MC-65065Content of Minecart with Spawner is not sent to the client
The bug
The mob inside a minecart with spawner is never rendered, even if the spawner is customized.
How to reproduce
- Summon a minecart with spawner that spawns mobs other than pigs
- Notice the lack of a miniature
(A spawner minecart that is not customised will spawn pigs, but requires light and grass to actually spawn them. They too lack a mob inside).
Note
Note that since 15w33a, no miniature is rendered at all; prior to this verison, a pig was rendered. The attached screenshot is from before 15w33a.

Create a spawner for example with:
/setblock ~ ~ ~ mob_spawner 0 replace
and the entity is always a pig. That bug seemed to first appear in some 15w32 snapshot.
Possibly relates to MC-65065 which has this behaviour with Minecart Spawners.
resolving to MC-65065
Resolving this as a dupe of MC-65065, since the underlying issue is the same (the contents of the spawner minecart is not sync'd with the client), even though the resultant behavior is different (I'll put more info in the comments of that ticket). If you want, I can transfer ownership of that ticket for you.

I spawned this minecart with spawner using summon command. It spawns mobs correctly, but mob miniature is incorrect (pig instead of skeleton). Effect of this bug is only visual, it does not affect spawning.
Bug affects all minecarts with spawner in 1.7.2. Tested with 5 types of mobs, always the same result (pig miniature inside the spawner).
I can confirm this for 14w32d, though the pig is also off centered now
Still in pre2
Confirmed for 1.8
Confirmed for
The rotation also doesn't stop if the player gets out of range
In the latest snapshots, not sure which one, the entity seems to have disappeared completely?
Confirmed for 15w47c
Confirmed for
The reason for that is, that the func_151260_c() method in the /Client/src/net/minecraft/entity/EntityTrackerEntry.java class (MCP 1.8 names) sends a S0EPacketSpawnObject packet for minecarts. This packet is only able to store one additional integer for special information. However for minecarts this integer is used to represent the minecart type. This means the client does not get the information about which mob is visible.
One way to "fix" this would be to override the method NBTTagCompound func_174819_aU() in the /Client/src/net/minecraft/entity/ai/EntityMinecartMobSpawner.java class to either return all NBT data or only the entity to spawn. As updating packets are not send every tick, it might be better to send all the data to make sure the displayed mob changes at the right point for the client. This would also require to add code to the func_174834_g(NBTTagCompound p_174834_1_) method in the /Client/src/net/minecraft/entity/Entity.java class to just call the readEntityFromNBT(NBTTagCompound tagCompund) method. Or adding a data watcher for these fields might work as well, but I am not too familiar with how they work.
There is no entity in spawner minecart for 1.9-pre2
Is this still an issue in the latest snapshot 16w44a? If so please update the affected versions.
This is an automated comment on any open or reopened issue with out-of-date affected versions.
Currently this cannot be reproduced due to being blocked by
MC-110426.After some more investigation, I've decided that
MC-110426should be merged into this ticket. The actual difference that caused the mob to stop rendering is mundane: Mojang removed the call to TileEntityMobSpawnerRenderer.renderMob(minecart.func_98039_d(), minecart.posX, minecart.posY, minecart.posZ, partialTicks) in RenderMinecartMobSpawner in 15w33a (for 1.9; it exists in 15w32c). The underlying issue of the mob inside not being sent to the client still exists, and could be fixed nowadays with NBT entity metadata (as is done with parrots on players). Were the rendering to be re-enabled without fixing the syncing, the pig issue would resurface. This ticket already listed versions where the mob didn't render for a few versions, so it is bit more confusing to try to keep them separate.In 1.16.1 and 20w29a
