使用 PlayerPrefs 高分 Unity3D

Question

我一直在尝试使用 PlayerPrefs 制作最佳时间高分系统，我查看了很多资源，但不确定我做错了什么。 Bellow 是我的脚本，其中包含我最好的时间高分尝试，我已经评论了我试图用我的脚本做的所有事情以及需要做的事情或我认为可能不起作用的事情。

我不确定的所有区域都标记了 TODO：不确定我是否正确执行了此操作。

对于方法：

• public bool hasBestTime()：我需要检查我是否有最好的时间存储为高分

• float GetBestTime()：我需要获取当前高分（最佳时间）并返回当前高分

• public void PlayerWin()：我需要读取read并存储高分（最佳时间）

  using UnityEngine;
  
  using System.Collections;
  
  public class GameController : MonoBehaviour
  {
      public static readonly string OUT_OF_FUEL_MESSAGE = "Out of fuel!";
      public static readonly string WIN_MESSAGE = "Goal collect! You win!";
  
      public static GameController Instance { get; private set; }
  
      private bool gameOver = false; //A flag to store when the game is over
      private int goalsRemaining = 0; //the number of goals that are remaining in the level
      private float gameTime = 0; //the time (in seconds) that the player has been playing the level
  
      void Awake()
      {
          UIController.LoadUI();
          Instance = this;

Answer 1

public void PlayerWin()
    {
        gameOver = true;

        //Update the highscore
        float bestTime = 0;
        bool isNewHighscore = false;

        if (gameTime < PlayerPrefs.GetFloat("Best Time"))
        {
            PlayerPrefs.SetFloat("Best Time", gameTime);
        }
        //TODO: Not sure if I have done this correct trying to complete the code to read and store the highscore

        bestTime = PlayerPrefs.GetFloat("Best Time"); // ADD THIS LINE HERE

        //Pop up the win message
        UIController.GameOver(WIN_MESSAGE, gameTime, bestTime, isNewHighscore);
    }

在您检查实际时间是否为高分之后，但在显示它之前设置您最好的时间。
