How do I make it to where if this entity exists, the script ends or returns?

[spark furnace]

Hi, I have a simple script here, but for whatever reason. I just can't figure out how to return or end the script if an entity exists.

                for (const entity of world.getDimension("overworld").getEntities({type: 'chaotic:multi'})) {
                    const multiType = entity.getDynamicProperty('multiType')
                    if (multiType == 'generic'){
                        const x = entity.location.x
                        const y = entity.location.y + 1
                        const z = entity.location.z
                        const items = world.getDimension("overworld").getEntities({tags:["item"],location:{x:x,y:y,z:z},maxDistance:1})
                        const random = Math.floor(Math.random() * (1 - 1 + 1)) + 1
                        if (random == 1){
                            world.structureManager.place("chaotic:itemPotionBomb",world.getDimension("overworld"),{x:x,y:y,z:z})
                        }
                    }
                }

I'm somewhat new to scripting, so lmk what I'm supposed to do

I want to check for if item exists, then return. However I have no idea how to do that

[untold pagoda]

detect item then fire return

[spark furnace]

I'm not really sure what you mean by that

[untold pagoda]

return;
its built-in callback or function

are you having issues with detecting item?

or returning part?

[spark furnace]

The part on firing return

I have the item detected I just don't know how to get after it being detected, if its successful it fires a return

[untold pagoda]

if you want to detect item then stop script from going onwards js do return;

[spark furnace]

I need to have it to where if it succeeds it returns, it wont always have an item.

Say it doesen't have an item. I want it to not return

[untold pagoda]

assign found items to variable then check if ur particular item is there

if it is then return

if its not dont return

casual if statement

[spark furnace]

The main issue is that they use a tag, as once they are picked up they lose the tag and act as a normal item. We are only checking for items with a tag. I need to make an if statement with this and I don't know how.

[untold pagoda]

items.forEach(element => {
    let comp = element.getComponent("item")
    if (comp.itemStack.typeId == "<item_identifier>") {
        world.sendMessage("item found!")
    }
    else {
       world.sendMessage("item not found :<")
    }
})```

[spark furnace]

I'm trying to get the item entity tag. As in from the /tag command

[untold pagoda]

with tag:

items.forEach(element => {
    if (element.hasTag("<tag_here>")) {
        world.sendMessage("item found!")
    }
    else {
       world.sendMessage("item not found :<")
    }
})```

[spark furnace]

Ooh okay

[spark furnace]

It seems none of the code within the object will execute, as no item exists to begin with. As the item spawns from the code we are trying to stop running if an item is spawned.

At least thats from what I'm seeing. As not even console.warn() will go through from the object.

The code I'm using here:

const items = world.getDimension('overworld').getEntities({location: {x:x,y:y,z:z}, type:"minecraft:item"})
items.forEach(element => {
    if (element.hasTag("item")) {
        console.warn('Failed')
    } else {
        console.warn('Sucess')
        const random = Math.floor(Math.random() * (1 - 1 + 1)) + 1
        if (random == 1){
            world.structureManager.place("chaotic:itemPotionBomb",world.getDimension("overworld"),{x:x,y:y,z:z})
        } 
    }}

I'm spawning it via a structureblock to have a tag attached to it, as tags get removed once picked up. But are added when spawned w/ it

[untold pagoda]

what is running that script? any event? and failed should be success

[spark furnace]

For now its just on system interval as its normally delayed to work every 1200 ticks, or 1 minute.

I have it set faster for working on it though

[untold pagoda]

um try using entitySpawn or load event

it would be much more optimized

and easier to detect item

[spark furnace]

Well I can do that but the issue still is none of the object is running

Which includes the console.warn

Probably because we're only running if their is an entity. then running the check.

[untold pagoda]

put world.sendMessage(${element.typeId}) inside forEach

for debug

[spark furnace]

Alr

"element is not defined" gets returned everywhere. Because the item doesn't exist yet

[untold pagoda]

yeah i got it, what happens if the item does exist

[spark furnace]

Then it works

Another thing is I had maxDistance:1 setup. This I don't

If I set that up it'd likely not work again either, unless it meets all requirements

[untold pagoda]

yea cause you set maxDistance to 1

[untold pagoda]

and it should work so it does work

[spark furnace]

The item is supposed to only spawn if the item isn't already spawned

And the moment somebody picks it up it can spawn again

Hence the maxDistance 1 is being used

(It's also spawned with a tag because a special effect is added to it)
