颜色不打印 - 连接 4

Question

我正在尝试使用 GUI 编写一个 connect 4 游戏，但是我无法在我点击的地方打印颜色，我已经打印了 space = 0 的颜色，我也得到了它当我单击 1 和 2 时，它们会打印到板的文本版本上，但是在图形版本上，我试图让颜色根据输入的玩家数量进行打印。任何帮助表示感谢。

单元格的顶部是 HEIGHT - r * SQUARESIZE - SQUARESIZE，单元格的中心是 HEIGHT - r * SQUARESIZE - SQUARESIZE // 2:

def draw_board(board):
    for c in range(COLUMN_COUNT):
        for r in range(ROW_COUNT):
            pygame.draw.rect(screen, BLUE, (c * SQUARESIZE, HEIGHT - r * SQUARESIZE - SQUARESIZE, SQUARESIZE, SQUARESIZE))
            pygame.draw.circle(screen, BLACK, (c* SQUARESIZE + SQUARESIZE // 2, HEIGHT - r * SQUARESIZE - SQUARESIZE // 2), RADIUS)

    for c in range(COLUMN_COUNT):
        for r in range(ROW_COUNT):
            if board[r][c] == 1:
                pygame.draw.circle(screen, GREEN, (c * SQUARESIZE + SQUARESIZE // 2, HEIGHT - r * SQUARESIZE - SQUARESIZE // 2), RADIUS)
            elif board[r][c] == 2:
                pygame.draw.circle(screen, YELLOW,(c * SQUARESIZE + SQUARESIZE // 2, HEIGHT - r * SQUARESIZE - SQUARESIZE // 2),RADIUS)

我建议在应用程序循环中连续绘制网格：

screen = pygame.display.set_mode(size)

clock = pygame.time.Clock()
while not game_over:
    clock.tick(60)
    screen.fill(0)
    draw_board(board)
    pygame.display.update()

    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            sys.exit()

        # [...]

典型的 PyGame 应用程序循环必须：

通过 pygame.event.pump() or pygame.event.get().
根据输入事件和时间（分别为帧）更新对象的游戏状态和位置
清除整个显示或绘制背景
绘制整个场景（blit 所有对象）
通过pygame.display.update() or pygame.display.flip()
限制每秒帧数以限制 CPU 使用

使用pygame.time.Clock控制每秒帧数，从而控制游戏速度。

方法tick() of a pygame.time.Clock object, delays the game in that way, that every iteration of the loop consumes the same period of time. See pygame.time.Clock.tick():

This method should be called once per frame.

这意味着循环：

clock = pygame.time.Clock()
run = True
while run:
   clock.tick(60)

每秒运行 60 次。

参见pygame.time.Clock.tick():

This method should be called once per frame. It will compute how many milliseconds have passed since the previous call.
