PlayerPrefs
将数据存储到本地或对存储到本地的数据进行读取。

| public static void DeleteKey(string key); | Removes key and its corresponding value from the preferences. | 移除键及其对应值。 |
| public static float GetFloat(string key, [DefaultValue("0.0F")] float defaultValue); | Returns the value corresponding to key in the preference file if it exists. | 返回key对应的值(如果存在)。 |
| public static float GetFloat(string key); | ||
| public static int GetInt(string key, [DefaultValue("0")] int defaultValue); | ||
| public static int GetInt(string key); | ||
| public static string GetString(string key, [DefaultValue("\"\"")] string defaultValue); | ||
| public static string GetString(string key); | ||
| public static bool HasKey(string key); | Returns true if key exists in the preferences. | 如果键存在，则返回true。 |
| public static void Save(); | Writes all modified preferences to disk. | 将所有修改后的数据写入磁盘。 |
| public static void SetFloat(string key, float value); | Sets the value of the preference identified by key. | 设置key标识的数据的值。 |
