How does RPCs work on Swift?

[paulovbettio]

In Godot's High-Level Multiplayer API, functions must be declared with the [Rpc] attribute in C# to make them callable by peers. Additionally, attributes like TransferMode can be set for specific RPC configurations. Here's an example in C#:

[Rpc]
public void Foo() 
{
    // Function logic here
}

[Rpc(TransferMode = MultiplayerPeer.TransferModeEnum.Reliable)]
public void Bar() 
{
    // Function logic here
}

How do I declare a function as an RPC in Swift to make it callable by peers? If there are any examples or references for implementing high-level multiplayer features in Swift, that would be greatly appreciated.

The [Rpc] attribute is a cute shortcut for calling Node.rpcConfig

So you would need to call that method with the parameters you desire once your Node is created.

We do lack examples or a tutorial for this.

As an aside, it might be nice to add an @Rpc macro that has a syntax similar to GDScript/C#, so users can put that decorator in a function and have the registration be done for them.
