The bug
Right clicking on a tamed wolf, ocelot or parrot while holding an item makes the wolf, ocelot or parrot sit / stand up and uses the item.
How to reproduce
Tame a wolf, ocelot or parrot
Right click it while holding an item with right click action, for example a fishing rod
→ The pet will sit but you also used the item you are holding
Code analysis
Based on 1.11.2 decompiled using MCP 9.35 rc1
The methods net.minecraft.entity.passive.EntityWolf.processInteract(EntityPlayer, EnumHand)
and net.minecraft.entity.passive.EntityOcelot.processInteract(EntityPlayer, EnumHand)
both don't return true
when the wolf or ocelot sits or stands up.
Important:
To not break the spawn egg and breeding behavior the methods should probably first call
net.minecraft.entity.passive.EntityAnimal.processInteract(EntityPlayer, EnumHand)
.To not break name tag behavior the methods should probably call
net.minecraft.item.Item.itemInteractionForEntity(ItemStack, EntityPlayer, EntityLivingBase, EnumHand)
.
Can confirm.
Still persists in 1.10
