Item Drop problem Minecraft Forge 1.7.10


Recommended Posts


I am trying to get a throwable entity to drop itself on impact. I have basically used to code from the snow ball and changed the damage and made it drop the itself as an item on impact. It works just fine when I throw it against a mob but when I throw it against a block it drops multiple floating icons, only one of which can be picked up. The rest just float there until you reload the world. any ideas as to why?


Hear is my code for EntityRangerThrowingKnife



import thelion1997.test.TestItems;

import net.minecraft.block.Block;

import net.minecraft.block.material.Material;

import net.minecraft.entity.EntityLivingBase;

import net.minecraft.entity.projectile.EntityArrow;

import net.minecraft.entity.projectile.EntityThrowable;

import net.minecraft.item.ItemStack;

import net.minecraft.util.AxisAlignedBB;

import net.minecraft.util.DamageSource;

import net.minecraft.util.MovingObjectPosition;

import net.minecraft.util.Vec3;

import net.minecraft.world.World;


public class EntityRangerThrowingKnife extends EntityThrowable {


private World world;

public EntityRangerThrowingKnife(World world) {


this.world = world;



public EntityRangerThrowingKnife(World world, EntityLivingBase entity) {

super(world, entity);

this.world = world;



public EntityRangerThrowingKnife(World world, double x, double y, double z) {

super(world, x, y, z);

this.world = world;





protected void onImpact(MovingObjectPosition mop) {


Block block = world.getBlock(mop.blockX, mop.blockY, mop.blockZ);


if (mop.entityHit != null) {


// I changed this to type 'float' and set to '15';

float knifeDamage = 15;



DamageSource.causeThrownDamage(this, this.getThrower()),



//This is where I drop the item

entityDropItem(new ItemStack(TestItems.itemRangerThrowingKnife), 0);


// I changed particles to "crit" particles at the point of impact

for (int l = 0; l < 4; ++l) {

this.worldObj.spawnParticle("crit", this.posX, this.posY,

this.posZ, 0.0D, 0.0D, 0.0D);



if (!worldObj.isRemote) {
