I was trying to update it to 26.1, which required a lot new tags and stuff. In the end it didnt end up working, but i kept the new tag stuff in there as it will be useful in the future.

Changelog

• revert to 1.21.11
• json updates
• add mandatory tags
• update files to 26.1
• update demo
• blep
• bro tf did i do here

Made it so you actually need the correct tool of the correct tier to break blocks, and made it so certain tools actually break blocks faster (client was stupid and didnt know this, so i have to tell it :c). But now its actualyl kinda playable? You can break trees and get wood, craft wooden tools then progress to stone. Though you cant go further than that cause we dont have furnaces so you cant get iron.

Changelog

• bro tf did i do here
• fix tags and stuff
• send item tags
• tool components
• fix block drops and ensure correct tools used (still gotta implement tools though)
• give player crafting table contents on close

Implemented managing the inventory in survival (cause its diffrent than creative), rn we completly trust the clients new slot suggestions, but that will change in the future. Also implemented crafting in the 2x2 grid in inventory and in crafting tables.

Changelog

• give player crafting table contents on close
• implement crafting table
• start of crafting with window stuff
• fix shaped matching
• crafting
• survival inventory managment
• swinging hand animation

Implemented major parts of player syncing and changed how entity syncing works:

• Player tick now manages spawning/despawning entities for player
• All players are added to the entities list
• Players manage their entity’s pos and rot
• Movement and rotation changes are sent to players in range, so players can see eachother now, but i still need to implement skins, along with implementing stuff like sneaking and hand animations

Changelog

• cargo fmt
• fix rotation
• rot
• player movement syncing
• blep
• finish block syncing
• block update syncing
• redo how entity spawning is handled
• fall damage bug fixes

Implemented health and damage. Currently only fall damage is implemented, and you can die and respawn. Currently you do not drop your inventory but ill fix that soon enough.

Changelog

• stupidly named packet
• make code more maintanable
• fall damage and respawning and dying
• add health and improve movement handling

Implemented dropping items and item stacks.
And implemented taking blocks and items from the creative inventory and moving things around in your inventory (only creative, as survival uses a diffrent packet)

Changelog

• item dropping
• creative inventory managment

Implemented a entity system with incrementing entity ids (player gets a entity id now, and its sent to the client in the login (play) packet). Also added item drops if you mine blocks in survival, and they simulate gravity and measure distance to player, and if player is close enough the player will pick up the item.

Changelog

• entity simulation
• entity picking up
• entity dropping
• start of entity system
• blocks get used
• gamemode switching
• gamemode start
• update progress

Added way better world generation! There are bigger diffrences in areas, so there can be both deep oceans and high mountains. Also added trees, grass and flowers. There are also caves and ores generating below ground, with deepslate below y=0. There is also a minor issue where worldgen is pretty slow but ill fix that in the future.

Changelog

• foliage
• optimize chunk sending to player
• better caves
• slight optimization
• make the world more minecraft-y
• deepslate
• optimize worldgen
• cave gen
• fastnoise was shit, switch to noise and make caves redstone blocks and remove stone to visualize caves
• caves and new noise thingy

Implemented a basic inventory and hotbar, and placing blocks will now use the block you currently have selected in your hotbar. Also added the /give ` command to give blocks or items.

Changelog

• /give cmd
• inventory saving
• hotbar syncing
• inventory
• improve player saving and add player loading

Added compression to packets, which made the world load legit 1000x faster, like it loads instantly instead of taking like a minute. Also added commands

Changelog

• change everything to use write_string
• add commands
• add compression
• bugfix
• fix stupid shit in my code
• fix write deadlocks
• bufixes

Implemented basic worldgen:

• Generates bedrock at y = -64
• Generates stone between y = -63 and up until 4 blocks under the surface
• Generates 4 dirt blocks then grass
• Generates water if surface under y = 62, and generates sand instead of grass
• Generates ores underground between -63 and 320
  In the image, ores above ground was due to testing, same with the chunks missmatching, i did that on purpose.

