Subtracting & checking attribute numbers

[RusticcRen (rustic)]

Hi, I am making a mining system where a rock’s health is set via attributes. How do I subtract from the attribute value and check if its <= 0?

Hitbox.Touched:Connect(function(Mined : BasePart)
	if Debounce and Mined:HasTag("Mineable") and not MiningEvent then
		MiningEvent = true
		HitSound:Play()
		
		Mined:SetAttribute("MineableHealth", Mined:GetAttribute("MineableHealth" - Damage))
		Mined.Size = Vector3.new(Mined.Size.X / 1.2, Mined.Size.Y / 1.2, Mined.Size.Y / 1.2)
		
		if Mined:GetAttribute("MineableHealth" <= 0) then
			Mined:Destroy()
		end
		
		task.wait(Cooldown)
		MiningEvent = false
	end
end)

Mined:SetAttribute("MineableHealth", Mined:GetAttribute("MineableHealth" - Damage))

You should have the Damage subtraction outside the GetAtrribute like this:

Mined:SetAttribute("MineableHealth", Mined:GetAttribute("MineableHealth") - Damage)

Do subtraction operation separately before setting the new attribute value, use a variable to check if the health is less than or equal to 0.

If you need me to edit the code lmk.
