Creating a coremod

[voidzm]

I'm trying to convert an extensive mod that I've been writing into a coremod (I need some ASM capabilities for some features). However, I can't really find much information on how that is supposed to work, or how a coremod is supposed to be structured internally. Do you still use the @Mod/@NetworkMod annotations, or does the mod's IFMLLoadingPlugin object function as the new "base" class of the mod? If so, how do you specify a PacketHandler and other information that usually gets inputted into those annotations?

 

Or do I have this all wrong, and a coremod is supposed to be a separate entity from the main body of the mod?

 

Any information would be helpful at this point.

Immibis microblocks (his mod packages also contain sources; see mods.immibis.microblocks.coremod package there, start from MicroblocksCoreMod class):
