TuxCraft Posted May 2, 2013 Posted May 2, 2013 How do I make an item reference itself as an itemstack? I've tried this itemToDrop = par3EntityPlayer.inventory.getCurrentItem(); But when I add it back into the inventory (par3EntityPlayer.inventory.addItemStackToInventory(itemToDrop) in another method the item disappears whenever I try to use it (onItemRightClick). I think it might be a server/client error but I'm very inexperienced with packets and such. I tried following the tutorial on the wiki but I really didn't understand it. Quote
LutzBlox Posted May 2, 2013 Posted May 2, 2013 To reference an item as an ItemStack, as simply use new ItemStack(Item.bucketEmpty); Replace Item.bucketEmpty with your item. To reference it in terms of a player's current item, simply use new ItemStack(par3EntityPlayer.inventory.getCurrentItem()); Hope this helps! Quote
TuxCraft Posted May 3, 2013 Author Posted May 3, 2013 Thanks for responding but I should probably add that I want to convert it to an itemstack so that it will keep its name, damage etc. So that means your first method wouldn't work. As for your second one par3EntityPlayer.inventory.getCurrentItem() returns an itemstack so you wouldn't be able to put it in the new itemstack annotation. If you wanted to do that you'd have to add .getItem() to the end. However that returns the item not the itemstack. Would I have to just get all the features I want the item to keep in different variables and store it in nbt or something? The main ones I'd like it to keep are the name, damage, and enchantment. For the name I found this method... itemToDropName = par3EntityPlayer.inventory.getCurrentItem().getDisplayName() For the rest I'm not sure what to do, please help. Quote
TuxCraft Posted May 4, 2013 Author Posted May 4, 2013 You can't "convert" to an ItemStack. Item and ItemStack are 2 different things. The Item class basically stores how the Item behaves. Only one instance of it exists for every Item. Then whenever it comes to inventory management, etc. the ItemStack comes in. It stores: - the Item it contains - the stack size - the damage value - possibly an additional NBTTagCompound (used e.g. for enchantments) You can access that NBTTagCompound by using stack.stackTagCompound (iirc). Just be sure to initialize it, because it is null by default. So for example to get damage would I do something like this? short damage = itemstack.stackTagCompound.getShort("Damage"); If it is, that isn't working for me. Quote

No, look at the ItemStack class itself, it has methods which names are self-descriptive: damage = stack.getItemDamage() Quote Don't ask for support per PM!

This is not how learning works.
TuxCraft Posted May 4, 2013 Author Posted May 4, 2013 No, look at the ItemStack class itself, it has methods which names are self-descriptive: damage = stack.getItemDamage() Thank you, I did that and so far so good, the only thing I'm not sure about enchantments. There is one function that in a comment says that it holds enchantments, but it returns an nbttagcompound. Here's what I have so far. public static ItemStack getItemStack(Item item, int i, String s) { ItemStack par1itemstack = new ItemStack (item, 1); par1itemstack.setItemDamage(i); if(s != null) { par1itemstack.setItemName(s); } return par1itemstack; } And this to add the item par1EntityPlayer.inventory.addItemStackToInventory(itemSpear.getItemStack(itemTool.item, damage, null)); Quote
