侧面滚动背景(python)-无法100％工作 [英] side scrolling background (python) - not 100% working

问题描述

您好，我正在侧面滚动背景中放入我的游戏，这是我现在得到的内容:

Hi there i am working on a side scrolling abckground to put in my game, heres what ive got at the moment:

import pygame
import sys
import pygame.sprite as sprite

theClock = pygame.time.Clock()
background = pygame.image.load('space.jpg')
background_size = background.get_size()
background_rect = background.get_rect()
screen = pygame.display.set_mode(background_size)
w,h = background_size
x = 0
y = 0
x1 = 0
y1 = -h
running = True
while running:
    screen.blit(background,background_rect)
    pygame.display.update()
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
    y1 += 5
    y += 5
    screen.blit(background,(y,x))
    screen.blit(background,(y1,1))
    if y > h:
        y = -h
    if y1 > h:
        y1 = -h
    pygame.display.update()
    theClock.tick(25)
pygame.quit()

此刻，我得到一个闪烁的屏幕，其中运动图像向右移动，原始图像在其上平稳地闪烁，这将不胜感激-因为它对于我的A级计算课程a并已尝试实现一个功能使他很久以来就喜欢这款游戏....再次感谢您的帮助

推荐答案

我也在游戏"中也遇到了视差效果.我会向您建议: http://www.pygame.org/project-pyParallax -2623-.html

i struggled with a parallax effect in my 'game' as well. I would suggest this to you: http://www.pygame.org/project-pyParallax-2623-.html

下载该模块，并运行和反汇编该演示，这非常容易理解和复制. (提示:parallax.ParallaxSurface.add()方法具有第三个参数，您可以将其传递给该参数，它将为您适当地缩放图像.非常易于使用的模块.

download the module, and run and disassemble the demo, it is very easy to understand and replicate. (Hint: the parallax.ParallaxSurface.add() method has a third argument you can pass to it that will scale your image appropriately for you. Very Very easy to use module.
