Hey, everyone, I have a problem. I'm still new at working with Armor Stands and some of the more complex commands so bear with me.

So I created an Armor Stand and modified it by using this command:

/entitydata @e[type=ArmorStand,r=3] {CustomNameVisible:1,CustomName:Emmy,ShowArms:1,Equipment:[{},{id:leather_boots,tag:{display:{color:13665433}}},{id:leather_leggings,tag:{display:{color:13665433}}},{id:leather_chestplate,tag:{display:{color:13665433}}},{id:skull,Damage:3,tag:{SkullOwner:"MHF_Alex"}}]}

Everything shows up perfectly fine. The armor is all there. The head is there. The name is visible. Every element of the command works.

Then, in a separate command block, I typed in the following testfor command:

/testfor @e[type=ArmorStand,r=3] {CustomNameVisible:1,CustomName:Emmy,ShowArms:1,Equipment:[{},{id:leather_boots,tag:{display:{color:13665433}}},{id:leather_leggings,tag:{display:{color:13665433}}},{id:leather_chestplate,tag:{display:{color:13665433}}},{id:skull,Damage:3,tag:{SkullOwner:"MHF_Alex"}}]}

So, all I did was swap /entitydata for /testfor. What I got after triggering the testfor command was an error message saying that Emmy did not match the required data structure. What am I doing wrong?

I'm not the most experienced with armor stands either but at a glance I think the issue is indeed with the data structure. It seems like you're passing a bunch of paramters to /testfor that it's not equipped to handle. Start small and then get more specific, see which parameters it's able to receive.

I tried modifying the amount of stuff in there.

I think it's the format. The format that works for entitydata doesn't work for testfor. But now I don't know what DOES work for the testfor commands.


EDIT: Okay, so I found out why one part of the testfor command doesn't work.

If I perform an entitydata command, I can use this:

tag:{SkullOwner:"MHF_Alex"}

If I perform a testfor command, I CAN'T use the above and must use this instead:

tag:{SkullOwner:{Name:"MHF_Alex"}}

Why? Don't know. But I suspect it's because "lol meincraft."


EDIT 2: Looks like removing this part also helped:

CustomNameVisible:1,CustomName:Emmy,ShowArms:1

Testfor just doesn't pick up on that stuff, I guess? Or maybe I did it wrong. But the command works without them.

So ultimately, this command worked:

/testfor @e[type=ArmorStand,r=3] {Equipment:[{},{id:minecraft:leather_boots,tag:{display:{color:13665433}}},{id:minecraft:leather_leggings,tag:{display:{color:13665433}}},{id:minecraft:leather_chestplate,tag:{display:{color:13665433}}},{id:minecraft:skull,Count:1b,Damage:3s,tag:{SkullOwner:{Name:"MHF_Alex"}}}]}

Problem solved, more or less!

You need to make sure that tag types match correctly. CustomNameVisible and ShowArms must be 1b or true. When you just enter 1 in the entitydata command, it automatically converts them to the right value for you. In the testfor command, it will always test for an exact match, without converting anything, so you must enter exactly the right data yourself.
