[1.10.2] When to register custom EventHandler?

[yooksi]

I've seen people register them in all three initialization phases, but which way is the correct one? I myself register it in the pos-Init phase and I've never had a problem with it. That raises the second question: is it really important when we do it?

As long as you register the event handler before the event is fired, it doesn't really matter when you do it.

 

You can annotate a class containing static

@SubscribeEvent

methods with

@Mod.EventBusSubscriber

to have it automatically subscribed to the Forge event bus at mod construction time (i.e. before preInit and before the registry events are fired). On the rare occasion that you need non-static event handler methods or a different event bus, you can still manually register your event handler.

Thank you, I definitely didn't know that we can register our event handler classes with a simple annotation. Basically I should use

@Mod.EventBusSubscriber

for all my event handlers, as they all contain only static methods and fields.

Oooh, that's handy.

I probably won't ever do it that way, but so slick, so clean.

 

The only event I'm are of that could get fired before your own mod's preInit that you might want to know about would be the OreDict registration event (as a mod loading before yours could register an ore during preInit).

I put mine in init()

 

Why? Because in preInit() is where I register and declare my items and blocks.  It kinda helps my brain figure this out.

 

If you're looking for say certain item or block in an event handler and is not registered or defined yet then you get a crash null pointer because items or blocks you were looking for don't exist yet.

 

But I guess you can put it at the end of  preInit() ?
