Little glowing green stick figures, in the spirit of Darwinia, stroll
the streets: each walks toward a random reachable point in plain sight
on the navigation grid, pauses, and about a third of the time heads
toward a nearby resident instead, so they gather in small crowds. They
are camera-facing sprites drawn procedurally in the fragment shader
with a walk cycle, flicker and halo, grown with altitude so crowds stay
visible from the helicopter, and fogged like everything else.
About one resident per 2,500 m² of city (40 to 600), spawned only on
the city's own streets. Because they keep the city animating, Settings
has a City residents switch (saved with the other preferences). The
simulation is seedable and tested to keep everyone on walkable ground.
