I have an item that I would like to give the player poison when it is in their main or offhand, and nothing if it is not. Is there any way to achieve this effect?

Override Item#inventoryTick.

Cool, but where would I override this? And how? I set up a class called PoisonIvyLeaf to check if this item is in the hand, but I'm not sure where to implement inventoryTick to check for that. Should I set up a SubscribeEvent?

You override this method in the item class for the item you want to have this effect.

here's what I have so far

package item;

import mmyron.mmyronsqol.lists.ItemList;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.item.Item;
import net.minecraft.item.ItemStack;
import net.minecraft.potion.Potion;
import net.minecraft.potion.PotionEffect;

public class ItemPoisonIvyLeaf extends Item{

	public ItemPoisonIvyLeaf(Properties properties) {
		super(properties);
	}
	
	private void onPlayerTick(EntityPlayer player) {
		ItemStack itemInSlot = player.inventory.getStackInSlot(0);
		if(itemInSlot.getItem() == ItemList.poison_ivy_leaf) {
			player.addPotionEffect(new PotionEffect(Potion.getPotionById(19), 5, 0));
		}
	}

}

I feel like this would work, but now I'm clueless as to how to register the item in the registry lol

How would I call this item class in the registry in my main class?

One of these things is not like the other.

Right, so I changed that to override inventoryTick (it wasn't showing up correctly for me earlier), and i got this

	@Override
	public void inventoryTick(ItemStack stack, World worldIn, Entity entityIn, int itemSlot, boolean isSelected) {
		
		if(stack.getItem() == ItemList.poison_ivy_leaf && isSelected) {
			
		}
	}

However, I'm unable to use the addPotionEffect, since the entityIn doesn't seem to be a player?

 

EDIT: Figured it out.

Spoiler

@Override
	public void inventoryTick(ItemStack stack, World worldIn, Entity entityIn, int itemSlot, boolean isSelected) {
		
		if(stack.getItem() == ItemList.poison_ivy_leaf && isSelected) {
			if(entityIn instanceof EntityPlayer && !entityIn.has) {
				((EntityPlayer) entityIn).addPotionEffect(new PotionEffect(MobEffects.POISON, 20, 0));
			}
		}
	}
