CS:GO User Messages
User Messages in Counter-Strike: Global Offensive
User messages in CS:GO use Google's Protocol Buffers (protobuf). Protobuf is a message/object serialization language that generates code to serialize the objects efficiently. For information about protobuf, see https://developers.google.com/protocol-buffers/docs/overview
On Windows, follow these steps to generate C++ classes from CS:GO .proto files.
- Download and extract csgo_usermessages.zip
- Download the protocol buffer compiler protoc-2.3.0 and extract it into the protoc-2.3.0-win32 folder that was created when you extracted csgo_usermessages.zip. The protocol buffer compiler is required to generate C++ classes from CS:GO .proto files.
- Download protobuf-2.3.0 and extract it into the same folder as csgo_usermessages.zip. This package contains files that are included by CS:GO .proto files
- Run make_cc_files.bat. The generated C++ files are created in subdirectory named generated_proto.
You can now use the generated classes in your C++ code to send user messages. Here is an example of how to send the HintText message
CSingleUserRecipientFilter filter( this );
msg.set_text( "ExampleHint" );
SendUserMessage( filter, CS_UM_HintText, msg );
