1.11 Implementing an inventory for entities/tileentities. in Modder Support Posted November 28, 2016 · Report reply Hello, in 1.10, I made use of IInventory to handle my inventory needs, but with 1.11, some of the ItemStackHelper methods I was using seems to not like my approach of implementing my inventory. I have seen the minecraft chest make use of : NonNullList<ItemStack> = NonNullList.<ItemStack>func_191197_a(27, ItemStack.field_190927_a) (different than what I have been using: ItemStack inventory = new ItemStack) so I decided to search around of the forums. That only lead to more confusion, as I saw some posts stating IInventory is not supposed to be used anymore, and a capabilities system should be used now (I think it was IStorage??)? So all of that being said, I am wondering if anyone has a link, guide, video, or example of how to properly implement and inventory to entities/tileentities? Any information would be greatly appreciated. I have been stewing on this for over a week now, and nothing seems to really make sense. Thanks!
