Unity2D-当玩家被击中时如何在摧毁它们后恢复心

【中文标题】Unity2D-当玩家被击中时如何在摧毁它们后恢复心

【英文标题】：Unity2D-How to restore hearts after destroying them when Player gets hit

【发布时间】：2021-11-27 06:26:40

【问题描述】：

我正在使用 Destroy(Corazones[0].gameObject);摧毁一个阵列中的 5 个心，但是当玩家得到另一个心时我需要恢复它们。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脏。

当玩家获得 Hit() 时，心会被摧毁；但我也需要用 Vida() 恢复心灵；这增加了现场+1

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

我的代码使用西班牙语单词。 PD：我知道我的代码是一团糟，但可以用于其他的东西。

【参考方案1】：

您可以使用Corazones[0].gameObject.setActive(false) 或简单地使用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，而它的所有组件和子项都将被停用，包括它的Renderer，这将使其消失。

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