[echo nimbus]

why?

why not an item frame?

[lethal snow]

use https://mcstacker.net to generate give command spawn eggs

but I don’t understand the question

[hardy cairn]

i trimmed it down

ok

so

how would i spawn a entity with a tag and replace entitys position with a barrel

i really just need help with the barrel part

[echo nimbus]

use an item frame

[lethal snow]

As I said you can use mcstacker to create a give command which spawns a marker with tags, then you can detect that marker with execute at @e[type=marker,tag=…] run setblock …

[lethal snow]

why?

[echo nimbus]

https://minecraft.wiki/w/Item_Frame#Item_data

[lethal snow]

If you tell us what this is for then maybe there’s a better way

[echo nimbus]

cuz he/she/it just wants to place down a custom barrel

they don't actually need a entity

[hardy cairn]

it would make it more simple

but the problem is

what i tend to do with this

i need it so when that barrel is set there it will automatically open the barrel

and i need the barrel invis

[echo nimbus]

you can't with datapacks

[hardy cairn]

the barrel invis?

[echo nimbus]

that it automatically opens

[hardy cairn]

well

then how would i go about making some custom gui

[coarse zealot]

Custom Gui

    >>> The guide is too long for Discord, please follow [this link](https://datapackhub.gitbook.io/custom-barrel-gui/) to get to the Guide.

[lethal snow]

You have to have it on a block or a chest minecart

[rain geyser]

if you don't want it bound to a block, you need a floating chest minecart in their head

[hardy cairn]

ok then ill use the minecart method

how would i do this

[echo nimbus]

then you just need regular right click detection

[coarse zealot]

Rightclick Detection

    >>> There are multiple ways to detect right clicks using datapacks/commands, here is a quick rundown on each of them and their cons and pros! 

You can get more detailed instructions on how to use them using their corresponding /methods

Warped Fungus on a Stick (WFOAS)/Carrot on a Stick (COAS)

This method works by using an item.used scoreboard objective which triggers when using either of the two items and then running commands as/at players with a score of 1 or higher.

Pros:

• easy to pull off
• works in any world
• doesn't require additional entities

Cons:

• wfoas attracts striders/coas pigs and rabbit

Depends:

• detects up to 5 clicks/second when holding right click

Eye of Ender (EoE)

This method works by using an advancement to detect whenever a player uses an eye of ender and then executing code as/at them.

Pros:

• doesn't require additional entities
• doesn't attract mobs
• doesn't need to run every tick

Cons:

• slows player down when holding right click
• only works in worlds without strongholds (there are ways to work around this, although these are way less performant)

Depends:

• detects up to 20 clicks/second when holding right click
• bound to the player, not a specific location

Interaction Entities

This method works by using an advancement to check whether a player interacted with an interaction entity and then executing code

Pros:

• see "depends"
• can also detect left clicks

Cons:

• requires an additional entity

Depends:

• detects up to 5 clicks/second when holding right click
• bound to a specific location, not player
• can't be interacted through

[rain geyser]

no that would then still require 2 clicks

when do you want the player to be able to open the gui?

like when they hold a specific item?

or in a specific area?

[hardy cairn]

well that certainly is aproblem

i need strongholds

[rain geyser]

you need what?

[hardy cairn]

strongholds

[rain geyser]

what do strongholds have to do with this?

[hardy cairn]

Cons:

slows player down when holding right click
only works in worlds without strongholds (there are ways to work around this, although these are way less performant)

to right click detection

[rain geyser]

ah, you don't want rclick detection

[rain geyser]

most of the time

[rain geyser]

when do you want the gui to open?

[hardy cairn]

when they hold a pasific item

and left click

[rain geyser]

not possible (*)

[echo nimbus]

[lethal snow]

the only way to open a custom ui is to trick them into right clicking it

[hardy cairn]

hm

[rain geyser]

you always need an actual container that they open

[hardy cairn]

ok what are the available ways

[rain geyser]

and that can be a minecart or a block

[hardy cairn]

then

[rain geyser]

and you open these with rclick

either click on the block or on the minecart

the minecart can be moved since its an entity

[lethal snow]

what do you actually want to put in the custom ui?

