> "if walk monster manually trolls the map" Casey Muratori has a 50 minute video on "Killing the Walk Monster" which is about how they started looking for glitchy game geometry by pretending to be a player walking around, then by a flood-fill ("walk monster") probing for barriers, then the video is explaining how they designed something "exponentially faster" (both demonstrated starting at time 38:33). The better version was realtime enough that level designers could use its overlays interactively while working on the level, and during test playthroughs. He describes it as "exponentially faster". It doesn't seem like the earlier poster calling it "brute force" is a reasonable description. https://www.youtube.com/watch?v=YE8MVNMzpbo https://www.youtube.com/watch?v=YE8MVNMzpbo And the place the player can walk but shouldn't be able to (off the boat), is not a fault in the walk system, as explained in that video near the end, it's a place where level designers made a mistake.
