Question

我写了一个由圆圈组成的代码。检查碰撞对墙壁的影响。但圆圈运动不正常。我使用rect的碰撞功能检查了碰撞。关于圆圈运动不正确的任何想法？有些圆圈正在移动，但当它们击中另一个圆圈时，它会粘在那个圆圈上并一起移动。这是我的代码

                pygame.quit(); sys.exit();
    clock.tick(100)
   # myrob.update()
    while(len(robolist) < pop):
        robolist.append(robot(colors[random.randrange(0,len(colors))],random.randrange(radiusUL+1,screensize[0]-radiusUL-1),random.randrange(radiusUL+1,screensize[1]-radiusUL-1),random.randrange(radiusLL,radiusUL),3,random.randrange(0,360)))
        idindex+=1
    screen.fill(white)
    for i in robolist:
        i.draw()
        i.update()

    #myrob.draw()
    pygame.display.update()

使用colliderect时python pygame碰撞错误
