Start by setting up an empty project, the same way we did here.
Once the project is setup, open the
/src/rootGameObject.jsnobj. This will be our Level and in this part of the tutorial we will set it up for the game.
Create the boundary walls for the game.
Scale the ground
Copy the ground
Paste the ground 3 time so that there are 4 ground copies in total
Position the 4 copies such that they act as the walls
