I'm trying to make an item that has a cool down that is itemstack based, not player based, so that it can be dual-wielded without creating a duplicate item that just creates clutter.  I created a capability, and it works, but the issue is trying to apply the cool down, or using any method from the CooldownTracker class. Basically crashes the game. Any idea on what the issue could be or just something that achieves something similar that I can reference would be much appreciated

 

Code (Both Pastebin and Hastebin aren't working rn for some reason):

Please show it. The item class you posted does not use capabilities.

Here's the capability: 

Spoiler

public interface ICoolDown
{
    void canCoolDown(boolean canCoolDownIn);

    boolean getCanCoolDown();

    void setTracker(CooldownTracker tracker);

    CooldownTracker getTracker();
}

That is an interface which your item implements. That is not what a capability is.

Refer to the docs: https://mcforge.readthedocs.io/en/latest/datastorage/capabilities/

Oh shoot sorry! Didn't realize I sent that one by accident, was in a bit of a rush earlier. Here's the capability class

Spoiler

public class CoolDownCapability
{
    @CapabilityInject(ICoolDown.class)
    public static Capability<ICoolDown> COOLDOWN_CAPABILITY = null;

    public static void register()
    {
        CapabilityManager.INSTANCE.register(ICoolDown.class, new Storage(), DefaultCoolDownCapability::new);
    }

    public static class Storage implements Capability.IStorage<ICoolDown>
    {
        @Nullable
        @Override
        public INBT writeNBT(Capability<ICoolDown> capability, ICoolDown instance, Direction side) {
            CompoundNBT tag = new CompoundNBT();
            tag.putBoolean("canCoolDown", instance.getCanCoolDown());
            return tag;
        }

        @Override
        public void readNBT(Capability<ICoolDown> capability, ICoolDown instance, Direction side, INBT nbt) {
            boolean canCoolDown = ((CompoundNBT)nbt).getBoolean("coolDown");
            instance.canCoolDown(canCoolDown);
        }
    }
}

And where do you add it to your item? And where do you use it? Why does your Item implement ICoolDown?

I add it here, and originally used it here too. Thinking about it, yeah it really doesn't make sense for me to implement it into my item

Spoiler

@Mod.EventBusSubscriber(modid = ProjectDawn.MOD_ID, bus = Mod.EventBusSubscriber.Bus.FORGE)
public class CoolDownHandler
{
    public CoolDownHandler() {  }

    @SubscribeEvent
    public static void onAttachCapabilities(AttachCapabilitiesEvent<ItemStack> event) {
        if (event.getObject().getItem() instanceof BoltcasterItem)
        {
                CoolDownProvider provider = new CoolDownProvider();
                event.addCapability(new ResourceLocation(ProjectDawn.MOD_ID, "cooldown"), provider);
                event.addListener(provider::invalidate);
    }

    }

}

 

I'm gonna make it be used there, like I originally had it, instead of in the class. I guess cause I was looking around other classes and thought something in the line of IVanishable it needed to be implemented in my item class

There is no reason to use the event for your own items. Simply override initCapabilities.

Okay, so I override that and just attach the capability through there in the item class?

 

[Edit]

I got it to work by doing that, so how do I fix the cooldown issue exactly?

What is the issue now?

Getting the cooldown to work basically. I got it so it doesn't crash the game whenever I right click, which is a step in the right direction, but still doesn't do the item cool down

Post your updated code.

Here's the boltcaster class: https://pastebin.com/yKTnnjif

And Here's the default capability: https://pastebin.com/w3yRJDGP

I referenced how the PlayerEntity creates it's cool down tracker, and that seems to have fixed the crashing issue I had yesterday, but other than that I really can't put a finger on why it just simply doesn't work. I looked around more in the PlayerEntity class and what uses that method to see if it has something that I don't, but I haven't found anything that could resolve it

Why?

Where do you call CooldownTracker#tick?

I referenced the bucket item class just to get it to work, it was the only class to override that method, I'll change that. Also, I don't have CooldownTracker#tick called anywhere, I didn't know I needed to call that
