master plan of obtaining massive amount of fortune have just started a job as a delivery boy for the Jimmy Johns Gourmet Subs Cooperation Unfortunately you ve had the luck of becoming a delivery boy at one of the stores located in Ann Arbor Michigan One of the most difficult cities to deliver in Known for its bad drivers random one way streets and of course jaywalking pedestrians that rarely look before crossing it can be a delivery boy s nightmare It is your goal to keep your employment with the Jimmy Johns cooperation so you can accrue enough wealth to own the free world Game Play The game is an overview 2D game The goal is to successfully get the car to the delivery goal within the specified time period If successful the player earns tip money which is then added to their total savings While out delivering the player must avoid hitting parked cars If they happen to come in contact with a parked car it will cause damage to their car If the player s car gets 100 damaged they can no longer deliver subs and the game ends If they finish their delivery without obtaining 100 damage they can apply the money they have saved or earned to fix their car The goal of the game is to save up as much money as you can Each level is randomly generated everything except the map to mimic the actual delivery environment where you have what seems to be random delivery times and random delivery locations Because this takes place in Ann Arbor parked cars are randomly placed on the streets to represent the way people park where every they feel like parking Development Specifications The software will be developed in Visual C 6 0 with DirectX The parts of DirectX will be Direct3D DirectInputs A digital camera will be used to capture any needed graphics for the game play Photoshop 7 0 will be used to manipulate any of the images so a contiguous virtual world can be created Camera Position The camera is located at an over head location looking downward towards the ground The camera will remain in a relatively fixed position When the player s car is near a boundary of the world the car will be moved instead of the camera to provide the illusion of an end of a world Otherwise the car will be centered on an axis x or y and the background screen will be moved The view of the camera position can be seen in the Game Play screen located in the Interface Design portion of this

Screen The game play screen consists of five main elements First is the player s car This is the white car in which the camera follows around This is the object the player controls The next are the blue cars These cars are the parked cars that the player must avoid These cars appear on the road through the world map Next is the directional arrow This is a yellow arrow that is always on the screen and located in the lower right hand corner of the screen It represents the direction that the delivery location is from the car s current position in the world The next two items are the time remaining in the level and the total amount of damage the player s car has obtained When the remaining time is less than 15 seconds the text turns a red color to bring attention to the user The car damage indicator also turns red when a damage rate of 80 is obtained Replaying and Saving There is no mechanism for replaying or saving Just as in real life if you don t make a delivery you don t get
