Some entities are displayed outside of their spawner

MCEdit does not make it invalid because MCEdit is not a mod.

Is this still a concern in the current Minecraft version? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.

Confirmed in 13w11a.

Also confirmed in 1.5.

this also works with giants 😃

Affects Minecraft 1.6.2, 1.7.4 and 1.8 snapshots (06b)

affects 07a

Confirmed for 1.7.5, 14w10c and 14w11b

Confirmed for 14w17a
Tested with this command:

/setblock ~ ~ ~ mob_spawner 0 replace {EntityId:"Ghast"}

Blah, I just tested this in 14w30c and it's still broken.

In creative, I right-clicked on a spawner with a ghast egg. The ghast is still displayed outside of the spawner.

Still reproduceable in 14w32d!

Still in 1.8

Confirmed in 1.8.3. The issue is that the size of the mini-mob inside of the spawner is scaled down by a fixed ratio, no matter the size of the original mob. This not only leads to mobs like ghasts, withers, giants, and endermen extending outside of the spawner block, but also makes very small entities like XPorbs and bats render much too small. Additionally, since the center point of mobs is their lowest block, but regular sized mobs are supposed to be centered in the spawner, the spawner actually puts the center point of the entity much lower than the center of the spawner block itself. This means that entities that are smaller than regular sized mobs render much too low.

Ghast are way too big. Slimes and Magma Cubes are a little bit too big. (depends on the size of the slime which is random) and endermans too long..

Confirmed for 1.8.9 and 15w51b.

Please re-open.
In 16w02a it still affects (at least) endermen.

still effects witches (hat just out), enderman and giants (I know they are unsupported, I'm just mentioning them anyway)

Reopened and given ticket to @unknown. Please update it.

For Giants it might be intended as you are maybe unable to tell the difference between a Zombie and a Giant spawner otherwise.

Might, but we'll see what changed in the next snapshot

I leave this info here for now, and might create a separate bug report if this still happens to me in the next snapshot:

Create Ghast Spawner with: /give @p minecraft:mob_spawner 1 0 {BlockEntityTag:{SpawnData:{id:"Ghast"}}}
then after the first Ghast spawned, the inside entity changes to a Pig (16w02a).

Not related to this but, create a seperate issue for that (don't forget to search first)

@unknown what you experience is probably MC-92282

The bug is still there for enderman spwaners

@unknown:

1. I mentioned them in the description and have screenshots
2. It says it's fixed for next version

Still not fixed for all mobs, for example in 16w03a these (and probably more mobs) are still affected:

• Ghast (tentacles)

• Guardian

And like I said this fix will cause problems for giants. And guess what is now the case, Zombies and Giants have (nearly) the same size...

Seriously why did you consider this as bug in first place. I understand that it might make sense for Ghasts and Giants, but now the mob is pretty small and I personally do not like it 😞

@up
In 16w03a these are affected, and also enderman seems to be a bit too small (compare with skeleton or zombie). Also, Ghast's body corners are outside the spawner aside from tentacles.

@unknown Giants are unsupported, but perhaps might be added back in the game later, perhaps a new texture will come with it then as it's not a undead mob then you can tell the diffrence between the 2.

Anyway, it's useless to have a Giant in a spawner now as it won't spawn it anyway, under any condition

@unknown the issue here is that entities render outside of their spawner, due to the way of fixing not all entities are the same scale, the enderman was fixed and now is smaller then the skeleton.
that's the way how @unknown decided to fix it

Ender dragon spawners still have the dragon head and tail jutting out. And the dragon head seems to point into the spawner, and the tail points out.

Very big slimes, still have body jut out.

/setblock ~ ~1 ~ minecraft:mob_spawner 0 replace {SpawnData:{id:Slime,Size:8,PersistenceRequired:1}}

AreaEffectCloud still have it's hitbox out (visible through F3+B).

/setblock ~ ~1 ~ minecraft:mob_spawner 0 replace {SpawnData:{id:AreaEffectCloud,Duration:2147483647,Radius:8f,Particle:"flame"}}

Big jockeys, still have heads, that jut out.

/setblock ~ ~1 ~ minecraft:mob_spawner 0 replace {SpawnData:{id:Skeleton,PersistenceRequired:1}}

This thing still render out.

/setblock ~ ~1 ~ minecraft:mob_spawner 0 replace {SpawnData:{id:ThrownEgg}}

.

@unknown could you attach screenshot? I'm at school right now

Why? It's just,a spawner with technical entities inside! Like AreaEffectCloud with Radius:5f tag, and other entities. And slime which are very big, ender dragon, etc. If you don't want them to spawn, then this command will do.

/gamerule doMobSpawning false

They are now for display.

