[Solved]Spawning an Item entity in world with NBTdata and information added

Recommended Posts

I have a throwable item, and when the entity that you get from throwing the item hits the ground, it needs to drop the exact item that you threw. I already can spawn a normal ItemStack, but it doesn't have NBT data or anything from my addInformation in my Item class.

 

This is my line to throw the entity in my Item file:

world.spawnEntityInWorld(new EntityKanokaTeleportation(world, entityPlayer));

 

and Here's my Entity File:

package com.eastonium.bionicle.kanoka;

import com.eastonium.bionicle.Bionicle;

import net.minecraft.block.Block;
import net.minecraft.entity.EntityLivingBase;
import net.minecraft.entity.item.EntityItem;
import net.minecraft.entity.player.EntityPlayerMP;
import net.minecraft.entity.projectile.EntityThrowable;
import net.minecraft.item.ItemStack;
import net.minecraft.nbt.NBTTagCompound;
import net.minecraft.util.MathHelper;
import net.minecraft.util.MovingObjectPosition;
import net.minecraft.world.World;
import net.minecraftforge.event.entity.living.EnderTeleportEvent;

public class EntityKanokaTeleportation extends EntityThrowable
{	
public EntityKanokaTeleportation(World par1World)
{
	super(par1World);
}

public EntityKanokaTeleportation(World par1World, EntityLivingBase par2EntityLivingBase)
{
	super(par1World, par2EntityLivingBase);
}

public EntityKanokaTeleportation(World par1World, double par2, double par4, double par6)
{
	super(par1World, par2, par4, par6);
}

/**
 * Called when this EntityThrowable hits a block or entity.
 */
protected void onImpact(MovingObjectPosition par1MovingObjectPosition)
{		
	if (!this.worldObj.isRemote)
	{
		ItemStack discDrop = new ItemStack(Bionicle.kanokaTeleportation); //This doesn't have any NBT data when it is dropped
		if(this.worldObj.getGameRules().getGameRuleBooleanValue("doTileDrops") && par1MovingObjectPosition.entityHit == null){
			this.worldObj.spawnEntityInWorld(new EntityItem(this.worldObj, this.posX, this.posY, this.posZ, discDrop));
		}
		this.setDead();
	}
}
}

 

is there a way I can send the info from the item I threw into the entity so it knows what to spawn as the new item?

And how?

Can you add an extra parameter to your entity?

You could probably do it so

world.spawnEntityInWorld(new EntityKanokaTeleportation(world, entityPlayer, stack.getTagCompound())); 

If you are calling it in the use item method in Item and have access to the ItemStack

And then set a variable in your entity to the tagcompound, then when it lands. After you've created the item stack you can do

discDrop.setTagCompound(this.thetagcompound)

 

So your entity would now look like this

 

package com.eastonium.bionicle.kanoka;

import com.eastonium.bionicle.Bionicle;

import net.minecraft.block.Block;
import net.minecraft.entity.EntityLivingBase;
import net.minecraft.entity.item.EntityItem;
import net.minecraft.entity.player.EntityPlayerMP;
import net.minecraft.entity.projectile.EntityThrowable;
import net.minecraft.item.ItemStack;
import net.minecraft.nbt.NBTTagCompound;
import net.minecraft.util.MathHelper;
import net.minecraft.util.MovingObjectPosition;
import net.minecraft.world.World;
import net.minecraftforge.event.entity.living.EnderTeleportEvent;

public class EntityKanokaTeleportation extends EntityThrowable
{	

private NBTCompound theTagCompound;

public EntityKanokaTeleportation(World par1World)
{
	super(par1World);
}

public EntityKanokaTeleportation(World par1World, EntityLivingBase par2EntityLivingBase, NBTTagCompound tagCompound)
{
	super(par1World, par2EntityLivingBase);
	this.theTagCompound = tagcompound;
}

public EntityKanokaTeleportation(World par1World, double par2, double par4, double par6)
{
	super(par1World, par2, par4, par6);
}

/**
 * Called when this EntityThrowable hits a block or entity.
 */
protected void onImpact(MovingObjectPosition par1MovingObjectPosition)
{		
	if (!this.worldObj.isRemote)
	{
		ItemStack discDrop = new ItemStack(Bionicle.kanokaTeleportation); //This doesn't have any NBT data when it is dropped
		if(this.theTagCompound != null) {
			discDrop.setTagCompound(this.theTagCompound);
		}

		if(this.worldObj.getGameRules().getGameRuleBooleanValue("doTileDrops") && par1MovingObjectPosition.entityHit == null){
			this.worldObj.spawnEntityInWorld(new EntityItem(this.worldObj, this.posX, this.posY, this.posZ, discDrop));
		}
		this.setDead();
	}
}
}
