My Debounce is not working properly?

The answer is the debounce has got to check if the firing is not false, which will then set it to true. You could make this look simpler by not putting it on the same line, but checking that both of them are correct to continue with your script.

Not entirely sure if this will work, but it's worth a shot.

Code:

local firing = false

Mouse.Button1Down:Connect(function(Mouse)
    if active then
        if not firing then
            Firing = true
            Dead()
            TankRnd()
            wait(5)
            firing = false
        end
    end
end)

Please accept my answer if this works for you.

Mouse.Button1Down:Connect(function(Mouse)
    if Active then
        if not Firing then
            if Firing then
                return
            end
            Firing = true
            Dead()
            CreateBullet()
            wait(1.5)
            Firing = false
        end
    end
end)

This is it. Figured it out.....thank you all so much for all the help. Really appreciate it

The problem is (I think) is you need to put wait(5) and Firing =true in the if statement in order it to work and you have to set local firing = true outside the function block so the script should be

 local Firing = true

Mouse.Button1Down:Connect(function(Mouse)
    if active then
     if Firing then
        Dead()
        TankRnd()
    wait(5)
    Firing = true
    end
    end
end)
