The document discusses the importance of math in game development, emphasizing that only basic concepts like algebra, geometry, and trigonometry are necessary. It explains procedural generation techniques used to create dynamic game environments and balance difficulty through various obstacle and collectible generation methods. The document also highlights the significance of game balance and randomness in creating engaging gameplay experiences.

- 2. + Truth #1 n Not everyone loves Math </3
- 3. + Truth #2 n Game Development needs Math… tons of it
- 4. + Truth #3 n You only need to know the simple side of Math
- 5. + What’s the simple side? n Algebra n Geometry n Trigonometry
- 7. + Procedural Generation n Algorithm to “create” things on the fly n Used for n Backgrounds n Goodies n Baddies
- 8. + Endless Backgrounds n Scrolling flat n Dynamic scrolling flat n Parallax effect
- 9. + Endless Backgrounds n Manipulate tileable texture as a function of time and/or input
- 10. + Pattern Generation n Predictable n Random
- 11. + Pattern Generation n Uniform Spacing n Non-uniform Spacing
- 12. + CholesteRUN Demonstration of Procedural Obstacle Generation
- 13. + Goodies and Baddies n All segments have the same length n Each segment has… n reserved Cholesterol locations (25%, 50% and 75% of length) n reserved O2 locations n assigned Power Up locations n Not all segments are the same n Some segments have a max of 2 cholesterol locations and only 1 O2 location and 0 Power Up locations while others can have 0 cholesterol locations, max of 3 O2 locations and 1 Power Up location
- 14. + Baddies Generation n The game has a difficulty setting based on time n Actual obstacles generated is capped by max obstacles that the segment can handle Difficulty Duration Max Obstacle Easy 30 1 Medium 60 2 Hard - 3
- 15. + Goodies Generation n Oxygen come in sets which occupy 1-3 O2 locations
- 16. + Mixing n Some segments are… n fully randomized n partially random, partially predictable n fully predictable n Not all obstacles have the same length. Special obstacles occupy more than 1 location or would make the game too difficult if they’re combined with other obstacles
- 19. + Limitations n Occasionally, the O2 lead you to the obstacle n Games with fully randomized obstacles tend to be very difficult! Game Balance is important! n Randomization has the possibility of repeating, but this can be easily fixed
