[1.12.2] Multiple Capabilities

[NolValue]

So, I've been looking around at various old forum posts and such after being unable to figure this out myself, aside from some github sources which implement their own capability system instead of using forge's which is way too much effort for me to do.

I'm going to go ahead and ask this:

What's the easiest way to implement a multiple capability system, IE Stats (Strength, Constitution, Dexterity, etc. . .) with each stat containing a value.

 

Also, how would one inject it? The new capability system is way messier than IEEP for me to figure out.

 

Other things I need to be able to do is read, set, and add to the stats.
That's really it. 

I've been trying for the past 3 days to get a working code and was unable to. I don't need you to code the full thing out, just some pointers for what I need to do, seeing as the Forge Documentation is very limited in what it tells you.

Are you sure you need multiple capabilities? why not just one capability with all those values in it?

 

What are you using your capability on?

If your using Items/ItemStacks have a look at this code in my mod where I implement both the Energy Capability and my own Weapon Modules capability on my Item/ItemStack

ItemGun

This code is probably very messy and bad, but it was based on code written by one of Actually Additions authors, so I doubt its that horrible.

Well, I am attempting to use it on players, however I can still probably use your code to figure out how to do it for a player.

Also I do want 1 capability with multiple values, sorry for wording it so poorly.

This might be a good post to take a look at, and its relatively recent.

I actually have been through that post, several times actually. It uses an outdated method for Capabilities which is completely deprecated, otherwise, I would be using that.

Well, it seems that the new system is far too big of a mess for me to even to begin to attempt to use, so I'm just gonna go ahead and drop modding once again.

 

So thread closed I guess or whatever.

They are hard, but once your heads round them they Just Work (aside from syncing)

What method is "completely deprecated"???

Here, take a look at these three classes:

The interface is here:

Capabilties are not a "mess" at all. They work quite well. They aren't really that complicated either. You just attach the capability to anything which is a capability provider and define the types of field you want it to contain.

 

Regarding any deprecated methods you might encounter. Deprecated methods can firstly usually still be used, they are just not the best way. Secondly they are often commented with a note that tells you what the replacement method is. Lastly, you can use your IDE to look at he type hiearchy (or "structure") of the class to see a list of available methods and it is usually quite obvious what the new one might be -- often they are named the same but just have a different parameter list prototype.

Well, for someone like me who hasn't touched modding since all the way back in 1.7.10, it's been a huge pain in the butt to learn the capability system. 

 

You telling me the old method is still usable is nice, as I had no idea what the hell a factory was, haha.

Anyways, I'm assuming what I need to do is to have an ENUM with the stats I need, then use an NBT compound to put the ENUM and the Stat's value into the Player, correct?

It doesn’t have to be an enum, it can be almost anything, however the most common things that are used are booleans, enum and integers. Remember you are going to have to be syncing your capability a lot, so yes enums are probably the best choice

A factory is a class that creates instances of another class.

(What is a hammer factory? Why, its a building that builds hammers...)

I found capabilities very confusing at first, too. The Forge documentation didn't help me at all until I was already thoroughly familiar with capabilities. Try this tutorial.

It will get you started with a single stat called Mana, but you can obviously extend that to anything you want.
