我正在制作http://agar.io的版本，我正在尝试为玩家制作圆圈形状。我一直试图用pygame.draw.circle来绘制它，但它一直显示正方形。谢谢你的帮助！

答案 0 :(得分：2)
使用pygame.draw.circle代替pygame.draw.rect：
# draw the player onto the surface
pygame.draw.circle(screen, WHITE, player.center, 40)
您正在创建player对象：
player = pygame.draw.circle(screen, WHITE, (60, 250), 40)
pygame.draw.circle返回一个Rect对象（不是您可能期望的圆形对象），您可以使用其.center属性作为圆的中心。
