在实用程序类中，我将游戏状态称为 maingame2 函数，因此它会将级别更改为可用的下一个级别，是我在这里缺少代码还是误解了某些东西，因为我很困惑它也没有显示错误消息我做的事情当您再次按下播放按钮时，会看到 maingame2 函数被立即调用，但随后又返回到第一阶段（主游戏），不确定它是否与循环一起使用
答案 0 :(得分：1)
您需要设置 game_state.main_game2()，而不是递归调用 game_state.state == 'main_game2'：
class Utility():
# [...]
def draw(self):
text = font.render("Length: " + str(snake.length),True,BLACK)
text_y = text.get_rect().height
if start <= 0:
snake.alive = False
if (str(snake.length)) == '3':
snake_win()
if button.clickButton((size[0] / 2) - 75,25,150,50,GREEN,DGREEN,font,"You won!",WHITE,snake_win):
snake.reset()
food.reset()
game_state.state = 'main_game2'
