We've seen that the Pi3D library can be used to create lots of interesting objects and environments. Using some of the more complex classes (or by constructing our own), whole custom spaces can be designed for the user to explore.
In the following example, we use a special module called Building, which has been designed to allow you to construct a building using a single image file to provide the layout.
Explore the maze and find the sphere that marks the exit
You will need to ensure that you have the following files in the pi3d/textures directory:
squareblocksred.pngfloor.pnginside_map0.png, inside_map1.png, inside_map2.png
These files are available as part of the book resources placed at Chapter05\resource\source_files\textures.
