Time for action — counting matching tiles


To count the matching tiles, follow the ensuing steps:

  1. 1. Add the method CountGems into the game class. The parameters are the first and second object.

    Method CountGems:Int(obj1:ftObject, obj2:ftObject)
    
  2. 2. Define four local INT variables that store the x and y positions of the objects.

    Local x1:Int
    Local y1:Int
    Local x2:Int
    Local y2:Int
    
  3. 3. Now define four INT variables that store the number of gems that were found.

    Local gemCountX1:Int
    Local gemCountY1:Int
    Local gemCountX2:Int
    Local gemCountY2:Int
    
  4. 4. Get the slot positions of both objects.

    x1 = GetSlotX(obj1)
    y1 = GetSlotX(obj1)
    x2 = GetSlotX(obj2)
    y2 = GetSlotY(obj2)
    
  5. 5. Retrieve the gem count of the first object. The position is the one of the second object, as that is where the first object is to be moved.

    gemCountX1 = CheckGemsX(x2, y2, obj1.GetTag())
    gemCountY1 = CheckGemsY(x2, y2, obj1.GetTag())
    
  6. 6. Do the opposite for the second object.

    gemCountX2 = CheckGemsX(x1, y1, obj2.GetTag())
    gemCountY2 = CheckGemsY...
