How can i make this work?

[thin robin]

// priority: 1

ServerEvents.tags("item", event => {
    const originalTag = "forge:dusts/niter";
    const tag = "#" + originalTag;
    const replacement = "thermal:niter_dust";
    var tags = [];

    Ingredient.of(tag).itemIds.forEach(tagItem => {
        var tagItemTags = Item.of(tagItem).getTags().toArray();

        tagItemTags.forEach(tagId => {
            var tagString = tagId.toString();
            var tag = tagString.substring(tagString.indexOf('/') + 2, tagString.indexOf(']'));

            tags.push(tag);
        });
    });
    event.get(originalTag).removeAll();
    tags.forEach(itag => {
        event.add(itag, replacement);
    });
});

what is this even supposed to do

[thin robin]

for every item in #forge:dusts/niter that isn't thermal:niter_dust, gather all the tags, remove the tags from all of them, and apply them to thermal:niter_dust

Not possible atleast not with to startups

[thin robin]

it is

    const originalTag = "forge:dusts/wood";
    const tag = "#" + originalTag;
    const replacement = "thermal:sawdust";
    var tags = [];
``` it works with this

[foggy cave]

You can't get Tags during the Tag event

Tags aren't initialized yet

What even is the error

[thin robin]

[20:47:29] [INFO] OreDict.js#20: forge:dusts
[20:47:29] [INFO] OreDict.js#20: forge:dusts/wood
[20:47:29] [INFO] OreDict.js#20: forge:sawdust
``` i quite literally have

[peak pendant]

pretty sure the KJS tag even runs last

[thin robin]

and the idea is to unify item tags

2 different items that represent the same thing can have different tags and if you unify them some recipes might be broken because the recipe requires a tag that isn't available in the unified version of the item

[foggy cave]

Could be, i think the was a time where this didn't work could be that this changed

Don't assume anyone knows what you are talking about, be specific.

Provide screenshots or video of the issue if possible.

Provide the log.

[foggy cave]

Basically asking what's the Error Happening/ what you See Happening

[thin robin]

thermal:niter_dust is supposed to have all those 3 tags, and immersiveengineering:dust_saltpeter is supposed to have none

[foggy cave]

Yeah that Happens because you're only looking for items that have the Tag niter but immersive doesn't have that so nothing is changed

[thin robin]

oh yeah i fixed it now

// priority: 1

ServerEvents.tags("item", event => {
    event.add("forge:dusts/niter", "immersiveengineering:dust_saltpeter");
    event.add("forge:dusts", "immersiveengineering:dust_saltpeter");
});

ServerEvents.tags("item", event => {
    const originalTag = "forge:dusts/niter";
    const tag = "#" + originalTag;
    const replacement = "thermal:niter_dust";
    var tags = [];

    Ingredient.of(tag).itemIds.forEach(tagItem => {
        var tagItemTags = Item.of(tagItem).getTags().toArray();

        tagItemTags.forEach(tagId => {
            var tagString = tagId.toString();
            var tag = tagString.substring(tagString.indexOf('/') + 2, tagString.indexOf(']'));

            tags.push(tag);
        });
    });

    tags.forEach(itag => {
        event.removeAll(itag);
        event.add(itag, replacement);
    });
});

ofc im gonna pack it all into a function

danke

it works now
