Suggestion: starting city destruction

[ogoid]

Isn't funny that the vehicles start damaged, but the towns neat and clean?

How about creating new worlds with some broken windows and doors, collapsed buildings, trash, blood and other signs of earlier chaos?

I think vache was working on something like that a long time ago. I get angry when I try and understand the mapgen code, so I can understand if he has yet to complete his PR.

[kevingranade]

Definitely something we'd like to see, a good way to do this would be a
method in the master mapgen function that randomly applies some different
effects to submaps after generation.
An even cooler thing I've been trying to figure out would be to patch
something into both overmapgen and mapgen to apply large-scale
modifications to a swath of several submaps. During overmap generation, it
would pick a number of contiguous tiles to apply an effect to and mark
them. During mapgen, if it generates a tile with such a feature, it would
trigger loading of the connected subsmaps, then apply post-processing to
all of them.
The specific hook would go in map::load, if it detects the submap hasn't
been generated, it can check if the submap is marked for a feature, if so
it would trigger loading a map with dimensions equal to the size of the
feature, and then it could operate on that map as a whole.
Examples of large scale features: a very large bomb crater that overlaps
submap boundaries. A long stretch of rubber laid down on a road, with a
car wreck at the end.

I don't know where it is, but don't we already have this? I've seen lava cracks in random buildings, and large areas of rubble, etc.

[Rivet-the-Zombie]

Yeah, but Vache's plan was for buildings to sometimes have blood/damage on them, broken windows/doors, smashed furniture, being partially burned, stuff like that.

We'd likely have it already if not for the fact that the PR got bogged down by the addition of a bunch of similar, but unnecessary other stuff, like pre-triffidized buildings and such.

[kevingranade]

The existing code overwrites terrain like a giant stamp, the proposal is to e.g. turn walls to rubble so it looks like a partially wrecked hous instead of a big hole in the ground.

[sparr]

I'm confused. I swear I saw a garage with a lava fissure through it, and I assumed "add a lava fissure" was an overlay somewhere.

[Zireael07]

Umm, linky to vache's PR? I know which one is being discussed here, but can't find it, search is not up to par.
I'm sure Coolthulthu or acidia could restart the idea in a cleaner way :)

The original PR in question: #7892

[MattAmmann]

@sparr The lava spawning inside buildings is a map extra. I actually had this same question not too long ago: #11393
