如何成功存储和加载游戏角色的数据？

Question

我编写了一个脚本，它结合了鲸鱼角色来创建一个新角色。但是，很难从新创建角色的名称、级别和位置列表中保存和加载数据。

玩游戏时似乎没有存储和加载鲸鱼数据。

如果你能告诉我哪里出了问题，我真的很感激。

您的代码实际上在设计方面被破坏了。

First PlayerPref 默认不支持布尔保存。

IsSave = PlayerPrefs.HasKey //this will always return false.

这就是为什么每次您开始游戏时，您保存的所有数据都会被删除。 你可以试试这个方法来保存和加载布尔类型How to save bool to PlayerPrefs Unity

现在，您究竟是如何决定在更新功能中保存和加载数据的？！ ，如果您的数据量很大，这很糟糕，并且会产生巨大的性能成本。你不能这样做。

相反，尝试制作存储数据并加载它的事件，例如一旦玩家进入触发框，数据就会被保存，当然如果保存了你不需要重新加载它，因为你必须加载保存后的数据？！！

再一次，不要一直这样在更新函数上读写，这是糟糕的设计。
