我正在制作一个成就系统。我的游戏中有2个场景。第一个场景是我的主菜单，另一个场景是我的游戏场景。我在主菜单场景中设计并编码了成就系统，并在我的游戏场景中添加了一个EarnCanvas。 EarnCanvas将显示玩家已解锁的成就。
我的代码只允许我将成就链接到主菜单上的EarnCanvas.i需要帮助修改代码或链接两个场景，以便我可以在游戏中的EarnCanvas中实例化解锁成就预制件现场。目前，当玩家解锁成就时，EarnCanvas中没有实例化或显示预制件。

答案 0 :(得分：0)
您应该使用 DontDestroyOnLoad 方法，这是将游戏对象保留在场景更改上的简单方法，您只需将以下代码添加到AchievementManager即可。
void Awake ()
{
DontDestroyOnLoad (transform.gameObject);
}
您可以为任何不希望在更改场景时销毁的游戏对象添加此对象。
