Hello guys,

well, I have a huge problem I can't answer with searching on forum or with Doc forge. I want to do a custom Inventory player, but for that  I need to create a capability for stock this "inventory". Then I checked the doc here : https://mcforge.readthedocs.io/en/latest/datastorage/capabilities/ but, either I do not understand, or something is missing... (But I think I do not understand, I have a basic English, I find)

 

Then, the best I can do is to show you what I already do, and what I do wrong.

 

CapabilityHandler.class :

public class CapabilityHandler {
    public static final ResourceLocation ITEM_HANDLER_CAPABILITY = new ResourceLocation(AfraidOfTheDark.MODID, "custominv");

    @SubscribeEvent(priority = EventPriority.HIGHEST)
    public void attachCapability(AttachCapabilitiesEvent.Entity event)
    {
        if (!(event.getEntity() instanceof EntityPlayer)) return;

        event.addCapability(ITEM_HANDLER_CAPABILITY, new CustomInventoryProvider());
        //event.addCapability(CustomInventoryCap.ID, new CustomInventoryProvider(new CustomInventory()));
    }

    @SubscribeEvent
    public void itemPickup(EntityItemPickupEvent event) {
        // TEST capability
        if(event.getEntity() instanceof EntityPlayer) {
            System.out.println("inserting " + event.getItem().getEntityItem());
            //event.getEntity().getCapability(CustomInventoryCap.CUSTOM_INVENTORY, null).insertItem(0, event.getItem().getEntityItem(), true); That was a test
            event.getItem().setDead();
        }
    }

}

Error on CommonProxy : line : "CapabilityManager.INSTANCE.register(IItemHandler.class, new IItemHandler(), IItemHandler.class);"

 

Well, I hope there is everything you need for helping me ! I think there is so much things to change, but if I can understand where from the problem, that could be very cool.

Thank you

IItemHandler already has a capability associated with it. You need to use a different interface. The easiest way is to just make an empty marker interface for your item handler.

Should I do a new interface who extends "IItemHandler" then ? Really, I don't see what class does I need, and how tu use it... I tried, but really I'm doing it really bad...

Well, get it, but in my Storage, how should I WriteNBT() and ReadNBT() ?

There is a lot of NBT type, or maybe there is another way ?

 

(Sorry to waste your time, look like understand nothing, but I really don't understand how to use correctly everything of Capabilities, I have created one for money who work very well, but when I want to doing with slot, that like I'm loosing every landmark.)
