Question

我目前正在制作this game的愚蠢版本。

在游戏中，你的细胞越大，你应该越慢。
这应该是相称的。然而，在我的代码中，你可以看到我只是设置了一堆范围来使单元格以特定的速度运行。有没有办法实现比例速度/大小而不是设定范围？

这是我的代码。

pygame.init()
mainClock = pygame.time.Clock()

# set up the window
windowwidth = 800
windowheight = 600

pygame.display.set_caption('')

#bg = pygame.image.load("bg.png")
basicFont = pygame.font.SysFont('calibri', 36)

# set up the colors

# set up the cell and food data structure

for i in range(20):
    foods.append(pygame.Rect(random.randint(0, windowwidth - FOODSIZE), random.randint(0, windowheight - FOODSIZE), FOODSIZE, FOODSIZE))

# set up movement variables

# run the game loop

            # split the cell

    # draw the cell onto the surface
    cell = pygame.draw.circle(thesurface, playercolor, cell.center, size)

    # check if the cell has intersected with any food squares.
    for food in foods[:]:

            score+=1

    # draw the food

    # show the score

    thesurface.blit(printscore, (10, 550))

    # draw the window onto the thesurface

非常感谢帮助！

得分的一系列值如何，并使用divmod计算这个lsit的适当索引？

示例：

>>> speeds = range(50, 800, 50) >>> MOVESPEED, _ = divmod(130, 50) >>> MOVESPEED 2 >>> MOVESPEED, remainder = divmod(150, 50) >>> MOVESPEED 3
