[1.10.2] Save NBT on a file in the world(Changed Subject Later)


Recommended Posts

Posted

Since I decided that capabilities are waay too complicated for me to handle,

I'm now looking for a way to just save an NBT compound onto a file in the

world folder(WORLD! NOT DIMENSION!)

And read it later.

This ofc will only be done on server side(And I'll mess later with packets)

If you want stuff attached to the world, use WorldSavedData. If you want stuff attached to players or entities, do not do this yourself! Capabilities are the way to go.

 

I really cant understand it!

Please just give me a video that explains it really!

 

Capabilities seem so complicated for me!

First off, Thank you so very much for taking your time to explain this! It means alot to me that there is someone that is willing to help..

 

Now, I've read what you said about 4 times, Repeating sections again and again..

But I still struggle to understand..

 

Do I need to make a custom CapabilityProvider? How?

Do I need to attach the Capability some how to the CapabilityProvider? How?

Can you explain what you mean by "implementation of an interface"? I probably know this but dont know how its called...

Do you know of any open source mods that do this? Let's say, Add an Capability to the Player/manipulating it/checking for it's values?

 

I belive this is a "valid" capability?

public interface ICResearch{
    boolean getMainResearch();
}

Implementation is similar to extending class, you just are not limited by how many you can implement and instead of saying extends it is implements and you can only implement and interface. Tinkers Construct I believe is Open Source and should have some sort of capability. Also interfaces can extend interfaces. Read the stuff in parentheses as that is where diesieben denotes more information and names of interfaces and classes.

I think it needs to extend a Capability object/interface of some sort, but that would be a valid interface for the custom one, yes.

 

You'd then need to implement it.

 

I'm away from dev, so I can't check.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

 

DO NOT PM ME WITH PROBLEMS. No help will be given.

Do I need ICResearch to extend a custom provider?

If so, what's a valid capability provider?

Capabilities are simple.

 

There are capability providers (interface

ICapabilityProvider

). By default these are

Entity

,

TileEntity

,

ItemStack

and

World

. These now have two very simple methods:

hasCapability

and

getCapability

. hasCapability checks if the provider has the given capability ("do you have an inventory on the west side?").

getCapability

obtains the

capability

instance ("give me your inventory on the west side").

 

A capability itself is now represented by an interface (for inventories it's

IItemHandler

as an example) and a

Capability

object. The Capability object is just the identifier for the capability (for

IItemHandler

it's stored in

ItemHandlerCapability.CAPABILITY_ITEM_HANDLER

). You pass this object into

hasCapability

/

getCapability

to interact with the capability provider (see above). In this example getCapability would then give you back an

IItemHandler

.

 

So far this is just for things providing their own capabilities. But you want to attach a capability to something that is "not yours" (the player entity). For that you can use the

AttachCapabilitiesEvent

, which allows you to provide your own capability provider instance (i.e. something that provides capabilities via

hasCapability

and

getCapability

). Forge will then multiplex ("combine") the original provider (in this case the player entity, remember all entities implement

ICapabilityProvider

) with your attached one (and any others attached by other mods).

 

How to make your own capability? Well, first you need an interface that represents it and an implementation for that interface (an interface on it's own is pretty useless without implementation, right?). Then you need to register it using

CapabilityManager.register

and request the capability instance using

@CapabilityInject

. You now implement ICapabilityProvider and you can expose your capability.

 

Last step, how to make your capability save to disk? If you are one of the "normal" capability providers this is easy (entities, tile entities, etc. all have mechanics to save to disk, they can just pass these on to their capabilities). If you are in an attached provider however you need to additionally implement

INBTSerializable

on your capability provider. If you do that, forge will call the methods defined in that interface on your provider and let you save to disk that way.

But I'm stupid....

I need to see a code's prespective of using the providers to capabilities

 

Sadly I also need to leave the DEV pc for an hour or 2....

I'll try to awnser stuff from my phone I guess...

Do you know of any open source mods that do this? Let's say, Add an Capability to the Player/manipulating it/checking for it's values?

 

I have an example in my mod:  API, implementation

 

This is a bit complex because the

IMaxHealth

object stores the entity's bonus max health and manages an

AttributeModifier

that actually applies the bonus max health to the entity.

Please don't PM me to ask for help. Asking your question in a public thread preserves it for people who are having the same problem in the future.

I attempted again and again for the past days and couldnt figure it still..

I think ill just go with my previous plan which is using the achievement system to

Do this...

 

 

I dont know why capabilities are do hard to use really, usally i learn these things really quickly..

    • So me and a couple of friends are playing with a shitpost mod pack and one of the mods in the pack is corail tombstone and for some reason there is a problem with it, where on death to fire the player will get kicked out of the server and the tombstone will not spawn basically deleting an entire inventory, it doesn't matter what type of fire it is, whether it's from vanilla fire/lava, or from modded fire like ice&fire/lycanites and it's common enough to where everyone on the server has experienced at least once or twice and it doesn't give any crash log. a solution to this would be much appreciated thank you!
    • It is 1.12.2 - I have no idea if there is a 1.12 pack
    • Okay, but does the modpack works with 1.12 or just with 1.12.2, because I need the Forge client specifically for Minecraft 1.12, not 1.12.2
    • Version 1.19 - Forge 41.0.63 I want to create a wolf entity that I can ride, so far it seems to be working, but the problem is that when I get on the wolf, I can’t control it. I then discovered that the issue is that the server doesn’t detect that I’m riding the wolf, so I’m struggling with synchronization. However, it seems to not be working properly. As I understand it, the server receives the packet but doesn’t register it correctly. I’m a bit new to Java, and I’ll try to provide all the relevant code and prints *The comments and prints are translated by chatgpt since they were originally in Spanish* Thank you very much in advance No player is mounted, or the passenger is not a player.
