    /summon horse ~ ~1 ~ {Passengers:[{id:creeper}],Tame:1}

Code analysis

The following is based on decompiled version of Minecraft 1.9 using MCP 9.24 beta. All method and class names are the names used in the decompiled version.

The methods net.minecraft.entity.passive.EntityHorse.attackEntityFrom(DamageSource, float) and net.minecraft.entity.item.EntityBoat.attackEntityFrom(DamageSource, float) prevent the riding entity from damaging it. This was maybe added for players riding a horse or a boat, strangerwise this is not the case for minecarts and it looks like even if this test is removed the player is still unable to damage the horse respectively boat.

I think it is more correct to say "Creepers can not cannot blow up the boat they ride"

  • 16w04a This is however not a general problem with Creepers and boats. Creepers outside a boat can still blow it up

Thanks for your suggestion. đŸ™‚
The issue title has been changed.

Thank you đŸ™‚
I just noticed it is rather "cannot" than "can not" see ‘Cannot’ or ‘can not’?
