How do I get this NPC to stop moving towards the player when it punches? [Solved]

So I made this script to make an NPC punch when it gets within a certain distance of the player but the problem is that when it punches it doesn't stop moving towards the player which makes it hard to evade the punch. So how would I get it to stop when it punches the player?

Here is the code:

local larm = script.Parent:FindFirstChild("HumanoidRootPart")
local rarm = script.Parent:FindFirstChild("HumanoidRootPart")
local punchdist = 10
local animation = Instance.new("Animation")
animation.AnimationId = "http://www.roblox.com/Asset?ID=02568852350"
local Humanoid = script.Parent:FindFirstChild("Robot")
animTrack = Humanoid:LoadAnimation(animation)
local CanPunch = true

function punch()
    if CanPunch then
        CanPunch = false
        animTrack:Play()
        wait(0.75)
        animTrack:Stop()
        CanPunch = true
    end
end

function findNearestTorso(pos)
    local list = game.Workspace:children()
    local torso = nil
    local dist = 100
    local temp = nil
    local human = nil
    local temp2 = nil
    for x = 1, #list do
        temp2 = list[x]
        if (temp2.className == "Model") and (temp2 ~= script.Parent) then
            temp = temp2:findFirstChild("HumanoidRootPart")
            human = temp2:findFirstChild("Humanoid")
            if (temp ~= nil) and (human ~= nil) and (human.Health > 0) then
                if (temp.Position - pos).magnitude < dist then
                    torso = temp
                    dist = (temp.Position - pos).magnitude
                end
            end
        end
    end
    return torso
end




while true do
    wait(1)
    local target = findNearestTorso(script.Parent.HumanoidRootPart.Position)
    if target ~= nil then
        script.Parent.Robot:MoveTo(target.Position, target)
        if punchdist >= (target.Position - script.Parent.HumanoidRootPart.Position).magnitude then
            punch()
        end
    end

end
