How to use Callback type in Python?

Coding
#1

Hello,

I made a python project which detect collision.

It works anyway now.

If camera go on the yellow circle, the girl dance.
but there is a error message on the edit screen.

Expected type ‘(BaseItem) → None’, got ‘(thing: {eq}) → None’ instead

What is a correct usage of this callback function type?

Could you give me a example code?

Oh, I found it.
It’s resolved.

Thanks,
