Method Summary
Method Attributes | Method Name and Description |
---|---|
all()
Returns all objects in tile map
|
|
at(x, y)
Get objects in cell that exists at coordinates x / y
|
|
atRect(rect)
Returns occupants of all cells touched by 'rect'
|
|
cell(col, row)
Get objects in cell at col / row
|
|
clear()
Clear all cells in tile map
|
|
push(obj)
Push obj (or array of objs) into our cell-grid.
|
|
pushAsPoint(obj)
Push objects into tilemap.
|
|
pushAsRect(obj, rect)
push obj into cells touched by 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
|
|
sortCells(sortFunction)
Sort arrays in each cell in tile map according to sorter-function (see Array.sort)
|
|
toString()
Debugstring for TileMap()
|
