The idea is to just finish a project, learn from it, and move on. At least with the project I made. Better physics simulations will come along down the road in the future, and I'm sure I'll write about them when I get there.

This frequently causes difficult to debug problems, including problems with numerical stability (what if the computer is 1000x faster than your desktop? what if the timestep is very large?) A variable timestep is a nightmare for programming for other reasons as well (what if two events that are supposed to happen at different times happen at the same time?) I can't think of a single good reason to use a variable timestep in a game.Anonymousnoreply@blogger.com
