If I wanted to do it like that for a custom item that takes parameters in the constructor depending on things within the entity class, how can I do that? I thought that would be the way to do it.

That makes sense, sorry. However, why does doing this in my entity class, mean the item that I pick up disappears after I exit the world? if(this.isDead && !this.worldObj.isRemote) { this.worldObj.spawnEntityInWorld(new EntityItem(this.worldObj, posX, posY, posZ, new ItemStack(new ItemBow().setUnlocalizedName("bow").setTextureName("bow")))); }

They need to be used in multiple methods and I need to remove the first constructor.

I thought because I am using NBT that the variables would be different as they get saved and then set again, or am I missing something? When I have two different items they work fine, as if they were two different items.

There is the item code: package com.blocklings.items; import net.minecraft.entity.Entity; import net.minecraft.entity.EntityList; import net.minecraft.entity.IEntityLivingData; import net.minecraft.entity.player.EntityPlayer; import net.minecraft.item.Item; import net.minecraft.item.ItemStack; import net.minecraft.nbt.NBTTagCompound; import net.minecraft.util.MathHelper; import net.minecraft.util.StatCollector; import net.minecraft.world.World; import com.blocklings.entity.EntityBlockling; import com.blocklings.main.Blocklings; public class ItemBlockling extends Item { public EntityBlockling blockling; public int level, xp, upgrade, special; public String blocklingName, name; public ItemBlockling() { super(); this.setUnlocalizedName("blockling"); this.setMaxStackSize(1); this.setTextureName(Blocklings.MODID + ":" + "blockling"); } public ItemBlockling(String name, int level, int xp, int upgrade, int special) { super(); this.setUnlocalizedName("blockling"); this.setMaxStackSize(1); this.setTextureName(Blocklings.MODID + ":" + "blockling"); blocklingName = name; this.level = level; this.xp = xp; this.upgrade = upgrade; this.special = special; } @Override public void onUpdate(ItemStack itemStack, World world, Entity entity, int i, boolean b) { itemStack.stackTagCompound = new NBTTagCompound(); if(blocklingName.length() > 0) { name = blocklingName; } else { name = "Blockling"; } for(int j = 0; j < 1; j++) { itemStack.stackTagCompound.setString("name", blocklingName); itemStack.stackTagCompound.setInteger("level", level); itemStack.stackTagCompound.setInteger("xp", xp); itemStack.stackTagCompound.setInteger("upgrade", upgrade); itemStack.stackTagCompound.setInteger("special", special); } level = itemStack.stackTagCompound.getInteger("level"); } @Override public ItemStack onItemRightClick(ItemStack itemStack, World world, EntityPlayer player) { EntityBlockling blockling = new EntityBlockling(world, level, xp, upgrade, special); blockling.setLocationAndAngles(player.posX, player.posY, player.posZ, MathHelper.wrapAngleTo180_float(world.rand.nextFloat() * 360.0F), 0.0F); blockling.onSpawnWithEgg((IEntityLivingData)null); if(!world.isRemote) world.spawnEntityInWorld(blockling); if(!world.isRemote) world.playSoundAtEntity(blockling, "fireworks.twinkle1", 1.0F, 1.0F); if(!world.isRemote) itemStack.stackSize--; return itemStack; } @Override public String getItemStackDisplayName(ItemStack itemStack) { return name; } }

My custom item leaves my inventory after I save and quit the world then enter again, no clue why.

How do I do that though, as the parameters don't contain an x, y, or z coordinate.

I am trying to make an item spawn my mob, but I don't understand how to do it. I thought this method would do it but for some reason this doesn't work, nothing spawns: @Override public ItemStack onItemRightClick(ItemStack itemStack, World world, EntityPlayer player) { if(!world.isRemote) world.spawnEntityInWorld(new EntityBlockling(world, level, xp, upgrade, special)); return itemStack; } I looked in the normal spawn egg code but couldn't figure it out.

I fixed it. The tile was null because I think it was destroyed before I could actually set it to anything or something.

Here is the entire crash report:

I did that but sadly, it had no effect.

I will try that and let you know. This is for two of my custom blocks placed near each other...

I am having a bit of a problem with a null pointer exception. Whenever I try to System.out.println(tile.getCoal()); which I thought should work I just get a null pointer at that line. I don't really know why though, any help would be much appreciated, thanks.

Okay thanks, I think I know how to do that.

I set everything up now with my 7 integers in the tile entity class. I am now wondering how I access them in my actual block class.
