Minecraft – Prevent Players From Stealing From Item Frames

The syntax for clear is as following:

/clear [player] [item] [data] [maxCount] [dataTag]

Your command is as following:

/clear @a torch 1 1 {display:{Name:"Special Torch"}}

You are trying to clear (for everyone in the server) torches with a data value of 1, a max count of 1 and a name of "Special Torch".

Seeing as there are no torches with a data value of 1, try using the following:

/clear @a torch 0 1 {display:{Name:"Special Torch"}}

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.
