Sorcerous

Thanks for the reply, that all makes sense! I think that I understand your sentiment about 'premature optimization', although I'd argue that good coding practice hardly qualifies under optimization. I'm not trying to prioritize milking any last bits of performance in favor of creating features, I was just wondering if there's anything that I should look out for. It seems though, by what you're saying, that code simply working is paramount.

This is just a quick question for anybody out there who has a more intimate understanding of the event registration system and Forge as a whole. I'm creating what is planned to be a decently large mod, one that dabbles in the usual bits of world gen, tile entities that access/manipulate semi-large pools of data, potentially a few new biomes... etc. As a result of this, and knowing that such mods (if they're done well enough) will find their way into modpacks, I'm looking to fully optimize my mod performance-wise while I build it. So far, I've created some items, blocks and tile entities, and am looking in to registering event handlers. Reading the Docs, I've noticed that there are two methods with which events can be registered. One is through the use of Forge's main event bus, accessed through MinecraftForge.EVENT_BUS and the other is the 'mod event bus', accessed through FMLJavaModLoadingContext.get().getModEventBus(). The Doc mentions that the mod event bus should only be used 'in specific cases', but fails to mention why and what those cases actually are. Thus, my main question. Which should I prefer to use and for what, and why? Oh, and does it really matter? Will it affect loading time, in-game performance, or what? And assume that I am asking for a large-scale project, as I would guess that if one was registering a single listener and three blocks that it wouldn't really matter. Quick note: While I'm new to Forge modding, I'm experienced with Java runtime concepts as well as programming Minecraft in general (I've been writing Bukkit/Spigot Plugins for about 5 years, so I understand pretty much every basic and advanced technical concept in Minecraft). Knowing this, I'm hoping that anybody who chooses to answer will provide a more in-depth explanation of their answer, rather than 'X is more efficient than Y, trust me'. I'm always looking to gain a more in-depth understanding of Forge, especially considering that the official documentation on it is extremely rudimentary and light (as far as large APIs typically are concerned). Quick note 2: Any other advice for performance optimization is definitely welcome! Thanks in advance for any and all responses! Edit: I should mention that I'm writing for 1.15, with the intention of porting to 1.16 before release, as well as potentially back-porting as distantly as 1.12, depending on various factors.
