How to add a cooldown to the animation code?

Hello (again)! I have attempted to implement a wait time into every line of the code shown down below, and nothing has managed to delay the animation. I'm sorry about taking up so much room on the question board, but I really want to get this animation over with so I can get back to modeling.

local plr = game.Players.LocalPlayer
local char = plr.Character or plr.CharacterAdded:wait()
local tool = script.Parent
local swingsound = tool:WaitForChild("Swing")
local canattack = tool:WaitForChild("CanAttack")
local Punch1 = Instance.new("Animation")
Punch1.AnimationId = "rbxassetid://4921775472"
local Punch2 = Instance.new("Animation")
Punch2.AnimationId = "rbxassetid://4921778051"
local cooldown = 1

tool.Activated:connect(function()
	local choose = math.random(1,2)
	canattack.Value = true
	if choose == 1 then
		local swing1animation = script.Parent.Parent.Humanoid:LoadAnimation(Punch1)
		swingsound:Play()
		swing1animation:Play()
	elseif choose == 2 then
		local swing2animation = script.Parent.Parent.Humanoid:LoadAnimation(Punch2)
		swingsound:Play()
		swing2animation:Play()
	end
end)

tool.Deactivated:connect(function()
	canattack.Value = true
end)

tool.Unequipped:connect(function()
	local hum = char:WaitForChild("Humanoid")
	for _,anim in pairs(hum:GetPlayingAnimationTracks()) do
 		anim:Stop()
	end
end)

Thanks again!

fix (i think):

local plr = game.Players.LocalPlayer
local char = plr.Character or plr.CharacterAdded:wait()
local tool = script.Parent
local swingsound = tool:WaitForChild("Swing")
local canattack = tool:WaitForChild("CanAttack")
local Punch1 = Instance.new("Animation")
Punch1.AnimationId = "rbxassetid://4921775472"
local Punch2 = Instance.new("Animation")
Punch2.AnimationId = "rbxassetid://4921778051"
local cooldown = 1

tool.Activated:connect(function()
    local choose = math.random(1,2)
    canattack.Value = true
    if choose == 1 then
	wait(cooldown)
        local swing1animation = script.Parent.Parent.Humanoid:LoadAnimation(Punch1)
        swingsound:Play()
        swing1animation:Play()
    elseif choose == 2 then
	wait(cooldown)
        local swing2animation = script.Parent.Parent.Humanoid:LoadAnimation(Punch2)
        swingsound:Play()
        swing2animation:Play()
    end
end)

tool.Deactivated:connect(function()
    canattack.Value = true
end)

tool.Unequipped:connect(function()
    local hum = char:WaitForChild("Humanoid")
    for _,anim in pairs(hum:GetPlayingAnimationTracks()) do
        anim:Stop()
    end
end)
