This code draws the grid of the tiles. It takes the width, height and tile size and creates a grid that matches.
|
|
Everytime it finishes a tile, it goes back the origin of the square to then continue to the next tile.
|
|
Once it finishes the row, it goes back to the origin of the first tile to then build up the next row.
|
|
At the end of drawing all the tiles, it moves the pen back to the origin.
