[2024.4] "Creatures" don't spawn, but "ambient" works?
Fri, 01/31/2025 - 16:19 (edited)

Hi guys,

 

I'm trying to add a custom mob to a 1.21.1 mod that I'm working on, but I cannot get any custom mobs to spawn at all.

If I add even the most basic mob, which I can spawn in with an egg, it will not spawn when the spawning type is "creature." I've tried:

 

  • Setting the spawn weight to as high as 1000.
  • Unlimiting the biomes.
  • Setting the biomes to the minecraft:is_overworld tag.
  • Default animal AI.
  • No custom triggers.
  • No animations.

 

I cannot get it to work at all. Any advice?

 

 

Update: I finally managed to get them to spawn, but it is incredibly odd, and I'm likely missing something. They only spawn at night, and even then, it has to be even darker than that, so they almost exclusively spawn under trees.

Update:

I've finally managed to make them spawn, but only in groups of 1, despite explicitly stating groups of 4, and it's incredibly rare. Like, 20 minutes flying around typing /tp @e[type=lumens:money_beetle] ~ ~ ~ before I found a naturally spawned one.

 

Again, the actual spawning weight does not seem to have any baring on this at all.
