So, I have this code.
What I wanna do is that when the item is in my inventory, the player is set on fire.

It isn't working... Any Idea on what is the problem (Eclipse shows me no problem)

I almost forgot to say, I used ACATIA_BUTTON just to test and I'm kinda new at this.

 

package com.riceandcheese.jademod.common.items;

import net.minecraft.entity.player.PlayerEntity;
import net.minecraft.item.Item;
import net.minecraft.item.Items;
import net.minecraftforge.event.TickEvent.PlayerTickEvent;
import net.minecraftforge.eventbus.api.SubscribeEvent;

public class SpecialItem4 extends Item {

    public SpecialItem4(Properties properties) {
        super(properties);
    }
    @SubscribeEvent
    public void onTickPlayerEvent(PlayerTickEvent event){

        if(event.player instanceof PlayerEntity){
            PlayerEntity player = (PlayerEntity) event.player;
            if(player.inventory.hasItemStack(Items.ACACIA_BUTTON.getDefaultInstance())) {
                player.forceFireTicks(21);
            }
        }
    }
}

you shouldn't be putting event handlers in Item classes, but in specific event handler classes (separation of concern). your event handlers then should be registered to the Event Bus, so that the event listeners actually fire.

The linked doc page explains it further

Several things don't make sense about your code.

• Do you want to use an item that is not added by your mod (e.g. the acacia button)? If so, why do you have a class that extends Item then?
• If you want to do it for an item added by your mod (e.g. the "SpecialItem4"), why do you use an event for this? Override inventoryTick in your Item class instead.

Ok so, this is my EventHandler class:

package com.riceandcheese.jademod.core.event;

import com.riceandcheese.jademod.Jademod;
import com.riceandcheese.jademod.core.init.Iteminit;

import net.minecraft.entity.player.PlayerEntity;
import net.minecraftforge.event.TickEvent.PlayerTickEvent;
import net.minecraftforge.eventbus.api.SubscribeEvent;
import net.minecraftforge.fml.common.Mod.EventBusSubscriber;
import net.minecraftforge.fml.common.Mod.EventBusSubscriber.Bus;

@EventBusSubscriber(modid = Jademod.MOD_ID, bus = Bus.FORGE)
public class EventHandler {
	@SubscribeEvent
	public void onTickPlayerEvent(PlayerTickEvent event){

		if(event.player instanceof PlayerEntity){
			PlayerEntity player = (PlayerEntity) event.player;
			if(player.inventory.hasItemStack(Iteminit.fire_fragment.get().getDefaultInstance())) {
				player.forceFireTicks(21);
			}
		}
	}
}

It's still not working (fire_fragment is the item that's gonna make it happen)

*Squint*

Worked thanks!
If anyone wants the code:

package com.riceandcheese.jademod.common.items;

import com.riceandcheese.jademod.core.init.Iteminit;

import net.minecraft.entity.Entity;
import net.minecraft.entity.player.PlayerEntity;
import net.minecraft.item.Item;
import net.minecraft.item.ItemStack;
import net.minecraft.world.World;

public class SpecialItem4 extends Item {

	public SpecialItem4(Properties properties) {
		super(properties);
	}
	@Override
	public void inventoryTick(ItemStack stack, World worldIn, Entity entityIn, int itemSlot, boolean isSelected) {
		if(entityIn instanceof PlayerEntity){
			PlayerEntity player = (PlayerEntity) entityIn;
			if(player.inventory.hasItemStack(Iteminit.fire_fragment.get().getDefaultInstance())) {
				player.forceFireTicks(30);
			}
		}
		super.inventoryTick(stack, worldIn, entityIn, itemSlot, isSelected);
	}
}
