How to communicate two different script verse files to each other.

I want to be able to call a function in a separate script or have a variable shared between two different scripts, but I cannot figure out how to get the two different scripts to be aware the other exists. Are there any examples of how to do this anywhere?

Hi @DolphimDom:

The team has got a bit of work to do on documenting how Verse scoping works, but to answer your question directly, if you had the following Verse scripts within your project:

In hello_world_device.verse:

Foo():void=
    return

And another function in hello_world_device2.verse:

Bar():void=
    Foo()

This should already be compilable. If you hover over the Foo symbol in VS Code, the LSP should also show you the full Verse path of that function symbol:

(/localhost/_MyProjectC:)Foo():void

Behind the scenes, the Foo and Bar symbols are defined under your project’s Verse path, which helps avoid namespace collisions. You can wrap these functions into modules/classes to help encapsulate them further:

my_module := module:
    Foo<public>():void=
        return

In your other script file, you’d then need to first import your new module:

using { my_module }

And then you can again use the function as-is in Bar:

Bar():void=
    Foo()

This isn’t the only way to do things in Verse and is far from the full set of rules surrounding scoping, but hopefully that gives you a clearer idea of where to start. Please feel free to provide feedback on the documentation located at: https://www.epicgames.com/fortnite/en-US/creative/docs/uefn/Verse/modules-and-paths-in-verse regarding this subject.

If I have 2 scripts but want to use := class(creative_device): is there a way to associate one with the other? My main desire is to use @editable in both which needs to be a class with a creative_device.

game_manager.verse

game_manager:= class(creative_device):

    OnBegin<override>()<suspends>:void=
       Foo()

hello_world_device.verse

hello_world_device := class(creative_device):
    Foo():void=
        Print("Hi")

Ended up figuring out from another forum post: How do I call a method on another verse device?

Basically for my example @editable then reference the other script, and then it can be called.

game_manager:= class(creative_device):
    @editable
    hello_world_device_ref: hello_world_device= hello_world_device{}
    

    OnBegin<override>()<suspends>:void=
       hello_world_device_ref.Foo()

Another solution to this problem would be using a global singleton reference to the device, I have an example of that here: I came up with a way to make singletons in Verse
