What do I add so effects and sounds are only played once if button is clicked multiple times?

Code I have right now:

    local debounce = true

    if debounce then      --Where on the script would I place the debounce stuff?
        debounce = false
        wait(1)
        debounce = true
    end
script.Parent.ClickDetector.MouseClick:Connect(function()                                                             
             --Do I put this in between local debounce and if debounce then?

    game.Workspace.ZooPhotographer.Camera.L.BrickColor = BrickColor.White()
    game.Workspace.ZooPhotographer.Camera.L.PointLight.Brightness = 1
    game.Workspace.ZooPhotographer.Camera.L.PointLight.Range = 8
    game.Workspace.ZooPhotographer.Camera.L.Material = Enum.Material.Neon
    script.Parent.CameraFlash:Play()
    wait(0.25)
    game.Workspace.ZooPhotographer.Camera.L.BrickColor = BrickColor.Black()
    game.Workspace.ZooPhotographer.Camera.L.PointLight.Brightness = 0
    game.Workspace.ZooPhotographer.Camera.L.PointLight.Range = 0
    game.Workspace.ZooPhotographer.Camera.L.Material = Enum.Material.Glass
    script.Parent.CameraFlash:Stop()

end)

What should I fix?

I feel like math would be involved but I am not so sure.

Something along the lines of "'If the button is clicked more than once, the effects and sound cannot be played, but the wait time in the debounce section must pass until the button can be clicked again'".

Thanks! :)
