THIS IS VERY INCOMPLETE!

What is this?

This program is supposed to let a unmodified Minetest client connect to
another (mostly) unmodified Minecraft (Java Edition) server.
The Java Server version needed is 1.21.1, use ViaProxy if you need another version.
It compiles to a standalone executable, which will listen on 127.0.0.1:30000
for minetest and then proxy to a minecraft server specified in CONF_DIR/config.txt

You need nightly rust to build some dependencies (rustup default nightly).

Things that are still missing from a usable version:

• Crafting (Containers work (mostly, the UI is broken))
• Attacking/usable combat in general

Other, smaller, broken things:

• Rotated Blocks (ex. ladders that have a "side")
• Climbable Blocks (ladders/vines)
• Sneaking (waiting on upstream)
• Swimming
• Various block interactions like opening doors, using levers etc.
• Particles (will suck to implement, delayed until i cant do other stuff instead)
• Imprecisions in the movement (the client speed/gravity etc is not exact, so
  server/client will drift out of sync for up to half a block, at which point the
  proxy re-positions the client)

Even more limitations (ones that don't affect gameplay):

• The Minecraft server needs to be in offline-mode. I could fix that
  with azalea-auth but most people who might use this probably do not
  have a minecraft account. TODO later

• ArcticData only supports 1.20.4, but there isn't enough
  difference between 1.21.1 and 1.20.4 to make this a big problem IMO.

• Any Anticheats are likely near-certain to ban you.
  (if they don't, you probably found a bug in the anticheat? the traffic sent
  by this proxy is looking basically the same as that from any bot.)
  That is a slight danger even with GeyserMC in proxy mode, a similar
  (but mature) program basically doing the same thing for Bedrock.

• The program might work on Windows, but I am not testing this.
  If you find a windows bug, feel free to open a issue, but I will only work
  on that if it won't take too long. PRs fixing windows will be accepted.
  for now, i'd prefer getting this mess to work at all :3

• The upstream library for the minecraft protocol
  needs to be the bleeding-edge git version, but you can simply ignore
  this warning here if you only want to use this program.

• The proxy can only handle one client at a time, but could probably be
  rewritten to handle more clients without changing that much.

Isn't this violating Microsofts Intellectual Property?

The minecraft protocol is implemented by another library, not by me.

The textures this server is sending are NOT the official minecraft resources.
This repository contains NO textures, but the program will offer to download
the Faithful x32 texture pack (license) if no pack is found.
You can change what pack is used by changing the URL the config file
(at ~/.config/bridgetest.toml) points to or by changing the texture pack
itself, at ~/.local/share/bridgetest/textures).
(these paths are dirs::local_data_dir and dirs::config_dir, not hardcoded)
The 3D-models are also not provided by this program.
