Why Make a Game?

• Something Ive always wanted to do
• More fun than previous projects
• Graphics programming
• Uses concepts learned in CS courses

4
Storyline

• Background
• You are a duck
• Your parents lived in a small country pond
• They were killed by a cougar just before you were
  hatched
• You dont know what happened to them

5
Storyline

• Game entrance
• You enter game as a newly hatched duckling
• You know nothing about your parents death
• You are alone in the pond

6
Storyline

• Pass various levels (only two in The saga
  begins) to gain clues about what happened to
  your parents
• In Revenge of the Duck (not part of this
  project) you actually confront the evil cougar

Design

• Data Structures/Algorithms
• Tree
• Disjoint Sets
• Collision Detection
• Game mode
• SimpEngine
• Simple Graphics Engine
• Its pretty much most of my class design

Tree Data Structure

Disjoint Sets

• Used to generate a maze
• Every maze cell is its own set
• Disjoint Sets randomly selects cells and checks
  if theyre in the same set
• If not, it combines both sets
• Keeps going till all cells are in one set

Game Mode

• Big If Statement
• Theres several modes, including
• Main Menu
• Load Level 1
• Level 1 instructions
• Playing Level One
• Easy to add new modes
• This allows me to turn off key/moue input based
  on game mode
• This controls what is drawn

Problems

• SimpEngine a blessing and a curse
• Almost no documentation
• No how to do this
• Id spend lots of time trying to do something,
  then realize theres a much easier way
• Phantom Errors
• Time ROTC
• Senioritis
