Game Chrashes on shift click on custom container [1.12.2]

[Schleim_time]

My game crashes by using shift click in my custom container, is there a way to fix that? i readed about @Override the transferStackinslot but i cant fint that anymore, maybe its gotten removed or got an other name?

Post your code and crash.

Funny thing is there is no crash and are nor errors, its seems to do an infinity loop or something but idk why, i heard you need to override transferstack or something but i have no plan how to use that. Can you see the minecraft workbench transferstack?

[DavidM]

Post your code then.

If you just extend Container then you need to override Container#transferStackInSlot, as you've said yourself.

It's still very much there on my end, so I don't know what your issue here is. Afaik the method didn't get renamed.

Ok i found out how to use that, i have to use that in the container bit o dont understand the syntax of that because its returning an itemstack, why will it still crash on return null instead of doing nothing on shift? Shift isnt important for me, so is it easy to only make that it return nothing? Or what can i do in there? Return an itemstack is weird i also tried return air but it still crashes instead of replacing the slot with air

ItemStacks cannot be null. They cannot be null because a stack of size zero is empty and should be treated as a non-existent stack.

This is why ItemStack.EMPTY exists.

So im only tring to do that shift will not crash, shift dont need a function but i have no plan how to do this, im not understanding the method

You still haven't post your code...

IIRC the method takes in a player and an index indicating who clicked on the slot and which slot he/she clicked on.

The method also handles the inventory manipulation during the shift-click process.

The ItemStack the method returns is the ItemStack that should remain in the slot after the shift-click operation.
