##Intro Revolutionizing the brick breaker genre. With innovative techniques meant to spur a new kind of gameplay in the 3D realm, check out our new amazing features such as collision detection, Phong shading and multi-geometry instantiation.

Play it Here!

##Actual Intro Our group made a a brick breaker like game in 3D. Levels include normal bricks, metal bricks, ice bricks, tree bricks, and fire bricks. Left/right keys are the main keyboard control and everything else should be easy to understand. Levels can be manually changed to 1-5 by pressing the corresponding keys on the keyboard.

##Key Commands

• S - toggle music
• Spacebar - launch ball from paddle
• Left/Right - move the paddle
• 1/2/3/4/5 - view main level layouts
• N/W - narrow/widen FOV
• I/K/M/J - move view north/east/south/west
• R - resets the board at the cost of a life

##Advanced Topics

• Physics

  • The ball bounced off bricks and walls at the proper angle
  • The ball bounces off pad at correct angles
  • The ball changes it angle and velocity if the pad is in motion when collision happens.

• Collision Detection

  • Collision Detection is tested between ball, bricks, wall and pad.
  • There is spherical detection for the ball and cube detection for all other objects

Topics Implementation

• Lighting
  • We used phong shading on the ball with the pad as a point-light source. At the start of the level, you can move the pad to see the changes on the shading of the ball
• Texture mapping
  • Bricks, pad, and wall are all texture mapped.
  • Repeating texture is used on the wall while other textures are applied 0 to 1.
• Camera motion
  • Camera motion is kept from the previous assignments except left/right are now for moving the pad.
• Transformations
  • Spheres, walls and pad are transformed throughout the level.

Programming Decisions

• Multiple texture of bricks can exist in the same level but only one is applied for bricks at a time for better aesthetics.
• LevelDef.js defines the board definitions and initLevel processes the initialization of levels.
• When colliding with two cubes, the ball can exhibit strange behavior. The fix for this is to pause collision detection for a small time and also default to having the ball move down upon complex collisions.
• Score display is implemented in html fill text.

Extras

• All of the music, sounds, and textures were original.
