説明

When you click a building with people inside, they currently appear, but their arrangement is a bit silly (and sometimes leaks outside the building). It'd be fun to improve this, and it's pretty self-contained. Code is at https://github.com/dabreegster/abstreet/blob/3eecdeddff70bbca2fb36f6e1bb0ef634fe01cf1/game/src/info/building.rs#L182. Some ideas:

  1. From the building outline, procedurally generate a floor plan
  2. Move people around inside the building slowly to represent activity inside. This should be a very cheap calculation, not a full-blown simulation or anything requiring storing any state. Ideally you take as input (sim time, person ID, the building) and come up with a position.
  3. Maybe allow mousing over and clicking people inside buildings. At least one person during user-testing was surprised you couldn't.

調査方針
Start by examining the code in game/src/info/building.rs to understand current person placement. Review the procedural generation ideas in the issue, particularly generating a floor plan from building outline. Look into similar algorithms in other projects or simple geometric approaches. Consider the constraint of cheap calculation as stated. Also check the comments on the issue for any additional context.
