I want to place a wandering trader in a very specific place in a very specific pose in Minecraft, preferably still with an item in hand.
Surely there's a command for right?
No do not go.
You can't put him in a particular pose.
This is not possible with any entity except an ArmorStand.
Spawning a trader with an item should go with
/ summon wandering_trader ~ ~ ~
/ replaceitem entity @e [type = wandering_trader, distance = .3] weapon.mainhand dasItem
With the following command you can spawn a traveling merchant at a specific location.
/ summon wandering_trader x y z
However, you can only spawn him so that he looks in a certain direction (not in a certain pose).
This can be done with the following command:
/ summon wandering_trader x y z {NoAI: 1b, rotation: [90F, 0F]}
There's a https://mcstacker.net/ on which you can fill in fields and then such a command will be generated for you.
It's best to add NoAI so that it doesn't run away. I ran out of time to answer.
Worked 👍
That worked great too.
I'm pleased with that, here you go.
