Crate dotzuki_engine 

dotzuki-engine

Core trait definitions for a JRPG engine framework.

This crate defines the foundational abstractions that any JRPG engine implementation must provide. It has zero dependency on specific game data — all types are generic associated types or marker traits that the implementing crate supplies.

Design Philosophy

The traits in this crate follow these principles:

• Generic over game data: No concrete game-specific, item, or move types. All identifiers are associated types bounded by Copy + Eq + Hash + Debug.
• Provider pattern: Data providers (tilesets, maps, palettes, tile metadata, render data) are obtained through a single GameData master trait, enabling dependency injection and testing.
• No I/O, no platform: This crate contains only trait definitions and simple data types. No file loading, no GPU code, no platform calls.

Modules

Module	Contents
tileset	TilesetTrait and TilesetProvider — tileset loading and querying
tile_meta	CollisionType, TileMetaTrait, TileMetadata — collision and terrain
tilemap	TilemapEntry, Tilemap — 16-bit tilemap with per-tile metadata
map	MapTrait, MapProvider, MapConnection — map data and connections
palette	PaletteTrait, PaletteProvider — colour palette lookups
render_data	RenderData — display-name and metadata lookups for moves, items, species
save	SaveData, SaveManager, SaveStorage, SaveError — save/load with CRC16
link	NetworkTransport<M>, TransportError, ChannelTransport<M>, LinkRole — game-agnostic link-play transport seam (zero-I/O)

Modules

battle

Battle system trait definitions for a JRPG engine framework.

camera

Camera system — viewport positioning with smooth follow, zoom, and boundary clamping.

items

Items module

link

Link-play transport seam — game-agnostic and zero-I/O.

map

menu

Menu system abstractions for JRPG engine.

metatile

metatile

overworld

Overworld systems, in two tiers — pick the one that matches the game:

palette

party

Generic, game-agnostic party / monster model (milestone P0a).

render

Map layer definitions, rendering state, colour types, geometry types, and the pixel framebuffer.

render_config

Render configuration for the engine.

render_data

save

Save system for JRPG engine.

text

text

tile_meta

tilemap

Game Boy Advance-style tilemap with 16-bit metadata per tile.

tileset

trigger_manager

trigger_manager

Macros

effect

Declarative effect builder (design §4.1). Expands to an Effect whose hooks is a &'static slice of EventHooks. Usable anywhere an Effect expression is expected (incl. the initializer of a const/static).

Traits

GameData

Master trait that provides access to all game data subsystems.
