I searched for the past few hours on if there are any events for commands.

I would like to just have a simple command that when executed, writes something in chat.

How can I do this?

Is there any built-in event for something like that?

I've seen a few tutorials but they are all from 2012 and dont work anymore.
 

Thanks in advance!

Edit: Sorry if I am being dumb. I just started with minecraft forge. I have a pretty good knowledge of java tho.

Oh. Thanks!

One question: Is there any way I can start the development client using gradlew runClient with no minecraft debugging? Because Its kinda hard to see System.out.println like this...

Sorry..
But I dont totally get how you mean that.
Is this a @SubscribeEvent?

Can you maybe send a small code snippet?

The things like 'joined world xyz' and 'Entry x'

 

Nevermind that haha. I am sorry for being dumb there.

 

But my event isnt registering?

 

@SubscribeEvent
    public void registerCommandsEvent(RegisterCommandsEvent event) {
        LOGGER.info(event);
        LOGGER.info("Test");
        //playerIn.addChatMessage(TextComponent("test"));
    }

Define "isn't registering".

Show how you registered your event handler.

It just doesn't fire when I send a command.

This is my registering:
 

MinecraftForge.EVENT_BUS.register(this);

Show more of your code. That should work fine.

    }
}

 

Oh yes that was just a test from me. I removed it in the build

Its still not working.

When should It fire?

On every message that starts with a slash right?

No. It fires at startup so you can register your commands.

Ok nice but how do I actually make a command then

Where can I find those?
