通过 playerprefs 将难度设置转移到游戏场景

Question

感谢一些优秀的建议，我有难度按钮来改变我的游戏的刷新率。但是，这些变化并没有转化为后续场景。谁能发现我的 Playerprefs 设置的问题？

难度按钮脚本

私有Button按钮；

public RandomSpawn randomSpawn;

public int difficulty;


void Start()
{
    button = GetComponent<Button>(); 
    randomSpawn = GameObject.Find("Random Spawn").GetComponent<RandomSpawn>();
    button.onClick.AddListener(delegate{randomSpawn.UpdateSpawnRate(difficulty);});
}

void SetDifficulty()
{
    Debug.Log(gameObject.name + "was clicked");
}

 void Update()
{
    PlayerPrefs.SetInt("Player Difficulty", difficulty);
}

}

生成脚本

public GameObject prefab1, prefab2, prefab3, prefab4;

public float maxSpawnRate = 2f;

private float nextSpawn = 0f;

private int whatToSpawn;

private float spawnRate = 2f;

public static int difficulty = 0;

private void Start()
{
    difficulty = PlayerPrefs.GetInt("Player Difficulty");
}

void Update()
{
    
    if (Time.time > nextSpawn) { //if time has come
        whatToSpawn = Random.Range(1, 6); // define random value between 1 and 4 (5 is exclusive)
        Debug.Log(whatToSpawn); //display its value in console
   
   
        switch (whatToSpawn) {
            case 1:
                Instantiate(prefab1, transform.position, Quaternion.identity);
                break;
            case 2:
                Instantiate(prefab2, transform.position, Quaternion.identity);
                break;
            case 3:
                Instantiate(prefab3, transform.position, Quaternion.identity);
                break;
            case 4:
                Instantiate(prefab4, transform.position, Quaternion.identity);
                break;
       
        }
 
        nextSpawn = Time.time + spawnRate;
    }
}

public void UpdateSpawnRate(int difficulty)
{
    spawnRate = maxSpawnRate / difficulty;
}

}

SetDifficulty 没有显示为 Inspector 的 OnClick enter image description here 的选项

我认为问题在于在Update() 方法中使用SetInt，因为您有多个使用RandomSpawn 脚本的对象。它会随着每个对象的难度不断覆盖这个值。

private Button button;

public int difficulty;


void Start()
{
    button = GetComponent<Button>();

    // can also add the onclick to your button here
    button.onClick.AddListener(delegate{SetDifficulty();});
}

// make this your buttons onClick in the hierarchy
public void SetDifficulty()
{
    PlayerPrefs.SetInt("Player Difficulty", difficulty);
    Debug.Log(gameObject.name + "was clicked");
}
}

SetDifficulty 是按钮的 onClick 吗？如果是这样，如果您在检查器中分配 onClick，则不再需要 button.onClick.AddListener。我会将 PlayerPrefs.SetInt 移动到您的按钮发生 onClick 的任何位置，这样您就可以在该实例中设置难度，而不是在 Update() 中的每一帧。

我现在正在编辑 spawn 脚本以根据难度和 maxSpawn 更改 spawnRate；

public GameObject prefab1, prefab2, prefab3, prefab4;

public float maxSpawnRate = 2f;

private float nextSpawn = 0f;

private int whatToSpawn;

private float spawnRate = 2f;

public static int difficulty = 0;

private void Start()
{
    difficulty = PlayerPrefs.GetInt("Player Difficulty");
    spawnRate = maxSpawnRate / difficulty;
}

void Update()
{
    
    if (Time.time > nextSpawn) { //if time has come
        whatToSpawn = Random.Range(1, 6); // define random value between 1 and 4 (5 is exclusive)
        Debug.Log(whatToSpawn); //display its value in console
   
   
        switch (whatToSpawn) {
            case 1:
                Instantiate(prefab1, transform.position, Quaternion.identity);
                break;
            case 2:
                Instantiate(prefab2, transform.position, Quaternion.identity);
                break;
            case 3:
                Instantiate(prefab3, transform.position, Quaternion.identity);
                break;
            case 4:
                Instantiate(prefab4, transform.position, Quaternion.identity);
                break;
       
        }
 
        nextSpawn = Time.time + spawnRate;
    }
}
