1. Skydiving Guidance System
Alice Liddell (People) has taken up a new hobby: skydiving. She is on a helicopter
(Vehicle), wearing a parachute (Objects). She is to jump to the carrier (Vehicle), which
is a little way in front of her. In the world shown below, we added a half cylinder
(Shapes) inverted and connected to the helicopter to be used as a jump platform. A torus
(Shapes) was used to create a harness for Alice Liddell. (Although this isn’t absolutely
necessary, it is helpful due to Alice Liddell’s small waist compared to the parachute’s
The idea of this animation is to provide a skydiving guidance system to allow the user
to guide the movement of Alice Liddell as she jumps from the platform of the helicopter
and glides down to the carrier. When the user thinks Alice Liddell has hit the top of
the carrier, the user can press the Enter key to have Alice Liddell drop her chute.
Guidance system methods (as smooth and lifelike as possible):
jump: jump from the helicopter’s platform
glideForward, glideBack, glideRight, glideLeft: glide in the appropriate
swingLegs: legs swing a bit when gliding or jumping
dropChute: get rid of parachute (to simplify things, just have the chute rotate
as if it were falling and make it disappear)
Space bar—jump off the platform
Up/Down/right/left arrow—glide forward/back/right/left
Enter key—parachute drops
Remember that Alice Liddell should first jump off the platform prior to gliding and
should not drop her chute until she hits the carrier.
2. Why Did the Chicken Cross the Road?
A popular child’s riddle is, “Why did the chicken cross the road?” Of course, there are
many answers. In this project, the chicken (Animals) has a real sweet-tooth and crosses
the road to eat the gumdrops (Kitchen/Food) along the way.
6 - fromcone - tocone.
Write a game animation where the player guides the chicken across the road to get to
the gumdrops. Cars and other vehicles should move in both directions as the chicken tries
to cross to where the gumdrops are located. Use arrow keys to make the chicken jump left,
right, forward, and back. Use the space bar to have the chicken peck at the gumdrop. When
the chicken is close enough to the gumdrop and pecks, the gumdrop should disappear.
A recursive method is used to control the play of the game. If the chicken gets hit
by a vehicle, the game is over (squish!). The game continues as long as the chicken has
not managed to peck all the gumdrops and has not yet been squished by a vehicle. If the
chicken manages to cross the road and peck at all the gumdrops along the way, the
player wins the game. Signal the player’s success by making 3D text “You Win” appear
or by playing some triumphant sound.
3. Ice Danger
For this exercise, you can begin with a world completed in either Exercise 7 or 8—or
create a new skater world from scratch. Add a hole in the ice (a blue circle).
Make the world interactive to allow the user to use the mouse to move the hole
around on the icy surface. Now, as the skater is moving across the surface of the ice, the
user can move the hole into the skater’s path. Modify your method that skates the skater
forward to use an If statement that checks whether the skater is skating over the hole. If
she is on top of the hole, she will drop through it. If you have sound on your computer,
you may want to add a splash sound.Attachments
