[1.11] ItemStackHandler Capability deletes contents after every tick?

[Pingubro]

So it is me again...

 

I am trying to mimic ISided ness with two ItemStackHandlers.

The guy which is only used internal for my stuff works just fine.

But the second one used as output seems to delete its contents 

every tick or so.

I tried debugging my Method it was working fine when I only debug one crafting cyclus

but when I debbug every tick it seems to delete its contents straigth after 1 tick.

 

My Block(performs setting of Inventory contents for Crafting ingredients)

My TileEntity

 

Maybe I made a dumb mistake but everything else is working as intended I can only not find the

derp that deletes my InventoryContents.

 

Thanks for helping me

Yeah, 

I already thought about this but its regarding this Capability

https://github.com/hnsdieter/FluxedThings2/blob/master/src/main/java/pingubro/fluxedthings/tileentity/TileCrystalCauldron.java#L45

and both methods seem not to effect the contents

You need to clone the recipe's result stack.

[Pingubro]

ItemStack output = recipe.getOutput().copy();

So I did now but it still doesnt work the output is still empty.

I cant get the Item from rigthclicking oder destroying my Block

Boot up the debugger and step-through it.

[Pingubro]

Ok I stepped through my code with prints... (dont know how to use IntelliJ properly)

As mentioned the crafting works the setting of my Output works and the Output is the same after the current Tick.

But in the next tick without doing everything my Output is empty again without modifying it in my code till I activate or breaking 

my Block.

Is there a way to watch an Object in IntelliJ while debugging it showing me all operations done with my Object?

[Draco18s]

Ah!

I know what it is.

 

Your TE changes your blockstate when it gets an output item.

 

Changing the block state results in the TE itself being deleted and recreated.  You need to override...shouldRefresh in your TileEntity like so.

Thank you very much now it works fine.

I would have never come up with a solution myself I did not know

about this.

[Draco18s]

It's a thing that vanilla did in 1.10 and Forge never supplied a good default (or never altered the method to supply a good default, I'm not sure which).

The default method is "replace the TE if the TE is not a vanilla TE" which is pretty much worthless.  Are there TEs that should refresh when the blockstate changes? Probably. Is it the vast majority? No.
