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!!

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()
