i want to that when a player picked up a thing so he verified that is a potato 

but i don't know how to do it just using Minecraft id and i don't know how to get from an item the 

Minecraft id to check if it "Minecraft:potato"

the code is here...

package com.shidopitzel.mymod.events;

import com.shidopitzel.mymod.MyMod;
import com.shidopitzel.mymod.init.BlocksInit;

import net.minecraft.entity.LivingEntity;
import net.minecraft.item.Item;
import net.minecraftforge.event.entity.player.EntityItemPickupEvent;
import net.minecraftforge.eventbus.api.SubscribeEvent;
import net.minecraftforge.fml.common.Mod;
import net.minecraftforge.fml.common.Mod.EventBusSubscriber.Bus;
import net.minecraftforge.registries.ObjectHolder;;;


@Mod.EventBusSubscriber(modid = MyMod.MOD_ID,bus = Bus.FORGE )
@ObjectHolder(MyMod.MOD_ID)

public class PotatoPickUpEvent {
	
	@SubscribeEvent
	public static void PotatoPickUpEvent(EntityItemPickupEvent event) {
		
		LivingEntity livingEntity = event.getEntityLiving();
		
		MyMod.LOGGER.info(livingEntity.getEntityString() + " picked owner " + event.getItem());
	}
}

 

how can i check the Minecraft id of "event.getItem" but first i want to print it in the console and after do a condition

Why check the ID? You can compare it to Items.POTATO

I will try but how we can copare it is the "equals" command ??

 

Do you know Java?

yes 

Items are singletons, you can directly check for equality

the world is unlogic to understand i write to change event.getItem().getItem().getItem() and it is write me in the console"potato" and when it it other thing like oak planks it is write me in the console "oak_planks" so i just need to do a condition if it is equal to "potato" just so easy but the answer was in front my eyes

Don't compare the names, compare the items! (Or are you checking for equality with user input?)

How do you check for reference equality in Java?

yes i do that

if (event.getItem().getItem().getItem().equals(Items.POTATO)) {
		MyMod.LOGGER.info("You picked " + event.getItem().getItem().getCount() + " potato");
}

for the moment

Why are you chaining getItem()? Nevermind, I didn't realize the number of layers the item itself is wrapped in

and that is not how you check reference equality.

event.getItem() will return EntityItem

herpy derp

because it is show me in the console like in picture capture all this thing and can do nothing 

in capture.jpg and the name of the item changing in the language you choose to minecraft

this is in catala language it is really changing between this two language

Why do you need to use the item name? Are you doing something based on something that gets typed in?

because a youtuber that did a video of making mods from ideas of his subscriber and he make a item that pick number of potatoes and add and save it in a value that when he will put it in the the four recipes it will be give again the all the potatoes in stack by stuck he do it for his server maybe you know it is "Palladium" it is Minecraft with mods luncher for multiplayers and in this "palladium" Minecraft there is this item for shortly it is for farm potato to get xp for the "farmer job" 

 

What you just typed doesn't make much sense in English, and none of it negates the fact that comparing the item that gets picked up to Items.POTATO is more efficient than comparing the registry name.

Never compare registry names when you can just compare the two references.

In your case you just want to know if the item is an instance of potato, so your previous check should work (although it would be better with ==).

when I test with "==" it is show me error 

so I used ".equals(Items.POTATO)"

and it is more easy because it is compare two items it is not a string it is an object and object compare with string I don't think it is work

event.getItem().getItem().getItem() == Items.POTATO;
