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

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.

Made some basic stuff work. Tho its still kinda broken cause the mc api keeps changing things up?? So it works on dev and not prod. But its not anything breaking, tho your ping might mess up packet order its fine just reconnect again

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.

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

it was a pain so it was mostly trial and error

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 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
