- title screen (continue/new/load/settings/help) and Esc pause menu - settings: language & sound, camera, graphics, game, rebindable keys; stored in localStorage and in every savegame (always applied on load) - savegames as JSON (.dcsave): download, load via file picker or drag & drop - autosave to localStorage every 2 minutes and when the tab is hidden/closed - configurable wall detail, light count, interface size, game speed, hints - audio behind a cargo feature so native tests run (cargo test --no-default-features) - savegame round-trip test Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

# DungeonCraft – Design Decisions
|
||
|
||
An original dungeon management game (genre: dungeon building & defence) that runs as WASM in the browser.
|
||
|
||
## Technology
|
||
- Rust + **macroquad** (WebGL), target `wasm32-unknown-unknown`
|
||
- User interface drawn entirely **in the canvas**
|
||
- Font: **DINOBYTE** bitmap font (CP437, 6×8 px, CC BY 4.0, see CREDITS.md) for all texts, integer scaled
|
||
- All UI windows use **CP437 frames** (single lines for panels, double lines for dialogs); bars (HP/mana/gate) are pixel bars
|
||
- Sound: event system + macroquad audio prepared (volume, mute key M); sounds will be generated later
|
||
- Languages: all in-game texts live in **language files** (`lang/*.lang`, key = text); English is the reference/fallback, German included, more can be added. The language is chosen on first start and stored in the browser.
|
||
- Repository language: **English** (code, comments, docs, commit messages)
|
||
|
||
## Graphics
|
||
- **3D**, **true isometric** (orthographic camera)
|
||
- Camera **freely rotatable 360° and tiltable**
|
||
- Walls with an **irregular surface** (noise displacement of the wall faces, seamless between neighbours)
|
||
- Textures: **procedural pixel art** (tile atlas)
|
||
- Units: **pixel sprites as billboards** (always facing the camera)
|
||
- Lighting: **dark + torches** – dark base level; claimed areas and light sources (torches, core, portal, gate) are bright, flickering light
|
||
- **Tile outlines**: subtle dark lines around every tile (floors, wall tops, vertical wall edges), following the irregular surface; toggle with G (later in the graphics settings)
|
||
- The UI is a 2D layer on top, including a minimap
|
||
|
||
## Controls
|
||
- Left click: use the active tool (drag a rectangle for digging/rooms)
|
||
- Right click: drop a unit from the hand
|
||
- Camera: WASD/arrow keys, right mouse drag, mouse wheel zoom, screen edge
|
||
- Rotate/tilt: middle mouse drag, Q/E rotate, R/F tilt
|
||
- Spells: 0 lightning, X heal, V summon imp
|
||
- Torches: placed automatically when ground is claimed; foreign areas are dimly visible
|
||
|
||
## Menus, savegames, settings
|
||
- **Title screen** (Continue, New Game, Load, Settings, Help) and **pause menu** on Esc (Resume, Save, Load, Settings, Help, Main Menu)
|
||
- Savegames as **JSON** (`*.dcsave`, format tag + version, ~300 KB): **save = download**, **load = file picker or drag & drop** onto the game window
|
||
- **Autosave** in the browser (localStorage) every 2 minutes and when the tab is hidden/closed; "Continue" on the title screen
|
||
- Settings: language + sound, camera (rotation/zoom speed, edge scrolling, invert mouse), graphics (tile outlines, wall detail, light sources, interface size), game (speed 1×/2×, hints), **key bindings** (conflicts swap keys; Esc and arrow keys are fixed)
|
||
- Settings are stored in the browser **and** in every savegame; loading a savegame **always applies** its settings
|
||
|
||
## Planned
|
||
- Music: own **XM/MOD replayer in Rust**, shared mixer for music + sound effects (streamed via a JS audio plugin, replaces macroquad audio)
|
||
- Soundtrack (composed as `.xm`, editable in MilkyTracker): title/menu, several calm build tracks, battle, victory/defeat jingles; **the title melody is a recognisable leitmotif in every piece**
|
||
|
||
## Game content
|
||
- **Digging**: mark earth/gold → Pit Imps dig, bring gold home and claim ground
|
||
- **Rooms**: treasury, lair, mushroom garden, training hall, library
|
||
- Claim the **portal** → creatures: kobold, cave spider, shadow mage, stone ogre (depending on rooms)
|
||
- **Needs**: sleep, food, wages (payday); unhappy creatures leave
|
||
- **Hand**: pick up / drop own units (max. 8)
|
||
- **Spells** (mana): lightning, heal, summon Pit Imp
|
||
- **Heroes**: knight, archer, priest, dwarf miner, paladin of light (they dig their way to the Soul Core)
|
||
|
||
## Goal
|
||
- **Victory**: destroy the Hero Gate
|
||
- **Defeat**: the Soul Core is destroyed
|
||
|
||
## Attacking the gate
|
||
- **Attack flag**: the player places a rally flag; free creatures march there and attack everything nearby (including the gate)
|
||
- **Gate**: about 3000 HP, regenerates slowly when not under attack
|
||
- **Defenders** appear at HP thresholds 75% / 50% / 25% (the last squad with a boss), challenging
|
||
|
||
## Hero waves
|
||
- **Endless** while the gate stands
|
||
- Strength follows the **army value** (sum of HP × damage of all creatures incl. levels)
|
||
- Wave strength **grows from 60% to 100%** of the army value, with some randomness
|
||
- **Grace period** of 5 minutes, then a **minimum wave** (e.g. 2 knights) even with a weak army
|
||
- Goal: always beatable, but challenging
|
||
|
||
## Operations / testing
|
||
- Build in Docker (multi-stage: Rust → nginx:alpine)
|
||
- Test build on port **18093**, later additionally a subdomain via Nginx Proxy Manager
