Ultimate Super Cars: MV
Presented by:

Game in nutshell
Two players will play in a fierce competition to reach the
finish line first in their Ultimate Super Car.
Winning will not be easy, as the race track contains
challenging turns and obstacles. Each car has oil slicks
and turbo boosts which players can use to gain the upper
hand in a race.
Each Ultimate Super Car is customizable; from the way it
runs and handles, to the way it looks.
Players can view their win/loss records and see how they
compare to other racers.
Notes & Limitations
No more than two racers.
No single player mode.
No off road driving.
A racer can be so far ahead that the
other racer is no longer in view.
Start Screen
Racers will start on
opposite sides of the
track.
There will be a
countdown to a
green light, then the
racers can start to
accelerate.
Obstacle
This is a sample
obstacle on the
track that racers
must avoid.
If they collide with
an obstacle, they
will reset away from
the obstacle.
Turning
This is what a “turn”
on the track will look
like.
Crashing
This is what a crash
with another player
looks like.
Both racers will
reset on opposite
sides of the track.
Oil Spill
When a racer hits an
oil spill, they will
lose control of their
car temporarily.
Turbo Boosts
Turbo boosts will
increase the speed
of a player
temporarily.
Help Screen
A cell phone button
is assigned to
display the help
screen.
When it is pressed,
the screen shows
the help screen and
nothing else until
the button is
pressed again.
Model
Tidbits
Clients get the roadmap at
startup

Including the roadblocks
Server receives signals
from the clients every 100
ms
Server sends update info to
both clients every 160 ms
Bottomline: Server stores
state and takes care of all
the computations; clients
control the car speed,
steer, and oil leaks

Implementation using Servlets
and Midlets
Server incorporated into the
servlet
Midlets call the server on a
well known port
Midlets gets assigned a port
by the server
Support Analysis
Large LCD Screen


84 x 48 pixels
But, bigger the better!
Fast connection

About 500 bytes may need to be transferred every
10th of a second
Need moderate to large memory

Store the road map, which will become difficult with
more obstacles
A protocol to have 2-way communication
between servlet and midlets
Feasibility-1
Screen Size:

New cellphones have large screens
Fast connection:


current data transfer rates of 9.6 kbps to 14.4 kbps are
inadequate
2.5G technology with support for 56kbps to 144 kbps
would be sufficient.
Memory:

32KB should be enough
Protocol:


Allow servlet to send update info to midlets every 160
ms (when the timer fires on servlet side)
Allow midlets to send signals to servlet every 100ms
(when the timer fires on midlet side)
Feasibility-2
Poor Reception will remain a big problem


If poor reception for less than 2 seconds, then
retrieve state from the server
The game (including the setup) must start over if
no reception for over 2 seconds
Security


Tapping is easy
But MIDP 2.0 has some security features available
Tomcat breaks down

The entire game must start over
Anticipated users
Ultimate Super Cars: MV is accessible to people of all
ages.
People who take mass transit can pass the time by
playing this game.
The competitive nature of our game will keep
aspiring Ultimate Super Car racers coming back for
more.
The customizability of the cars keeps the game fresh
and allows players to personalize their car and the
way they play.
Life cycle/Support
During the development phase, the only users will
be the programmers

Developers will also provide product support
Developers will release the product on May 31st
We will support the game until the end of June

Afterwards, the company selling the game needs to find
people for support
As for the server side of our game, we will need
someone to support it after the game’s release



Make sure tomcat is running
Install new server software as necessary
Ensure server can handle all traffic needs
