Class SimpleInventory

java.lang.Object
net.minecraft.inventory.SimpleInventory
All Implemented Interfaces:
Inventory, RecipeInputProvider, Clearable
Direct Known Subclasses:
ComposterBlock.ComposterInventory, ComposterBlock.DummyInventory, ComposterBlock.FullComposterInventory, EnderChestInventory
public class SimpleInventory extends Object implements Inventory, RecipeInputProvider
A generic implementation of Inventory. This is used in a number of places, mostly:
  • To store the input of a ScreenHandler while it is open. The inventory is stored as a field, and the screen handler will have a slot backed by that inventory.
  • When defining the clientside constructor for a ScreenHandler subclass. The contents of the inventory will then be automatically synced from the serverside screen handler, which queries the original inventory.
  • For entities and block entities which do not interact with hoppers and therefore do not need to implement Inventory themselves.

Changes to the inventory can be listened to either by subclassing this and overriding markDirty(), or by using addListener(net.minecraft.inventory.InventoryChangedListener).

    • markDirty

      public void markDirty()
      Marks the inventory as modified. Implementations should call this method every time the inventory is changed in any way.
      Specified by:
      markDirty in interface Inventory
      See Also:
      API Note:
      Implementations should mark the inventory for synchronization or saving in this method. Since this is called frequently, it is not recommended to synchronize or save the inventory directly in this method. If this inventory is implemented in a block entity, then it should always call super.markDirty(); to ensure the block entity gets saved.

    • canPlayerUse

      public boolean canPlayerUse(PlayerEntity player)
      Returns whether player can use this inventory.

      Specified by:
      canPlayerUse in interface Inventory
      Returns:
      whether player can use this inventory
      See Also:
      API Note:
      Implementations should check the distance between the inventory holder and player. For convenience, this interface offers two methods used by block entities to implement this check.
