[SOLVED] [1.15.1] Confused why entityDropItem fire multiple time

Recommended Posts

Hi All,

 

Looking for some help here.  I went back to my Udemy Java course and refreshed on the Lists and For each loops to check my thinking, but I am still perplexed.

 

The block does what I want it to do, EXCEPT that the entityDropItem fires any where from 9-12 times each time I spawn a Zombie to test the block.

 

Here is my code:

package com.kwpugh.gobber2.blocks;

import java.util.List;
import java.util.Random;

import javax.annotation.Nullable;

import com.kwpugh.gobber2.Gobber2;

	}

	//Start it up if right-clicked on

			for(Entity mob : mobs)

					BlockPos posUp = pos.up();		
					BlockState flaming = ((FireBlock)Blocks.FIRE).getStateForPlacement(world, posUp);
					world.setBlockState(posUp, flaming, 11);
				}
			   
				// These types of mobs are excluded

				}
				
				if(mob instanceof ZombiePigmanEntity || mob instanceof ZombieEntity || mob instanceof ZombieVillagerEntity)
				{
					((MobEntity) mob).spawnExplosionParticle();
					((LivingEntity) mob).setHealth(0);
					mob.entityDropItem(Items.GOLD_NUGGET,1);
					Gobber2.logger.info("drop executed for " + mob + "," + " values of mobs " + mobs);		
				}
		   }
	   }
   }
    
	@OnlyIn(Dist.CLIENT)
	public void addInformation(ItemStack stack, @Nullable IBlockReader world, List<ITextComponent> tooltip, ITooltipFlag flag)
	{
		super.addInformation(stack, world, tooltip, flag);				
		tooltip.add(new StringTextComponent(TextFormatting.BLUE + "The Looter "));
		tooltip.add(new StringTextComponent(TextFormatting.GREEN + "Range: 18 blocks"));
	}
}

 

I have been going through this for hours, trying different things to no avail.   Help please.

 

Regards.

1) Your "these mobs are excluded" block is irrelevant. You only care about players and zombies, which you have blocks for. Any entity that is not those things does nothing already, there's no reason to grab everything else (you're not grabbing mod added entities for instance!) and skipping them is pointless.

2) ZombiePigman extends Zombie, so that check is extraneous as well.

3) You're setting mob's health to zero, but the entity is not immediately made dead and removed for at least the next tick, but you aren't checking to make sure that the mob is still alive before doing your thing.

4) TranslationTextComponent (and applyTextStyle(...)) exists. Use it.

DO NOT PM ME WITH PROBLEMS. No help will be given.

1) Good point, that is code that I will delete

2) ditto

3) I did not know it was not immediate.  In 1.12.2 I had used  ((EntityLivingBase) entity).setDead();  which had worked fine, but appears gone in 1.15.1.  Also, see code snippet for how I had tried to check if it was alive before doing the drop.   That did not work.

4.) I'll take a look at the TranslationTextComponent.

 

				if(mob instanceof ZombiePigmanEntity || mob instanceof ZombieEntity || mob instanceof ZombieVillagerEntity)
				{
					((MobEntity) mob).spawnExplosionParticle();
					((LivingEntity) mob).setHealth(0);
					if(!mob.isAlive())
					{
						mob.entityDropItem(Items.GOLD_NUGGET,1);
						Gobber2.logger.info("drop executed for " + mob + "," + " values of mobs " + mobs);	
					}
				
				}

I was going back through the Entity.class to look for other options.   I found remove(boolean).

 

This code does what I need, but is it the intended usage of remove(boolean)?

				if(mob instanceof ZombieEntity || mob instanceof ZombieVillagerEntity)
				{
					((MobEntity) mob).spawnExplosionParticle();
					mob.remove(true);
					mob.entityDropItem(Items.GOLD_NUGGET,1);
				}

((LivingEntity) mob).setHealth(0);

if(!mob.isAlive()) { ... }

isAlive is going to return false if the mob's health is zero...
