;
    public GameObject Button3;
    public GameObject Buttonjixu;
    public GameObject shurukuang;//输入框显示
    public InputField shuru_text;//输入框文
    public GameObject LiHui;//立绘底板
    public Sprite Sanjiao;//两个图片
    public Sprite Lutou;
    public int AA = 0;//大进度
    public int n = 0;//小进度
    public int anniu = 0;//按钮选项

    public Jueseshuxing Shuxin;

    void Start()
    {
        Duihuakuang = GetComponent<Text>();
        Button3 = GameObject.Find("Button3");
        Button3_text = Button3.GetComponentInChildren<Text>();
    }

    void updateButton3Text(string newText)
    {
        Button3_text.text = newText;
    }

    public void Xuanze1_Button()
    {
        Button1.SetActive(false);
        Button2.SetActive(false);
        Button3.SetActive(false);
        Buttonjixu.SetActive(true);
        anniu = 1;
        duihua(AA);
    }

    public void Xuanze2_Button()
    {
        Button1.SetActive(false);
        Button2.SetActive(false);
        Button3.SetActive(false);
        Buttonjixu.SetActive(true);
        anniu = 2;
        duihua(AA);
    }

    public void Xuanze3_Button()
    {
        Button1.SetActive(false);
        Button2.SetActive(false);
        Button3.SetActive(false);
        Buttonjixu.SetActive(true);
        anniu = 3;
        duihua(AA);
    }

    public void Continue_Button()
    {
        duihua(AA);
    }

    void duihua(int aa)
    {
        // TODO: 实现对话逻辑
    }
}

在这个例子中，我们将第二个 `Start()` 函数中的内容移动到了第一个 `Start()` 函数中，同时保留了第二个函数中的 `updateButton3Text()` 函数。这样就避免了编译错误。
