Changes

FIRST CHANGE

• LOGame >> initialize as in PharoByExample9

    | sampleCell width height n |
    super initialize.
    n := self cellsPerSide.
    sampleCell := LOCell new.
    width := sampleCell width.
    height := sampleCell height.
    self bounds:
    	(5 @ 5 extent: width * n @ (height * n) + (2 * self borderWidth)).
    cells := Array2D new: n 
                    tabulate: [ :i :j | self newCellAt: i at: j ]

• LOGame >> initialize as in Pharo 13

	| sampleCell width height n |
	super initialize.
	n := self cellsPerSide.
	sampleCell := LOCell new.
	width := sampleCell width.
	height := sampleCell height.
	self bounds:
		(5 @ 5 extent: width * n @ (height * n) + (2 * self borderWidth)).
	cells :=  CTNewArray2D width: n height: n 
		         tabulate: [ :i :j | self newCellAt: i at: j ]

Note: CTNewArray2D width: n height: n is what is changed, line 9

SECOND CHANGE

• LOGame >> toggleNeighboursOfCellAt: i at: j as in PharoByExample9

	i > 1 ifTrue: [ (cells at: i-1@j) toggleState ].
	i < self cellsPerSide ifTrue: [ (cells at: i+1@j) toggleState ].
	j > 1 ifTrue: [ (cells at: i@j-1) toggleState ].
	j < self cellsPerSide ifTrue: [ (cells at: i@j+1) toggleState ]

• LOGame >> toggleNeighboursOfCellAt: i at: j as in Pharo 13

    i > 1 ifTrue: [ (cells at: i - 1 at: j) toggleState ].
    i < self cellsPerSide ifTrue: [ (cells at: i + 1 at: j) toggleState ].
    j > 1 ifTrue: [ (cells at: i at: j - 1) toggleState ].
    j < self cellsPerSide ifTrue: [ (cells at: i at: j + 1) toggleState ]
