20151102-20151108: Rotation
This week I started to think about how to display buildings with height in the 2D-view. When the x-axis was horizontal and z-axis vertical on the screen, I didn´t want to have the y-axis vertical or combined. So I decided to rotate x and z 45 degrees and then have only the y-axis vertical (as in games like StarCraft, SimCity etc.).
First I did some tests at the place in my code where coordinates are converted to canvas dimensions to get a working rotation. I also tried to rotate the drawing object (ctx context) prior to drawing, but this made things more complicated later in code so I kept working with conversion of coordinates.
Then I added drawing of walls for buildings, vertical offset when Y is higher than ground and some tests with drawing of cells in general.
