How do you cut down a tree with an axe after several hits?

I am planning on making a system where when you hit the tree with an axe, it disappears and you get wood. The script works for the most part, but the tree disappears after one hit.

Question: Is there any way that I could make it where you have to hit the tree with the axe multiple times?

The "Tree" model just has two parts called "Leaves" and "Trunk". I put a LocalScript in the axe tool. The script is listed below. Please let me know if you could help!

local player = game.Players.LocalPlayer
local mouse = player:GetMouse()
local tool = script.Parent
local active = true
local animation = tool.Animation
local wood = game.ReplicatedStorage.Resources.Wood

tool.Activated:Connect(function()
	local char = tool.Parent
	local humanoid = char.Humanoid

	local AnimationTrack = humanoid:LoadAnimation(animation)
	AnimationTrack:Play()
	
	local target = mouse.Target
	if target then
		if target.Name == "Trunk" then
			local distance = (player.Character.HumanoidRootPart.Position-target.Position).Magnitude
			if distance < 2 then
				if active == true then
					active = false
					wood:Clone().Parent = player:FindFirstChild("Backpack")
					target.Transparency = 1
					target.CanCollide = false
					target.Parent.Leaves.Transparency = 1
					target.Parent.Leaves.CanCollide = false
					wait(5)
					target.Transparency = 0
					target.CanCollide = true
					target.Parent.Leaves.Transparency = 0
					target.Parent.Leaves.CanCollide = true
					active = true
				end
			end
		end
	end
end)

just put in a variable call it hits then increment it every time the tree is hit and add an if statement checking if its equal to the hits that you want for it then inside put the code to destroy it
