• Hello, 因此,我正在撰写一场有关青少年的游戏,我有这一方法“作用”,我内部有两处。 当我使用“返回”的方法退出该方法时,该方法一直得到执行。

• 以下是我守则的一部分。 我用“第#########################################”来记述的两条线。

• 因此,当这种条件“面值3=0&序列化?”是真实的,它应当停止方案,退出,然而,它又执行了“引诱”的方法,而且这一方法甚至不会停留在一旁。 谁能帮助我? 非常感谢。

I tried to add a "puts" after the condition "if count % 3 == 0 && serialize?" and it was not printed. And I also tried to reproduce the problem by making a simple class and method with loop and everything works fine. I use Vscode.
