I need help on a script that will make three punches throw consecutively . Could anyone help?

I have three different punching animations called animation1 animation2 and animation3 in the script. I need someones help trying to allow the** script to do one punch then press f again in a period of like 0.5 seconds** (after the first one finished)** to activate a second one and then another one in another period of 0.5 seconds after the second one finished**. I was thinking else return might work but it didn't. Also, if they dont press f inbetween after the other one finished then it to cancel out. Also i** dont want it to keep restarting the punch by spamming f**. I know this sounds a lot but this is out of my area of thinking. Any help would be appreciated. Thanks.

CanDoDmg = true -- If the player can do damage
Keybind1 = "f"
Keybind2 = "f"
Keybind3 = "f" -- Keybind to activate the punch
dmg = 20 -- How much damage the player takes


local plr = game.Players.LocalPlayer
local mouse = plr:GetMouse()

mouse.KeyDown:Connect(function(key)
	if key == Keybind1 then
		local anim = script.Parent.Humanoid:LoadAnimation(script.Animation1)
		anim:Play() 
		wait()
		script.Parent.RightHand.Touched:connect(function(hit)
			if hit.Parent.Humanoid and CanDoDmg == true then
			hit.Parent.Humanoid:TakeDamage(dmg)
			CanDoDmg = false
			wait(1)
				CanDoDmg = true
				
				
mouse.KeyDown:Connect(function(key)
	if key == Keybind2 then 
		local anim = script.Parent.Humanoid:LoadAnimation(script.Animation2)
		anim:Play() 
		wait()
		script.Parent.RightHand.Touched:connect(function(hit)
			if hit.Parent.Humanoid and CanDoDmg == true then
			hit.Parent.Humanoid:TakeDamage(dmg)
			CanDoDmg = false
			wait(1)
				CanDoDmg = true				
								
mouse.KeyDown:Connect(function(key)
	if key == Keybind3 then
		local anim = script.Parent.Humanoid:LoadAnimation(script.Animation3)
		anim:Play() 
		wait()
		script.Parent.RightHand.Touched:connect(function(hit)
			if hit.Parent.Humanoid and CanDoDmg == true then
			hit.Parent.Humanoid:TakeDamage(dmg)
			CanDoDmg = false
			wait(1)
				CanDoDmg = true				
								
						
								
								
								

			end
		end)
	end
end)

You can encode the punch level as a numeric variable and check it like so:

local CanDoDmg = true -- If the player can do damage
local Keybind = "f"
local damage = 20 -- How much damage the player takes

local punch_level = 0
local punch_animations = {script.Animation1, script.Animation2, script.Animation3}

local plr = game.Players.LocalPlayer
local mouse = plr:GetMouse()

mouse.KeyDown:Connect(function(key)
    if key == Keybind then
        if punch_level < 3 then
	    punch_level += 1 -- increase punch level, unless it's already the maximum
        else
            -- Abort the punch, because we don't have a 4th animation.
            -- If you'd like it do something else, please say so in a comment.
            return
        end
        local anim = script.Parent.Humanoid:LoadAnimation(punch_animations[punch_level])
        anim:Play()

        -- Removed a wait() here

        script.Parent.RightHand.Touched:connect(function(hit)
            if hit.Parent.Humanoid and CanDoDmg == true then
                hit.Parent.Humanoid:TakeDamage(dmg)
                CanDoDmg = false
                wait(1)
                CanDoDmg = true
            end
        end)

        local saved_punch_level = punch_level
        wait(0.5)
        if punch_level == saved_punch_level then
            -- This code is only executed if the player hasn't initiated another punch.
            punch_level = 0
        end
    end
end)

To go through the logic:

• Every time the player punches, the punch level is increased (unless the level is already the maximum).
• After 0.5 seconds, the punch level is reset to 0, unless the player has initiated another punch (in which case it isn't changed).
• The initiation of another punch is detected by checking if the current punch_level is the same as it was before waiting.
