Project direction

  1. Same gameplay style as Everybody Edits
  2. Same block ID mapping. New blocks/packs must have a unique ID
  3. Guest "accounts" without chat or owned worlds
  4. Decentralised servers (community-hosted)

To-do:

  • Transaction IDs for packets
    • status_t Server::pkt_*(peer_t, Packet &pkt)
    • The return value is sent in an ACK-like packet when pkt[1] != 0
    • Useful for chat commands, bot programming and saner client communication
  • Private worlds
  • Achievements: death counter, timer (Lua side)
  • Login
    • Save server addresses, nickname and (optionally) password hash to database
  • Modding API (Lua)
    • Events with more than 1 payload
    • Per-player and per-world states (shared on join)
    • Ensure correct client-side prediction by sanity checks (physics dependent tile)
    • Movable objects, e.g. for mobs.
  • Moderator tools in the main menu
    • Event logger + "Inbox"
    • IP/user bans or mutes
  • Chat commands
    • /pm
    • /ignore (server-wide)
  • Audiovisuals
    • Animated coins (rotating mesh?)
    • More sounds: on collide, jump (also of other players)
  • Anti-Cheat
    • Opt-in by chat commands
    • Confirmation by server-side physics simulation
    • Abort simulation near modified blocks (tile number)

Maybe:

  • Group/crew system for easier per-world permission management

Code structure

  1. No dependencies from GUI to Client (use GameEvent)
  2. No dependencies between Client and Server

Server-only build:

  • Irrlicht dependency limited to headers only

Graphics

  1. >= 32x32 px textures
  2. Where it matters, use color-blind friendly colors

Helpful GIMP tools for texture creation:

  • Block borders:
    1. Select -> Shrink (1 px) : Adds a border
    2. Select -> Feather (5 px) : Smoother selection
    3. Select -> Invert : Actually selects the border
    4. Bucket Fill Tool with 100% threshold to fill the border (black?)
  • For rounded borders (e.g. candy pack)
    1. Select -> Rounded Rectangle (35%)
    2. Select -> Invert
    3. Delete (needs alpha channel)
  • Basic shading
    1. New layer, Mode "Multiply"
    2. Gradient Tool : White to grey gradient on new layer
