Can you prevent hopper output on a specified block entity? | latcord | Page 1

#

Is there any way to prevent hopper output on a block entity with kubejs? Hypothetically like preventing a hopper from pulling from minecraft:barrel but everything else would work normally

Figured id ask if its possible

I can also be okay with preventing placing hoppers next to the block, and the block vise versa

try this js BlockEvents.rightClicked(event => { const {block,player,server,block: {id},player: {offHandItem,mainHandItem}} = event if (offHandItem.id != "minecraft:hopper" || offHandItem.id != "minecraft:barrel" || mainHandItem.id != "minecraft:hopper" || mainHandItem.id != "minecraft:barrel") return if (id == "minecraft:hopper" || id == "minecraft:barrel") { event.cancel() player.tell(`You can't place that here.`) } })

no errors but its not working for some reason

slow rose Oct 27, 2023, 12:27 AM

#

ah

#

sec

slow rose Oct 27, 2023, 12:36 AM

#

plush merlin no errors but its not working for some reason

so this version works ```js
BlockEvents.rightClicked(event => {
const { block, player, server, block: { id }, player: { offHandItem, mainHandItem } } = event

if (id == "minecraft:hopper" || id == "minecraft:barrel") {
    if (mainHandItem.id == 'minecraft:barrel' || offHandItem.id == 'minecraft:barrel'){
    player.tell(`You can't place that here.`)
    event.cancel()
    }else if (mainHandItem.id == 'minecraft:hopper' || offHandItem.id == 'minecraft:hopper'){
        player.tell(`You can't place that here.`)
        event.cancel()
        }
}

})```

#

however ive noticed a bit of an issue here

#

i doesnt matter if we block them from being placed on each other since we can place them on other blocks to achieve the same outcome

#

hmm

unique aspen Oct 27, 2023, 12:37 AM

#

placed maybe better

slow rose Oct 27, 2023, 12:37 AM

#

placed doesnt detect the block youre placing on

#

tho in the end if you place them on grass and place the barrel down next to the hopper itll still work

#

i wonder if theres a way to break the hopper if its by a barrel

#

mango youre the expert here how do we do it

unique aspen Oct 27, 2023, 12:42 AM

#

simply like ```js
BlockEvents.placed("minecraft:hopper", (event) => {
const { block, player } = event;

if (block.up.id === "minecraft:barrel") {
player.tell(You can't place that here.);
event.cancel();
}
})
BlockEvents.placed("minecraft:barrel", (event) => {
const { block, player } = event;

if (block.down.id === "minecraft:hopper") {
player.tell(You can't place that here.);
event.cancel();
}
});

slow rose Oct 27, 2023, 12:43 AM

#

block.up?

#

is that what detects the block placed on?

slow rose Oct 27, 2023, 12:44 AM

unique aspen simply like ```js BlockEvents.placed("minecraft:hopper", (event) => { const { ...

slow rose is that what detects the block placed on?

This will return the block above it when it was placed

plush merlin Oct 27, 2023, 12:46 AM

#

Thats perfect for what i need it for! thank you!

slow rose Oct 27, 2023, 12:56 AM

#

what about side to side

#

block right click is better imo

#

though we're still missing the point

#

this is with both of our scripts right now

#

blobbongoree

plush merlin Oct 27, 2023, 12:59 AM

#

I mainly just dont want to be able to take things out of it with a hopper, so it works for my use case

slow rose Oct 27, 2023, 12:59 AM

#

does it now?

#

worry

#

not really sure if its possible tbh

plush merlin Oct 27, 2023, 1:00 AM

#

Its working for me?

slow rose Oct 27, 2023, 1:00 AM

#

youd have to stop the block from ticking if its by the barrel

#

yeah but did you see the video?

#

both of our scripts are pointless from preventing players from doing this

#

but hey i mean its up to you if youre fine with it

plush merlin Oct 27, 2023, 1:02 AM

#

https://gyazo.com/a0579c0884456f8451288ce3e5889b28 works for me?

slow rose Oct 27, 2023, 1:02 AM

#

oh

#

im just dumb and didnt try out mangos script

#

fair enough, you win this round

#

good job mango

#

but wait

#

what about blocks that place blocks?

