fixing backpack

[humble sparrow]

@echo swallow

[echo swallow]

so what isn't working?

[humble sparrow]

when i switch from a backpack to another directly it saves items in the other backopack

so i was thinking what can i do to make it respawn the entity when switching from backpack to another

[echo swallow]

how does this “backpack system” work?

so you want the backpack entity to despawn if the player isn't holding a backpack, but it doesn't if you hold another?

[humble sparrow]

backpack entity needs to despawn if backpack isnt the same

[echo swallow]

ok, how do you tell backpack items apart?

[humble sparrow]

wdym

i used a JSON.stringify(backpackItems) where backpack items are a list of items, amount,slot

[echo swallow]

if you have backpack item number 1 and backpack item number 2 in your hotbar, how do you know which one are you holding to spawn the correct entity?

[humble sparrow]

backpack item? you mean backpack item in sense of hotbar backpack?

[echo swallow]

didn't you say you get the player's held item?

[humble sparrow]

it looks if player is holding a backpack then it spawns the entity then it checks the lore

then with the lore it gets the items to set in the entity

[echo swallow]

does it work like this:

• if heldItem is backpack -> spawn entity
• get lore, convert it to items, give it to the entity
• tp the entity and update the lore
• if heldItem is not backpack -> despawn entity

[humble sparrow]

That’s how it works for now

If I switch from backpack 1 to backpack 2 the held item id is still btm:backpack

[echo swallow]

ok you said a player can have multiple back packs right? how do you know which lore to use?

[echo swallow]

how about this: why not using item dynamic properties to store the items inside the backpack item itself?

[humble sparrow]

It gets the lore of the backpack then it gives the dynamic prop that is named as the lore of the item, then it takes the items from propriety then it loads it into entity

[humble sparrow]

I am stupid you re right

Wait can I set dynamic proprieties to items?

[echo swallow]

this way you don't have to match the item with the correct player anymore, and you can give the backpack to other players and they can still use it

[echo swallow]

yes, but i think it's still beta api

nope, it's released, it is stable now

[echo swallow]

but make sure to set the item back to the player, otherwise your changes are going to get lost

[humble sparrow]

so i have to set aganin and again backpack to player?

[humble sparrow]

it doesnt work

[humble sparrow]

the problem is not that, the problem is that when you change item i dont know why it saves them in the other bakpack

[humble sparrow]

finally i fixed it

i just needed to check if player has changed item and if it has then it blocks the save funcion

so it wont save it in another backpack

[echo swallow]

glad it works

[odd hull]

did you get this to work?

[humble sparrow]

wait lemme chech my addon

[odd hull]

thats a lot xD

[humble sparrow]

also an entoty

[odd hull]

i was going through your code, basically it spawns the entity in front of the player right?

or how exactly is it done?

[humble sparrow]

yeah becouse this works in multiplayer, and saves multiple backpack

[odd hull]

what happens once the player is off the inventory screen?

[humble sparrow]

yeah so you can open it easily, its an invisible entity and its little and spawns in player head so other players cant open your backpack

[odd hull]

can i see your entity behavior?

[humble sparrow]

nothing it just spawns the entity when you are holding the backpack and it gets the backpack lore so it can get the id of the backpack and give the items

[humble sparrow]

this backpack has an huge problem, it doesnt save items enchantments

[odd hull]

oh i understtand now

[odd hull]

oh darn

because of the limits to the lore right?

[humble sparrow]

yeah

but i was creating something to hold all items

[odd hull]

hmmm

okay if you figure it out, let me know

[humble sparrow]

thats the item db im working on'

[odd hull]

i love the notes 🙂

[humble sparrow]

this can save, and load items

[humble sparrow]

i was thinking of post it on resurces

notes are made by chatgpt btw

[odd hull]

oh are they?

well thats good, easy to read the functions

[humble sparrow]

yeah i wasnt gonna do it for all functions

[odd hull]

so is this ready? Or are you still working on it?

[humble sparrow]

this can store up to 99999 items and you can load/save items everywhere you are, it also saves item as an itemstack object so you wont loose anything

[humble sparrow]

just need to test the spawn thing at the start

[odd hull]

alr sounds good

[humble sparrow]

and testing if i can add more slot to entity

[odd hull]

More!

???

[humble sparrow]

you think 99999 is ok? i was thinking if someone needs to do this on a server

[odd hull]

oh i see

[humble sparrow]

this can hold up to 3333 backpacks that are 30 slots each

33thousand backpacks works

[humble sparrow]

finished it it works fine for addItem and getItem #1252014916496527380

the other ones i think they work just as fine

[mental bolt]

Nah what a bad backpack system...

[humble sparrow]

what you suggest

[mental bolt]

You dont save the actual item, just the typeId and amount, you lose every other property/component lol

[humble sparrow]

yeah thats why i said that i was working to save the item as an itemstack and not as a dynamic property

and i did the store system

[mental bolt]

I see

thats good then

an entity item db

that can save the actual item

[humble sparrow]

yeah and it has 999999 slots so you wont get storage size issues

[azure osprey]

?

Wth

[sharp stirrup]

this does works? and saves with echnats lore NBT data?

[humble sparrow]

That script is very old...

It works in the latest version
and yes it saves all with NBT you can even save enchanted items in a shulkerbox in this database
#1252014916496527380 https://github.com/Carchi777/QUICK-ITEM-DATABASE

[sharp stirrup]

in 1.21.60 ?

[sharp stirrup]

but i want when entity gets hit or dies drop own spawning egg or item like backpack etc. and players spawns entity and inventory still inside an saves entity color nametag also i dont want save as name they can exploit this i want make ID save not nametag save

entity name is** lekoji:upgraded_shulker**

[humble sparrow]

it works in 1.20.60 but i meant In the last version of the database

[humble sparrow]

This is an item database not a backpack

[sharp stirrup]

i m suck at main.js

[humble sparrow]

What?

[sharp stirrup]

bacily on entity killed, saves data stored at a item if player places again an inventory , nametag , color will back

it is like shulker box but is a entity

but large stroge

i will back in 20 mins wait

[humble sparrow]

Yeah you can use that database to store the backpack items when you kill the backpack or spawn it

[sharp stirrup]

but how i can save inside in item?

[humble sparrow]

you cant save inside an item

but you can link it to an item

[sharp stirrup]

i mean this

threes a add-on did

backpack entity system saves inside item

[humble sparrow]

you can set an unique ID in the backpack (item) DynamicProperty, and in the database set a key that has the same ID as the backpack (item)

then if you want to get the backpack's items you just get the ID from the dynamic property and get the linked key

[sharp stirrup]

how i can code ? i m bad at script api

[humble sparrow]

Visual Studio Code is the best option

[sharp stirrup]

i dont have any time to use pc and visual studio doesnt downloading

[humble sparrow]

i donk know then how you can do it

you can use bridge web app https://editor.bridge-core.app/
