Hey I followed your ItemInventory tutorial and it worked but for some reason the slots are all filled with the item that i used to open the gui. Any idea why this might be?
You probably set the contents of all the slots to be that item. Check your inventory's read and write NBT code.
@Override
public void markDirty() {
ItemStack stack = Minecraft.getMinecraft().thePlayer.getHeldItem(); // this line
NEVER NEVER NEVER use Minecraft.getMinecraft() - it is CLIENT side only, and the client does not save things.
The WHOLE point of the entire tutorial was showing how to store the ItemStack reference when the inventory is constructed so that you have it available when you want to save.
Index is very likely out of bounds because you either didn't remove the armor slots from your counting.
Also, using #onContainerClosed is not a bad idea, but the problem comes if the inventory is ever manipulated outside of the Gui/Container system, e.g. calling #setInventorySlotContents directly, which is completely possible, in which case having it save in #markDirty comes to the rescue.
#writeNBT should NOT be getting called when the inventory is opened; only when it is closed. Opening the inventory should be calling #readNBT. Both reading and writing NBT are usually only done on the server.
I recommend you re-read the tutorial, taking special care to read all of the code and code comments. It is pretty clearly explained, but if there is something you don't understand, feel free to ask.
Check your readNBT code - it should be assigning the ItemStacks directly to the inventory array, NOT calling #setInventorySlotContents. The reason is that #setInventorySlotContents is the one method that calls #markDirty, so you can't use it when reading the inventory.
Well you're calling #markDirty from somewhere, then. Right-click on that method in your inventory class and open the call hierarchy for it - that will show you all the places it is called.
I did but its only called in methods where something is changed also i found out (in the minecraft source) that the comment of markDirty says that its used for tile entities could this be the problem? Im using 1.8.9 btw.
Lol, no, that's not a problem. The code comments are submitted by people contributing to MCP, so whomever submitted that one saw that TileEntities used it and nowhere else (at that time, which was many Minecraft versions ago by now) so wrote that comment. Doesn't mean you can't use the method yourself for your own purposes.
Actually, looking at 1.8 code, #markDirty is called for the inventory from Slot#onSlotChanged, so you may not even need to call it yourself from your inventory implementation. Just remove anywhere in your code that calls #markDirty, but keep the implementation of #markDirty as is from the tutorial.
No difference i outcommented every line where i call markDirty myself but the Client Side still calls markDirty.
Well, either you are doing something wrong, or you are coding for 1.8.9 and something I don't know about has changed. I haven't tried porting this code to 1.8.9 yet, so I haven't sussed out any discrepancies.
If you are not using 1.8.9, post links to your code.
Seems your "Creating an Item that stores an Inventory" tutorial is outdated. When I copypaste the code, I get a whole bunch of errors saying the overrided methods don't even exist.
Are there any up-to-date tutorials for achieving this? Thanks.
EDIT: By up-to-date tutorials I mean tutorials for 1.8.9.
Don't copy / paste code from tutorials. That said, it is outdated as they completely overhauled tons of stuff between 1.8 and 1.8.9, including IInventory, IEEP, etc. They (Forge team) want you to use the new Capability system instead.

Hm, that is highly annoying. I'd hoped it would be a simple task to create an item that stores an inventory. I'm completely new to working with MC's GUI's and the associated classes and such, so it looks like I have quite the puzzle laid out before me, due to the lack of up-to-date tutorials.
1.7.10, i already have a block made, how would i convert it into a chest?
You need at least a Block, TileEntity, IInventory, Gui, and Container.
However, this tutorial does not cover TileEntity/Block-based inventories - I suggest you search for one that does and also take a look at vanilla chests.
