Rem Send

A Remote Procedure Call framework for Godot C#.

Features

• Call RPCs with static typing.
• Return values from RPCs.
• Send variant-incompatible values (with MemoryPack).
• Extra access enum (peer -> authority).
• Created for use in a real MMORPG.

Dependencies

• MemoryPack

Examples

[Rem(RemAccess.Peer)]
public void SayWordsRem(List<string> Words) {
    foreach (string Word in Words) {
        GD.Print(Word);
    }
}

Rem(1, () => SayWordsRem(["cat", "dog"])); // The method name and arguments are extracted from the expression.

[Rem(RemAccess.Peer)]
public int GetNumberRem() {
    return 5;
}

int Number = await Rem(1, () => GetNumberRem());

Limitations

• Uses reflection (may be slow, incompatible with trimming, incompatible with GDScript)
• Optional parameters must be passed explicitly (due to a current limitation with Linq Expressions)
• Only supports 4 transfer channels (since they are implemented manually)

Setup

1. Install MemoryPack through NuGet or by editing your csproj file:

<ItemGroup>
  <PackageReference Include="MemoryPack" Version="1.21.3" />
</ItemGroup>

2. Add the Rem Send addon to your project and build the project.

3. Create a RemSend node (or create a node and attach the RemSend.cs script).
