[FossilOG]

Skript Version (do not put latest): Skript 2.4-beta5 (btw Its a custom version but Its just a tiny changes that wont affect the skript)
Skript Author: Bensku
Minecraft Version: 1.14.4

function actionbar(p: player):
    set {_uuid} to uuid of {_p}
    send actionbar "&c%{%{_uuid}%::health}%/%{%{_uuid}%::maxhealth}%❤    &a%{%{_uuid}%::defense}%❈ Defense" to {_p}

on damage:
    if attacker isn't player:
        set {_damage} to damage
        # this part is when you get hurt and you take damage and it's in sync with the your players health and
        # actionbar health for example if your player health is 8.5 hearts its going to to be like 85/100❤ or 8.2 hearts its going to be 82/100❤
        if {%{_uuid}%::health} is less than or equal to 100:
            remove {_damage} from {%{uuid}%::health}
            remove {_damage} from player's health
            bind hologram "&c-%{_damage}*2%" to victim for 1 seconds offset by 0, 1.5, 1
        if {%{_uuid}%::health} is greater than or equal to 101:
            remove {_damage} from {%{uuid}%::health}
            # this part below makes sure that he doesn't get hurt until his actionbar health is below 100 or equal to it
            # although I dont know how to do this part
            set %player's health% to 10
            bind hologram "&c-%{_damage}*2%" to victim for 1 seconds offset by 0, 1.5, 1

My "on damage:" part isn;t working everytime I take damage the actionbar health doesn't sync with the player health please help me ;(

if attacker isn't player: <- Is that correct?

Yes, cause they can die to fall damage and mobs

Yes, cause they can die to fall damage and mobs

It isn't correct, there is no player in a damage event, only victim (and possibly attacker)
