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)
