Provider ICapabilitySerializable

Recommended Posts

public class ArmorProvider implements ICapabilitySerializable<NBTBase> {

     @CapabilityInject(IArmor.class)

     public static final Capability<IArmor> Armor = null;

    
     private IArmor instance = Armor.getDefaultInstance();

    
     @Override
     public boolean hasCapability(Capability<?> capability, EnumFacing facing)
     {

         return capability == Armor;

     }

    
     @Override
     public <T> T getCapability(Capability<T> capability, EnumFacing facing)
     {

         return capability == Armor ? Armor.<T> cast(this.instance) : null;
     }

    
     @Override
     public NBTBase serializeNBT()
     {

         return Armor.getStorage().writeNBT(Armor, this.instance, null);

     }

    
     @Override
     public void deserializeNBT(NBTBase nbt)
     {

         Armor.getStorage().readNBT(Armor, this.instance, null, nbt);

     }
}


It breaks at:

 private IArmor instance = Armor.getDefaultInstance();


Because ... well it's null.

But here:

https://www.planetminecraft.com/blog/forge-tutorial-capability-system/
 

And in other places it says this is how it supposed to be.


http://mcforge.readthedocs.io/en/latest/datastorage/capabilities/#the-capability-system
 

This doesn't offer any documentation if you make a custom one. It doesn't even say you need to subscribe an event to be able to do it...

There is any good examples like really good working example or documentation on Capabilities?

public class CommonProxy implements IProxy {
    
    public void preInit() {
        
    }

    public void init() {
        
    }

    public void postInit() {
        CapabilityManager.INSTANCE.register(Armor.class, new ArmorStorage(), Armor.class);
        MinecraftForge.EVENT_BUS.register(new EventEquipmentSets());
        MinecraftForge.EVENT_BUS.register(new ArmorHandler());
        
    }



And the null is the Armor, because of
 

public static final Capability<IArmor> Armor = null;

And another thing:
 

     public void attachCapability(AttachCapabilitiesEvent<Entity> event) {
        if (canHaveAttributes(event.getObject()))
        {
            EntityLivingBase ent = (EntityLivingBase)event.getObject();
    
            if (ent instanceof EntityPlayerMP)
                event.addCapability(Armor, new ArmorProvider());
        }
     }


There is any way better to put capabilities just on players? Because now it goes through all entities... and it takes a while.

From an instant spawning it now looks like this:
[19:57:06] [Server thread/INFO]: Preparing spawn area: 0%
[19:57:07] [Server thread/INFO]: Preparing spawn area: 1%
[19:57:08] [Server thread/INFO]: Preparing spawn area: 3%
[19:57:09] [Server thread/INFO]: Preparing spawn area: 5%
[19:57:10] [Server thread/INFO]: Preparing spawn area: 7%

For 2 minutes.

The idea was that i wanted some custom data for players... It works as intended once it loads. But it takes way too much.

     public static boolean canHaveAttributes(Entity entity)
     {
         if (entity instanceof EntityLivingBase)
             return true;
         return false;
     }

Yes if i comment the MinecraftForge.EVENT_BUS.register(new ArmorHandler()); it goes quick.

A "common proxy" does not make sense. @SidedProxy is by definition for side-specific operations, the opposite of "common". Common initialization code happens in your main mod class. There is no "common proxy", there should be an interface Proxy and two implementations: ClientProxy and ServerProxy.

The problem started with cpw actually recommending this ("common" proxy) in the comments for the @SidedProxy annotation. Here's what it actually says:

/**
 * Sided proxies are loaded based on the specific environment they find themselves loaded into.
 * They are used to ensure that client-specific code (such as GUIs) is only loaded into the game
 * on the client side.
 * It is applied to static fields of a class, anywhere in your mod code. FML will scan
 * and load any classes with this annotation at mod construction time.
 *
 * <p>
 * This example will load a CommonProxy on the server side, and a ClientProxy on the client side.
 *
 * <pre>{@code
 *  public class MySidedProxyHolder {
 *      {@literal @}SidedProxy(modId="MyModId",clientSide="mymod.ClientProxy", serverSide="mymod.CommonProxy")
 *      public static CommonProxy proxy;
 *  }
 *
 *  public class CommonProxy {
 *      // Common or server stuff here that needs to be overridden on the client
 *  }
 *
 *  public class ClientProxy extends CommonProxy {
 *      // Override common stuff with client specific stuff here
 *  }
 * }
 * </pre>
 * @author cpw
 *
 */

 

I know it "hurts" the brains for those people who have strict semantic thinking (and most coders should be strictly semantic), but it does work and lots of people used it that way for years.

