Outdated script help

[plush hull]

been working with an old script which seems to give me errors when i try to use it. I used stable scripts for the old and current version, so im a bit confused as to what changed

[plush hull]

It spams this error when an entity is below it

[dim vigil]

Use on interact

[plush hull]

I should specify what its supposed to do

The spawnegg is supposed to only work when used on the bottom of a block, else it just doesnt work at all and says "Invalid Position!"

What its doing now, is saying "Invalid position!" but still spawning the barnacle anyway

im probably gonna redo it completely

[sage perch]

have you tried replacing itemUse with playerInteractWithBlock

[plush hull]

im making a fresh new script right now

i need the experience

[sage perch]

well ig if you wanna do that, it might be better

[plush hull]

    system.run(() => {
        
    })
})```

[plush hull]

could you help me figure this out?

[sage perch]

sure

[plush hull]

thank you 🙏

[plush hull]

atm i have it set up so itll work since beforeEvents is read-only

system.run

[sage perch]

well if you're not using data.cancel then use afterEvents

[plush hull]

how do i make it stop a player from placing a spawn egg unless it's on a certain block face

[plush hull]

pretty sure i might be

i gotta make the player unable to place a spawn egg anywhere but the bottom of a block

[sage perch]

for that one you need to use the event playerInteractWithBlock

[plush hull]

i meant a specific spawn egg

xen:barnacle_spawn_egg

or valve:barnacle_spawn_egg

idk if i ever changed the identifier when moving it between addons

xen

[sage perch]

world.beforeEvents.playerInteractWithBlock.subscribe(data => {
  const block = data.block;
  const item = data.itemStack;
  const blockFace = data.blockFace;
  
  if (!data.isFirstEvent && item.typeId == "xen:barnacle_spawn_egg") return;
  if (blockFace != "Down") {
    data.cancel = true;
  };
});

[plush hull]

none of it is read-only?

[sage perch]

yep

[plush hull]

i see... data.itemStack represents items

[sage perch]

correct

[plush hull]

data.blockFace is obvious

and so is data.block

[sage perch]

data.player exists too just incase if you need it

[plush hull]

thank you

i may use that later

hmmm

!data.isFirstEvent

what does that mean?

i know it means "not" data.isFirstEvent, i meant what does data.isFirstEvent

[sage perch]

basically when a player is holding right click on a block, it technically interacts a lot of times at once so what firstEvent does is check if the player just interacted once

[plush hull]

ah

[sage perch]

otherwise it'll spawn 100 of them in 1 second

[plush hull]

LOL

that would be interesting for some later shenanigans

but not at the moment

[plush hull]

data.cancel cancels the event when the boolean is set to true

i see

what other things are there?

data.(..)

[plush hull]

i imagine there may be an entry in the wiki for it

[sage perch]

all of these exist

[plush hull]

oo

thanks

[sage perch]

https://jaylydev.github.io/scriptapi-docs/latest/classes/_minecraft_server.PlayerInteractWithBlockBeforeEvent.html

you can search up for other events in there and it should give you the stuff for it

[plush hull]

awesome

[plush hull]

tested it, doesnt work

it doesnt seem to cancel the event

[sage perch]

no errors?

[plush hull]

nope

world.beforeEvents.playerInteractWithBlock.subscribe(data => {
    const block = data.block
    const item = data.itemStack
    const blockFace = data.blockFace

    if (!data.isFirstEvent && item.typeId == "xen:barnacle_spawn_egg") return
    if (blockFace != "Down") {
        data.cancel == true
    }
})```

did i forget something?

[plush hull]

looks like i forgot something, but idk what i forgot

[plush hull]

something that looks odd is return being at the spawn egg thing

wouldnt return just stop it?

