A game by Gravity Pole Productions Graham Pentheny, Tim Volpe, Ryan LaSante http://www.wpi.edu/~pentheny/nbr/

Game Premise “Reverse-platformer” User Generated Content You make the level, AI does the character control User Generated Content “Notebook” feel

What Worked: Level Design & File Format Physics AI Making JME 2d Drawing Gameplay

What was a little skittish: HUD (120d curse strikes again) Moral: Tutorials aren’t always right… Collision Detection (HACK HACK HACK) User generated Geometry makes this much, much more complicated. Menus w/ FengGui

What Outright Didn’t Work Level Editor Try to script new object behavior @_@ Add to FSM Manual level design works fine. Text files ____.lvl

Making JME to work for us 2d Fix camera movement to x and y axis Game States Level Objects Art HUD Don’t use Java2d ;-)

Drawing Recognition Get mouse coordinates at specific intervals Place geometry between points Get level object Do recognize Place object in scene…or not

AI, Physics, and Collision Detection OO-FSM (yay acronyms) Each has velocity, acceleration Bounding Boxes (Extrude in Z) Sends type to FSM which changes char movement Decoupled from Framerate <3 2d physics <3 Acceleration, Velocity, Position – Vector2d this.position.add(this.velocity.mult(deltaTime)); this.velocity.add(this.acceleration.mult(deltaTime)); this.acceleration = this.theAI.currentState.getAcceleration();
