MAKING FOUR

WALLS

We could just duplicate

this code four times

and do the appropriate

translating and rotating

for each one, but that

would leave us with a

lot of redundant code. It

would also mean that if

we want to make further

changes, like adding

windows, we would have

to be sure to add four

copies of that code, and keep them consistent with one another.

Instead, we will put the whole object inside yet another loop. To prepare our wall plus tower to rotate,

first we will translate this entire collective object (wall plus crenellations plus tower) away from the

center by wall/2 in the x and y directions. For x, we’ll need to move in the negati ...
