Caused by: java.lang.NullPointerException 2013-01-16 19:15:49 [iNFO] [sTDERR] at bartboy8.needynecessities.common.ItemPortableItem.onItemRightClick(ItemPortableItem.java:35) Line 35 is: nbt.setString("name", "YOLO"); Do u have any idea how I could set a variable to my itemStack?

Im attempting to use NBT Tags to save an array of block locations, matching with player names. I am trying to save this to my item. But it isn't working. I crash with this: public ItemStack onItemRightClick(ItemStack itemstack , World world, EntityPlayer player){ itemstack = player.getCurrentEquippedItem(); NBTTagCompound nbt = itemstack.getTagCompound(); if(!world.isRemote) { if(player.isSneaking()){ String i = nbt.getString("HELLO!"); player.sendChatToPlayer(i); }else{ nbt.setString("name", "YOLO"); } } return itemstack; } (Also this is my first mod and also just a test to see if it will work). If there is a better way to save block location and player names. Please say! Also I need it to still contain this info even after restart. I am trying to make a protection mod and have everything working besides this! Please help if you can
