How to update a player's max health?

[Jetug]

I'm modifying the player's max health attribute but it only updates when the player gets damage

    private static void addMaxHealth(Player player, double value) {
        player.getAttribute(Attributes.MAX_HEALTH)
                .addPermanentModifier(new AttributeModifier("health", value, AttributeModifier.Operation.ADDITION));
    }

The code works when I try it. From where are you calling it?

From finishUsingItem() in my item class

   	public ItemStack finishUsingItem(ItemStack stack, Level level, LivingEntity entity) {
		if (entity instanceof Player player)
			setAddMaxHealth(player, -10)
        return super.finishUsingItem(stack, level, entity);
    }

The code works fine only when the value is positive

If you call setHealth() after you changed the attribute it should update immediately, something like this:

			player.setHealth(Math.min(player.getMaxHealth(), player.getHealth()));