[sage perch]

OH

you're right. it's checking if the item is the spawn egg and if it is it will stop there

replace the == with !=

[plush hull]

still doesnt work

have you considered that beforeEvents is read-only?

what was the workaround to that

system.run i think

[sage perch]

that isn't the issue right now, the only problem is that the logic is some how wrong

so what the hell is happening 😭

not a single error

try this one

[plush hull]

i was thinking the same thing earlier

using if; else

oop

not if; else

if; then

i just didnt know how to do that in js

ITS WORKING

tysm 🙏

wlp

now

its time for the hard part

the tongue

and the mechanics of the tongue

[sage perch]

scary

[plush hull]

for this ill use properties

xen:tongue_length will determine the length of the tongue

we should probably start with that

[plush hull]

how would i detect the distance between an entity and the ground below it?

and use it as a variable

const tongueLength == ?

[sage perch]

const tongueLength = entity.isOnGround ? 0 : entity.location.y -entity.dimension.getTopmostBlock({x: entity.location.x, z: entity.location.z}).location.y

[plush hull]

thats complex

could you explain some of it to me

[sage perch]

yeah i know

[plush hull]

i think ive seen this before, wouldnt it detect the highest block at that x and z coordinate?

that would be "entity y position" - "highest block at entity's x and z coordinates" by the looks of it

the barnacle hangs from the ceiling

[sage perch]

it checks if entity is on ground, if true it will return 0, otherwise it will negate entity y location to the highest block in the world y

[plush hull]

barnacles hang from a block, meaning the tongue length would be way off to what the actual distance between the barnacle and the ground is

[sage perch]

which means?

[plush hull]

if the barnacle was in a cave that was 16 blocks in height, but the ceiling of that cave was at y 64 and the highest point at the barnacle's x and z coordinate was y 100, the tongueLength variable would be set to -36 (64 - 100 = -36) instead of the desired 16 (the distance between the barnacle and the ground below it)

it would set the tongue too long or too short

[sage perch]

right, I didn't think of that

[plush hull]

tongueLength == (equation to determine length) - 0.6

this allows me to make sure the tonguelength stays slightly above the ground

[sage perch]

does the tongue have a limit of blocks

[plush hull]

since the tongue will be adjustable as to change the length when it catches a mob, yes

the default limit is 128 blocks

[sage perch]

let tongueLength = 0;
for (let i = -1; i < 129; i++) {
  if (entity.dimension.getBlock({ x: entity.location.x, y: entity.location.y - (i + 1), z: entity.location.z}).typeId == "minecraft:air") continue;

  tongueLength = i;
}

[plush hull]

so i is a temporary variable by the looks of it

[sage perch]

now what this does is keep checking each block below it one by one untill it finds a block that isn't air

[plush hull]

and tonguelength = i

[plush hull]

i see

[sage perch]

tbh everyone uses i as a temporary variable

[plush hull]

fair

im not used to scripting but im learning

[plush hull]

(let i = -1; i < 129; i++)

what does this mean?

also cant you use <= 128?

or is that not possible there

[sage perch]

start from -1 and keep adding +1 untill you reach 128

[plush hull]

ah

oke

[sage perch]

true but same thing

[plush hull]

fair enough lol

imma test it rq

[sage perch]

i'll be suprised if it works

[plush hull]

we still havent made it actually define the tonguelength property

xen:tongue_length

is the property

[sage perch]

entity.setProperty('xen:tongue_length', tongueLength)

[plush hull]

thats..

actually really simple

[sage perch]

im terrible with entity stuff but ig this'll work

[plush hull]

i just encountered a bug with earlier code

if im not holding anything and i right click a block, it spams the hell out of the console with errors saying they cant read the typeId

[sage perch]

world.beforeEvents.playerInteractWithBlock.subscribe(data => {
  const block = data.block;
  const item = data.itemStack;
  const blockFace = data.blockFace;
  
  if (item && data.isFirstEvent && item?.typeId == "xen:barnacle_spawn_egg") {
    if (blockFace != "Down") {
      data.cancel = true;
    };
  };
});

[plush hull]

this doesnt seem to work

[plush hull]

oh yea this fixed it

sorry

thanks

[plush hull]

this still doesnt work however

i think its because its just wildly defining "entity", and not locking it to the barnacle entity

[sage perch]

where'd you put the setproperty thing in your code

[plush hull]

ive tried both inside and outside the tonguelength code

[sage perch]

send a screenshot of your code or smtg if you don't mind

[plush hull]

i think we forgot to define entity

[sage perch]

entity is defined, right?

