麻烦我拔出的球使球拍偏斜（使用碰撞点功能）

Question

import pygame

def main():

    pygame.init()
    pygame.display.set_mode((500, 400))
    pygame.display.set_caption('Pong')   
    w_surface = pygame.display.get_surface() 
    game = Game(w_surface)
    game.play()
    pygame.quit() 

class Ball:

    def __init__(self,color,center,radius,velocity,surface):

        self.color = color
        self.center = center
        self.radius = radius
        self.velocity = velocity
        self.surface = surface

    def draw(self):
        pygame.draw.circle(self.surface,self.color,self.center,self.radius)

    def move(self):

        self.center[0] = self.center[0] + (self.velocity[0])*2
        self.center[1] = self.center[1] + (self.velocity[1])
        size = self.surface.get_size() 
        for index in range(0,2):
            self.center[index] = self.center[index] + self.velocity[index]
            if self.center[index] < self.radius: 
                self.velocity[index] = -self.velocity[index] 
            if self.center[index]+ self.radius > size[index]:

        self.game_clock = pygame.time.Clock()
        self.frames_per_second = 60
        self.surface = surface
        self.bg_color = pygame.Color('black')
        self.score1 = 0
        self.dot1 = Ball(pygame.Color('white'),[250,200],5,[2,1],self.surface)
        self.right_paddle = [380,180],[10,50]
        self.left_paddle = [100,180],[10,50]

    def play(self):

        while self.close_clicked == False:  
            self.handle_events()
            self.draw()
            if self.continue_game == True:
                self.update()
                self.decide_continue()
            self.game_clock.tick(self.frames_per_second)  

    def handle_events(self):  
        events = pygame.event.get()
        for event in events:
            if event.type == pygame.QUIT:
                self.close_clicked = True  

    def draw(self):

        self.surface.fill(pygame.Color('black'))
        self.dot1.draw()
        pygame.draw.rect(self.surface,pygame.Color('white'),self.right_paddle)
        pygame.draw.rect(self.surface,pygame.Color('white'),self.left_paddle)
        self.draw_score1()
        #I keep getting an error saying that tuple object has no attribute to collide point?
        if self.left_paddle.collidepoint(self.center) and self.velocity[0] < 0:
            self.velocity[0] = - self.velocity[0]
        if self.right_paddle.collidepoint(self.center) and self.velocity[0] > 0:
            self.velocity[0] = - self.velocity[0]        
        pygame.display.update()

    def draw_score1(self):
        fg_color = pygame.Color('white')

        font = pygame.font.SysFont('',70)

        text_string = '' + str(self.score1)
        text_string2 = '' + str(self.score1)
        text_box = font.render(text_string,True,fg_color,self.bg_color)
        text_box2 = font.render(text_string2,True,fg_color,self.bg_color)

        location = (5,0)
        location2 = (470,0)

        self.surface.blit(text_box,location)  
        self.surface.blit(text_box2,location2)

    def update(self):

        self.dot1.move()

main()

我用Google搜索了很多东西，但是collidepoint函数上没有很多东西。在pygame中，它说它需要一个我完全理解的点（x，y），但是，我需要使用球的中心作为它的x，y，因此一旦游戏检测到球拍已经达到该点，然后它将使球偏斜。我在碰撞点出现一些错误的地方写了一条评论！

Answer 1

.collidepoint()是.collidepoint()的方法。当然，pygame.Rect和pygame.Rect必须分别是self.right_paddle对象。例如：

self.left_paddle

现在您可以在对象上使用pygame.Rect。例如：

class Game:

    def __init__(self,surface):

        # [...]        

        self.right_paddle = pygame.Rect(380,180,10,50)
        self.left_paddle  = pygame.Rect(100,180,10,50)
