我是 python 新手，所以如果我错误地命名了 pygame 对象，请原谅我。我的任务是构建一个虚拟弹球游戏机。当球从窗户落下时，我无法获得球的坐标。我需要坐标来跟踪分数并重置循环，以便用户可以在它触底后放下另一个球。
这是我的源代码。

这是我想添加该功能的特定代码：

if event.type == pygame.MOUSEBUTTONUP:
mouseX, mouseY = pygame.mouse.get_pos()
ticks = 0
#keep making new balls & pins
if ticks == 0:
step = 0
x_shift = 0
y_shift = 0
#Generate the new ball
mass = 1
inertia = pymunk.moment_for_circle(mass, 0, 14, (0, 0))
radius = 12
ball = pymunk.Body(mass, inertia)
#Keep the ball in bounds when user drops
if(mouseX < 25):
mouseX = 10
if(mouseX > 480):
mouseX = 490
ball.position = mouseX, dropHeight
shape = pymunk.Circle(ball, radius)
shape.collision_type = COLLTYPE_BALL
space.add(ball, shape)
balls.append(shape)
ticks = 50
pygame.draw.line(screen, (255,0,255), (20,60), (480,60), 2)

我想将球坐标打印到终端，以便添加得分和重新启动功能。我觉得我错过了一个非常简单的解决方案。
