Public Class methods

deleteAllInstances()

Delete all tiles int the program. (Includes classes derived from tiles)

deleteById(id)

Deletes the tile with the given index

getAllInstances()

Returns an array of all tiles

getById(id)

Returns the tile with the given index

intersect?(tile1,tile2)

Find out if the given two tiles intersect.

new(x1=0,y1=0,x2=1,y2=1,inclusive=true,id=nil)

@inclusive decides whether or not tile edges are considered part of the tile

setAllInstances(ntiles)

Override the internal array of tiles with a new one
