(solved and intended)Custom Spawner with "MaxNearbyEntities" freezes

I was playing around with custom spawners but when I used the tag "MaxNearbyEntities" , the spawner froze and nothing happened...

What I expected to happen was...
... the spawner would just work as normal. It would not freeze and it would stop spawning mobs if there was already a certain amount of mobs around the spawner. (Just what the tag does, or should do)

What actually happened was...
...the spawner froze and did absolutely nothing.

How to reproduce:
1.Give yourself a command block and place it down.
2. Use the setblock command to setblock a custom mob spawner with the "MaxNearbyEntities" -tag.

/setblock <x> <y> <z> minecraft:mob_spawner 0 replace {EntityId:Zombie,MaxNearbyEntities:2}

3. Power the command block and notice that the little "mob" the spawner inside freezes, there are no particles and that is does nothing.

I've had this bug many times. I'm just not sure there is a specific way to reproduce it properly. Seems to bug out randomly.

However, in your screenshot, that spawner will not spawn any mobs since it's in full daylight.

Oh yeah, that's a shame... Accidententally made it day...
However, when I tried to make that spawner while it was night, it still didn't spawn any mobs. And this bug seems to occur randomly, I managed to get it to work a few times.

EDIT: If you add 'RequiredPlayerRange' the bug doesn't seem to occur.

Ah I missed that! This works as intended. You need that RequiredPlayerRange or there will be no tag to indicate when the spawner should actually spawn.

Here's a template

setblock ~ ~1 ~ mob_spawner 0 replace {EntityId:PigZombie,SpawnData:{Pos:[-463.5,5.0,960.5],Equipment:[{id:red_flower}],Anger:32000},SpawnCount:1,SpawnRange:50,RequiredPlayerRange:3,Delay:1,MinSpawnDelay:50,MaxSpawnDelay:50,MaxNearbyEntities:4}

Oh okay, thank you! Then this topic isn't necessary anymore... I'll remove it when I've figured out how 🙂

And I've got a question, how do you make a template like that or make the text bold or italic? <b></b> doesn't work...

qmagnet

Mods can marks this as works as intended.

The template is used was pasted inside {code } tags
