Follow the examples to learn protobuf-Lua

Reference: cocos2dx uses Lua and protobuf

First, download the protobuf-gen-Lua plug-in. The plug-in git address is here.

After the download, go to the protoc-gen-Lua \ plugin directory and create a batch file:

@python E:\3rd\quick-x-protobuf\proto-gen-lua\protoc-gen-lua\plugin\protoc-gen-lua

 

Go to the addressbook. proto folder in the previous note and run the following command:

Protoc -- lua_out = generated Lua storage address -- plugin = protoc-gen-Lua = addressbook. proto

Press enter.

 

We will see an addressbook_pb.lua file under the target address. The content is as follows:

After the experiment is completed, I plan to integrate it into my mobile game demo. I will have the opportunity to read the protoc-gen-Lua code well. Now, the most important thing is to get off work.
