Oceania

A procedurally generated 2D sandbox game set underwater. Written in Pygame. Created by Kai Kuehner, 2013-2018.

TODO

• Port to Monogame
  • just try rendering 2 layers of tiles
• Worldgen
  • Biomes
    • Choose biome based on chunk
      • Multiple 1d Perlin noise functions
        • Since using just 1 will cause biomes to always be sandwiched between same partners
        • Temperature, liveliness?
      • Each biome has temp, life in JSON
      • Generate Voronoi diagram from biome placements (render this for debug)
      • When generating world, get x and y into biome diagram from a pair of 1d Perlin noise functions on world x
      • Get nearest two biomes- if almost halfway between them, lerp between them to get mixed biome
    • prescriptive (base height on biome)
      • Terrain scale
      • Surface material cutoffs
      • Gradients (done)
    • Smooth transitions between biomes
      • vertically- heights
      • horizontally- mix blocks together?
      • transition minibiomes?
  • Decorations
    • seeded random(x) is within some range
    • Allow for multi-chunk structures
      • check if adjacent chunk would have a structure
  • Ores, etc.
    • 2d Perlin noise
  • What is at the center (bottom) of the world?
    • hot impassible water?
    • solid rock?
    • lava?
  • Vertical chunks
  • Multithreading
• All TODOs in code
• Structures can only be in one chunk (and overwrite each other all the time)
  • also messes up entity generation
  • structures across multiple chunks with perlin noise?
• Block breaking particles
• Block preview visualization is a bit off- probably due to use of outline
• Possibly render foreground water as semitransparent (so it goes over block breaking image)
• Make sharpened flint more effective on kelp
• Chests
  • remove * rendering (after entity generation is fixed)
• Inventory
  • Armor
• Texture improvements:
  • Font
  • Basalt
  • Game icon
    • also make this load during startup, not world creation
  • Block breaking animation
    • crop to CTM- pipes are really noticeable
  • Dark colored borders
• Favorite items so they don't get mass-transferred (or dropped?)
• Player:44 throws exception when collecting dropped itemstack? (dropping itemstack in wrong chunk?)
• Click outside of inventory or press R to drop item in world
• Sliding puzzle lock
  • 3x3 version
  • test solution checking
• Pipes
  • Transfer items- how?
  • CTM variations: solid, sametype
• Move basic item attributes (attack damage, break speed, harvest level) to JSON with defaults
• Move JSON parsing to separate module, it doesn't belong in World
• Structures with background- define characters to be pairs of foreground and background blocks
• Enemies drop healing hearts when killed
• When player is hurt, make the whole player image flash red
• Menus
  • Better text fields
    • show cursor
    • tab to go to next one
    • filter invalid keypresses (is this done already?)
    • arrow keys, shift, home/end, mouse click, etc. to change cursor
  • Scroll wheel scrolls world list
  • Validate name in world creation
  • More options
    • Key bindings
  • Delete world button (& confirm dialog)
• Player can spawn inside generated structure and get stuck
• CTM rendering is slow- figure out some solution for large contiguous masses
  • only update image when adjacent block changes?
• Keybinding (first in config, then in game menu)
  • Controller support
• DamageSourceStab and spear- hitbox around tip of spear
• Add reach attribute to items (just weapons)
• Render rotating attacks
  • arm- blit separate arm part onto item image? and don't render arm
  • Offset attack when swimming?
• Player jumps between swimming and stopped images while slowing down while hitting a block
• Scroll wheel click to pull out targeted block from inventory (or scroll to it if in hotbar)
• Bounding box issues
  • Just make player bounding box a constant small square in the middle
  • Moving right on the ground keeps standing anim
  • Player's head can clip into blocks on bottom or right corners
  • Keep swimming animation while key is held down (so player can slide into 1 block hole)?
  • Left and right animations for swimming up and down
• Press (or hold?) CTRL to switch to raycast-closest-hit mode (for mining a tunnel)
• Unpickling messes up inter-object references
  • DamageSourceSweep item and parent
• Clamp to grid issues
  • Player doesn't naturally align to grid against a horizontal block collision (can bump into block by holding down key)
  • Player can clip up/down into blocks
• Icon should load with main menu, not World
• Pixel scale
  • Add pixel scale to options menu
    • any problems when changing dynamically?
  • Make world load menu background work with any scale
  • Performance is awful with scale = 1
• CTM slowness
  • only change block image when updating adjacent in 8 sides?
  • also auto-generate CTM images from center, corners, edges, inside corners
• Cache large rendering chunks of world (whole vertical chunk?)
