Functions

func NewLevel

func NewLevel(world w.World, width gc.Row, height gc.Col) resources.Level

新規に階層を生成する。 階層を初期化するので、具体的なコードであり、その分参照を多く含んでいる。循環参照を防ぐためにこの関数はLevel構造体とは同じpackageに属していない。

Types

type BuilderChain

type BuilderChain struct {
	Starter   *InitialMapBuilder
	Builders  []MetaMapBuilder
	BuildData BuilderMap
}

階層データBuilderMapに対して適用する生成ロジックを保持する構造体

func NewBuilderChain

func NewBuilderChain(width components.Row, height components.Col) *BuilderChain

func SimpleRoomBuilder

type BuilderMap

type BuilderMap struct {
	// 階層情報
	Level resources.Level
	// 階層を構成するタイル群。長さはステージの大きさで決まる
	Tiles []Tile
	// 部屋群。部屋は長方形の移動可能な空間のことをいう。
	// 部屋はタイルの集合体である
	Rooms []Rect
	// 廊下群。廊下は部屋と部屋をつなぐ移動可能な空間のことをいう。
	// 廊下はタイルの集合体である
	Corridors [][]resources.TileIdx