[plush hull]

maybe if we set entity to xen:barnacle itll work?

[sage perch]

yep it should

[plush hull]

const entity = "xen:barnacle"

would that work?

i dont think it will because bridge doesnt seem to have any of that in its syntax

[sage perch]

not really, what that does is just define entity as a text

[plush hull]

ah

[sage perch]

system.runInterval(() => {
  const barnacles = world.getDimension("overworld").getEntities({ type: "xen:barnacle" });
  for (const entity of barnacles) {
    //put the code inside of here
  }
}, 10)

this'll do, just put the code you already have inside the place where I specified it

[plush hull]

got it

testing it now

[sage perch]

basically what it does is every 10 ticks (half a second) it will look for every single barnacle in the overworld and then it'll set it's property

note that it only works if the entity is in the overworld

not nether or end

[plush hull]

strange, now its spamming this error

[sage perch]

okay 128 is too much

wait

[plush hull]

could that be fixed by doing ("overworld","nether","end")?

[sage perch]

nvm

[sinful ether]

dimension.heightRange.min or max

[plush hull]

uh

?

[sage perch]

system.runInterval(() => {
  const barnacles = world.getDimension("overworld").getEntities({ type: "xen:barnacle" });
  for (const entity of barnacles) {
    let tongueLength = entity.isOnGround ? 0 : null;
    const maxHeight = entity.location.y - entity.dimension.heightRange.min;
    const ground = entity.dimension.getBlockFromRay(entity.location, { x: 0, y: -1, z: 0 }, { maxDistance: maxHeight })?.block;
    tongueLength = ground ? entity.location.y - ground.y : maxHeight;
    entity.setProperty("xen:tongue_length", tongueLength);
    }
  }
}, 10)

i forgot getBlockFromRay and heightRange existed 😞

[plush hull]

oop

[plush hull]

would entity.setProperty("xen:tongue_length", tongueLength - 0.7) work?

for the part that defines the property

[plush hull]

the tongue works now!!! however it spams this error

[plush hull]

also there were an incorrect number of brackets

system.runInterval(() => {
    const barnacles = world.getDimension("overworld").getEntities({ type: "xen:barnacle" });
    for (const entity of barnacles) {
        let tongueLength = entity.isOnGround ? 0 : null;
        const maxHeight = entity.location.y - entity.dimension.heightRange.min;
        const ground = entity.dimension.getBlockFromRay(entity.location, { x: 0, y: -1, z: 0 }, { maxDistance: maxHeight })?.block;
        tongueLength = ground ? entity.location.y - ground.y : maxHeight;
        entity.setProperty("xen:tongue_length", tongueLength);
    }
}, 10)```

fixed

entity.setProperty("xen:tongue_length", tongueLength - 0.6);

this is line it keeps saying is causing the error

(with and without the - 0.6)

system.runInterval(() => {
    const barnacles = world.getDimension("overworld").getEntities({ type: "xen:barnacle" });
    for (const entity of barnacles) {
        let tongueLength = entity.isOnGround ? 0 : null;
        const maxHeight = entity.location.y - entity.dimension.heightRange.min;
        const ground = entity.dimension.getBlockFromRay(entity.location, { x: 0, y: -1, z: 0 }, { maxDistance: maxHeight })?.block;
        tongueLength = ground ? entity.location.y - ground.y : maxHeight;
        entity.setProperty("xen:tongue_length", tongueLength - 0.6);
    }
}, 10)```

    for (const entity of barnacles) {

        entity.setProperty("xen:tongue_length", tongueLength - 0.6);
    }
}, 10)

give this a try

[plush hull]

so what was the error? everything points to the property's value going beyond what it's supposed to be, but visually the values were defining themselves just fine

it looked like it was adding to the value over and over again even when there was no barnacle

[sage perch]

oh yeah, did you remove the old code?

the one that had for (let i = -1.....

