Wolf Pack spawned inside my chicken coup

[Lingam]

Hey there,

 

Just today I saw something moving inside my closed chicken coup... went over and found that I lost all my chickens to a pack of 3 wolves 

How can they get in without opening the gates? The whole chicken coup was closed in obviously so the chickens cant get out..

Bummer!! That hole in the upper left I had to make to shoot the wolves, I couldn't shoot them through the open gates, it would just close the gates

was or is there a roof (can't tell from the screenshot)

think adding a light source will prevent the mob spawns

pretty disheartening, feel like it takes forever to raise chicken generations

Winner, winner, chicken dinner.

Spoiler

They will spawn only at light level 7 or below.

Man, that's annoying.  You won the lottery of bad VS luck.

Yes, the roof was made of smashed dirt and I had about 5 bowls with fat (lights) all near the ceiling keeping the coup lit

I did get lots of feathers and chicken dinners..

Lamps are only brightness 11, so the floor 2 tiles below the lamp is light level 9. The coop looks to be, what, 9x12? If they are all wall-mounted, they only spawn-proof the 2 outer tiles, and that's assuming  you have them every 3rd wall section, so around 12 lamps. And of course, the center 5x8 is not protected at all.

If you put the lamps on the floor, you get by with far fewer -- a lamp in the center of a room spawn-proofs a 7x7 area.  To get almost the same area, tow lamps would light a 7x14.

I'll try this thanks.. maybe next spring. I will have to rebuild this... I attracted the chickens and a few elk on accident into a 2 deep pit, then built around them.

I'm naming it my Wolf-Spawn cage now...

After killing those wolves, later another wolf and two pups spawned in there and I keep farming them as they grow for meat, fat and hide...

Might as well keep killing the buttheads that killed my chickens!

Nice. I've yet to see someone explain how mobs spawn in the world. I've noticed that there is a high chance for wolves and bears to spawn in almost the exact same location over and over. Yes, people have posted the line of code that gives the % chance of a mob spawning, but that doesn't explain why the same spot over and over. The spots I've noticed aren't even forest.

[Thorfinn]

A small enough "forested" region as defined by the mapgen does not necessarily spawn trees. It just sets the percentage chance for a tree to be generated. RNG can still end up without spawning them.

Offhand, I think it only requires a 20% forest, so if you cleared a small copse of a half-dozen trees on an otherwise treeless plain, that maybe the ONLY place with sufficient "forestation" to spawn them. And, yes, that's exploitable, if you take the time to analyze terrain first. It's also possible to find plains where the only place sheep can spawn is one smallish hill.

[Zane Mordien]

I've had places like that before, but this map for example.. which is an older map in 1.19. I had to kill wolves almost every day for 15-20 days. There was plenty of forest around so I never understood why this spot was the spawn spot. I would go in my little house at night to pan sand and bony soil and start hearing the howls.

There are 2 places just a little further south in the gravel desert that always spawn a bear. I used to nerd pole and kill them, which is why I know the bears were always in the same spot. They would be right next to my old nerd pole every time.

[Thorfinn]

I don't know. I never cared about spawn mechanics until 1.20. I was primarily trying to figure out why bowtorn were apparently spawning in groups rather than by the each. When nothing else was behaving the same way. Could well be that was a related bug. Just because it gets passed properly does not mean that subroutine is also working properly. Though, again, weird. Why wolves and not, say bunnies?

I did check really quickly, and wolves require 50% forest. I have no idea how much you have chopped out, but there are not a lot of places on that map that look like they would qualify.

They probably did somewhere, I just never notice piles of bunnies.

"Found your problem. It aint got any gas in it!"

Just messin. You need light. Consider adding lanterns, then adding silver plate to your lanterns to make them even brighter.

[BearWrestler]

Blergh. This is why I can't really come back to playing this game. Crazy nonsensical wolf spawns have been a problem since forever, and seemingly (?) zero improvements have been done. Now I bet bears and mod-added animals have the same problem.

Seems to me wild animal spawns should be prevented by a combination of a heatmap of player activity (you leave your "scent" on blocks you visit and nearby blocks, it's stronger the more often you pass by) and local concentration of 'civilized' blocks - i.e. blocks that are seraph-made and don't typically generate in the world.
Light works well as a spawn mechanic in Minecraft because it's dead-easy to blanket the area in torches that last an infinite time... not so in this game.

[JAGIELSKI]

I think spawning in general should be removed (aside of the initial spawning during generation of a chunk). The animals should otherwise look for mates and breed on their own. It also would allow for stuff like extinction via overhunting (either purposeful or accidental) and with you leaving certain population alone it will eventually grow into a sustainable food supply without you having to do any real work..

[RobinHood]

As an alternative to light, I would also replace normal soil blocks with quarry stone blocks, wooden blocks, compacted soil, soil with straw (blocks).

It looks more natural when animals live on earth blocks / grass blocks. But so far a hutch without natural soilblocks and lots of light is the safest.

[Thorfinn]

Maybe. Someone (maybe @Ryan Thomas ?) posted a few screenshots of goats that apparently spawned in his contemporary house. I think he said he had not yet added the lighting, but the floor was definitely not dirt.

Ok, I have wrote a suggestion in discord
