TODO

• Structure editor
  • Make saving/loading actually work, and test worldgen functionality
  • Background editing
    • scroll? or spacebar? to switch layer
    • in background layer only render background, in foreground render background darkened behind
    • auto-place background when editing foreground? toggle for this?
  • GUI stuff
    • Text fields
    • Checkbox
  • PlaceableObject? class for cursor contents: Block(string), Anchor, InPopup
  • Anchors palette
    • Scrollable block selection popup
  • Properties text fields
    • Number text box
    • mark unsaved change when edited
  • Water, Empty rendering
  • Make scroll amount matter in scrolling? (requires input changes)
• World generation
  • Island/surface biomes
    • Balance depth so that only island/surface is at y=0
  • Lerp biomes
  • Add another noise function worth of caves?
  • Ore- variable # of noise functions per ore type (cluster frequency)
  • Sky biome with clouds and floating islands
  • Structures
    • Puzzle, coral
    • Loot tables (once inventories & chests are done)
    • Random elements
      • Generate with SpawnedStructure
      • Kelp with random height and branches
      • Dungeons with random mazes
      • Rooms hook together like jigsaw pieces
• Input
  • cursor position- mouse or right joystick (for targeting, inventory)
    • should snap back when not held for targeting
  • button selection in menus- use mouse if moving, up/down/left/right on keyboard/gamepad if mouse not moved
  • make inventories work with gamepad
  • In-game rebinding menu
• Rendering
  • Ore rendering- keep track of base block, so that it doesn't have to check adjacent tiles (necessary for ore surrounded with other ore)
    • make ore an entity
  • Pipes/kelp render type- 4x4 spritesheet
  • Render block as item (scaled down by 50%, connected texture uses single block texture)
  • color tint or just outline for player target? lightening is hard especially above water
    • darker for background? or both?
  • Randomized textures render type (combine with CTM?)
  • Water- no texture, bigger scrolling background
  • Rework light overlay to be per-pixel instead of per-sprite (smooth lighting, halfway out of sea surface)
• Copy over everything from Python
  • Player
    • Fixed, square bounding box centered on image
    • Make hair (+ body/tail?) white and use Monogame color multiplication to allow any color
    • Boost control to dash in direction
  • Menus
    • Options- gameplay, block scale
  • Entities
  • Inventory
  • Sound
  • Tile puzzle
• Apply knockback to EntityLiving movement
• Biome lerping- backgrounds, music (music is 0 when mix is 0.5 or less, scales up to 1)
• Make viewport smoother for scale=2
• Save world state & chunks when closing world
• Make sure serialization works
  • references (including Player) across files
  • image reloading (combine with SetWorld)
  • Consistent block IDs in Resources
    • Serialize and load blockIDs in World?- only add new mapping if not already present (keeps IDs consistent with adding/removing blocks)
    • Save & serialize set of block ID mappings and compare it each time game is loaded?- for changed IDs, replace or remove (set to water/air)
• Set loaded chunk radius x&y based on screen size and scale
• Performance
  • Load chunks in background thread (await result, add to loaded chunks or generate when loading finishes)
  • Make generation smoother
• Remember full screen from last setting
• Everything from old README
• Use Monogame color tint to highlight targeted block (is it possible to lighten this way? seems to use multiply filter...)
• Nicer background without water texture (gray tint for background blocks, no overlay)
• Spawn rates based on liveliness
• Biomes
  • Surface
    • Island
    • Glacier
  • Shallow
    • Beach
    • Rocky shore
    • Neritic zone
    • Mangrove forest
    • Seagrass bed
    • Kelp forest
    • Choral reef
    • Ice edge
    • Seamounts- cobalt crusts
    • Trench? (hadal zone)
  • Cave
    • Lava tube
    • Basalt cave
    • more caves...
  • Abyss
    • Too dark to see without bringing a light source
  • Core
    • Too hot, damages you if you don't have heat protection
    • Need increasing levels of heat protection to go deeper
    • Put some endgame ores/structures here
• Fish breeding for automated resources?
• Phosphorus for heat generation?
• Mod support
  • Load blocks, biomes, entities, etc. from Mods folder
  • Vanilla overrides (priority? before/after dependencies? load order?)
  • content pipeline?
• Enemies
  • Surface
    • Birds (from Animals RPG Sprites)
    • Flying rays https://i.imgur.com/SyGVm1y.gif
  • Open waters
    • Guys that try to ram into you, you can deflect them back into other enemies/walls
  • Cave
    • Pulls back and springs towards you
    • Shoots grapple hook towards you and pulls along it
    • Stationary guys that shoot lasers spinning around

Progression:

1. Sea

• T0: Stone Age
  • Spawn in world
  • Pick up flint
  • Right click flint with it several times to make Sharpened Flint
  • Right click Sharpened Flint on bone (from killing something or skeleton in world) to make basic pick
• T1: Copper Age
  • Collect copper ore
  • Cold forging- heat? then hit with hammer? to make pick head or sword blade
  • Copper tools, armor
  • Shells, eggshells, coral -heat-> quicklime + sand -> limestone
• T2: Bronze Age
  • Collect tin, lead, zinc ore
  • Crucible - Place crucible over hydrothermal vent, place ore into crucible, inject into mold for whatever part (like sword blade) - Up to 800°, melt metals in forge, basic alloys, cast into molds
    • 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
  • Alloys- brass, bronze
  • Machines
  • Alchemy?
• T3: Iron Age
  • Collect iron ore
  • Bloomery?
  • Steel
  • Mangalloy
  • Alchemy?
• T4: Final Age
  • Collect cobalt, chromium from roof of abyss
  • Make vitallum
  • Make Reverse Atmospheric Diving Suit, climb ashore

2. Land/Abyss

• Walk on land- slow & clunky at first, short jumps
• Explore islands
• Trade with kobold lizard natives
• Explore sun temples
• Upgrade suit- faster, jump higher
• Fight sun cult to get light source
• Go down to abyss now that you can see there
• Get resources for flight from eldritch abyssal beasts

3. Sky/Core

• Flight (clunky jetpack at first, then better wings)
• Explore floating sky temples
• Get heat resistant jelly to explore core
• Core temples and ores
• Cosmic space stuff
