You cannot break minecarts with large-sized entities inside of them

The bug

This affects horses, donkeys, mules, magma cubes, slimes, shulkers, and sniffers.

Once horses/slimes/magma cubes/shulkers are in minecarts, it is very difficult to free them, as their hit box is much larger than the minecart. You just end up hitting the horse/slime/magma cube/shulker instead of hitting the minecart.

You can free them by breaking minecart from underneath by making a hole.

How to reproduce

/summon minecart ~ ~ ~ {Passengers:[{id:"horse"}]}
/summon minecart ~ ~ ~ {Passengers:[{id:"shulker"}]}
/summon minecart ~ ~ ~ {Passengers:[{id:"slime",Size:1}]}
/summon minecart ~ ~ ~ {Passengers:[{id:"magma_cube",Size:1}]}
/summon minecart ~ ~ ~ {Passengers:[{id:"sniffer"}]}

This isn't duplicate. This report is about the buggy Horse's hitbox, not the mobs falling into ground.

Anon Ymus

Reopened because of the hitbox bug.

Ezekiel

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.

Fred Nicolson

It has been patched, although horses still fall into the world if you break the mine cart their in.

Anon Ymus

No, it definitely still exists.

Maggie P.

I had the same problem. What I did to fix this is mount the horses like you normally would (you and the horse are in the cart at the same time) look directly at the cart from above, and RIGHT click the mine cart and you will get off the cart with both you and your horse without either having damage.
Hope this helps!

Maggie P.

I meant left click to destroy the cart. Then dismount your horse and if you walk in the cart riding the horse you will be in the mine cart once again.

Fred Nicolson

I did the above slightly differently, while the horse is in the ground, mount it and then jump 🙂

Darren Keen

Sadly i lost a good horse to this bug... i tried to free him by sending the minecart into a lake Should have read this first...sigh..

Is this still a concern in the current Minecraft version 1.7.4 / Launcher version 1.3.8 or later? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.

Fred Nicolson

I can confirm that the bug still exists.

Confirmed for 14w11b, but now activator rails can get off horses automatically.

Like Gary Closse said, now activator rails can help, but still a problem

marcono1234

Confirmed for

  • 1.8.4 however fixing this "bug" is probably nearly impossible because the hitbox of the hourse is simply bigger than the hitbox of the minecart

Fred Nicolson

Not really Marcono1234, it just involves some relatively simple changes to the way Minecarts work.

BlockZooBuilder

You can run them over an activator rail to dump them out of the cart. I'm not sure there's any way to fix this, except by making their hitboxes arbitrarily smaller. 

Avoma

Can confirm in 1.19.

Can confirm in 1.19.2.

This also affects sniffers since they're now able to enter minecarts. I've updated this ticket accordingly.
