How do you put an enchanted item or an enchanted potion in an item frame with a command block?

Question

I'm making a map for fighting and I made classes to choose from. I condensed it so all you have to do is press a button to scroll through the classes. Once the button is pressed all the command blocks are cloned and replaced to change the specific items in each class. Above the 4 buttons are picture frames with a simple item that compares to the class, like a bow for an archer, sword for warrior and so on. I tried to put a potion in the frame but only got a bottle of water. I tried /summon but the frame and items would pop out when replaced. Lastly, I found this but I don't know where to put the ench tag or how to format it, also don't know how to do the xyz, when I did, it changed every single frame in my world, terrible :(

So my questions are: How do you put enchanted items/potions in an item frame, to a certain coordinate with command block and have them replace?

I'm guessing it should look something like this, and I have no idea where the xyz coordinates go.

/entitydata @e[type=ItemFrame] {Item:{id:minecraft:'item'}}

/entitydata @e[type=ItemFrame] {ench:[{id:minecraft:'enchanted item/potion'}]}

Answer 1

The coordinates can be added as target selector arguments, i.e. inside the @e[...], using the x, y, and z arguments, combined with r to set a maximum radius. Note that Tilde notation is not allowed for this, you need the absolute coordinates.

Placing an enchanted item in an Item Frame has to be done all at once, since the entitydata is running on the Item Frame, not on the item that is in it. This is done by setting the Item tag of the item frame to a valid compound NBT structure for an item, such as

{id:"minecraft:stone_sword",tag:{ench:[{id:16,lvl:1}]}}

for a Sharpness I Stone Sword.

Overall, the command you want to be running might look like:

entitydata @e[type=ItemFrame,x=1,y=2,z=3,r=2] {Item:{id:"minecraft:stone_sword",tag:{ench:[{id:16,lvl:1}]}}}

Be careful regarding the closing parentheses.

Answer 2

I made a picture of NBT data tree for the frame picture. As stated above, you need to change the data of item frame, not the item inside it.

If you wonder what I used for showing this - it is Forge mod for editing NBT data ingame. I think it is superior tool for mapmaking :) You can get it HERE , however you need to have Forge installed. (but in theory, you can edit all you need and then run it with normal vanilla client -> NEEDS verification , however something says me that forge saves are not quite backward compatible with vanilla)

But as always, you can use Commandblock.

Answer 3

Try Item:{id:"minecraft:potion",tag:{ench:[{id:16,lvl:1}]}}, replacing the enchantment data with whatever you want. For more information, including potions, check this page on Minecraft Wiki.

Regular Item:

/entitydata @e[type=ItemFrame,x=1,y=2,z=3,r=1] {Item:{id:"minecraft:iron_chestplate"}}

Enchanted Item:

/entitydata @e[type=ItemFrame,x=1,y=2,z=3,r=1] {Item:{id:"minecraft:bow",tag:{ench:[{id:34,lvl:3}]}}}

Regular Potion:

/entitydata @e[type=ItemFrame,x=1,y=2,z=3,r=1] {Item:{id:potion,Count:1,Damage:8193}}

Splash Potion:

/entitydata @e[type=ItemFrame,x=1,y=2,z=3,r=1] {Item:{id:potion,Damage:16428,tag:{CustomPotionEffects:{Item:[{id:7,Amplifier:2,D‌​uration:1000}]}}}}

Remove Item Data:

/entitydata @e[type=ItemFrame,x=1,y=2,z=3,r=1] {Item:{id:"minecraft:air"}}
