Game Engine Progress
By Eric Fletcher and
Derek Keola Ng
Intro
Progress
 Controls updates
 Class Structure updates
 Timeline
 Current Status
Controls
• OIS – Object Orientated Input System
• Details : http://code.google.com/p/flightsimrpg/wiki/InputSystems
• Throttle and Yoke System
• Used in MS Flight Simulator X
• Buffered Input
MS Flight Sim X Demo
Buffered Input
• A stack of inputs at one time (frame)
• keyPressed & keyReleased
• Advantages
• Increase efficiency
• Simulate plane steering
• Can stimulate unbuffered input if needed
Controls
• Throttle button
• Adjustable?
• Break
• Directional Buttons: Yoke
Progress
 Controls updates
 Class Structure updates
 Timeline

Class Structure
(subject to change)
Class Structure
• Plane and Robot class
• Plane.h
• Robot.h
• Why?
• Main Focus
• Track game data
Examples
•
•
•
•
•
•
•
Position (x,y,z)
Speed
Axis/Rotation
Damage
Plane Fuel
Parts
Function calls
Function Implementation
• Game Engine: What/Where
• i.e. position, axis, tilt()
• Physics: How
• i.e. tilting 5 degrees in tilt()
