Remove Tag from Item Upon Pickup?

[hoary hull]

I want to remove the 'c:hidden_from_recipe_viewers' tag (that hides stacks from EMI) from an item after it's obtained. Is there a way to do that?

I've tried:

    ServerEvents.tags('item', event => {
        event.remove('c:hidden_from_recipe_viewers', 'rediscovered:cherry_chair')
    })
})```
But it doesn't seem to work...

Tags are defined in server loading. Maybe you'd need to look for some method to dynamically adjust EMI.

Yes, I've just realised you would still need to restart a world to see the newly discovered items

But is there a way to remove tags using itemEvents still?

I'm just a noob in coding...

No. Although you could trigger a reload command there and update the tags, I don't recommend doing that.

So there's no way to do what I want to do..? 😭

It might depend on how EMI works. I haven't read its code so I couldn't say anything certain. But if you want it desperately, there's a method.

put this in startup script

global.server_pData = null

This in server script

ServerEvents.tags('item', event => {
    const pData = global.server_pData
    if(!pData) return;
    const toShowInEMI = pData.getCompound("toShow")
    toShowInEMI.allKeys.toArray().forEach(item => event.remove('c:hidden_from_recipe_viewers', item))
})

const itemsToShowAfterPickUp = ['rediscovered:cherry_chair',]
PlayerEvents.inventoryChanged(itemsToShowAfterPickUp, event => {
    const {item:{id}, server} = event
    const pData = event.server.persistentData
    const toShowInEMI = pData.getCompound("toShow")
    const shown = toShowInEMI.allKeys.toArray().includes(id)
    if(shown) return;
    toShowInEMI.putBoolean(event.item.id, true)
    pData.put("toShow", toShowInEMI)
    global.server_pData = pData
    server.reloadResources([])
})

Note that it causes server reload after player picking up the item, and thus it will have a lag

how bad the lag would be basically depends on how many mods/scripts you have

You can also do this with AStages since it allows you to hide and unhide items in EMI when obtaining the stage.
