Mobs not spawning in singleplayer world.

Open OverNamed opened this issue 6 years ago • 49 comments

In a singleplayer world at night, no hostile mobs are spawning even though I'm in hard difficulty. This has been since the start of the pack and has still been happening in 3.0.5 (the version of the pack I'm in currently.) I'm trying to get the shadow gem achievement done, but it's in every biome that they aren't spawning, not just darklands.

I'm using the twitch/curse launcher in 3.0.5, if there is a different launcher I can use, please tell me. I'm not using Optifine or any other types of mods, it's just the normal pack. http://prntscr.com/j222cg

The Url doesn't seem to work, if you can, please tell me how to fix it.

Just paste the raw link and do not use markdown.

Mobs spawn normally in my testing and for other uses. I cannot reproduce this. Make sure you're not playing in peaceful.

Darkosto avatar Apr 07 '18 20:04 Darkosto

It might be because I put in a seed instead of generating a normal world. But it still isn't working, I'll try to go to a new world without a seed.

OverNamed avatar Apr 07 '18 20:04 OverNamed

Yeah, when I go into a new world, without using a seed, mobs spawn.

OverNamed avatar Apr 07 '18 20:04 OverNamed

I'm having the same issue, hopefully it can be fixed

+1 for no hostile mobs spawning, just lots of wolves everywhere! i noticed that there are no red patches anywhere when i pressed F7 i didnt install optifine and also didnt enter a seed

runew0lf avatar Apr 09 '18 17:04 runew0lf

Same bug happening here, happening in all worlds, tried spawning worlds with preset/without, with seed/without and non of them are spawning hostile mobs made sure to progress to stage zero in all and still nothing. Have not added anything to the pack playing as provided. made sure all worlds were not in peaceful.

tomazak avatar Apr 09 '18 18:04 tomazak

@runew0lf When you say you pressed F7 and saw no red patches, where were you? On the surface outside? Underground?

Again, to add to this thread. I have tested on SP and MP personally. I've also talked to a number of players and not one of them is having trouble getting mobds to spawn. The issue people are experiencing here is currently unable to be fixed because I cannot reproduce it and neither can the people I ask to test. I'm not sure where to go from here since no one has been able to provide me with information as to what exactly is going on. I'll keep looking but there is nothing able to be done if I do not know the cause.

Darkosto avatar Apr 09 '18 18:04 Darkosto

Sorry darko buddy, outside in the dark there are no red patches. If you need any more information, let me know buddy and i'll provide all that i can. i dont have the world anymore as i wiped it to start again to see if i can get mobs to spawn tomorrow.

runew0lf avatar Apr 09 '18 19:04 runew0lf

This won't affect mob spawning, but just be aware red lines only show when the area does not have access to the sky. So, underground and covered areas will have red X's. Anything that is accessible to the sky will always be yellow.

I suggest reinstalling the pack, maybe something went wrong during installation? Also, what launcher do you play on? ATL or Twitch?

Darkosto avatar Apr 09 '18 20:04 Darkosto

I can't speak for runew0lf, but I'm having this issue through the Twitch launcher.

JakobBritton avatar Apr 09 '18 20:04 JakobBritton

I made a post about this issue on /r/feedthebeast and one user told me that they had the same issue, and they created a new world and instead of using the Sevtech v2 world option as they did in the previous world they left it at default and it was fixed. I tried this fix by recreating my world with default but alas the issue remained, but hopefully it will work for others.

JakobBritton avatar Apr 10 '18 00:04 JakobBritton

Maybe i'll say crap, excuse me if so. I had the same issue with no hostile mobs spawning at night and i started checking options... I toggled off the full screen option and the mobs came back... I know, it makes little sense.

I recovered at the same time the feature in JEI that highlight in the inventory the items we're looking for... I don't know if it's related.

Keradrimm avatar Apr 10 '18 10:04 Keradrimm

Ok what i said was crap... It went fine a couple of days... And now the mobs don't seem to spawn again... I don't know what i did. I'll try reinstall the pack.

Keradrimm avatar Apr 12 '18 06:04 Keradrimm

What render distance is everyone playing at?

