Quack Attack! the saga begins A game by Ryan Sullivan
Overview Why make a game Storyline Design Problems Screenshots
Why Make a Game? Something I’ve always wanted to do More fun than previous projects Graphics programming Uses concepts learned in CS courses
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 don’t know what happened to them
Storyline Game entrance –You enter game as a newly hatched duckling –You know nothing about your parents death –You are alone in the pond
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 –It’s pretty much most of my class design
Tree Data Structure
Disjoint Sets Used to generate a maze Every maze cell is it’s own set Disjoint Sets randomly selects cells and checks if they’re in the same set If not, it combines both sets Keeps going till all cells are in one set
Bounding Box Collision Detection
Game Mode Big If Statement There’s 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
Game Mode Input
Game Mode Input - Playing
Game Mode Draw
SimpEngine Layout
Tree picture (again)
Problems SimpEngine a blessing and a curse –Almost no documentation –No “how to do this” –I’d spend lots of time trying to do something, then realize there’s a much easier way Phantom Errors Time – ROTC Senioritis
