How can I derive force vectors from velocity vectors?
- by PixelRouter
I'm making a 2d shooter ala Geometry Wars. I've got my own simple physics at work driving the background grid and all my entities. To move anything in the world I apply a Vector2d force to it. The 'engine' calculates the resulting acceleration and therefore the velocity.
I am trying to port some code I found which implements the classic 'Boids'…
