Configuration variables are variables defined on build configurations that Multiplay Hosting uses to generate a server.json file for each server. Each build configuration has a set of built-in variables, but you can create any number of custom configuration variables to track data that's important to your build. You might want to track a difficulty modifier, the game mode, or the game map.
