Is there a class that I can implement so that I may call the method, "onUpdate"?

 

I need something checked within an inventory every few ticks.

 

If I can call that method from within a class that extends container, or a class that implements IInventory, that would be ideal.

TickEvent.

 

For player-based inventory: PlayerTickEvent.

For mob-based: LivingUpdateEvent.

Note: player is also living, you can use that.

When using TickEvent, choose event.phase, otherwise code runs twice.

I think the OP wants his TileEntity to update.

I've forgotten the name of the method, but it should be easy to find. Is something like

doesRequireUpdates

, returns a boolean and the default implementation returns false (and does nothing else).

Thanks!  I'll take a look at that when I get back home.

Would that method happen to come from TileEntity?  I have a class that just implements IInventory, so I could extend TileEntity if that's the case.

Your TE needs to implement IUpdatePlayerListBox.

I'm unable to implement IUpdatePlayerListBox.  Must it be used on a TileEntity?  I don't have a TileEntity, because it's an item that accesses an inventory.

Item#onUpdate

is called every tick for each

ItemStack

of the

Item

in a player's inventory. If your inventory is tied to a player/mob rather than an item, you may want to use tick events as diesieben07 suggested.

 

IUpdatePlayerListBox

can be implemented by a

TileEntity

to receive an update every tick. You can also register other implementations of the interface to be updated by the server with

MinecraftServer#registerTickable

.

Note that items inside inventories that themselves don't tick (chests, actually most TileEntities, item frames) items don't get updates.
