Observing Inventories

[simicats 2]

Hi there, 

I've been working on tickable TileEntities which operate on inventories of neighboring blocks.

To reduce the occupied tick-time it would be fantastic to have the observer only update whenever the inventory had been changed.

I've heard that filled Hoppers attached to large inventories with no remaining space can cause quite an impact, therefore I wondered if there was common practice in the world of Forge for listening to another TEs' IItemHandler efficiently.

 

Example: Some detector circuit similar to a Comparator emitting a signal when the contents of a chest next to it match a number of conditions. The conditions would only have to be checked whenever the contents changed.

 

Thanks for your time!

onNeighborChange(BlockState, IWorldReader, BlockPos, BlockPos) (onNeighborChange(IBlockAccess, BlockPos, BlockPos) for 1.12.2) will be called on your Block when a neighboring tile entity changes (that includes inventories). You can then re-check the corresponding position.
