How do I detect (on the server) if a player is swinging a sword? I want to make an enchantment that lets you deflect arrows like ghast fireballs, but I can't find an event that fires when the player left clicks. I looked into sending a packet from the client to the server when there's a left click on the client side, but I couldn't figure out how to send the server an event object for the left click event. If theres an easier way to do this, I'd love to hear it.

I think you want the PlayerInteractEvent.LeftClickEmpty and AttackEntityEvent events

Will attackEntityEvents work with projectiles?

Also, leftclickempty only works on the client.

events

IIRC all projectiles are entities except for eggs

Thats... oddly specific

 

Thats the only reference to it I could find, I think its been changed in newer versions tho

Edit: https://bugs.mojang.com/browse/MC-31338 yeah, it was changed ages ago

Lol, this codebase scares me sometimes with how janky it is. I seem to recall arrows not responding to being hit with a sword, but I'll test again and report back.

@Cadiboo I just tested and AttackEntityEvent event by firing arrows at myself from a dispenser and swinging a sword at them. It appears that arrows dont fire the event.

 

Code:

 

@SubscribeEvent
	public static void event(AttackEntityEvent event)
	{
		if(event.getEntity() instanceof IProjectile)
		{
			System.out.println("x");
		}
	}

EDIT: Holy shit I'm dumb, I forgot to register the event.

 

EDIT2: After registering the event, it still doesn't work.

im dumb

Try the onProjectileImpact event maybe? You could also check the arrow code & possibly submit a PR to forge
