                           RectMap

Known Subclasses:
  RectMapLayer

Rectangular map.

Cells are stored in column-major order with y increasing up, allowing [i][j] addressing:

    +---+---+---+
    | d | e | f |
    +---+---+---+
    | a | b | c |
    +---+---+---+

Thus cells = [['a', 'd'], ['b', 'e'], ['c', 'f']]

(and thus the cell at (0, 0) is 'a' and (0, 1) is 'd')

## Methods

| __init__(self, id, tw, th, cells, origin=None, properties=None)
| get_in_region(self, x1, y1, x2, y2) Return cells (in [column][row]) that are within the map-space pixel bounds specified by the bottom-left (x1, y1) and top-right (x2, y2) corners.
| get_at_pixel(self, x, y) Return Cell at pixel px=(x,y) on the map.
| get_neighbor(self, cell, direction) Get the neighbor Cell in the given direction (dx, dy) which is one of self.UP, self.DOWN, self.LEFT or self.RIGHT.
| get_neighbors(self, cell, diagonals=False) Get all cells touching the sides of the nominated cell.
| get_cell(self, i, j) Return Cell at cell pos=(i, j). (Inherited from cocos.tiles.RegularTesselationMap)

## Constants

| UP = ``(`0`,` 1`)``
| DOWN = ``(`0`,` -1`)``
| LEFT = ``(`-1`,` 0`)``
| RIGHT = ``(`1`,` 0`)``

## Method Details

### __init__

(Constructor) __init__(self, id, tw, th, cells, origin=None, properties=None)

Parameters:
  id : xml id
    node id
  tw : int
    number of colums in cells
  th : int
    number of rows in cells
  cells : container that supports cells[i][j]
    elements are stored in column-major order with y increasing up
  origin : (int, int, int)
    cell block offset x,y,z ; default is (0,0,0)
  properties : dict
    arbitrary properties if saving to XML, keys must be unicode or 8-bit ASCII strings

### get_in_region

get_in_region(self, x1, y1, x2, y2)

Return cells (in [column][row]) that are within the map-space pixel bounds specified by the bottom-left (x1, y1) and top-right (x2, y2) corners.

Return a list of Cell instances.

### get_at_pixel

get_at_pixel(self, x, y)

Return Cell at pixel px=(x,y) on the map.

The pixel coordinate passed in is in the map's coordinate space, unmodified by screen, layer or view transformations.

Return None if out of bounds.

### get_neighbor

get_neighbor(self, cell, direction)

Get the neighbor Cell in the given direction (dx, dy) which is one of self.UP, self.DOWN, self.LEFT or self.RIGHT.

Returns None if out of bounds.

### get_neighbors

get_neighbors(self, cell, diagonals=False)

Get all cells touching the sides of the nominated cell.

If "diagonals" is True then return the cells touching the corners of this cell too.

Return a dict with the directions (self.UP, self.DOWN, etc) as keys and neighbor cells as values.
