9. Game #8, Treasure Chest > Time for action — checking neighboring horizontal ...
We will create two methods for checking the neighboring tiles, as we need to do this for each axis (x and y), separately.
- Inside the
gameclass, add a new method calledCheckGemsX. As parameters, it will take the column and row, the gem type, and a mark flag.Method CheckGemsX:Int(column:Int, row:Int, gem:Int, mark:Bool = False)
- First, add a local
foundvariable of the type INT. It will be set once we find similar gems.Local found:Int = 0
- Initialize the slot.
tileMap[column-1][row-1] = -1
- Check if
columnis greater than1. It means there must be gems on the left.If column > 1 Then
- Start a FOR loop, stepping backwards from
column -1to the first gem on the left.For Local c:Int = (column-1) To 1 Step -1
