Unity2D-当玩家被击中时如何在摧毁它们后恢复心脏

Question

我正在使用 Destroy(Corazones[0].gameObject);摧毁一个阵列中的 5 颗心，但我需要在玩家获得另一颗心时恢复它们。我已经有了增加生命 +1 的对撞机并且它可以工作，但我不知道如何重生代表生命的心。

当玩家被击中时，红心会被摧毁()；但我也需要用 Vida() 来恢复心脏；这增加了 live +1

感谢您的帮助！ This is the way the hearts look

我的代码使用了西班牙语单词。 PD：我知道我的代码一团糟，但适用于其他东西。

Answer 1

您可以使用 Corazones[0].gameObject.setActive(false) 或简单的 Corazones[0].setActive(false) 而不是使用 Destroy(Corazones[0].gameObject)，因为数组已经包含 GameObjects.

这将保留 GameObject，同时它的所有组件和子项都将被停用，包括它的 Renderer，这将使它消失。

然后当您需要它时，您可以使用 Corazones[0].setActive(true) 重新激活它。
