Question

我的课程代码有问题。我一直收到这个错误：TypeError：＆＃39;方法＆＃39;对象不可订阅，我不知道在哪里更改内容或更改内容。它显示了我在最后的颜色foor foodPass的行上的错误。我不知道问题是在那里还是我宣布foodPass

Answer 1

这只是一个小错字，你声明foodPos。它应该是：

   foodPos = foodSpawner.spawnFood()

Answer 2

当调用函数spawnFood时，您会缺少括号。

foodPos = foodSpawner.spawnFood

应该是：

foodPos = foodSpawner.spawnFood()
