一旦其图片属性更改，对象在错误的时间翻转

Question

在我的游戏中，我添加了一个暂停功能，如果您已成功实现此功能，则可让您更换枪支。还有一个称为“转身”的功能，它可以与玩家一起旋转枪支，问题是有时切换枪支时，枪支最终会朝着玩家的枪尖指向，如果您改变枪支，枪支会朝着玩家的方向倾斜。再次指向玩家

我尝试过让它在每次切换到另一把枪时自动翻转，但这没有用。我看到的一种模式是，一旦我更换枪支，它将是正确的方法，而当我再次更换它时，将是错误的方法。

我不是100％确切地确定我真正需要哪些代码，但是我认为这是其中的一部分。只是为了快速地说出所有认为这是我的全部代码的人。 这不是我的全部代码！

结果是，一旦玩家选择了一把新枪，它将在以前正确时翻转错误的方向，而在之前错误时翻转正确的方向。我想要尝试的是，一旦您获得一门新枪，它将自动更改为正确的方式。对于如何解决这个问题，我有一个小小的想法，但我不是100％确信它会起作用。我当时正在考虑添加一个布尔值，如果它是True，它将在您返回主循环之前快速翻转主炮。

在我们上面的图中，枪的朝向是右，但是游戏认为它的朝向是左。

然后，我进入状态栏/暂停屏幕，然后选择同一把枪。

一旦我去选择了同一把枪，它突然决定回到正确的位置。
