Prevent Hopper input/extraction

[BeardlessBrady]

Wondering how I am able to prevent hopper interaction when using capabilities. I can just hack it by pointing it to a dummy ItemStackHandlers for extraction. This however wont stop input. Any ideas?

Or just not return them when a side is passed.

If I return null it crashes

Crashes when I place a hopper under the block

Ignore the if states for facing, its for other purposes later on. Should be the same result without

Also is there a way to detect if its pulling or pushing?

You cannot return null.

what do I return if I don't want it to interact with any slots then?

return super.getCapability(capability, facing);

Still crashes when I do that

Oops I see that your hasCapability always returns true when they are looking for a IItemHandler one. You need to make the same checks and return false.

thank you very much!. Last question, is there an easy way to detect the difference between inserting and outputting with a hopper, or any other pipe type item

There are two ways. You can assign your own ID to each slot and handle the implementation your self or add internal methods that only your TE will use in a custom IItemHandlerModifiable.

Alright. Thanks so much for the help, much appreciated

Because of this my hasCap method returns

getCap(...) != null

just to avoid the headache.
