# More game math

By Murray Bourne, 15 Aug 2007

There is a Flash game competition on at JayIsGames. Participants need to incorporate the theme of **ball physics** into their game.

Ball game mathematics includes the following topics (with links to related chapters on Interactive Mathematics):

- Trigonometry, including inverse ratios
- Vectors
- Cartesian Coordinates
- 2D and 3D geometry
- Pythagoras' Theorem and Distance formula

One guy has started on his competition entry entitled Throw a ball with a sling. The article includes a tutorial on how he is incorporating mathematics into his game.

There is an extensive article on Gamasutra called Pool Hall Lessons [no longer available], which gives a good insight into some of the mathematics used in computer ball games.

Let the games begin.