Because having the images makes it more clear to the developers how bad the issue is, and again, I'm at school now

@unknown I can only confirm for the big slimes, make sure you run the latest snapshot

I'm always, running the latest snapshot. The AreaEffectCloud can only be seen when you press F3+B.

I know, I did that, but still the ender dragon, the eraeffectcloud ans the thrown egg were completely inside the spawner

I mean big AreaEffectCloud entities.

/setblock ~ ~1 ~ minecraft:mob_spawner 0 replace {SpawnData:{id:AreaEffectCloud,Duration:2147483647,Radius:101f,Particle:"flame"}}

This very big AreaEffectCloud is surely jutting out.

Confirmed for EnderCrystal.

/setblock ~ ~1 ~ minecraft:mob_spawner 0 replace {SpawnData:{id:EnderCrystal,Glowing:1}}

.

Confirmed for this.

/setblock ~ ~1 ~ minecraft:mob_spawner 0 replace {SpawnData:{id:MinecartRideable,DisplayTile:sand,CustomDisplayTile:1,DisplayOffset:30}}

Minecart with display tile offset.

Ok, when you make sush entities you are just asking for it, I will test them tomorrow (2:26 here now) and say a way on how to fix it (always render era effect cloud as big as radius 6, don't render the offset on the custom tile in minecarts) and other ones (haven't tested paintings/item frames as they require some tags to now crash your game

Still present in 16w04a

I already added that version...

found a bunch more

Confirmed for 1.9.1-pre3.

Tested mobs: Squid, Guardian, Mooshroom (a tiny bit), Ocelot, Ghast, Slime, Magma Cube, Shulker

Here's a list of entities that are affected by this bug.

✔ = Not affected
⚠️ = Sticks out with certain NBT tags
❌ = Sticks out with no special NBT

This table ignores armor/held items.

If I made a mistake, tell me!

1. There's a dot in the first table, which makes an additional element in the last row.

2. I think "Affected?" should be changed to "Unaffected?", because it's true when not affected and false when affected.

First one was my mobile phone's mistake, second one no need to change that, the icons already have a value determined above the table

Confirmed for 1.9.3-pre3.

Confirmed for 1.9.4.

Marked some things as Minor (:info:) in the table, so they don't get as much attention as the bigger issues.

Confirmed for 16w20a. Affects PolarBear (❌ ) - sticks out the sides

Confirmed for 16w21a.

Confirmed for 16w21b.

Confirmed for 1.10-pre1. (Tried EnderCrystal, DragonFireball, and Ghast.)

Confirmed for 1.10.

Tests in 1.10:
Confirmed for: Arrow, EnderCrystal, Ghast, Guardian, MinecartChest, MinecartCommandBlock, MinecartFurnace, MinecartHopper, MinecartRideable, MinecartSpawner, MinecartTNT, MushroomCow, Ozelot, Painting, PrimedTnt, Shulker, Slime, SpectralArrow, Squid, WitherBoss, PolarBear.
Fixed for: AreaEffectCloud, DragonFireball, Fireball, Silverfish.

Guardian is not minor in my opinion. Slime and LavaSlime are now the same size for every "Size", but stick out a bit at the sides.

Confirmed for 1.10.1.

Still happens for DragonFireball, Fireball, and Silverfish. It's just not very noticeable.

It also happens in 1.10.1 for big paintings. I didn't test all, I'll do that the next time when 1.11 comes out.

The suggestion for the Invul tag of the WitherBoss

might be invalid, but it will grow smaller and flip itself at one point, 5000 makes it be out of the spawner in total, a way to fix is to ignore the Invul tag when rendering the entity inside the spawner

is probably not a great idea. People will then complain that the entity being displayed is not the one that is spawned.

Confirmed for 1.10.2.

Can confirm for MC 1.12.1.

Still in 18w50a.

Confirmed in 1.15.2 and 20w20b.

How do you put a painting in a mob spawner??

By providing SpawnData NBT.

Can confirm this behavior in 21w39a. Please take into consideration that the command usage of spawners has changed in 21w37a. You can use the following command to reproduce this in versions 21w37a and above.

/setblock ~ ~ ~ minecraft:spawner{SpawnData:{entity:{id:"minecraft:ENTITY"}}}

Can confirm in 21w40a.

Can confirm in 1.18.1.

Can confirm in 1.19.

Can confirm in 1.19.1.

Can confirm in 1.19.2.

Iron golems, endermen, wolves and zombified piglins all appear to render completely fine inside spawners so I'm not sure why these are marked as ❓ .

I've also tested goats, wardens and frogs since these aren't listed in the ticket and they seem to render completely within its bounds.

Polar bears, however, are indeed a problem and should be marked as such:
