RAIN's demo
The basic start of the demo will be similar to our others, a ground with several walls
around for our ships to travel. This is how the basic starting point of our demo should
look:

One of the first things we will need is the ability to query a random location in the
scene to spawn and find points to travel to. Create a class called
Ground
and add it
to the ground plane. This class will be used to provide higher-level information about
the level, the first of which is being able to find a random position in the level. Here is
the
Ground
class with the random position chooser method:
In the preceding code, we are able to ask for a random position at anytime from any-
where in the game. In the
Start
method for the
Ground
class, we store the
max
and
min
positions for it, and as we don't want positions on the very edge of the level, it is
scaled to 90 percent by multiplying by
0.9f
. The
min
and
max
positions are static,
so we can add a static method,
randomLevelPosition()
, that returns a random
