问题描述
最小的工作示例：
x = pygame.draw.circle(screen, color, (x, y), radius, width)
x.center = (my_wanted_center_x, my_wanted_center_y)
然后，在更新显示之后，它总是显示在其原始位置。
也尝试过其他数字。
x.move()不起作用。
如何以最简单的方式移动任何绘制的图形？

您可以使用来存储对象的位置，在while循环中更新rect的属性（例如.x或.center ），然后在rect.center位置绘制圆或图像/表面。
import pygame as pg
pg.init()
screen = pg.display.set_mode((640, 480))
clock = pg.time.Clock()
BG_COLOR = pg.Color('gray12')
SIENNA = pg.Color('sienna1')
radius = 20
# This rect serves as the position of the circle and
# can be used for collision detection.
rect = pg.Rect(50, 200, radius, radius)
done = False
while not done:
for event in pg.event.get():
if event.type == pg.QUIT:
done = True
rect.x += 1 # Update the position of the rect.
screen.fill(BG_COLOR)
# Now draw the circle at the center of the rect.
pg.draw.circle(screen, SIENNA, rect.center, radius)
pg.display.flip()
clock.tick(30)
pg.quit()
