Time for action – building walls

1. 1. Add the following to the declarations area of the Maze class:

   VertexBuffer wallBuffer;
   Vector3[] wallPoints = new Vector3[8];
   Color[] wallColors = new Color[4] { 
       Color.Red, Color.Orange, Color.Red, Color.Orange };

2. 2. Add the following code to the end of the constructor in the Maze class to initialize the w allPoints array and build the walls:

   wallPoints[0] = new Vector3(0, 1, 0);
   wallPoints[1] = new Vector3(0, 1, 1);
   wallPoints[2] = new Vector3(0, 0, 0);
   wallPoints[3] = new Vector3(0, 0, 1);
   wallPoints[4] = new Vector3(1, 1, 0);
   wallPoints[5] = new Vector3(1, 1, 1);
   wallPoints[6] = new Vector3(1, 0, 0);
   wallPoints[7] = new Vector3(1, 0, 1);
   
   BuildWallBuffer();

3. 3. Add the BuildWallBuffe r() method to the Maze class as follows:

   #region Walls
   private void BuildWallBuffer()
   {
       List<VertexPositionColor> wallVertexList = new List<VertexPositionColor>();
   
       for (int x = 0; x < mazeWidth; x++)
       {
           for (int z = 0; z < mazeHeight...
