[1.13.2] How to detect when a certain item is dropped?

[ketchup_god]

I am trying to test if a certain item has been dropped. I am aware of the ItemTossEvent event, but I'm not really sure how to use it. Any help would be appreciated!

Subscribe to the ItemTossEvent.

Use ItemEvent#getEntityItem (ItemEvent is the super class of ItemTossEvent) to get the EntityItem thrown.

Thanks for the quick reply, I will try it out!

Okay, so how do you do that exactly?

 

I have been trying to make it work for a while now, and it still won't do anything. Here's my current code to tell the player when they drop anything

@Mod(Reference.MODID)
public class DroppedItem
{
	@SubscribeEvent
	public void onItemTossEvent(ItemTossEvent itemTossEvent) {
		Minecraft.getInstance().player.sendChatMessage("you dropped something");
	}
}

The annotation on an event bus subscriber should be @EventBusSubscriber.

Also make the onItemTossEvent static (refer to this picture for more explanation on when event bus subscriber should be static).

That is going to crash on a server. Hopefully you are only using it temporarily for debugging purposes.
