What goes into making a game? Game Design : Levels, stories, characters, rules Game Development: – Media : Art, models, music, sounds – Programming : Computer code

Starting Small Games come in lots of sizes Size != quality Start small

How do we make small games? Small means as little work as possible: Art: – Simplify Sound: – Use freely available sounds Programming: – GameMaker simplifies coding Game Design: – This is where the time should go

First Game

Gamemaker basics Gamemaker building blocks: – Rooms – Sprites – Objects – Events – Actions

Rooms A room is a level, or – Loading screen – Inventory screen The one thing you HAVE to have

Measuring Measurement in square called pixels. Location, given with x coordinate (how far side to side) and a y coordinate. (how far up or down). y x

Measuring Upper left corner is x = 0, y = 0 x = 400, y = 100 y x

Origin Every sprite has an Origin – center of sprite Duck placed at 0, 0 y x

Relative Measuring Relative values are amounts to +/- from a starting point Bullet hole is: -150 x, -200 y Relative to duck

Relative Measuring Bullet hole at -150 x, -200 y Absolute coordinates

Directions Directions in degrees – 0 degrees means to the right on your screen – 90 degrees is up – 180 is left – 270 is down

Sprites & Objects A sprite is a picture An object is something that appears in the game

Instances Objects are a template to make instances. – Object = cookie cutter – Instance = cookie

Events & Actions Events are chances to make objects respond Actions are the code to say what object does
