Project Overview

• Goal
• Develop an action arcade game
• Using
• Visual Studio .NET 2003
• 3D Studio Max 5
• Photoshop CS / Illustrator CS
• Cool Edit Pro

3
Why

• Simple but contains many of the elements of game
  development
• Rendering of graphics
• Collision detection
• Collision response
• Sound
• Particle System
• UI

4
Requirement Categories

• Basic
• Three side walls and a void
• A paddle and a ball with no acceleration
• Breakable objects in the middle area
• Power ups
• Sound effects
• Mouse input
• 1 game level and 1 difficulty level
• Basic collision detection
• Collision response

5
Requirement Categories

• Enhanced
• Basic plus
• Floating objects to provide more challenging
  environment
• Curved spline for the path of the paddle
• A paddle and a ball with acceleration
• Floating objects that regenerate as time passes
• Paddle with missile as a power up
• Up to 5 game levels and 2 difficulty levels
• Background music
• User Interface (menus, score, etc)
• Particle effects

Almost a game
14
System Design Simplified game flow

• Setup controls (UI)
• Load level entities
• While ( !quit )
• Process input (if it exists)
• Update game entities
• Render game
• Render UI (score, balls left)
• Cleanup
• Exit

15
Algorithms Collision Detection

• Each objects bounds will be defined. Collision
  detection occurs when two or more bounds
  overlaps.
• Between two circles
• fDistance Distance between the center of the
  circles sum of radius
• If fDistance is lt 0, the collision is detected.

16
Algorithms Collision Response

• Between two circles

Moving ball
Static circle
17
Algorithms Collision Detection
This is a valid collision as the circle is moving
toward the line. It is detected by taking the dot
product of V and N. If it is lt 0 then, they are
colliding and the collision detection begins by
comparing D with the radius of the Circle. When
D lt radius, collision response starts.
18
Algorithms Collision Detection

• In this case the dot product of V and N is gt 0
  which indicates that the ball is behind the wall.
  No collision detection is required. The use of D
  and V for the dot product would allow a double
  sided collision. Single sided collision is needed
  because discrete collision detection could allow
  the center of the ball to pass through the wall
  making it seem like the ball is on the other side.

Algorithms Particle Systems

• Particle system is used to simulate explosions,
  collision impacts, and smoke trails.
• What is it?
• Made up of particles
• A particle is a small object, a triangle in this
  case.
• Properties of a particle
• Position
• Velocity
• Color
• Age

Conclusion

• The project was a success. It was challenging
  but covered many useful aspects of game
  development and computer science.
• I have begun to learn DirectX, 3DStudio Max, and
  Cool Edit Pro.
• Download my game and try it out.
