I'm working on a roguelike sequel to Maximum Overdrive where self-driving cars have paved the entire world because that's the most effective way to maximize fare revenue. Here's some level generator output:
I added a lighting system so that you could see a truck's headlight coming around a corner, but it's pretty hard to tell the difference between light emitted by the player and light emitted by the headlights. (I had to work pretty hard to find the situation shown in this screenshot.) I think maybe I ought to make the player not emit light and switch to a night vision sort of situation. Maybe the risk of trucks isn't to life and limb, maybe the headlights just ruin your night vision.
Okay, here's what's happening here, since it's definitely not clear just from looking at it: there are cars at a stoplight whose headlights turn red as they notice you. You lure it over to a supply crate that only cars can break. The circle that appears means you heard a loud noise at that location. You drop a cone so it gets stuck, then go up behind it, pick up the banana that was in the crate, then disable the car with the banana and recharge your battery from its battery.
This suburban neighborhood generator (filled with lawnmowers and doghouses) reveals two flaws in my visibility engine. One, in wide open spaces it has noticeable slowdown, and two, you can see a blind spot in the bottom right quadrant of the screen. That space on the screen never gets marked visible
