Overview

Package scripts holds the map generation for Caves: pure algorithms, no engine types. Generation is just Go code; the game turns the grid into tagged engine objects.

Functions

func FindOpen

func FindOpen(grid [][]bool) (int, int)

FindOpen returns an open cell as close to the map center as possible: the player's spawn point.

func Generate

func Generate() [][]bool

Generate returns a cave grid (true = wall) using the classic cellular automata method: random fill, then smoothing votes where crowded cells become wall and lonely walls erode away.

func Reachable

func Reachable(grid [][]bool, startX, startY int) [][2]int

Reachable returns every open cell reachable from a start cell (BFS flood fill). Placing gems only on reachable cells keeps every generated cave winnable.
