Thanks a bunch for the encouraging feedback! I wonder where this project
might end up.
Shawn:
The bottom-left numbers read (from top to bottom): number of drawn
primitives, seconds per frame, frames per second.
For example, if you evaluate
;; Add a gentle but slippery slope
(space-add space
`(body ((static 1))
(segment (friction 0.1)
(endpoints ((250 500)
(800 550))))))
You should see the primitives go up from 48 to 49.
