The other aspect of LÖVE's Body class is that critically bodies can collide & interact! Incurring impulses to apply as described yesterday. How'd reimplement this upon our Lua machine?
Checking whether any 2 given bodies are colliding is trivial for the computer: 4 comparisons if we're talking bounding boxes.
Things get slow & complex when we ask "which of these bodies are colliding?" & "Was it between frames?"!
1/3?
