So I need help. So I need a armor stand to summon with a written book. I use this command to summon him.
EDIT: The written book should have text in it. So I need him to hold a custom made book. :D
/summon armor_stand X Y Z {Invisible:1b,Invulnerable:1b,NoBasePlate:1b,NoGravity:1b,ShowArms:1b,Rotation:[87f],ArmorItems:[{},{},{},{}],HandItems:[{id:"ITEM",Count:1b},{}],Pose:{RightArm:[180f,0f,90f]}} 6 1 Answer
You need to specify the item in your command which is written_book. You also need to specify the dataTag value of the item which includes the tags that make up the book. Here is the wiki on the data values of written books. In your case, probably just title, author, and pages.
Here is your armor stand holding a sample book:
/summon armor_stand <x> <y> <z> {Invisible:1b,Invulnerable:1b,NoBasePlate:1b,NoGravity:1b,ShowArms:1b,Rotation:[87f],ArmorItems:[{},{},{},{}],HandItems:[{id:"minecraft:written_book",Count:1b,tag:{pages:["{\"text\":\"Sample book page 1\"}","{\"text\":\"Sample book page 2\"}"],title:"Sample Book",author:IronAnvil}},{}],Pose:{RightArm:[180f,0f,90f]}} 2
