Python 2.7.7 / Pygame - 卡在滚动随机图像(管状飞鸟)

标签: python pygame

我目前正在尝试制作一个pygame版本的flappy bird(比我想象的更复杂)并坚持使管道产生随机高度。任何人都可以帮我这个吗?为了使这个动画相同,我想在屏幕右边生成一些管道并将它们稍微删除一点。当我运行当前代码时,管道图像位于左上角的彼此顶部,不会移动。 (鸟虽然工作)

import pygame, random, sys

pygame.init()
icon = pygame.image.load('flappybirdicon.png')
pygame.display.set_icon(icon)
screen = pygame.display.set_mode([284, 512])
pygame.display.set_caption("Flappy Bird")
bg = pygame.image.load('flappybirdbackground.png')
bgrect = bg.get_rect()
clock = pygame.time.Clock()

pipex = 335

class Bird(pygame.sprite.Sprite):
    def __init__(self, image, x, y):
        pygame.sprite.Sprite.__init__(self)
        self.image = pygame.image.load(image)
        self.rect = self.image.get_rect()
        self.pos = [x, y]

class Pipe(pygame.sprite.Sprite):
    def __init__(self, image, height):
        pygame.sprite.Sprite.__init__(self)
        self.image = pygame.image.load(image)
        self.rect = self.image.get_rect()
        self.height = height
        self.pos = [pipex, height]

    def scroll(self):
        self.rect.move_ip(-3, 0)
        self.pos[0] -= 3
        self.rect.center = self.pos

def draw_pipes():
    pipe1_height = random.randint(115, screen.get_height())
    pipe1 = Pipe('flappybirdpipe.png', pipe1_height)
    pipe2_height = 397 - pipe1_height
    pipe2 = Pipe('flappybirdpipe2.png', pipe2_height)
    screen.blit(pipe1.image, pipe1.rect)
    screen.blit(pipe2.image, pipe2.rect)

bird = Bird('flappybirdbird.png', 142, 256)
draw_pipes()

while True:
    clock.tick(30)
    bird.pos[1] += 5
    bird.rect.center = bird.pos
    screen.blit(bg, bgrect)
    pipe1.scroll()
    pipe2.scroll()
    screen.blit(bird.image, bird.rect)
    pygame.display.flip()
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            sys.exit()
        elif event.type == pygame.KEYDOWN:
            if event.key == pygame.K_SPACE:
                bird.pos[1] -= 75
        elif event.type == pygame.MOUSEBUTTONDOWN:
            bird.pos[1] -= 75

我不熟悉PyGame,但看起来你并没有在任何地方为你的管道设置X坐标。您正在设置高度,但从不设置位置。

看起来你似乎并没有在任何地方保存管道数据,所以我想你的代码也会在每次调用draw_pipes()时创建/绘制新的管道,这看起来是每一帧。 / p>
