This page will help you understand how to use Grpc for unity step by step and all the script in inside the HelloWorld demoscene.

But Before Start:

1. Define your .proto file. For example:

   syntax = "proto3";
   
   package helloworld;
   
   service Greeter{
    rpc SayHello(HelloRequest) returns (HelloReply){}
   }
   
   message HelloRequest{
    string name =1;
   }
   
   message HelloReply{
    string message=1;
   }
   

   For more information about protobuf, please check official website https://developers.google.com/protocol-buffers/docs/csharptutorial.

2. Place your .proto file inside Unity folder, and use our built-in tool to compile protobuf class. For more info about protobuf compilation tool, please check here.

   It should contains the .proto file, and 2 generated c# class. Note We already pre-compile the example helloworld.proto class for you.

   

Grpc Server Base:

1. Create a new c# class and inherient GrpcServerBase.

   

2. You need to bind the proto service with your custom class, for example:

   

Grpc Client Base:

1. Create a new c# class and inherient GrpcClientBase.

   

   SendGrpc() is the function that need to implement, which send the Rpc info to the server.

   SayHello() - The function name you define in .proto file.

   TRequest - The generic request you define in .protoc file which is the Hello Request.

You are now ready to GO:

1. Create a new c# monobehavior script and declare the grpc variable:
