This is the first of four commonly called events during mod initialization.
Called before
FMLClientSetupEvent or
FMLDedicatedServerSetupEvent during mod startup.
Called after
RegistryEvent.Register events have been fired.
Either register your listener using
AutomaticEventSubscriber and
SubscribeEvent or
IEventBus.addListener(Consumer) in your constructor.
Most non-specific mod setup will be performed here. Note that this is a parallel dispatched event - you cannot
interact with game state in this event.
