Atlas map generator

Atlas is a 2d map generator with a unique twist.

Most tilemaps are 2d arrays, with tiles[y][x] being the tile at (x,y).

We instead use cells, each cell containing their respective tiles in Cell.Tiles.

Choosing the biome origin

Infect starts at a random cell using the world's seed. Use InfectFrom to start at the cell nearest a specific point, such as the center of an island:

world := atlas.NewWorld(256, 100, 11)
biomes := []atlas.Biome{
    atlas.NewBiome(atlas.NewFill(2)),
    atlas.NewBiome(atlas.NewFill(6)),
    atlas.NewBiome(atlas.NewFill(1)),
}
center := atlas.Point{X: float64(world.Size / 2), Y: float64(world.Size / 2)}
world.InfectFrom(biomes, 0.25, center)

InfectFrom uses the same spread and modifier rules as Infect, without advancing the world's random source. cell.GetBiome() returns the assigned biome index as int8; tile values also remain int8.

For custom map exports, use each cell's position in world.Cells as its ID and place its tiles at tile.X + tile.Y*world.Size in a flat array.
