我想通过给它更小的 y 和 x 变化来减慢圆的运动，如下所示：if event.key == pygame.K_DOWN: circleYchange = 0 circleXchange = 0 circleYchange += 0.5 if event.key == pygame.K_RIGHT: circleYchange = 0 circleXchange = 0 circleXchange += 0.5然后将其添加到circleY和circleX中，并绘制圆：circleX += circleXchangecircleY += circleYchangepygame.draw.circle(screen, (0, 0, 0), (circleX, circleY), size)但它给了我这种错误：TypeError: integer argument expected, got float如何减慢运动速度？

的中心参数pygame.draw.circle()必须是具有 2 个整数组件的元组。您必须将round坐标转换为整数值：
pygame.draw.circle(screen, (0, 0, 0), (round(circleX), round(circleY)), size)
