I am trying to make a command thing that edits NBT on an item and changes how the item functions. This is really hard to explain can someone take a look at this?

Okay, you just vomited a huge chunk of code into gists without even enabling syntax-highlighting.

Please, at the very least, explain what your issue is, except "troubles with many idk things".

Your right and I am sorry.

 

I am trying to use ShoutSetBook code to change the NBT of the ShoutBook  item so that it runs the shout by right-clicking but, I can't seem to get the shout to cast and I don't know what's wrong.

 

I hope that explains that better.

So if the stack has no NBTTag you create a new one and then do nothing with it. You need to assign it to the stack with ItemStack#setTagCompound

Any particular reason you are implementing ICommand directly instead of using CommandBase?

ok

The NBT problem is fixed but I have another.

I am not sure if my if statement that checks if the player is holding the shout book is working, can someone take a look and correct me if I am wrong.

• You cannot do this. Data like that must be stored in the ItemStack (like you already do). You cannot store it in the Item instance in any way.
• You cannot compare strings using ==.
•  Use TextComponentTranslation instead of TextComponentString + I18n. Otherwise you are translating on the server and you will always get English.
•  You cannot compare ItemStacks using ==.

Thanks that helped what is the best way to compare strings and item stacks?

String are Objects, not primitives - even though they are given special handling in java. They override the equals method so string1.equals(string2). ItemStack has a number of methods starting with areItemStacksEqual to compare 2 stacks

Ok, nearly working my last problem is when I right click on the book the shout cast's twice.

Maybe check if world is remote? I've had this problem before with duplicate events.
