Download premake 5 and copy the premake5 executable somewhere in your path. Please make sure you have at least premake5 alpha 14.
You need Visual Studio to build the source code. If you don't have Visual Studio 2017 you can download the community edition for free.
Once you have Visual Studio installed, go to the command line under the netcode.io.net/ directory and type:
premake5 solution
This creates netcode.sln and opens it in Visual Studio for you.
Now you can build the library and run individual test programs as you would for any other Visual Studio solution.
First, download and install premake 5 alpha 14 or greater.
Now go to the command line under the netcode.io.net directory and enter:
premake5 solution
This creates netcode.sln for you.
Alternatively, you can use the following shortcuts to build and run test programs directly:
premake5 test // build and run unit tests
premake5 server // build run a netcode.io server on localhost on UDP port 40000
premake5 client // build and run a netcode.io client that connects to the server running on localhost
premake5 stress // connect 256 netcode.io clients to a running server as a stress test
