sdk.proto file for the offical Amazon GameLift Server SDK (C++, C#).
Before version 4.0.2 it was reversely created from the public available sources. Since 4.0.2 one person from AWS shared this file on the forum: AWS GameTech topic
Latest supported AWS GameLift Server SDK is 4.0.2. We will try to get regularly semi-official updates for the sdk.proto file from AWS GameLift team. But we will not be able to do so - we again can grab required information with reverse-enginnering.
AWS GameLift team promises that they later will publish Protobuf file officially as a part of the SDK. So hopefully someday this repository will be archived.
If you find any issues or just Protobuf file is outdated - feel free to create an issue or even create a pull-request! Any help is really appreciated!
