Custom defence for armour not working

[Ginj]

Spawning in vanilla items with a customised 'armor' attribute through commands does not work. I noticed this problem in a 1.9 version and have tested it in other versions, including the latest and recommended 1.10 versions. I have tested this without any mods except Forge itself installed, and it seems to be a problem stemming from Forge.

 

Here is a screenshot of the problem: http://i.imgur.com/p4ZJ0ZX.png

As you can see, this iron chest plate claims it only provides the +1 defence it was spawned in with, but when worn it actually provides the full 6 defence of a vanilla chestplate. I also tried making an iron chestplate that would provide +1 defence simply if held in the off hand, and while it still claimed to give +1 defence holding it gave no defence increase at all.

 

This is not a purely visual issue, either. The custom items don't provide any modified defence in action. A +1 iron chestplate defends just as much as a vanilla +6 chestplate. I even ramped things up to the extreme just to make sure, by wearing a vanilla diamond chestplate and then getting hit by an iron golem, and then again wearing a custom +300 defence diamond chesplate, and there was no difference in defence.

Log file is useless because your issue is not a crash.

Post code.

I believe this was moved from 'support & bug reports' inappropriately. I am not talking about custom armour I have modded into the game. I am talking about armour with custom defences made with a /give command. I had hoped that me talking about the armor attribute and showing screenshots would have made that obvious enough.

Ah.

In which case, yes, it seems like this was moved inappropriately.

As for what you've done: I have no idea. Seems to me like that might be a vanilla bug.

There we go. Sorry, I should have been a bit more explicit about this being with attributes/NBT editing and commands.

 

Seems to me like that might be a vanilla bug.

 

Definitely Forge. I've tried this in vanilla and there's no problem.
