forge bus is for when the game starts

go and look what assertInventorySize does and A: replicate it using IItemHandler or B: remove it

where

why do you cast?

private LazyOptional<CombinedInvWrapper> optional = LazyOptional.of(() -> this will lazy initialized); EnderChestInventory enderChestInventory = player.getInventoryEnderChest(); IItemHandlerModifiable enderChestModifiable = new InvWrapper(enderChestInventory); invWrapper = new CombinedInvWrapper(enderChestModifiable, inventory); return invWrapper; that can be reduced to 1 line

is your event method static ?

why do you do then?

1 does getCapability return a IModItemHandler ? 2 does IModItemHandler extend IItemHandlerModifiable ?

show your container class

in serializeNBT return inventory.serializeNBT and in deserializeNBT call inventory.serializeNBT.deserializeNBT use CompoundNBT as Generic ICapabilitySerializable instead of INBT

yes but you need to save your inventory,instead of ICapabilityProvider implement ICapabilitySerializable

yes

the red box are the coordinates

what do you want to delay

yes

that is never going to work 1 tileB needs to extend tileA 2 change the code you need to change 3 in registerTileEntities register tileB as tileA

what are you trying to do

no but syncing nbt to the client does have a limit yes

what are you trying to do from a end user perspective
