I have a file structure like this

```julia
code - Folder
-- GameObjects.jl
-- Characters.jl

```

I want to use `GameObjects` inside `Characters.jl` but I get `GameObjects` not defined when I do:

```julia
# Characters.jl
module Characters
using .GameObjects
# Export statments
# structs and functions
end

```

I’m assuming that `.GameObjects` would behave like a sub module as specified in the [documentation](https://docs.julialang.org/en/v1/manual/modules/#Submodules-and-relative-paths)?

You are just missing an `include`:

```julia
# Characters.jl
module Characters
include("GameObjects.jl") # <-- !!
using .GameObjects
# Export statments
# structs and functions
end

```

To expand on this, unlike in Python, file/directory names/structure does not create modules/namespaces implicitly. You have to explicitly link them with `include` and `using`.
