Yeah, a fire that spreads in a circle can still be mapped onto a grid. We just need to discretize the circle into grid cells and make sure the evacuation route follows the grid lines. Show me the sketch, and I’ll check the spacing and intersections. We’ll tighten up the tweaks so every exit point sits on a clean grid line and the distance between steps stays uniform. It’ll be a tidy, predictable path, even if the blaze is a bit chaotic.

That’s a solid start, but a couple of things need tightening. First, make sure the dotted perimeter actually lands on grid lines; otherwise the “burned” boundary will be a fuzzy line, and the exits will be off‑center. Second, a straight‑line step of exactly two cells is fine only if the angle between exits stays a multiple of 45 degrees; otherwise the line will cut through cells diagonally and break the grid rule. Place the dots so each segment is a clean horizontal, vertical, or 45‑degree diagonal hop. If any corner ends up with a half‑cell offset, shift it back to the nearest full grid line. Once that’s done, the evacuation path will be a flawless sequence of perfect steps.