Darkosto avatar Apr 12 '18 14:04 Darkosto

I'm having the same issue as well. My render distance is 8, I changed nothing when spawning a world. On rare occasion I'll see a zombie but I might as well be playing peaceful despite it being set to normal. I can run through a darklands at night and see nothing but neutral mobs and sometimes steppe wolves. It's making it rather impossible to get shadow gems.

Lance5057 avatar Apr 12 '18 15:04 Lance5057

It did fix it after starting a new game for me, i didnt change anything at all, exactly the same settings. (all default)

runew0lf avatar Apr 12 '18 15:04 runew0lf

I deleted that world after Darkosto said it wasn't reproducible. So I can't help dark out. Sorry

OverNamed avatar Apr 13 '18 01:04 OverNamed

I've done it from pretty much any render distance and nothing helped, I've tried redownloading the pack on the ATLauncher instead of Twitch this time and making a brand new world and I'm still having this issue. it's really frustrating because I just want to actually be able to play.

JakobBritton avatar Apr 14 '18 21:04 JakobBritton

I did after first commenting on this feed move from twitch to ATlauncher and i thought the bugged had been fixed although now progressing further i realises that it was only slightly alleviated, i play on render 32 didn't know this could effect the issue will try to lower it and see if anything spawns as i have the shoggoth quest and non spawn in their lair

tomazak avatar Apr 14 '18 23:04 tomazak

I'm also having this problem with a seed. I've spent 1-2 hours sitting in a darklands biome with nothing, and thought it was just getting unlucky. Then I noticed that I hadn't seen a mob in a while (there was mobs for a while) and I have seen 1 or 2 since. It's almost like peaceful, but mobs very very rarely spawn instead of never spawning, like Lance5057 said. It's making progression really tough. It's also worth noting that like others I see a TON of passive mobs, particularly steppe wolves. EDIT: I closed Minecraft and shut down my computer to sleep, when I rebooted it this morning mobs started spawning again. I don't know how long that will last, but it's worth noting I guess.

I had this problem, too when I used a different render distance than 12. With 12 mobs suddenly spawned in the darklands.

My steps to reproduce this (my version of SevTech is a bit different as Ive updated the mods and worked through any mismatch errors from them).

New Single Player > Preset: Sevtech v2; World Type: Realistic; Cheats, Structures and Chest on.

  • Age up as usual,
  • Receive message saying something akin to "Unlocked Mobs_zero"
  • Only see neutral elements--villagers, chickens/sheep/cows/horses.
  • Shogs spawn, but only after sitting in the lair for a sec. (I'd assume anything that is hard-coded to show up [shogs, TF bosses, etc] will appear)

Read the Preset potential solution, cloned the world, turned off the preset, and still no mobs.

Seed I was using was -4190587957783354985.

Started a new game with new seed, left the preset off, and it works just fine now.

@Darkosto this is related to the amount of memory available to java i believ , when memory maxes out, mobs stop spawning for some reason. If memory stays pegged 24/7 then the server never runs the spawn events. I have no idea why. If you want to reproduce, start a server instance with only 4GB then place a bunch of weirding gadgets in world to chunkload areas till ram usage is at max and GC is crying, then kill all and watch and almost nothing re-spawns.

Electrofried avatar Apr 26 '18 12:04 Electrofried

It is not memory related. I have had the same issue of hostile mobs not spawning in darklands, using 12/32GB of memory. As I found in another issue, a temporary solution was to lower Chunk view distance from 20 in my case down to 12. Mobs then spawned normally.

Myfistizpist avatar Apr 30 '18 03:04 Myfistizpist

Similar problem here, they spawn veeery rarely. Caves have no mobs. Darklands have only cows. Neutral mobs and wolves abundant, hostiles not so much.

kholat avatar May 24 '18 23:05 kholat

I can confirm @Myfistizpist 's solution, was wandering the Darklands at night and only wolves and non-hostile mobs spawing, lowered my chunks from 20 to 12 and now I have hostile mobs spawning.

Restarting the server fixed this for me

kryogenic avatar Jun 02 '18 07:06 kryogenic

All these solutions have one thing in common... They reduce the RAM footprint of minecraft, freeing memory. This is 100% a RAM issue, the one person saying they have 11/32GB used and still has the issue probably does not have enough ram actually allocated to the minecraft client/server instance.
