[MC-41839] Chicken Jockeys with Baby Zombie Pigmen do not work

you can spawn them just like the normal chicken jockeys by using spawn eggs (1/2000 chance afaik), but the baby zombie pigmen does not control the chicken. The chicken AI still works (seeds ..). If you anger the pigmen it will only be able to attack if you're in close range.

You can try it yourself by using:

'/summon PigZombie ~ ~ ~ {IsBaby:1, Riding:{id:Chicken}}'

Confirmed, but why would you find a Chicken in the nether?

what? chicken - baby zombie pigmen - jockeys just spawn like regular zombie pigmen, just with a (much) lower chance.

A naturally or per egg spawned chicken jockey is different to a "pigzombie riding a chicken" spawned per /summon.

Guybrush Threepwood 2013-12-09T14:19:01Z

no, it's not. it's the exact same nbt data.

Ok, reopened.

Could be this related to why people are randomly finding chickens in the nether? The baby zombie pigmen are despawning and leaving the chickens?

Guybrush Threepwood 2013-12-12T11:29:17Z

yes, exactly.

Note: chicken jockeys only work because the chicken is a special "aggressive chicken". No mobs have riding AI. In any situation where one mob is riding the other the mount (NOT THE RIDER) has control. This is why using command blocks to spawn mobs riding horses doesn't work. The horse acts like a normal horse (wandering around randomly, snorting, occasionally eating grass) leaving the rider unable to attack using a sword because he can't approach you.
So apparently the real bug is that baby zombie pigmen are being spawned on regular chickens instead of the specialized "aggressive chickens".
Note that the leftover chickens are causing catastrophic problems with 1.7.4 (hanging around in dark caves laying eggs for zombies to pick up, thus making them persistent, leading over time to pockets of 300 zombies that are pretty much undefeatable without using cheats and preventing any other hostile mobs from spawning).

there is no special 'aggressive chicken'. there's a special case in the code when a zombie rides a chicken to give control to the zombie. the same should be the case with zombie pigmen, because they also spawn riding chickens. or this is just a mistake, as zombie and zombie pigmen have a similiar spawning class and they only enabled the spawning by accident.

anyway, you hold a true point with the eggs updating the zombies, that can pickup loot, with a persistencerequired tag. especially with the pack spawning algortihm in minecraft, where you can get 1 chicken jockey and some special zombies that can pickup loot.

I dont see the spawned chickens as a problem though, as they only spawn in a really small quantity. but yeah, maybe they should introduce a new tag for chickens like 'canLayEggs' and disable it for the chickens spawned as part of chicken jockeys.

Are they still spawning in the latest snapshot? (14w03b)

Guybrush Threepwood 2014-01-17T13:28:16Z

Yes, they still spawn and they still don't work.

Walter20210 2014-01-24T00:39:47Z

And in the 14w04a too :/

Itouch2 2014-02-18T11:32:16Z

This mob is completely bugged, yet I believe that zombie pigman AI has been improved in latest snapshots.

Itouch2 2014-04-21T08:53:50Z

That was Fixed in 14w11.

Axel Aronsson 2014-08-27T05:16:56Z

I had an encounter with this just yesterday so...

Noproct 2014-09-10T20:24:53Z

That is awkward, this bug is still in 1.8. I have some baby zombie pigmen chicken jockeys on my SSP world that do not attack me. I am not sure. Maybe they loose the AI after some time.
