Utilities for working with Minecraft worlds asynchronously

Simple utility functions, can be used mainly for creating minigame worlds from an existing template world.

The class WorldUtils can be copied directly into your plugin.

Do the following in your onEnable():

WorldUtils.setPlugin(this);
WorldUtils.registerWorldInitListener();

This will register a listener that listens for WorldInitEvent, and disables keepSpawnInMemory to optimize loading times further (can be specified). Now, for copying a template world, it's just a matter of:

WorldUtils.copyAndLoadWorldAsync("template", "id1").thenAccept(success -> {
    // processing code
});