[plush hull]

yea

[plush hull]

this?

[sage perch]

yep

[plush hull]

let tongueLength = 0
for (let i = -1; i < 129; i++) {
    system.runInterval(() => {
        const barnacles = world.getDimension("overworld").getEntities({ type: "xen:barnacle" });
        for (const entity of barnacles) {
            let tongueLength = entity.isOnGround ? 0 : null;
            const maxHeight = entity.location.y - entity.dimension.heightRange.min;
            const ground = entity.dimension.getBlockFromRay(entity.location, { x: 0, y: -1, z: 0 }, { maxDistance: maxHeight })?.block;
            tongueLength = ground ? entity.location.y - ground.location.y : maxHeight;
            entity.setProperty("xen:tongue_length", tongueLength - 0.6);
        }
    }, 10)
}```

[sage perch]

so this is the code that you're using

[plush hull]

yep

it works but

its still giving me the error

[sage perch]

makes sense.

[sage perch]

system.runInterval(() => {
    const barnacles = world.getDimension("overworld").getEntities({ type: "xen:barnacle" });
    for (const entity of barnacles) {
        let tongueLength = entity.isOnGround ? 0 : null;
        const maxHeight = entity.location.y - entity.dimension.heightRange.min;
        const ground = entity.dimension.getBlockFromRay(entity.location, { x: 0, y: -1, z: 0 }, { maxDistance: maxHeight })?.block;
        tongueLength = ground ? entity.location.y - ground.location.y : maxHeight;
        entity.setProperty("xen:tongue_length", tongueLength - 0.6);
    }
}, 10)

get rid of all that code (except for the imports) and replace it with this

[plush hull]

everything?

including the spawn egg thing?

still the same error

lemme try something..

[astral tartan]

No Errors

No errors in [code](#1408178197215838269 message)

[sage perch]

no

[plush hull]

got it

the spawn egg thing is still there

still the same error again and again

i changed the range of the property and it's still doing it

[sage perch]

can you log ground.location.y, entity.location.y, and maxHeight?

[plush hull]

how?

WAIT

i have an idea

[sage perch]

world.sendMessage(`GroundY: ${ground.location.y}, EntityY: ${entity.location.y}, maxHeight: ${maxHeight}, tongueLength: ${tongueLength}`)

put it below the part where you setproperty

[plush hull]

oh

[sage perch]

oo go on

[plush hull]

ok

[plush hull]

i was thinking instead of properties we found a different way of client syncing the tongue's length

basically defining tongueLength like we are now, but instead of using properties to define it in the animation (which is causing the errors) we could try finding an alternative way to make a variable thats usable in molang

[sage perch]

the issue is still in the script tho, its returning a number so high so even if we did that it won't work

[plush hull]

fair

i dont see what in the world is making it set the value so high

i also dont understand how the hell the script techinically IS working fine, but somehow not at the same time??
|

wait a damn minute

gimme a second.

