[1.19.2] Item container / block briefcase, "how to make an dispenser like menu to pop up from an item ?"

perromercenary00 · January 21, 2023

Good days

Im trying to remake the briefcase item from mi old mod i find and old video

I made this armours whit pockets and a interface to interact whit those pockets

i made this briefcase_item whit 9 slots if you right click whit the item in the hand its open a dispenser like interface from where you can interac and store items in the briefcase_item
if you right click the floor while crounching the briefcase would become a block and the items stored would go as nbtdata to the tileentity in the briefcase_block

if you right click the briefcase_block it would disapear returning as the briefcase_item to the player inventory whit all the items inside

all that was minecraft 1.8 before capabilities and that code is long lost

//########## ########## ########## ##########

now in 1.19.2

coping code from the dispenser and looking to the Kaupenjoe tutorials i manage to make this briefcase_panel and the item but im far from the behaveour of the 1.8 version

whit the help of the Kaupenjoe tutorials i fix the invisible texture problem and the data now is saved to the world soo the stored items persist inside the blockentity after close/open the game

but but but

###########

In this moment the menu pops when right clicking the block i want the dispenser menu to cameout but from the briefcase_item but no idea how to call an menu from an item

i need guidance whit that feature

can you help me with that

mi briefcase_block

i want the dispenser menu to cameout but from the briefcase_item but no idea how to call an menu from an item

Opening a menu from an item is pretty much the same way as doing so for a block: call `NetworkHooks#openScreen` and pass in the associated inventory which should be attached as a capability to the stack.

You cannot just create the list on the item itself since that would apply globally to all instances of the item in the stack and be incorrectly synced.

perromercenary00 · January 21, 2023

i was looking on more code

to open a menu it force me to provide an MenuProvider

NetworkHooks.openScreen((ServerPlayer) pe, ghost, pos);

NetworkHooks.openScreen((ServerPlayer) pe, ghost);

i dont understand the capability thing
dispensers and chest still save the data as nbt tags also networkhooks only has 2 openscreen methods asking for the player an a MenuProvider Entity

where i can find a tutorial or code i can look at to make mi own code ?

jumm thanks you and

im currently stuck at this point

i made a custome gui i made an itemstack class whit the "implements MenuProvider" thing pointing to that gui but

- idont get how to read the inventory from the itemstack soo mi upper slots are just draw in the background but no funtionality

i dont find other items inside vainilla minecraft implementhing the capabilityt thing soo i letthing eclipse to fill the gap, no succes here

	
    //this part of here 
    
	//this one created by eclipse
    public RegistryObject<MenuType<menu9>> getCapability(Capability<IItemHandler> itemHandlerCapability) {
        // TODO Auto-generated method stub
        return null;
    }
    
    //this one copied from the    GemInfusingStationBlockEntity example 
    //@Override
    public @NotNull <T> LazyOptional<T> getCapability(@NotNull Capability<T> cap, @Nullable Direction side) {
        if(cap == CapabilityItemHandler.ITEM_HANDLER_CAPABILITY) {
            return lazyItemHandler.cast();
        }
        
        //return super.getCapability(cap, side);
        return lazyItemHandler.cast();
    }

-also a idont know how or where the gui will return the changes isee the player inventory gets the blocks i change of place

soo i speculate the gui will return the inventory throught the "this.data = new ContainerData()" and gonna be recived inside the contructor of mi brief_case item class

the plan here is to directly pass the itemstack to the custome gui

way the inventory gets store inside the brefcase_item as nbt data with no entity/tylenetity in the middle of the operation

Opening a menu from an item is pretty much the same way as doing so for a block: call `NetworkHooks#openScreen` and pass in the associated inventory which should be attached as a capability to the stack.

You cannot just create the list on the item itself since that would apply globally to all instances of the item in the stack and be incorrectly synced.

ya i notice that but dont find an itemstack using the Capability<IItemHandler> to use as example also theres the problem of geting the new inventory from the gui in the container datapart

I mean...you can use any capability as an example for attaching to an itemstack. First one that comes to mind is the one on BucketItem. Then just swap out with the IItemHandler. If you don't own the item, you just use AttachCapabilitiesEvent.

SlotItemHandler? Other than that, pretty much nothing changes.
