Field Detail

Method Detail

• all()
  Returns all objects in tile map
• at(x, y)
  Get objects in cell that exists at coordinates x / y

  Parameters:

  x

  y
• atRect(rect)
  Returns occupants of all cells touched by 'rect'

  Parameters:

  rect
• cell(col, row)
  Get objects in cell at col / row

  Parameters:

  col

  row
• clear()
  Clear all cells in tile map
• findPath(start_position, end_position, inverted)
  A-Star pathfinding Takes starting and ending x,y co-ordinates (from a mouse-click for example), which are then translated onto the TileMap grid. Does not allow for Diagonal movements Uses a very simple Heuristic [see crowFlies()] for calculating node scores. Very lightly optimised for speed over memory usage. Returns a list of [col, row] pairs that define a valid path. Due to the simple Heuristic the path is not guaranteed to be the best path.
  Defined in: tile_map_extra.js.

  Parameters:

  start_position

  end_position

  inverted
• push(obj)
  Push obj (or array of objs) into our cell-grid. Tries to read obj.x and obj.y to calculate what cell to occopy

  Parameters:

  obj
• pushAsPoint(obj)
  Push objects into tilemap. Disregard height and width and only use x/y when calculating cell-position

  Parameters:

  obj
• pushAsRect(obj, rect)
  push obj into cells touched by rect

  Parameters:

  obj

  rect
• pushToCell(col, row, obj)
  Push obj to a specific cell specified by col and row If cell is already occupied we create an array and push to that

  Parameters:

  col

  row

  obj
• sortCells(sortFunction)
  Sort arrays in each cell in tile map according to sorter-function (see Array.sort)

  Parameters:

  sortFunction
• toString()
  Debugstring for TileMap()