[rain geyser]

so if you want do "add a gui to an item" you really just spawn the gui in a minecart in their face when they hold the item and with rclick they interact with the minecart

that also makes it so other players and projectiles can't hit you

[hardy cairn]

wait im dum

that cons if for eoe

so right click detection is fine

[rain geyser]

it doesn't help you in any way

[hardy cairn]

the only downside is that it attracts stuff

[lethal snow]

you can’t open a ui with just right click detection

you need to make them legitimately right click on a container block or a chest minecart

[hardy cairn]

so what is possible

[lethal snow]

.

[hardy cairn]

a trading menu

thingy

[echo nimbus]

if it works for a wandering trader use that instead

[hardy cairn]

the wandering trader gui?

well

[lethal snow]

you want it custom right?

[hardy cairn]

its a player trading

[lethal snow]

so you can trade with other players and stuff

[hardy cairn]

yes

[hardy cairn]

this

[lethal snow]

it might be easier to like

just have a chat based ui

[hardy cairn]

what ever is easier for my smooth brain

[lethal snow]

or have it in a specific block like a “trading block” or something idk

[rain geyser]

custom gui is not easy and a minecart make it more complicated

a chat based gui is quite easy

but limited to text

as the interactable elements

[hardy cairn]

how would they trade there items via text?

[rain geyser]

like trade mainhand item

put item to trade in mainhand - run the chat based gui - select player to trade - wait for them to accept

or something like that

[hardy cairn]

okie

how would that be set up code wise

[rain geyser]

a bunch of tellraws and triggers

but how exactly depends on what you wanna do

[hardy cairn]

chat based

item mainhand is easier

so that

[rain geyser]

how do you then want to initiate the trade?

via command? is that fine?

it would be a /trigger <...> command

[hardy cairn]

/trigger placeholdertrade

[rain geyser]

then you need to add that objective with the criteria trigger

and enable that for all players

iirc you can do that every tick for @a without major sideeffects

[hardy cairn]

ye

[rain geyser]

and react to that being 1

because a /trigger without a number sets it to 1

or increases by 1? comes out to the same

[hardy cairn]

how would i get it

to

target a player

[rain geyser]

you probably need to give each player an id

and then display all of them

[hardy cairn]

how would i do this

[rain geyser]

with a trigger command as a click event

giving them a unique id?

or what exactly?

[hardy cairn]

how would i do the code cause i honestly dont know how i would do it

[rain geyser]

giving a unique id

• initiate a global score once
• any time a new player joins, set their id to the global score
• then increase the global score

u got macros right? if not this is very annoying

[hardy cairn]

i dont have one nor do i know what a macro is

[rain geyser]

what version are you in?

[hardy cairn]

1.20.4

[rain geyser]

k

u can use macros so all good

displaying all players, the easy way

• execute as all players
  • send a tellraw to the player who ran the command with their name and a /trigger click event that triggers to their score (maybe add some offset here if needed)

then the player who ran the command can just click on them and their triggered score corresponds to the player

[hardy cairn]

ok know i get it

[hardy cairn]

hello?

[hardy cairn]

@rain geyser

i have done it

i just need help with the macro

that prints off everybodys name in chat that is in the world/server

i did the click event

[rain geyser]

macros can run commands while replacing parts of the command
to run a macro with a scoreboard value, you do something like this

execute store result storage a: a.score int 1 run scoreboard players get @s id
function some:macro/function with storage a: a

$say THIS SHOULD BE THE TELLRAW COMMAND WITH /trigger gui_trigger_score set $(score)

this would print the say command with the score where $(score) is

you can use that to build yyour tellraw

[hardy cairn]

what is the score about?

is it the id?

also this confuses me

what does it do

[hardy cairn]

hello?

[uneven dove]

Hello, can you tell me briefly what the discussion was about?

[hardy cairn]

one sec

ok

im back

basically im trying to create a text based trading system

you trade whatever is in your mainhand

[uneven dove]

What have you already done?

[hardy cairn]

my ideas

like thinking

of them

[uneven dove]

They helped you here, I asked about it. what is already in the datapack?

[hardy cairn]

ok

so what ive done so far

is

trade.mcfunction: ```
tellraw @a {"text": "[Server] Trade Started", "color": "#ca6eff"}
tellraw @s {"text": "[Player Selector]", "clickEvent": {"action": "run_command","value": "/function duckie:test"}}
scoreboard players set @s trade 0
playsound minecraft:block.note_block.bell player @s ~ ~ ~ 500

test.mcfunction: tellraw @s {"selector":"@a"} playsound minecraft:block.note_block.harp player @a ~ ~ ~ 500
