[1.16.5] Refreshing capability between server and client

[ImNotJahan]

In 1.12.2 I was able to use messages between the client and server (https://github.com/ImNotJahan/danmachi-mod/tree/master/v1.12.2/src/main/java/imnotjahan/mod/danmachi/network) I can't figure out how to get any of that to work for 1.16.5 though. This is all my capability code

Thanks, I'll look at the docs and see if I can get it working

This is invalid.

1. instance is not a LazyOptional, this cast will always fail.

Expand  

Bit off-course from the original question, but I've changed my getCapability code to this

@Override
public <T> LazyOptional<T> getCapability(Capability<T> capability, Direction side)
{
	return capability == STATUS_CAP ? lazyStatus.cast() : LazyOptional.empty();
}

based off of what I found in the forge docs on capabilities, but capability is now never equaling STATUS_CAP, so I'm not sure what's going wrong

Here's what the STATUS_CAP code looks like:

    @CapabilityInject(IStatus.class)
    public static final Capability<IStatus> STATUS_CAP = null;

And also the lazyStatus incase that's important

private static final LazyOptional<IStatus> lazyStatus = LazyOptional.of(Status::new);

 

Edit: It also looks like the getCapability function isn't used at all? At least that's what I've gotten from placing random System.out.println's everywhere. I'm guessing I'm not registering the capability correctly 

    @SubscribeEvent
    public void attachCapability(AttachCapabilitiesEvent<Entity> event) 
    {
        if (!(event.getObject() instanceof PlayerEntity)) return;

        event.addCapability(new ResourceLocation(Reference.MODID, "status"),
                new StatusProvider());
    }

but this seems to be what the docs say to do so I'm not sure if anything's wrong with it

[poopoodice]

Is the event triggered?

[ImNotJahan]

It wasn't!

This isn't really a good thing but now I figured out that it shouldn't be on the mod bus, and so now it's attaching correctly and the getCapability function is being ran, and everything else seems to be working even without networking (for now at least) so thank you very very much
