问题描述

我一直在尝试使此代码正常工作数周,无法解决问题.我有一个图像列表,我正在使用这些图像来动画角色.这款游戏起初运行良好,但是自从我设置背景动画(开始从左向右移动)以来,我的角色就​​停止出现了.我是否需要更改某些代码的位置?真的很困惑.谢谢!!

I have been trying to get this code to work for weeks and cannot figure out the issue. I have a list of images, that I am using to animate my character. THe game worked fine at first, but ever since I made the background animate (start moving left to right), my character stopped appearing. Do I have to change the location of some of my code? Really confused. Thank you!!

推荐答案

您在先前的一个问题中遇到了疑问-请参阅 https://stackoverflow.com/a/59761318/1832058

You get anwser in one of previous questions - see https://stackoverflow.com/a/59761318/1832058

您必须绘制man 之后 background.

def redrawGameWindow():

    # background images for right to left moving screen
    screen.blit(background, (backgroundX, 0))
    screen.blit(background, (backgroundX2, 0))

    # AFTER BACKGROUND !!!!
    man.draw(screen)

    pygame.display.update()
