Unity C＃PlayerPrefs /無法讓它工作

剛剛學習Unity/C＃並且在保存PlayerPrefs時遇到了一些大問題。我們需要使用它們，儘管它們從未被解釋過，並且我試圖通過在線來源進行工作的所有代碼迄今爲止都失敗了。請記住，我仍在學習，所有反饋將不勝感激！我試圖保存水平完成的時間（在所有事情都在舞臺上死亡之後），並使用playerpref設置函數保持單獨的高分。這裏是我到目前爲止的代碼：Unity C＃PlayerPrefs /無法讓它工作

using UnityEngine; 
using System.Collections; 

public class playerScript : MonoBehaviour { 

    public float currentHealth = 100;   // Player Hp 
    private float restartDelay = 5f;   // Time to wait before restarting the level 
    public float restartTimer;     // Timer to count up to restarting the level 
    public float thrust = 100f; 
    public Rigidbody rb; 
    private string textFieldString;    // Declaring a text field into a string 
    public bool isFinished;      // Checking if game has finished or not 
    public static float bestTime = PlayerPrefs.GetFloat ("HighScore", 0); 
    float gameTime; 



    // Use this for initialization 
    void Start() { 
     rb = GetComponent<Rigidbody>(); 
    } 

    // Update is called once per frame 
    void Update() { 
     gameTime += Time.deltaTime; 
     if(currentHealth <= 0) { 
      currentHealth = 0; 
      restartTimer += Time.deltaTime; 

      // .. if it reaches the restart delay... 
      if(restartTimer >= restartDelay) 
      { 
       // .. then reload the currently loaded level. 
       Application.LoadLevel(Application.loadedLevel); 
      } 
     } 
     //When all enemies are cured, calls this code 

     if(GameObject.FindGameObjectsWithTag("Enemy").Length==0) { 
      isFinished = true; 
      //Application.LoadLevel(Application.loadedLevel); 
     } 
     if (isFinished == true) { 

      bool isNewHighscore = false; 
      if (gameTime < bestTime) 
       { 
       PlayerPrefs.SetFloat ("HighScore", gameTime); 
       Debug.Log ("HighScoreSet"); 
       } 
       bestTime = PlayerPrefs.GetFloat("Best Time"); 
     } 
    } 

     void OnCollisionEnter(Collision collision) {  
      // Reduce health 
      if (collision.gameObject.tag == "Enemy") { 
         currentHealth -= collision.gameObject.GetComponent<ZombieBotAi>().zombieDamage; 
         rb.AddForce (transform.forward * thrust); 
       } 
     } 

    //Event for running into healing bottles 
    void OnTriggerEnter(Collider other){ 
     switch(other.gameObject.tag) 
     { 
      case "Heal": 
      ChangeHP(25); 
      break; 
     } 
     //Destroys healing bottle after collision 
     Destroy (other.gameObject); 
    } 
    //Displays Current HP on GUI 
    void OnGUI(){ 
     textFieldString = GUI.TextField (new Rect (35, 500, 140, 30),"HP\t: " + currentHealth.ToString()); 
     textFieldString = GUI.TextField (new Rect (800, 35, 140, 30),"Best Time\t: " + PlayerPrefs.GetFloat ("HighScore")); 
     if(GameObject.FindGameObjectsWithTag("Enemy").Length==0) { 
      textFieldString = GUI.TextField (new Rect (600, 300, 230, 30), "You have won the game in " + gameTime + " seconds!"); 
     } 
     if (currentHealth <= 0) { 
      textFieldString = GUI.TextField (new Rect (600, 300, 230, 30), "You have been infected! Game Over !!"); 
       } 
     } 
    //HP cant go above 100 
    void ChangeHP(float Change){ 
     currentHealth += Change; 
     if (currentHealth > 100) { 
      currentHealth=100; 
       } 

    } 

}

你沒有解釋你的問題。你有什麼問題？什麼不工作，你是否得到錯誤？ – Programmer

我沒有讀過你的代碼，因爲你沒有解釋問題是什麼。但是在爲PlayerPrefs設置一個值後，請記得調用PlayerPrefs.Save（），否則將不會保存。 – JeanLuc

問題是我有0線索需要什麼來獲得playerprefs保存，然後正確調用它來顯示高分，當我需要它。 –

你一定要修復這些行：

if (isFinished == true) { 

     bool isNewHighscore = false; 
     if (gameTime < bestTime) 
      { 
      PlayerPrefs.SetFloat ("HighScore", gameTime); 
      Debug.Log ("HighScoreSet"); 
      } 
      bestTime = PlayerPrefs.GetFloat("Best Time"); 
    }

PlayerPrefs不起作用這樣的，一開始你應該值賦給變量。你在這裏做這樣的：

PlayerPrefs.SetFloat ("HighScore", gameTime);

那麼你應該叫：

PlayerPrefs.Save();

，以節省您的變量，如果你要載入你拯救它，你應該使用相同的密鑰變量。

bestTime = PlayerPrefs.GetFloat("HighScore");

希望這是你在找什麼。