 

But yeah it felt good to finally convert my mods over to a more semantically correct implementation.

    • Okay, so I actually downgraded the mod to 1.20.6 because I did not want to have to deal with vanilla datacomponents. I followed a youtube tutorial and now have a capability I made attach to my modded item. However I am now unsure how to actually retrieve and manipulate the capability of an itemstack. I saw a getCapability function in some tutorials but that seems to have been deprecated...

    • Hallo all! I'm working on a custom mod pack for a few friends an I. However, whenever I launch it, it crashes and returns this error code. It appears to be crashing while trying to render some sprites from different mods, but I can't find a way to fix this.      The game crashed whilst stitching Error:      net.minecraft.client.renderer.texture.StitcherException:      Unable to fit: minecolonies:entity/citizen/nether/noblemale3_b - size: 128x64 -      Maybe try a lower resolution resourcepack? Here's the pastebin of the crash report: https://pastebin.com/17hgAPFS

    • Hi fellow minecrafter,   We've got exciting news from the Pacific Laboratory for Artificial Intelligence (PLAI) at UBC! We're merging the worlds of Minecraft and AI research, and you're invited to join through our platform, plaicraft.ai, to aid our data collection process. It's not just playing games; it's contributing to cutting-edge AI research.   BetterStructures and more!!: We want to make the server as fun as possible for everyone so we recently added a bunch of structural plugins that adds over a hundred of new structures and sites for you to explore and challenge. We are also working on PVP, bedwars and skyblock content, which will make the server even more fun!   Here’s how you can get involved! -Register on plaicraft.ai with your email(you can fake one, as long as you can receive email from it it's fine). -Complete a consent form. -Play Minecraft and contribute to science! (all you need is a Chrome browser and a steady internet, you'll be playing on VM)   Why You Should Participate? -Support AI Research: Your gameplay directly contributes to important AI advancements.  -Free Minecraft Access: Enjoy the game without any cost. -We have shaders and a bunch of cool mods loaded on our instances  -Great Community: Our server currently has a fantastic community, with many awesome players you can meet.   Elephant in the room: Now I want to address some obvious concerns, I sure did a good job making us sound like a scam by the above content. I know that the "free Minecraft" thing has always been taboo in the Minecraft community. So how can I prove to you that this is not a scam? - The easiest way and most official way is that we are approved by the University of British Columbia ethics board, our BREB number is H23-02389. You can verify this case number yourself. - The harder way is that I'll explain the technical details of this project and why we choose to provide free Minecraft. So the goal of this project is very similar to the paper MineDojo or MineRL, we want to collect a multi-modal dataset that consists of video, audio, keyboard and mouse movement. Minecraft has been a very important simulation environment for the ML community and there are tons of papers related to it. Now we obviously don't have enough money like those big tech companies who can just pay people to play, so we have to turn to the Minecraft community. To record all the data mentioned, there needs to be a lot of setup and coding, and it's definitely impossible for us to ask people to run these recording programs on their personal computers. So we carefully configured the AWS EC2 instance to run Minecraft alongside the programs. And that's where and why we also provide you with free Minecraft licenses, of course, we are not giving the account to you, just allowing you to be able to play Minecraft on these instances. You might ask, "Why can't I log in with my account on the instances?", that's because first login with your personal Minecraft account is another privacy risk; second not all our target audiences have an account; and lastly we restricted a lot on what you can do on the instance, basically all you can do is play Minecraft and that's all the data we want, allowing you to log in will make things complicated to control.   For more information on the project and the team, visit Dr. Frank Wood’s website or follow @frankdonaldwood on Twitter. You can also learn more about PLAI lab research on our website (just search ubc plai). Join us in transforming your gaming experience into a meaningful contribution to AI research. Let’s push the boundaries of what gaming can achieve together! Happy plaiing!   Best,  The PLAI Team
