Status

craftd is on github. This is a developer preview for feedback. It doesn't currently implement much of the Minecraft protocol, but you can follow along and track progress. Check back later for release tarballs and eventually binaries.

Roadmap

0.3 - Future (May change)

GOAL: Stable core and operation with 100 player over 24 hours

• Complex world modifications
  • Implement simple World Block Actions
    • Grass Spread
    • Fire Spread
    • Water/Lava Spread
  • Fix Implementation of Time
  • Implement Lighting Engine
  • Implement Block Identifiers (Wood, Stone, etc)
• Basic Mobs
  • Implement Pigs
  • Implement Cows
  • Implement Sheep
  • Implement mutant duck/bird thing we call Chickens
• Correctly Implement Creative Mode

0.2 - In Progress

Experimental Branch can be found here

GOAL: Stable core and operation with 100 players over 30 minutes

• Simple world modifications (digging/placing blocks) (In Progress)
  • World saving (Currently in Memory)
    • Implemented Crimity's seemingly faster chunk hashing code (Experimental build in progress)
    • Basic digging (Experimental Build Done, needs overview)
      • Creative Mode (Done)
      • Survival Mode (Done)
    • Basic block placement (Experimental Build in progress)
      • Creative Mode (Buggy, but Working)
      • Survival Mode (Same as Above)
    • Chunk Saving/Loading
• Implement Protocol 17 (MC 1.8.1) Structs
  • Update survival plugin to 1.8 specs (currently is 1.4)
  • Packets (Almost Done, need packet 0x83)
    • Check packets against newest protocol for accuracy
  • Mobs
  • Per-World Dimension and Mode (Partially Complete)
• Improved Error handling
  • Catch socket errors

0.1a - Released

Experimental release exploring the Minecraft protocol and various libraries. Basic support for loading worlds and walking around.

Unplanned

These depend on developer interest and current needs.

• Proxy (dotblank?)- re-implement proxy support to front-end other servers for multi-world, protocol optimization, etc.
• InfiniCraft - if this isn't dead, implement it some time https://github.com/InfiniCraft/

Dev stuff

Things that have been hashed out:

• Autotools build system for cross-platform ease & possible distro inclusion
• libevent2 cross-platform event polling and network I/O
• Fast packet state machine and variable length packet decoder
• Pthreads worker pool
• libevent2 integrated httpd
• Daemon basics -- need conventional SIG handlers, SIGHUP, pid locks
• Choose a FOSS license -> Simplified BSD
• Logging. XSI/Single UNIX Specification syslog most likely. -> syslog with alternative stdout selector at runtime.
• Configuration files -> JSON formatted
• Chat, motd, string handling (bstring)
• Basic NBT read and write support
• Chunk sending
• Dynamically tunable worker pool

Future directions/TODO:

These are future research and development ideas in arbitrary order.

• World file format. custom w/import-export? BerkeleyDB?
• Sparse matrix for ^?
• Binaries for Linux, Win32(MinGW), FreeBSD
• Stress test w/large num users - Goal 100+ simultaneous
• Use more zero copy I/O
• JSON-REST admin/status API
• Security audit - perpetual
• Running from a chroot
• Native WIN32 threading with MinGW - needs a contributor/maintainer
• Protocol testing framework
• IPC to an IRC relay agent
• Alternative/improved protocol for NPCs, bots, scripting?
