[1.8] Save NBT-Tags for Item

[YoungErtu 5]

Hey guys, i'm working on a Item that allows the player to save a selected amount of mana into the item, this item will storage the mana and clicking right-click again, will release the mana and the player gets his stored Mana in the item back.

 

so this means i'll need 2 NBT-Tags one boolean to check if mana is stored in the item (or just check if the stored mana is 0 but i like the boolean version more), and one to save the amount of mana that is stored in the item, i already created the item and gui and just need help for finishing the item class.

 

Does somebody know how to save this Tags and use them?

Thanks for any help!

 

here the item class:

 

package youngertu.fairytail.items;

import java.util.List;

import net.minecraft.client.Minecraft;
import net.minecraft.entity.Entity;
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.ChatComponentText;
import net.minecraft.util.EnumChatFormatting;
import net.minecraft.world.World;
import net.minecraftforge.fml.relauncher.Side;
import net.minecraftforge.fml.relauncher.SideOnly;
import youngertu.fairytail.FairyTail;
import youngertu.fairytail.entity.extended.ExtendedPlayer;
import youngertu.fairytail.gui.GuiBatteryLacrima;
import youngertu.fairytail.network.PacketDispatcher;
import youngertu.fairytail.network.server.SpellToServer;
import youngertu.fairytail.network.server.UpdatePropsStats;

public class ItemBatteryLacrima extends Item{

 private final int STORED_MANA = 0;
  private final boolean IS_STORED = false;

public ItemBatteryLacrima() {
	this.setUnlocalizedName("batteryLacrima");
	this.setCreativeTab(FairyTail.tabFairyTail);
	this.setMaxStackSize(1);
}

/**
     * Called whenever this item is equipped and the right mouse button is pressed. Args: itemStack, world, entityPlayer
     */
    public ItemStack onItemRightClick(ItemStack itemStackIn, World worldIn, EntityPlayer playerIn)
    {	
    	ExtendedPlayer props = ExtendedPlayer.get(playerIn);
    	
    	if (!worldIn.isRemote)
        {
    		
    		Minecraft.getMinecraft().displayGuiScreen(new GuiBatteryLacrima());
    		
        }
	return itemStackIn;
    }
    

}

 

 

and i need methods to change the value of the tags outside the class e.g in the Gui when the button is pressed.

NBTdata is easy.

 

However, you are using a gui which means that the data you are setting is on the client which means you need packets.
