#mcdev #modding NeoForge contest is live and underway! Free to join and have fun!

Serverside Summer Minecraft modding contest being hosted by NeoForge! Check it out! #mcdev

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) #mcdev #modding

For #minecraft mods that have recipes that should only load when another mod is present, please use this condition in the recipe to prevent logspam: "neoforge:conditions": [ { "type": "neoforge:mod_loaded", "modid": "examplemod" } ] docs.neoforged.net/docs/resourc... #mcdev #modding

Just added a new optimization to my StructureLayoutOptimizer mod (1.16 to 1.21). For structures with many pieces that have many Jigsaw Blocks, this new code should reduce the layout generation time a ton legacy.curseforge.com/minecraft/mc... modrinth.com/mod/structur... #minecraft #modding #mcdev

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. #minecraft #modding #mcdev

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. #mcdev #modding

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. #mcdev #modding

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

If you need to check if a Minecraft mod is present in Neoforge before you run some code, do: if (ModList.get().isLoaded("modid")) { If you need to check if mod is on within a MixinPlugin, do this instead: if (LoadingModList.get().getMods().get("modid") != null) { #minecraft #modding #mcdev

We have held elections for the Steering Council (SC). Welcome new SC members @gigaherz.bsky.social, @marchermans.bsky.social and @telepathicgrunt.bsky.social! Read more at neoforged.net/news/sc-elec.... #mcdev #minecraftmodding #neoforge

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. #minecraft #modding #mcdev

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. (X in pic are skipped checks) #mcdev

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. #mcdev 1/2

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: github.com/TelepathicGr... #mcdev

#minecraft #modding tip: Cache the chunk when setting/checking large amount of positions for a speed boost. Example: ChunkAccess cc = level.getChunk(pos); ChunkSection's maybeHas method is super fast to check if a block is present in section. Note, use the level when setting BlockEntities. #mcdev

If you want to add a structure into your Minecraft mod, follow this tutorial’s readme and examples! You can do custom placement too if you wanted to spawn a structure at specific spots or more. Best part, users can config structures by datapack. github.com/TelepathicGr... #mcdev #modding #minecraft
