我正在使用 Arduino 为我的学校项目制作一个反应游戏，我想使用附加中断来注册我的按钮按下操作，但我所做的功能不会在我试图制作的附加中断语句中声明。这是我第一次使用基于对象的编程，所以我还没有完全习惯它的工作原理。
#include <Arduino.h>
// Game class
/**
* The Game class represents a reaction game that can be played between two players.
*
* The game starts when any button is pressed. The RGB LED will turn red for a random
* amount of time, and then turn green. The first player to press their button when the
* RGB LED turns green will win the round. The winner's indicator LED and the RGB LED will
* flash rapidly several times, and a fanfare will play from the buzzer. If a player presses
* their button before the RGB LED turns green, they will lose the round and their indicator
* LED and the RGB LED will flash rapidly several times, and a failure sound will play from
* the buzzer. The class takes in the pin numbers for the buttons, LEDs, RGB LED, and buzzer
* as parameters in the constructor. The class provides methods to start the game, blink the
* winner LED, blink the RGB LED, and randomize the lights.

我尝试在代码中移动函数来声明主题，但无论我把它们放在哪里，它们都会导致我的整个代码出现错误。我非常有信心这是因为附加中断在类中，但我不知道如何使其适合我的代码的其余部分。
除了 Juraj 提到的关于前向声明的内容。
您的类设计存在一些问题。
当 Arduino 启动时，其中有一个 main() 函数，该函数在将控制权传递给
setup()init()begin()setup()pinMode()begin()setup()其他参考：
