所以我正在制作一个游戏，玩家必须点击移动的矩形（网球）来获得积分。到目前为止，我已经创造了网球和其他一些球，我让它们在屏幕上随机移动并从边缘反弹。我还制作了一个叫做目标的矩形，用鼠标移动。我希望每次玩家点击网球（带目标）时，游戏都会增加10点，如果他们点击屏幕上的其他地方，就会扣除生命。任何帮助将不胜感激！ 谢谢:)）

答案 0 :(得分：0)
我建议不要创造一个球4次。相反，创建一个球类并制作4个球对象。试试这个
class ball:
def __init__(self, x, y, image, location):
self.x = x
self.y = y
self.img = image
self.movement = [x, y]
self.rect = self.img.get_rect()
self.rect.topleft = location
然后，你可以摆脱所有这些：
x= randint(20,40)
y= randint(20,40)
ball=pygame.image.load ('ball_t.png')
ball_movement=[x,y]#amount ball moves each time (x,y)
ball_location=[100,100]#x,y co-ordinates for start position
ball_rect=ball.get_rect()#gets rectangle for ball
x2= randint(5,15)... etc.
并将其替换为：
balls = []
balls.append(ball(randint(20, 40), randint(20, 40), 'ball_t.png', [100, 100])
balls.append(ball(randint(5, 15), randint(5, 15), 'ball_tt.png', [10, 10])
balls.append(ball(randint(10, 40), randint(10, 30), 'ball_b.png', [10, 100])
balls.append(ball(randint(10, 30), randint(10, 30), 'ball_bs.png', [200, 100])
然后，取这一部分：
if ball_rect.left<0 or ball_rect.right>screen_width: #check whether ball is off screen (x)
ball_movement[0]=-ball_movement[0]#change direction on x axis
if ball_rect.top<0 or ball_rect.bottom>screen_height: #check whether ball is off screen (y)
ball_movement[1]=-ball_movement[1] #change direction on y axis
if ball2... etc.
并用球的方法替换它。
class ball:
def __init__():
blah blah blah init
def is_touching_wall(self):
if self.rect.left < 0 or self.rect.right > screen_width:
self.movement[0] -= self.movement[0]
if self.rect.top < 0 or self.rect.bottom > screen_height:
self.movement[1] -= self.movement[1]
然后在主函数中：
for ball in balls:
ball.is_touching_wall()
然后，再向球类添加一个方法：
def update(self):
self.rect = self.rect.move(self.movement)
screen.blit(self.img, self.rect)
并替换此部分：
ball_rect=ball_rect.move(ball_movement)#move ball
ball2_rect=ball2_rect.move(ball2_movement)
ball3_rect=ball3_rect.move(ball3_movement)
ball4_rect=ball4_rect.move(ball4_movement)
screen.blit(ball, ball_rect)#redraws ball
screen.blit(ball2, ball2_rect)
screen.blit(ball3, ball3_rect)
screen.blit(ball4, ball4_rect)
用这个：
for ball in balls:
ball.update()
最后，还有两项建议。
不要在SE上发帖说“这是我的代码。修复它。”您从未指定尝试解决问题的方法，代码中的问题所在，或者甚至是您的问题。此外，尝试仅发布将复制问题的代码的最小部分。修复您的代码，并在您的问题中添加更多信息，然后人们将更愿意帮助您实现目标。
注意格式化。阅读PEP-8。在参数之间和比较之间添加空格。缩进更好。导入这个。等...
