If your #minecraft mod need to check if a position is near your block (like during entity ticking), do not do a scan. Instead, register your block into the Point Of Interest system and use that to grab your nearby blocks much faster! Greatly reduces lag compared to blockpos scanning. #mcdev #modding

When creating a new entity in a #minecraft mod, always try to use the entity's own RandomSource in the entity's class. You have to use this random and not the incoming level's random or else your entity can crash the game when the entity spawns during worldgen (Very hard to diagnose)

Echoing my message on Discord to here, be sure you are not storing passwords, secrets, webhooks, etc in SERVER type configs on Forge/Neoforge. The config is synced to clients so try and use unsynced configs or roll out your own for private info you’re storing in your mods.

Working on trying to make my Bumblezone mod's worldgen a bit faster for 1.20.1 and 1.21.1 #minecraft. Feels quite a bit faster than unmodded overworld. The main two things taking up most of worldgen in my mod are Surface Rules and the caves using noise generators.

Ever since 1.20.5 #Minecraft, NBT on items have been replaced with DataComponents. As a mod dev, you should have dedicated fields for your data in these components.
The CUSTOM_DATA DataComponent holds legacy nbt and if you do use it, ALWAYS call copyTag() or else bugs will happen.

When spawning entities during worldgen, use `EntityType..create(` and then `worldGenRegion.addFreshEntityWithPassengers(`.
If you call `EntityType..spawn(`, you will deadlock/lock-up the game as that will call non-worldgen safe methods on the serverLevel.

When you define your getShape method in a custom block, please do not construct the VoxelShape directly in there. getShape is called excessively and VoxelShape creation is not cheap. Create the VoxelShape in a static field and call that pre-made VoxelShape in getShape.

When using a slow-moving noise generator to sample a huge number of positions during #minecraft #modding worldgen, you can skip over a few spot if the noise value is too far from your target threshold. Gives a significant speed boost when values are at extremes.

When making your own mob while #minecraft #modding, using EntityDataAccessor to have synced data is fine. But do not mixin add those to other people's/vanilla's mobs. They are order dependent so if the mixin applies in different order on client vs server, it'll cause disconnect people.

A change I would like to highlight from #Minecraft 1.21.4 is a bug-fix: MC-272062 - "Dimension padding doesn't affect the start piece." This fix makes it possible for data packs to add structures to the end without them ending up in in the void at y=0. #mcdev

To check if you are in bounds of a structure when #minecraft #modding. Use StructureManager from the ServerLevel like this:
StructureManager sm = serverLevel.structureManager();
However, it's not worldgen safe so copy and modify it to use a WorldGenRegion instead:

#minecraft #modding tip: Cache the chunk when setting/checking large amount of positions for a speed boost.
