fixes #4

Thanks for the PR.
I wonder how Godot treats static variables, I would expect that we can get them somehow (Maybe with ClassDB?).
This is the bruteforce method 😄 but if we dont find a way we probably need to it this way.

I found out how to fetch static variables without us parsing the whole source code manually.
For more check this PR out: #20

I will therefore close this, thanks for your contribution regardless!
