  Gets a tile by its grid index.

  Parameters

  • i: number

    X index.

  • j: number

    Y index.

  Returns Tile | null

  The tile or null if out of bounds.

getTileByPos

• getTileByPos(x: number, y: number): Tile | null

  Gets a tile by its world position.

  Parameters

  • x: number

    X coordinate.

  • y: number

    Y coordinate.

  Returns Tile | null

  The tile or null.

resize

• resize(): void

  Update sizes of map and tiles, for window.onresize.

  Returns void

spawnPoint

• spawnPoint(tries?: number): Coord

  Returns a random free spawn point.

  Parameters

  • tries: number = 0

    Recursion counter.

  Returns Coord

  coordinates.
