[1.12] Add custom nbt tags to vanilla mobs.

[_Bedrockbreaker_]

I have an item named cat hair that is supposed to drop from shearing cats. The subscibe event recognizes correctly when I have right clicked an ocelot with shears, but I want a timer on each sheared cat (like the sheep) in order for the player to be able to shear the cat again. How would I be able to add an nbt tag to each cat to do this? Also, as side questions, how could I figure out if the cat was tamed, make the cat not sit/stand when clicked, and change the model to a hairless cat when sheared.

Use a Entity Capability see here

EntityOcelot.isTamed()

Just cancel the event.

Subscribe to the RenderLivingEvent(s) cancel the Pre event and Render your new Model in the Post event. At least I believe that is the way to do it.

Sorry for small bump, but I can't for the life of me figure out how to use capabilities. I have looked through the documentation several times and searched up others' tutorials and I am at a loss.. any help? 

Relevant capability files:

You still need to attach the capability to the entity

[Choonster]

You need to call CapabilityManager#register in a method called in preInit, you can't call it in a field initialiser because it returns void.

 

The Class object you pass as the first argument of CapabilityManager#register (IShave.class) is the same Class object you need to pass to the @CapabilityInject annotation to inject the Capability instance into a field.

 

You need to attach a provider for your capability to the entity using AttachCapabilitiesEvent<Entity>.

 

I have several examples of capabilities in my mod. You can see the APIs here and the implementations here.

Okay, from you say, It seems the capability seems to look fine (really, you didn't say anything about the capability itself, besides implementing it, so I assume nothing wrong there.) It looks like I did forget to put the CapabilityManager in a method, but it still gives me an error of register cannot be resolved or is not a field. I looked through the examples you provided Choonster, and tried to look at what you are doing, but it doesn't seem you have anything for the "factory" part of register and I don't quite know what to put there.
