Drawing the buildings

To be honest, there is not much new you’ll learn in this chapter: the code of last chapter will be expanded, so you’ll also draw buildings on your floorplan, and then again roofs on your buildings. For this reason, I’ll summarize the adjustments and additions.

Because our program will support multiple buildings (5 in our case), we’ll need an array that contains the heights of these different buildings. So define this array at the top of your code:

 private int[] buildingheights = new int[] {0,10,1,3,2,5};

Next, we’ll process our int_Floorplan array, so the numbers in it reflect the building type. A 0 will remain a 0, but a 1 will be replaced by a random number between 1 and 5, the number of different buildings. To do this, add this code to the bottom of you LoadFloorPlan method:

 Random random = new Random();

for (int x=0; x< WIDTH; x++){

    for (int y=0; y< HEIGHT; y++)    {
        if (int_Floorplan[x,y] == 1)
        {
            int_Floorplan[x, y] = random.Next(differentbuildings) + 1;
        }
    }
}

We first initialize a random number generator, from which we draw random numbers by calling the Next method from it. This Next method will return a random positive number, lower than the argument passed. So every time a 1 is found in the array, it is replaced by a positive integer between 1 and 5.

Now we’ll start expanding the VertexDeclaration method. We start by letting the code we have also draw the roofings:

 for (int x = 0; x < WIDTH; x++)
 {
     for (int y = 0; y < HEIGHT; y++)
     {
         int currentbuilding = int_Floorplan[x, y];
         verticeslist.Add(new CustomVertex.PositionNormalTextured(new Vector3(x, y, buildingheights[currentbuilding]), new Vector3(0, 0, 1), (currentbuilding*2+1)/imagesintexture, 1));
         verticeslist.Add(new CustomVertex.PositionNormalTextured(new Vector3(x + 1, y, buildingheights[currentbuilding]), new Vector3(0, 0, 1), currentbuilding * 2 / imagesintexture, 1));
         verticeslist.Add(new CustomVertex.PositionNormalTextured(new Vector3(x + 1, y + 1, buildingheights[currentbuilding]), new Vector3(0, 0, 1), currentbuilding * 2 / imagesintexture, 0));
 
  verticeslist.Add(new CustomVertex.PositionNormalTextured(new Vector3(x + 1, y + 1, buildingheights[currentbuilding]), new Vector3(0, 0, 1), currentbuilding * 2 / imagesintexture, 0));
         verticeslist.Add(new CustomVertex.PositionNormalTextured(new Vector3(x, y + 1, buildingheights[currentbuilding]), new Vector3(0, 0, 1), (currentbuilding * 2 + 1) / imagesintexture, 0));
         verticeslist.Add(new CustomVertex.PositionNormalTextured(new Vector3(x, y, buildingheights[currentbuilding]), new Vector3(0, 0, 1), (currentbuilding * 2 + 1) / imagesintexture, 1));
     }
 }

Some interesting changes: first, the Z-coordinate is taken from the buildingheights array we initialized at the beginning of this chapter. Then you see that the X-coordinate from the texture (in fact, the U-coordinate, since we’re talking about the image space here) is dynamically calculated. Since we have 5 different buildings, the U-coord of the left side of the floor tile is 0, of the left side of the first roof is 2/11, of the second roof 4/11, .., of the last roof 10/11. In a formula: currentbuilding * 2 / imagesintexture. The U-coord of the right side of the floor is 1/11, of the first roof 3/11, …, of the last roof 11/11. In a formula: (currentbuilding * 2 + 1) / imagesintexture .

In a nutshell: if a 0 is encountered, the floor image is drawn, if a building number is encounters, the corresponding roofing image is drawn at the corresponding height, found in the buildingheights array. You can try running this code, and each time you run the program you’ll see another image roof at a different height.

The good news: we’ve already covered all the new stuff of this chapter. The bad news: drawing the walls of the buildings implies copying most of this code, only with different coordinates, normals and texture coordinates. To be complete, I’ll list the whole method here and quickly discuss it:

 private void VertexDeclaration()
 {
     float imagesintexture = 1 + differentbuildings * 2;
 
     for (int x = 0; x < WIDTH; x++)
     {
         for (int y = 0; y < HEIGHT; y++)
         {
             int currentbuilding = int_Floorplan[x, y];
             verticeslist.Add(new CustomVertex.PositionNormalTextured(new Vector3(x, y, buildingheights[currentbuilding]), new Vector3(0, 0, 1), (currentbuilding*2+1)/imagesintexture, 1));
             verticeslist.Add(new CustomVertex.PositionNormalTextured(new Vector3(x + 1, y, buildingheights[currentbuilding]), new Vector3(0, 0, 1), currentbuilding * 2 / imagesintexture, 1));
             verticeslist.Add(new CustomVertex.PositionNormalTextured(new Vector3(x + 1, y + 1, buildingheights[currentbuilding]), new Vector3(0, 0, 1), currentbuilding * 2 / imagesintexture, 0));

Whow THAT’s what I call a method! Quite impressive, but it contains nothing new to you. First the floors or roofs are drawn. Then we identify the places where 2 buildings of a diffent kind are sharing a wall. If this is the case, these walls are drawn. That’s about all this method does, but I don’t think there’s a more compact way to code … If you don’t agree, feel free to mail me your solution ;) You can also notice the arraylists Add method comes in very handy, as there’s no easy compact way to find out exactly how many walls will have to be drawn, a number we would otherwise need when initializing a usual array.

To make this a bit more impressive, let’s change the dimensions and contents of our int_Floorplan array:

 WIDTH = 20;
 HEIGHT = 15;
 
 int_Floorplan = new int[,]
 {
     {1,1,1,1,1,1,1,1,1,1,1,1,1,1,1},
     {1,0,0,0,0,0,0,0,0,0,0,0,0,0,1},
     {1,0,0,1,1,0,0,0,1,1,0,0,1,0,1},
     {1,0,0,1,1,0,0,0,1,0,0,0,1,0,1},
     {1,0,0,0,1,1,0,1,1,0,0,0,0,0,1},
     {1,0,0,0,0,0,0,0,0,0,0,1,0,0,1},
     {1,0,0,0,0,0,0,0,0,0,0,0,0,0,1},
     {1,0,0,0,0,0,0,0,0,0,0,0,0,0,1},
     {1,0,0,0,0,0,0,0,0,0,0,0,0,0,1},
     {1,0,0,0,0,0,0,0,0,0,0,0,0,0,1},
     {1,0,1,1,0,0,0,1,0,0,0,0,0,0,1},
     {1,0,1,0,0,0,0,0,0,0,0,0,0,0,1},
     {1,0,0,0,0,0,0,0,0,0,0,0,0,0,1},
     {1,0,0,0,0,0,0,0,0,0,0,0,0,0,1},
     {1,0,0,0,0,1,0,0,0,0,0,0,0,0,1},
     {1,0,0,0,0,1,0,0,0,1,0,0,0,0,1},
     {1,0,1,0,0,0,0,0,0,1,0,0,0,0,1},
     {1,0,1,1,0,0,0,0,1,1,0,0,0,1,1},
     {1,0,0,0,0,0,0,0,1,1,0,0,0,1,1},
     {1,1,1,1,1,1,1,1,1,1,1,1,1,1,1},
 };

This should already be runnable, but let’s first reposition our camera:

 device.Transform.View = Matrix.LookAtLH(new Vector3(20, 5, 13), new Vector3(8, 7, 0), new Vector3(0, 0, 1));

Now run this code! This is what you should see:
