Why circles (and spheres)?

One interesting question is: "Why are circles (and by extension spheres) better for games?". I don't just mean computer games but a wide variety of games and sports use balls: marbles, billards, tennis, pétanque and football. Still more use circles: curling, shuffleboard and air-hockey.

On framerate

In recent discussions I've been involved in I've noticed that developers have a lot of ideas about the best frame rate for a game. Unfortunately many of those ideas are wrong, often for very straightforward reasons. As I've been thinking about this again for the game I've started I thought it worth a post on this.


The main point is there are only two frame rates you should consider: 30fps and 60fps. And 90% or 95% of the time you should choose 30fps. Why?

Buttons

This is a simple tip about how to do buttons in Flash. You can make them however you like, using code (as I usually do) or in Flash CS's editor. But always make them dynamic.
