|0007698||Dwarf Fortress||World Generation -- Beasts||public||2014-07-28 13:31||2015-12-10 17:08|
|Platform||x86_64||OS||Windows 7||OS Version||SP 1|
|Target Version||Fixed in Version|
|Summary||0007698: Excessive numbers of underground critters|
|Description||Medium world, 0.45|
Underground Animal Populations (Including Undead)
95334 giant cave spiders
196464 naked mole dogs
253515 giant rats
276402 giant cave swallows
There are more Trolls than every civilized race together. Gorlaks are the real rulers of the world.
|Additional Information||It looks like some change made the reproduction of underground critters to hit absurd levels. This may have an impact on performance.|
|Tags||No tags attached.|
|I meant "0.40.05" instead of "0.45"|

Related to or a duplicate of bug 0007673.
And it might be intentional. Not only are there three cavern layers to the one surface layer, but *everywhere* underground is suitable for underground creatures, whereas civilized creatures don't live in the middle of mountain ranges or out in the ocean.
This one has more useful numbers, so I'm marking the other one as a duplicate.
The numbers don't seem that outlandish, unless they're all spawning on the local map at once. Can it be shown to impact performance?
This is likely intentional. Previously it was easy enough to kill the entire population of wild animals in the world through deploying enough hunters. This seems a bit absurd. Yes, any troll that wanders on to the premises of your fortress is probably doomed. But this doesn't mean every troll is doomed. Trolls will continue to reproduce "off map" and will wander on to your map.
I believe this was done to ensure that your hunters would be viable even after many years of hunting. Animals will reproduce elsewhere and will migrate on to the map to keep your hunters busy.
Now if you had some 299,000 trolls all show up on your fortress at once, then yes, you've got a problem. But if they're showing up in small numbers at a time I don't think there will be any issue.
Animals, yes, but inteligent critters?
Same world as above:
26 grizzly bears
57485 blind cave bears
Maybe there isn't a performance hit, but it is very strange.

The release notes for 40.05 specifically address this:
"Made underground populations properly respect layer size (the numbers can get very high, but blame the giant under-ocean caves in part)"

If we say there are 26 bears aboveground, and assume that's a decent population... And then we assume that this is an archipelago world with 3/4 of the map covered in water, and we assume that there are the standard three cavern layers, then that's 4 * 3 * 26, which comes out at 312. 57485 cave bears is just so far from that that it's ridiculous to assume it's normal, I would think.
It would make sense if there were about 400 bears above ground, though.

The issue remains in 0.42.11. While we have usually only a dozen or so aboveground critters of a given species, in the underground and on the seas species amount to the hundred of thousands. While it may (or may not) have an impact on performance, these numbers damage the coherence of the world. This could be solved by making some critters endemic to a region instead to all over all the biomes in the world (like in the real world), to create different biomes underground and in the seas (coastal, island, deep sea). I know this is suggestion territory, but it would be nice to know if in fact there isn't some kind of bug in these numbers.
Some medium world created in 0.42.02:
114636 giant cave spiders
518397 giant moles
156604 helmet snakes
238342 naked mole dogs
747272 elk birds
193329 giant bats
217782 gigantic squids
2589186 giant horseshoe crabs
2024925 giant sponges
7 leech men
