hello! The title explains everything. what i want to have is a random generated number pre item(which i do), but now i want to display that item. Do i still use the ItemStack.StackTagCompoud or what? Please help!

 

 

What i have so far:

 

 

 package com.gmod622.SickMod.item;



import java.util.List;

import com.gmod622.SickMod.tile.TileEntityLicense;

import net.minecraft.creativetab.CreativeTabs;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.item.Item;
import net.minecraft.item.ItemStack;
import net.minecraft.nbt.NBTTagCompound;
import net.minecraft.tileentity.TileEntity;
import net.minecraft.world.World;

public class LicenseItemClass extends Item {

public LicenseItemClass(int par1) {
	super(par1);
	this.setCreativeTab(CreativeTabs.tabMaterials);
}

public static int theRandom;

 public ItemStack onItemRightClick(ItemStack par1ItemStack, World par2World, EntityPlayer par3EntityPlayer) {
	//here you can use the information about the itemstack nbt
	//ex:


	 if(par1ItemStack.stackTagCompound == null){
		//here we know the nbt is null
		 par1ItemStack.stackTagCompound = new NBTTagCompound();
		}else {

		 theRandom = par1ItemStack.stackTagCompound.getInteger("myRandomNumber");
			if(theRandom == 0){
				//here we DONT have anythin on the stack compound
				par1ItemStack.stackTagCompound.setInteger("myRandomNumber", (int)(Math.random()*100000));//generate a number between 0-100 and place it on the nbt
			}else{
				System.out.println("the number of this item is: "+theRandom);
			}
 }


			return par1ItemStack;
	}





}

 

@SideOnly(Side.CLIENT)

    /**
     * allows items to add custom lines of information to the mouseover description
     */
    public void addInformation(ItemStack par1ItemStack, EntityPlayer par2EntityPlayer, List par3List, boolean par4) {}

In Item class.

Not sure if that is what you want.

I have a randomly generated number by using ItemStackNBT. if i would do that all of the ids will be the same on the cards

The first argument from that method is the ItemStack.

Get the id from its NBT, then add this id to the list. It will be displayed different for each.

Well, can you be just a little bit more discriptive

Something like:

// package here
// imports here

public class ItemRandomIDItem extends Item {
    // typical Item stuff here

    public void addInformation(ItemStack par1ItemStack, EntityPlayer par2EntityPlayer, List par3List, boolean par4 {
        NBTTagCompound stackCompound = ItemStack.getItemStackNBTTagCompount(); // whatever it is to get it
        int idToDisplay = stackCompound.getInteger("theRandomID");

        par3List.add("ID: " + idToDisplay);
    }

    // other Item stuff
}

this line:         NBTTagCompound stackCompound = ItemStack.getItemStackNBTTagCompound(); // whatever it is to get it

 

getItemStackNBTTagCompound isnt a method( I really newbie with ItemStacks and NBTs, sorry)

 

I know it isn't. I just wrote that with the comment saying, WHATEVER IT IS.

 

meaning I have no idea what the method is, but I know it's there...
