在Unity中,C#静态变量可以用于存储全局数据,这些数据在所有游戏对象之间共享。静态变量在Unity中的应用场景包括:
public class GameManager : MonoBehaviour
{
public static int deathCount;
void OnPlayerDeath()
{
deathCount++;
}
}
public class GameSettings : MonoBehaviour
{
public static float gameDifficulty;
public static float volume;
void Start()
{
gameDifficulty = PlayerPrefs.GetFloat("GameDifficulty", 1.0f);
volume = PlayerPrefs.GetFloat("Volume", 1.0f);
}
}
public class Singleton<T> : MonoBehaviour where T : MonoBehaviour
{
private static T _instance;
public static T Instance
{
get
{
if (_instance == null)
{
_instance = FindObjectOfType<T>();
if (_instance == null)
{
GameObject singletonObject = new GameObject();
_instance = singletonObject.AddComponent<T>();
singletonObject.name = typeof(T).ToString() + " (Singleton)";
}
}
return _instance;
}
}
}
public class SharedResources : MonoBehaviour
{
public static Font sharedFont;
public static Texture2D sharedTexture;
void Start()
{
sharedFont = Resources.Load<Font>("Fonts/SharedFont");
sharedTexture = Resources.Load<Texture2D>("Textures/SharedTexture");
}
}
注意:在使用静态变量时,要确保它们在游戏结束时不会导致内存泄漏。对于引用类型的静态变量,可以考虑使用弱引用(WeakReference)来避免内存泄漏。