Changelog

• bufixes
• bugfix
• fix some stuff
• ore gen
• cargo mad
• make you spawn on surface first time
• optimize world gen
• superbasic generation
• make blocks be defined at buildtime instead of wasting resources on fetching from hashmap
• add noise stuff and bedrock placing
• restructure world module
• add a status section on homepage
• make all packet stuff take from a file that i can update instead of it being hardcoded
• use packets data from json, not implemented yet
• fix byte orders

Make the server actually work properly. Before i kept getting randomly kicked due to completly random errors while loading chunks. The issue was bytes kept getting out of order, and with the help of claude thats now fixed.

Changelog

• make all packet stuff take from a file that i can update instead of it being hardcoded
• use packets data from json, not implemented yet
• fix byte orders

I have been trying a lot to optimize the server and fix some critical bugs, but its just not working. I have improved some bad code but the server keeps crashing with random errors that dont make any sense. So its currently not working but ill try to downgrade to 1.21.10 or 1.21.9 and see if smth works

Changelog

• update stuff
• aaa
• aaaa
• bye bye demo
• aawerwaeG
• aejkhgiawegraw

Made an proper hompage, along with basic docs

Implemented:

• Sending chunk center and chunks to player as they move
• Improve concurrency by separating the tcp writer and reader
• Procedural generation of regions if get_region() cant find the region
• Save and unload all regions from memory if all players leave, as they arent needed (i will add unloading regions as players move later on)

And:

• Made further ram optimizations
• Made the code a bit cleaner

• Updated registries and packets to 1.21.11
• Implemented handling player movement and input (we have to calculate movement on server-side)
• Implemented player rotation
• Dont let players join if server is full
• Show actual player count when pinging server instead of placeholder saying 0

• Implemented sending player skins
• Implemented player remove packet
• Renamed the property player.name to player.username and all refrences

Make a lot of stuff sync to reduce async overhead, cause my code had a lot of stuff that didnt need to be async. Also fixed registry order as that was unpredictable ending in chat getting messed up. Screenshot shows an example of change in one packet. Also includes some work on trying to optimize the server.

Implemented chatting. It was a pain cause the docs are kinda lacking so i just had to try some random values for the chat type field until it worked loll.

Implemented the packet for sending player info updates, only implemented adding player, and making a player listed in the tablist. But easy to expand with just adding to the enum.

Made a log module that works as a drop-in replacement for all the old logging code, but also saves the logs to the logs/ folder. Also implemented breaking and placing blocks, but placing blocks is currently using stone as an placeholder. Breaking and placing blocks also modifies the chunks on the server and are saved, and will persist if you restart the server.

Create a simple site as the demo with a video and instructions on how to connect.
Site is on the “site” branch

For this devlog i did:

• Add view and simulation distance to config
• Generate more regions around 0,0, now making 4 regions
• Only send chunks that are within the distance client accepts (view distance * 2 + 7), so it needs to send from 4 different regions if you are on 0,0
• Load block data from an json file so i can access block ids with “BLOCKS.get(“minecraft:grass_block”).unwrap().default”
• Fix sending blocks

So this is sadly a huge devlog, but i spent so long debugging the data packets :(

This devlog adds the following

• Generating chunks, trying to match minecraft’s palette format (not very good at it but)
• Saving and loading chunks (with zlib compression, an 32x32 chunk region with only air is 2.8KiB)
• Sending chunk and light data to client (no light data for now, just sending zeroes)
  Making the chunk packets work was an absolute pain as the packet documentation is kinda lacking on that front, but i ended up figuring it out after a long time.

For the next devlog im going to make sending actual blocks and just not air, which shouldnt be too hard.

Added the initial setup for saving, along with implementing player saving
Also added some of the base for chunk/world stuff

Upgrade packets to protocol 773 (1.21.10), and temporarily remove packet 0x44 (player_info_update).
Added sending server type to client, as shown in top right.
Also implemented sending the game event indicating client should start waiting to get chunk data
