python - Pygame 暂停功能

问题描述

我一直在尝试为我的乒乓球游戏添加暂停功能，但它不起作用。我可以暂停游戏一次然后它停止，但之后如果我按下暂停游戏的键，游戏将移动几帧然后停止。之后，我必须按住暂停按钮才能使游戏移动。我将链接下面的类代码：

class Game:
    def __init__(self, start):
        self.start = start
        self.score1 = 0
        self.score2 = 0
        self.pause = False
        self.over = False

    def play(self, ai):
        player2.AI = ai
        screen = pygame.display.set_mode(size)
        pygame.display.set_caption("Pong")
        self.over = False
        while self.start:
            # quits if x is pressed
            for event in pygame.event.get():
                if event.type == pygame.QUIT:
                    pygame.quit()
                    exit()
            pressed_keys = pygame.key.get_pressed()
            if pressed_keys[pygame.K_p]:
                self.pauseMenu()
            if self.pause == False:
                # creates list of pressed keys and using that to determine movement
                pressed_keys = pygame.key.get_pressed()
                if pressed_keys[pygame.K_w]:
                    player1.moveUp(5)
                if pressed_keys[pygame.K_s]:
                    player1.moveDown(5)
                if player2.AI == True:
                    player2.AI_move(ball)
                if pressed_keys[pygame.K_SPACE]:
                    pygame.quit()
                else:
                    if pressed_keys[pygame.K_UP]:
                        player2.moveUp(5)
                    if pressed_keys[pygame.K_DOWN]:
                        player2.moveDown(5)

                if pressed_keys[pygame.K_p]:
                    self.pauseMenu()

                # scoring system if ball touches variable, increments score and resets ball to middle
                if ball.rect.x >= 790:
                    self.score1 += 1
                    ball.rect.x = 400
                    ball.rect.y = 240
                    ball.x_velo = choice([-2, 2])
                    ball.y_velo = choice([-1, -2, 1, 2])
                if ball.rect.x <= 0:
                    self.score2 += 1
                    ball.rect.x = 400
                    ball.rect.y = 240
                    ball.x_velo = choice([-2, 2])
                    ball.y_velo = choice([-1, -2, 1, 2])

                # bounces ball of top or bottom wall
                if ball.rect.y > 470 or ball.rect.y < 0:
                    ball.y_velo = -ball.y_velo

                # detects collision and reflects ball off board
                if pygame.sprite.collide_mask(ball, player1) or pygame.sprite.collide_mask(ball, player2):
                    ball.bounce()

                # refresh method to move ball
                ball.refresh()
                # draws background and sprites onto screen each tick
                screen.fill(BLACK)
                pygame.draw.line(screen, WHITE, [400, 0], [400, 580], 1)
                all_sprites_list.update()
                all_sprites_list.draw(screen)

                # draws score at top
                font = pygame.font.Font('ARCADECLASSIC.TTF', 74)
                text = font.render(str(self.score1), 1, BLUE)
                screen.blit(text, (300, 10))
                text = font.render(str(self.score2), 1, BLUE)
                screen.blit(text, (470, 10))
                if self.score1 >= 5:
                    self.victory("Player 1")
                elif self.score2 >= 5:
                    self.victory("Player 2")
                # refreshes display each tick
                pygame.display.flip()
                # sets number of ticks per second
                clock.tick(60)

    def victory(self, winner):
        pass

    def pauseMenu(self):
        if self.pause == True:
            self.pause = False
        elif self.pause == False:
            self.pause = True

解决方案

你可以试试这个：

pause=False
#your game code
for event in pygame.event.get():
    if event.type==KEYUP:
            if event.key==K_p:
                pause = True

while pause == True:
        for event in pygame.event.get():
            if event.type==KEYUP:
                if event.key==K_p:
                    pause = False

#your remaining code

您首先将暂停设为假，然后添加一个暂停屏幕的键。
