Managing the game field logic

Now we know how to store different shapes and render them. Let's implement some game logic to make these shapes interact with each other on a game field.

Getting ready

Refer to the Writing the match-3 game recipe to see how the game field is rendered.

How to do it…

1. The interface of clBricksField looks as follows:

   class clBricksField
   {
   public:

2. The size of our game field is 11×22:

     static const int FWidth = 11;
     static const int FHeight = 22;
   public:
     void clearField()

3. The methods to check if the figure fits freely into a position are as follows:

     bool figureFits( int x, int y, const clBricksShape& fig )
     bool figureWillHitNextTurn( int x, int y,
       const clBricksShape& fig )

4. This method stamps the shape into the specified position of the game field:

     void addFigure( int x, int y, const clBricksShape& fig )

5. The following code is the main game logic. Methods to calculate and delete same-colored cell regions:

     int deleteLines();
     int CalcNeighbours( int...
