其他:
坏计时器1+=5
索引=0
对于坏人中的坏人:

如果badguy[0]我建议将此代码放入函数中,以便更易于阅读。 您一直在寻找的产品线是:

badguy[0]-=7
将坏人向左移动7个像素。 为了便于配置,您可以在脚本顶部添加一个变量
BADGER_SPEED=7
并将行更改为:

badguy[0]-=BADGER_SPEED
獾在此处生成:

badguys.append([640, random.randint(50,430)])

这将在坏人列表中添加一个大小为2的新列表。这两个部分是獾的位置。

你能告诉我獾的位置是在哪里设置的吗?我已经很累了,但是什么也没发生,我想要它,这样獾就从空中而不是屏幕的左侧来。(试着改变他移动到
badguy[1]-=7的行和它们产生的位置。但这毫无意义,因为它们永远不会到达你。你是什么意思?我把它改成badguy[1]-=2我该如何改变它,使它来自空气?你能定义“来自空气”吗?
