A procedurally generated 2D sandbox game set underwater. Written in Pygame. Created by Kai Kuehner, 2013-2015.

• Button does not function correctly when run from Game.py
  • problem with global variables- make designated launcher class
• Structures can only be in one chunk (and overwrite each other all the time)
• Check for entity collisions in nearby chunks (all loaded?)
  • Pick up items across chunk border
• Pause game when opening GUIs
  • Pause game at all
• Figure out why spawn chunks don't save
• Block rendering
  • Redo according to Kenney's triangle system? or full CTM
  • Mask with solid magenta triangle(s), then set that as transparent
• Block ID crash
  • make solid true by default

• World generation
  • Caves
    • Lava tubes
    • Air pockets?
  • Hydrothermal vents
  • Spawn midpoint displacement
  • Biomes
    • Rock types
      • Basalt
      • Chalk (used for quicklime- limelight)
      • Gabbro
    • Ores - Manganese nodules- manganese (27-30%), iron (6%), nickel (1.4%), copper (1-1.3%), cobalt (0.25%)
      • Chromite (chromium- used for Vitallum, steel, tanned leather)
      • Cobalt (used for Vitallum, steel drill, )
        • Cobalt crusts- cobalt, manganese, iron layer on seamounts
    • More structures
      • Improve temple
      • Volcanic pipe- kimberlite, diamond
• GUI work
  • Inventory
• Entities
  • Enemies, friendlies
• Player
  • Animation
• Crafting
  • Larger crafting tables- 2x2 (from some item in world), 3x3, 4x4, 5x5, 9x9
  • Slot for crafting tool- hammer for metal work, etc.
• Ore processing

  • T1: Cold forging- shape metal into basic tools with a stone hammer (copper)
  • T2: Hot forging- up to 750°, melt metals in forge, basic alloys, cast into molds (tin, lead, zinc, brass, bronze)
    • Craft molds with sand + clay, imprint with some natural material for type (e.g. narwhal horn for sword blade)
    • Melt sand into glass, pour into empty mold
  • T3: Iron, steel, mangalloy
  • T4: advanced alloys
  • Place crucible over hydrothermal vent, place ore into crucible, inject into mold for whatever part (like sword blade)
• Menus
  • Get input from user to name world
  • Pause, save & quit, options
• Combat
• Sound
  • freesound.org
• Block placement & destruction
  • Make block breaking take time
  • Make target only show when pointing at block within range???
    • could remove target entirely, highlight selected block/space?
  • Multiblocks- have special multiblock interface that checks specific blocks
    • Hammer cycles through block variations
• Lighting
  • set brightness per tile? use circlecollector style gradient hacks?
• Background tiles
  • hold shift to interact with background
  • tiles are darkened and overlaid with water image
• Energy