#

or pistons for that matter?

plush merlin Oct 27, 2023, 1:03 AM

#

Pistons cant move block entities

slow rose Oct 27, 2023, 1:03 AM

#

hmm i see

#

i guess that would work then

plush merlin Oct 27, 2023, 1:04 AM

#

Not too worried about someone trying to use a deployer to place a block

slow rose Oct 27, 2023, 1:04 AM

#

you dont care about that?

plush merlin Oct 27, 2023, 1:04 AM

#

I dont think it will be done

slow rose Oct 27, 2023, 1:05 AM

#

hmmm

#

maybe

#

well anyways

slow rose if youre satisfied

Hold on before i close it can i ask one more quick question, i want to replace minecraft:barrel now with a const but it doesnt seem to work properly

, it works once for the "up" but not the "down"

const hopperblocked = [
    'minecraft:barrel',
    'minecraft:chest'
    // placeholders
]

BlockEvents.placed("minecraft:hopper", (event) => {
    const { block, player } = event;
    
    if (block.up.id === hopperblocked) {
      player.tell(`You can't place that here.`);
      event.cancel();
    }
  })
  BlockEvents.placed(hopperblocked, (event) => {
    const { block, player } = event;
  
    if (block.down.id === "minecraft:hopper") {
      player.tell(`You can't place that here.`);
      event.cancel();
    }
  });

did I do something wrong?
// js noob here

slow rose Oct 27, 2023, 1:10 AM

hopperblocked returns an array

plush merlin Oct 27, 2023, 1:15 AM

#

slow rose hopperblocked returns an array

?

slow rose Oct 27, 2023, 1:19 AM

#

plush merlin ?

const block = [
    'minecraft:barrel',
    'minecraft:chest'
]
function hopperblocks() {
    for (let i = 0; i < block.length; i++ ) {
        return block
    }
}
BlockEvents.rightClicked(hopperblocks(),event => {
    const { block, player, server, block: { id }, player: { offHandItem, mainHandItem } } = event
    player.tell('test')
})```

#

so itd be ```js
const block = [
'minecraft:barrel',
'minecraft:chest'
]
function hopperblocks() {
for (let i = 0; i < block.length; i++ ) {
return block
}
}
BlockEvents.placed("minecraft:hopper", (event) => {
const { block, player } = event;

if (block.up.id === hopperblocks()) {
  player.tell(`You can't place that here.`);
  event.cancel();
}

})
BlockEvents.placed(hopperblocks(), (event) => {
const { block, player } = event;

if (block.down.id === "minecraft:hopper") {
  player.tell(`You can't place that here.`);
  event.cancel();
}

});```

#

woops there fixed it

plush merlin Oct 27, 2023, 1:25 AM

#

Doesnt work for some reason, no error

slow rose Oct 27, 2023, 1:25 AM

#

oh hmm

#

sec

#

weird that placing the barrel on the hopper is prevented but not the hopper under the barrel

plush merlin Oct 27, 2023, 1:28 AM

#

In fact it seems to break the script altogether, once one is placed below, you can place ones above

slow rose Oct 27, 2023, 1:28 AM

#

oh i know whats going on here

#

well it doesnt break the script its just we need to do it differently, im working on it sec

wait that one doesnt detect chests despair gimme min

#

@plush merlin this one works ```js
const hopperblocked = [
'minecraft:barrel',
'minecraft:chest'
]
ServerEvents.tags('block', event => { event.add("kubejs:hopperblocked", hopperblocked) })

BlockEvents.placed((event) => {
const { block, player } = event;
if (block.id == 'minecraft:hopper'){
if (block.up.hasTag('kubejs:hopperblocked')) {
player.tell(You can't place that here.);
event.cancel();
}}else if (block.hasTag('kubejs:hopperblocked')){
if (block.down.id === "minecraft:hopper") {
player.tell(You can't place that here.);
event.cancel();
}
}
})``` just make sure to do /reload to reload the tag event
