Need for Speed: Hacker’s TrailFan YangRich ChanCalvin ChungOutline Objectives Overview Modules Testing Division of Labor Timeline Possible ExtensionsObjectives Racing game with unique features: Users can create the racing track. Control the car with an “air wheel”.Overview 3 Main Components: Input: Interprets camera and mouse signals Logic Changes state depending on Input Output Displays game stateBlock DiagramMouse module The mouse module interfaces to a mouse connected to the labkit’s PS/2 port. This allows users to create their own racing tracks by moving the cursor of the mouse. At every positive edge of the clock the module receives data input from the mouse and provides the map module with the x-y coordinates of the mouse cursor.Hand-finder & Hand-logic Modules The user controls the direction and the acceleration of his car by moving an “air wheel”. To detect the motion of the wheel, the user will wear colored gloves and steer the wheel in front of a camera. Hand locations are determined by center-of-mass algorithm. Height of wheel acceleration of the car Angle of the wheel rotation of the carGame Module Interprets user inputs sent from the input module (accelerate/decelerate, turn, etc.) Continuously computes new vehicle states from previous values (velocity, position). Keeps track of game state (laps, times, etc.)Collision Module Given the car position and angle, check for whether the car has collided with the track. For each point that the sprite will occupy, check if both the corresponding pixel on the map is filled.Map module Stores map using 512k*36 BRAM Edit Mode: Loads empty map on reset. Creates a circular blob for each mouse position sent in from the mouse module. Real-time map display through graphics module. Play Mode: Displays map through graphics module. Sends in color of particular pixel to collision module per request. Need dual-port to read and write at the same time.Sprite Module Stores car sprite in module. Interacts with collision module (Play Mode): Rotates sprite based on car rotation angle from collision module to check if particular coordinate given by collision module is within car boundaries. Interacts with graphics module (Play Mode): creates sprite based on car position and rotation angle.Graphics Module Produces video output Edit Mode: Displays map real-time as track is being drawn Play Mode: Displays map from map module. Receives car position and car rotation angle from game module to create car sprite through sprite module. Displays car sprite on map.Testing Modules are tested individually before the system is tested as a whole We can simulate the input for each module and observe their outputsDivision of LaborInitial Division Input modules : Fan Yang Control modules : Rich Chan Output modules : Calvin Chung After the prototype is done and each part is tested, we’ll start working together in making the game better as a whole.Timeline 11/28. Basic working prototype. 12/02. Refine prototype. 12/05. Extensions added. 12/07. Project wrap-up. 12/10. Finish project report.Possible Extensions Adding multiplayer support (1 v 1 games) Adding interesting behaviors when the car crashes into the track boundaries. Adding audio