I FIGURED IT OUT

i feel so stupid

[sage perch]

what was it

[plush hull]

remember our earlier hassle with the barnacles still spawning after the egg was supposed to be limited to the bottom of a block?

i have it set up so barnacles fly up until they hit a ceiling

the barnacles were flying so high up that they unloaded yet stayed loaded at the same time

which was causing the overload

all we need now is a failsafe

so it doesnt happen again, in the case that a barnacle flies away like that

[sage perch]

check if value is higher than 400 and if it is kill the entity?

or just don't save the property

[plush hull]

maybe it could detect if it has air up to 5 blocks above it

and if it does, despawn the barnacle

if it has at least one non-air block up to 5 blocks above it, leave the barnacle alone

[sage perch]

system.runInterval(() => {
    const barnacles = world.getDimension("overworld").getEntities({ type: "xen:barnacle" });
    for (const entity of barnacles) {
        const blockAbove = entity.dimension.getBlockFromRay(entity.location, {x: 0, y: 1, z: 0}, {maxDistance: 5})?.block
        if (!blockAbove) entity.remove();
        let tongueLength = entity.isOnGround ? 0 : null;
        const maxHeight = entity.location.y - entity.dimension.heightRange.min;
        const ground = entity.dimension.getBlockFromRay(entity.location, { x: 0, y: -1, z: 0 }, { maxDistance: maxHeight })?.block;
        tongueLength = ground ? entity.location.y - ground.location.y : maxHeight;
        entity.setProperty("xen:tongue_length", tongueLength - 0.6);
    }
}, 10)

    }
}, 10)

[plush hull]

ITS WORKING

FULLY FUNCTIONALLL

YES

and now for the next part

grabbbiiiinnng

barnacles hang their tongues from their mouths, and whenever something touches them,(an item or a mob/player) the tongue's length snaps to the entity that it caught, and slowly pulls it up (1 block per second)

once the entity reaches the barnacle's mouth, it begins to chomp away at it

[sage perch]

test if there is an entity below the barnacles and then pull the entity upwards?

[plush hull]

id say select an area that is 0.8 blocks wide aligned with the barnacle's x and y position

then make the area's y length equal to the tongue length

sorry

back

if an entity come into contact with that area, the tongue's length snaps to the y position of the entity, lock the entity to the bottom of the tongue, and pulls the entity to the mouth (stopping the entity when the tongue's length reaches 1)

[sage perch]

can the entity being pulled escape mid-being pulled or no

[plush hull]

if the barnacle dies

otherwise they are stuck

[sage perch]

same thing for player?

[plush hull]

yep

[sage perch]

make a property called xen:pulling which holds boolean

if (entity.getProperty("xen:barnacle_is_pulling") == false) {
  const target = entity.dimension.getEntitiesFromRay(entity.location, {x: 0, y: -1, z: 0}, {maxDistance: entity.getProperty(tongueLength)}).entity;
  if (target) {
    entity.setProperty("xen:barnacle_is_pulling", true)
    const run1 = system.runInterval(() => {
      if (entity.getProperty("xen:tongue_length") == 1 || if !target) system.clearRun(run1);
        target.teleport(x: entity.location.x, y: target.location.y + 0.1, z: entity.location.z);
     }, 2)
  }
}

this should do the pulling

[plush hull]

i actually have a property set up already

xen:barnacle_is_pulling

[plush hull]

the script stopped working

the error seems to be the x:

and other coords

im confident this one would be good 👍

[plush hull]

oke

ill test it

good news and bad news

good news, the script works again

bad news, its not picking anything up

i noticed youre using the property tongueLength instead of the earlier set const tongueLength

maybe changing that would work?

[sage perch]

yeah ig that'll work

but thats not the reason you're not getting pulled

hmmmmmmmmmmmm

[plush hull]

maybe instead of teleporting it, it could set the velocity to push it towards the bottom of the tongue (after the tongue snaps to the entity's y position)

[sage perch]

the only reason I used teleport is to make sure the player doesn't run away

[plush hull]

teleport causes a snappy effect which makes players unable to look up and attack the barnacle

[sage perch]

yeah

applyknockback'll do then

[plush hull]

perfect

[sage perch]

its so late for me, I need to go to sleep, sorry mate

[plush hull]

before you go

[sage perch]

[plush hull]

tysm 🙏
