Minecraft Wii U Edition (Wii U) replacement server

Includes both the authentication and secure servers

Compiling

Setup

Install Go and git, then clone and enter the repository

$ git clone https://github.com/PretendoNetwork/minecraft-wiiu
$ cd minecraft

Compiling using go

To compile using Go, go get the required modules and then go build to your desired location. You may also want to tidy the go modules, though this is optional

$ go get -u
$ go mod tidy
$ go build -o build/minecraft

The server is now built to build/minecraft

When compiling with only Go, the authentication servers build string is not automatically set. This should not cause any issues with gameplay, but it means that the server build will not be visible in any packet dumps or logs a title may produce

To compile the servers with the authentication server build string, add -ldflags "-X 'main.serverBuildString=BUILD_STRING_HERE'" to the build command, or use make to compile the server

Compiling using make

Compiling using make will read the local .git directory to create a dynamic authentication server build string, based on your repositories remote origin and current commit. It will also use the current folders name as the executables name

Install make onto your system (this varies by OS), and run make while inside the repository

$ make

The server is now built to build/minecraft with the authentication server build string already set

Configuration

All configuration options are handled via environment variables

.env files are supported
