PacketGen

Source generator for the netcode packet scripts in https://github.com/CSharpGodotTools/Template

Input:

public partial class CPacketPlayerInfo : ClientPacket
{
    public string Username { get; set; }
    public Vector2 Position { get; set; }
}

Output:

public partial class CPacketPlayerInfo
{
    public override void Write(PacketWriter writer)
    {
        writer.Write(Username);
        writer.Write(Position);
    }

    public override void Read(PacketReader reader)
    {
        Username = reader.ReadString();
        Position = reader.ReadVector2();
    }
}

Input:

public class TestPacket : ClientPacket {}

[PacketRegistry(typeof(ushort))]
public partial class PacketRegistry

Installing as Local NuGet Package

Copy the .nupkg from bin\Debug to main project.

Add a file named NuGet.config to the main projects root folder with the following contents:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <packageSources>
    <add key="LocalNugets" value="Framework/Libraries" />
    <add key="nuget.org" value="https://api.nuget.org/v3/index.json" />
  </packageSources>
</configuration>

The name for the key LocalNugets can be changed to anything you'd like. Change the Framework/Libraries path to point to the .nupkg package file.

Add the following to the main projects .csproj file:

<PackageReference Include="PacketGen" Version="*" />

Replace * with the explicit latest version or keep it as is.
