XNA 4.0 Game Development by Example Beginner's Guide

Time for action – scores and scoring chains

1. Add a method to the Game1 class to calculate a score based on the number of pipes used:

   private int DetermineScore(int SquareCount)
   {
       return (int)((Math.Pow((SquareCount/5), 2) + SquareCount)*10);
   }

2. Add a method to evaluate a chain to determine if it scores and process it:

   private void CheckScoringChain(List<Vector2> WaterChain)
   {
   
       if (WaterChain.Count > 0)
       {
           Vector2 LastPipe = WaterChain[WaterChain.Count - 1];
   
   
    if (LastPipe.X == GameBoard.GameBoardWidth - 1) { if (gameBoard.HasConnector( (int)LastPipe.X, (int)LastPipe.Y, "Right")) { playerScore += DetermineScore(WaterChain.Count); foreach (Vector2 ScoringSquare in WaterChain) { gameBoard.SetSquare((int)ScoringSquare.X, (int)ScoringSquare.Y, "Empty"); } ...
