如何修复此空闲汽车游戏脚本

Question

我正在尝试制作一款每个人都可以购买汽车的游戏（我将这些数据保存到玩家偏好设置）。所以我的游戏中有 9 条汽车轨迹，我正在尝试编写一些代码，这样当你按下按钮时，汽车和该汽车的轨迹就会显示出来。

当点击旁边的按钮时，它会保存该数据，因此当人们重新开始游戏时，他们仍然会打开汽车和小径，无需再次按下按钮。

这是我的代码：

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

public class GameManager : MonoBehaviour
{ 
    public Button[] TrailLevel; 
    public GameObject[] Cars, Trails;
    public Text text; 
    public int CurrentCarToSpawn = 0; 

    private void Start()
    { }

    private void FixedUpdate()
    {
        UpdateCar();
    }

    public void InstantiateCar()
    {
        TrailLevel[CurrentCarToSpawn].gameObject.active = false;
        MineLevel[CurrentCarToSpawn+1].interactable = true;
        PlayerPrefs.SetInt("TrailCountA", PlayerPrefs.GetInt("TrailCountA") + 1);
        PlayerPrefs.Save();
        CurrentCarToSpawn++;
        UpdateCar();
    }

    void UpdateCar()
    {
        int TrailCountA= PlayerPrefs.GetInt("TrailCountA", 1);
        for (int i = 0; i < TrailLevel.Length; i++)
        {
            if (i + 1 > TrailCountA)
            {
                 TrailLevel.interactable = false;
            }
            if (TrailLevel.interactable)
            {
                Trains[CurrentCarToSpawn].gameObject.active = true;
                Mines[CurrentCarToSpawn].gameObject.active = true;
            }
        }
        text.text = PlayerPrefs.GetInt("TrailCountA").ToString();
    }
}

从您的代码中可以看出，这是我的处理方式：

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

public class GameManager : MonoBehaviour
{ 
    public Button[] TrailLevel; 
    public GameObject[] Cars, Trails;
    public Text text; 
    public int CurrentCarToSpawn = 0; 

    private void Start()
    { 
        // Load the current car. ADDED
        CurrentCarToSpawn  = PlayerPrefs.getInt("savedSelection", 0);
        // Since we are loading the last selection, we need to call our
        // instantiation method so it can activate the appropriate 
        // GameObjects.
        InstantiateCar();
    }

    private void FixedUpdate()
    {
        UpdateCar();
    }

    public void InstantiateCar()
    {
        TrailLevel[CurrentCarToSpawn].gameObject.active = false;
        MineLevel[CurrentCarToSpawn+1].interactable = true;
        PlayerPrefs.SetInt("TrailCountA", PlayerPrefs.GetInt("TrailCountA") + 1);
        // Save that this is our current selection.
        PlayerPrefs.SetInt("savedSelection", CurrentCarToSpawn);             
        PlayerPrefs.Save();
        CurrentCarToSpawn++;
        UpdateCar();
    }

    void UpdateCar()
    {
        int TrailCountA= PlayerPrefs.GetInt("TrailCountA", 1);
        for (int i = 0; i < TrailLevel.Length; i++)
        {
            if (i + 1 > TrailCountA)
            {
                 TrailLevel.interactable = false;
            }
            if (TrailLevel.interactable)
            {
                Trains[CurrentCarToSpawn].gameObject.active = true;
                Mines[CurrentCarToSpawn].gameObject.active = true;
            }
        }
        text.text = PlayerPrefs.GetInt("TrailCountA").ToString();
    }
}
