Problem description

Steps to Reproduce:

1. Modify Plate Chestplate with Unarmed Attack
2. Hold Shears in main hand
3. Empty offhand
4. Shear Sheep

I would expect to ONLY shear the sheep, but I shear the sheep AND hit the sheep with my offhand.

Suggested solution

Do not perform an offhand attack when using shears

Alternatives considered

None

Additional context

If I hold the shears in my offhand to shear, I don't hit the sheep.

You are likely seeing normal vanilla behavior where holding right click after using your mainhand uses your offhand. I suspect you will notice the same behavior if you put a dagger in your offhand, or similar if you put food in your offhand. Please test these to verify if that is your issue. I doubt this is anything that can be fixed, its simply how the offhand works.

You can install Sticky Hands, a mod that prevents automatically using the offhand after the main hand when holding right click too long. Note its not extensively tested with Tinkers.

Did some testing and confirmed this to be a forge bug. When shearing sheep, forge returns that nothing happened client side, meaning the offhand runs client side. Can confirm the interaction with a name tag.

MinecraftForge/MinecraftForge#8597

Forge PR is merged and Tinkers is released for 1.18.2, so closing as fixed.

For 1.18.1 and earlier, no fix is coming unless someone wants to backport the forge PR.
