The whole map in a few rows of braille: walls in one colour, marks — players, bases, goals — over them, each a dot or a two-by-two.

Cauldron2D.Minimap.rows(
  size: {width, height},
  solid?: &MyGame.wall?/1,
  cells: {30, 12},
  marks: [{me.pos, {255, 220, 0}, 2}, {enemy.pos, {255, 90, 90}, 2}],
  key: {:my_game, map_name}
)

Each row is a list of {text, colour} runs to lay side by side, in the shape a hud row takes. A braille cell holds two columns and four rows of the map scaled to fit. Where marks meet, the earlier in the list shows.

Options

• :size — {width, height} of the map in tiles. Required
• :solid? — a function from a tile to whether it is drawn as wall. Required
• :cells — {columns, rows} of the minimap. Required

• :marks — [{{x, y}, colour, 1 | 2}] in tiles. Default []

• :wall, :empty — the colours of walls and of cells with nothing. Defaults {70, 100, 230} and {40, 40, 60}
• :key — under which the scaled walls and the drawn cells are kept for later calls with the same cells and colours, in :persistent_term, so a call draws only the cells its marks touch. Default: none, drawn whole every call
