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

6. 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

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

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

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

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

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