[SOLVED] My automatic gun does not work how I expected?

So here's the deal; I tried making an automatic gun but failed. If I hold my mouse button it will work how I intended, but as soon as I spam the gun it shoots out the bullets extremely fast. The ammo counter will also decrease dramatically. Is there any way fix to this? Any answer is appreciated!

Most of the script (You might have to press view source):

script.Parent.Equipped:Connect(function(mouse)
    canReload = true
    ammoGui.Text = ammo.." / "..maxAmmo

    canIdle = true

    script.Parent.Unequipped:Connect(function()
        canIdle = false
        canReload = false
        canShoot = false
        shooting = false

        ammoGui.Text = "---"

        equipAnim:Stop()
        idleAnim:Stop()
        shootAnim:Stop()
    end)

    humanoid.Died:Connect(function()
        canReload = false
        canIdle = false
        canShoot = false
        shooting = false
    end)

    equipAnim:Play()

    wait(equipAnim)

    if canIdle then
        idleAnim:Play()
    end

    local function Reload()
        if canReload then
            ammoGui.Text = "---"
            reloading = true
            reloadAnim:Play()

            wait(reloadAnim.Length)

            ammo = maxAmmo
            ammoGui.Text = ammo.." / "..maxAmmo
            reloading = false
        end
    end

                    end
                end

                local ranSpreadX, ranSpreadY, ranSpreadZ = math.random(-spread, spread), math.random(-spread, spread), math.random(-spread, spread)

                game.ReplicatedStorage:WaitForChild("RemoteEvents"):WaitForChild("RaycastEvent"):FireServer(script.Parent:WaitForChild("Flame").Position, mouse.Hit.Position, math.random(2,8), Vector3.new(ranSpreadX, ranSpreadY, ranSpreadZ))
