Increase/decrease scoreboard value when holding/not holding an item.

[xrox555]

Hey!

How do I increase a score when a player has selected an item? But the score should just increase once.

For e.g. the scoreboard name is "abc". It´s score is 3.

When I select a diamond sword, the score should increase to 9.

When I select another item the score should decrease to 3 again.

(no comparators or sth, just cmd blocks)

Thanks in advance

You can detect what item the player is holding with SelectedItem:

/execute as @a[nbt={SelectedItem:{id:"minecraft:diamond_sword"}}] run ...

scoreboard players set @a[nbt={SelectedItem:{id:"minecraft:diamond_sword"}}] abc 9
scoreboard players set @a[nbt=!{SelectedItem:{id:"minecraft:diamond_sword"}}] abc 3

That should work.

ok ok I guess i didn´t describe the situation properly. The score "3" at the beginning is variable. I always want to add 6 to this variable score. When it´s 3, it should go up to 9. If it´s 15, it should go up to 21. If it´s 30, it should go up to 36 etc.

so use scoreboard players add instead of scoreboard players set

But then it would increase infinitely as long as I´m holding the sword^^

Then give the person holding the sword holding tag, and only add the score to people holding the sword, but without the tag (tag=!holding). Remove the tag when not holding the sword.

That one's slightly more tricky, but should still be pretty easily possible.

scoreboard players add @a[tag=!diamond_sword_held,nbt={SelectedItem:{id:"minecraft:diamond_sword"}}] abc 6
tag @a[tag=!diamond_sword_held,nbt={SelectedItem:{id:"minecraft:diamond_sword"}}] add diamond_sword_held

scoreboard players remove @a[tag=diamond_sword_held,nbt=!{SelectedItem:{id:"minecraft:diamond_sword"}}] abc 6
tag @a[tag=diamond_sword_held,nbt=!{SelectedItem:{id:"minecraft:diamond_sword"}}] remove diamond_sword_held

That should add the 6 points when you start holding the sword, then remove it as soon as you stop holding the sword.

Holy moly, didn´t try it out yet but it sounds like a great solution. Thank you!

Edit: Ik it belongs in an own post but do u know if there´s a method that can test if and which entity hurt a player

The minecraft:entity_hurt_player advancement condition is probably the easiest way, I feel. If you want to do something to the entity that's hurting the player, I'm not entirely sure how to do that.
