Hey guys I am making a mod and I want to add a block that when you insert something in the first slot of the gui it comes out like something else in the other.
Here is the code

I mean you could check out the crafting table code

tired radish Apr 17, 2025, 2:07 PM

#

yeah I did but it didnt help that much because the custom block is registered as an normal block nt an advanced one and when I made the Custom block with the entities files and screen files it had so many errors

#

austere stratus I mean you could check out the crafting table code

wait I will try again

austere stratus Apr 17, 2025, 2:09 PM

#

tired radish wait I will try again

CraftingScreenHandler has a method called updateResult, which gets called when anything in the grid changes

tired radish Apr 17, 2025, 2:13 PM

#

ok

#

wait

austere stratus Apr 17, 2025, 2:15 PM

#

tired radish wait

In your PressingTableScreenHandler, where ur making a new SimpleInventory, add curly braces around it instead of just making a new SimpleInventory, or whatever u call it, and in there override markDirty

#

Im pretty sure markDirty gets called whenever an inventory slot changes

austere stratus Apr 17, 2025, 3:13 PM

#

Im not really sure, thats about all i know

tired radish Apr 17, 2025, 3:13 PM

#

Should We ask someone else

#

Or Do you know someone else

austere stratus Apr 17, 2025, 3:14 PM

#

I dont rlly know anyone good at coding

#

ask in mod dev 1 or 2

tired radish Apr 17, 2025, 3:14 PM

#

ok

lime mesa Apr 17, 2025, 3:16 PM

#

You have the Screen and Menu for it right ?

tired radish Apr 17, 2025, 3:16 PM

#

yes if you mean the screen java files and entity

lime mesa Apr 17, 2025, 3:18 PM

#

wait what you want to do first tho ? Like what Block with GUI, what should it do

tired radish Apr 17, 2025, 3:19 PM

#

when you r-click the block it opens a gui with two slots,
In the first one you put a listed item in the code
And in the second one it comes out like a different Item

lime mesa Apr 17, 2025, 3:20 PM

#

they should stay in the block or not ?

tired radish Apr 17, 2025, 3:20 PM

#

no

lime mesa Apr 17, 2025, 3:20 PM

#

bcz then I think you dont need a BlockEntity for that and you can do everything in the Menu or Screen

tired radish Apr 17, 2025, 3:20 PM

#

like the crafting table but with one slot to craft and one slot for result

#

If you want I can send you the code, just tell me which one

lime mesa Apr 17, 2025, 3:21 PM

#

and the block opens the menu atleast ?

tired radish Apr 17, 2025, 3:22 PM

#

doesnt the IDE also tells you if you have missing code?

lime mesa doesnt the IDE also tells you if you have missing code?

wdym

lime mesa Apr 17, 2025, 3:28 PM

#

you cant init the class with the variable's type and name as parameter

tired radish Apr 17, 2025, 3:29 PM

#

ok [ but because I am a new dev can you te me what to do in my code ]

lime mesa Apr 17, 2025, 3:31 PM

#

you need to learn for yourself better than asking others basic java but, you cant use PlayerInventory playerInventory as parameter, you have to use an already existing variable

tired radish Apr 17, 2025, 3:31 PM

#

ok i will try, thanks for the help
