Python pgzrun游戏开发遇AttributeError: 'list'无'x'属性报错求助

你遇到的AttributeError: 'list' object has no attribute 'x'是代码中多处变量名拼写、命名冲突问题导致的，具体问题和修复方案如下：

核心错误原因 #

create_impostors函数中，你将生成的单个Actor对象追加到列表时，写错了变量名：

# 错误写法
new_impostors.append(impostors)
# 正确写法
new_impostors.append(impostor)

这里impostors是你定义的全局空列表，导致new_impostors里的元素都是列表而非单个Actor对象，后续在layout_impostors中遍历修改x属性时，自然会报列表没有x属性的错误。

其他需要修复的错误 #

• 动画函数名拼写不一致：定义的函数名为animation_impostors，但在make_impostors中调用的是animate_impostors，二者需要统一为相同名称。
• 全局动画列表变量名错误：初始定义的是animation = []，后续代码全部使用复数animations操作，需要将初始定义改为animations = []。
• 动画创建时函数名写错：pgzero内置的动画创建函数是animate，不是animation，同时要避免变量名和函数重名。
• 鼠标点击事件中循环变量覆盖全局列表：for impostors in impostors会把全局的impostors列表覆盖，循环变量改为单数impostor即可。
