[Unanswered]The NPC's Animation isn't loading in?

K, so when you approach the NPC's the come towards you, but the animations isnt loading it, and eventually when they swing, it just stops moving.

I've tried basically everything to load in the animation, any help?

Not sure if its the Content Provider area, but the walking is animation is from ROBLOX, and I have it looped. So it should've been working.

local humanoid = script.Parent:WaitForChild("Humanoid")
local torso = script.Parent:WaitForChild("Torso")
local head = script.Parent:WaitForChild("Head2")
local real_head = script.Parent:WaitForChild("Head")
local linked_sword = script.Parent:WaitForChild("Linked_Sword")
local settings = script.Parent:WaitForChild("Settings")
local events = {}
local damage_sounds = {181268610,181268607,181268605}
local hats = {}


--- animations storage ---
local animation_walk = Instance.new("Animation")
animation_walk.AnimationId = "http://www.roblox.com/asset/?id=180426354"
local running_animation_walk = nil

local animation_attack = Instance.new("Animation")
animation_attack.AnimationId = "http://www.roblox.com/asset/?id=1873619820"
local running_animation_attack = nil

function load_hat(id)
local new_hat = game:GetService("InsertService"):LoadAsset(id)
    for i,v in ipairs(new_hat:GetChildren()) do
        if(v.ClassName == "Hat") then
        v.Parent = script.Parent
        end
    end
new_hat:Destroy()
end


Instance.new("ForceField",script.Parent)
--load_hat(hats[math.random(1,#hats)])
    for i = 1,2 do
    wait(0.5)
    humanoid.MaxHealth = settings.Health.Value
    humanoid.Health = settings.Health.Value
    end
script.Parent.ForceField:Destroy()
humanoid.MaxHealth = settings.Health.Value
humanoid.Health = settings.Health.Value




function sound(id,parent,pitch,volume,remove_time)
local sounde = Instance.new("Sound",parent)
game.Debris:AddItem(sounde,remove_time)
sounde.SoundId = "http://www.roblox.com/asset/?id=" .. id
game:GetService("ContentProvider"):Preload(sounde.SoundId)
sounde.Pitch = pitch
sounde.Volume = volume
sounde:Play()
return (sounde)
end





function hurt (human)
    if(human) then
        if(human.Health ~= 0 and human.Parent:FindFirstChild("Torso")) then
        human.Health = human.Health - settings.Damage.Value
        local random_sound_effect = damage_sounds[math.random(1,#damage_sounds)]
        sound(random_sound_effect,human.Parent.Torso,math.random(70,100)/100,1,2)
        end
    end
end




function attack (human)
game:GetService("ContentProvider"):Preload("http://www.roblox.com/asset/?id=94161088")
sound(181268614,linked_sword.Handle,math.random(90,110)/100,1,2)
    if(running_animation_attack == nil and human.Health ~= 0) then
    local event_keyframe_reached
    running_animation_attack = humanoid:LoadAnimation(animation_attack)
    running_animation_attack:Play()
        event_keyframe_reached = running_animation_attack.KeyframeReached:connect(function(keyframeName) -- Bind function to KeyframeReached event
            if (keyframeName == "Hit") then
            hurt(human)

            elseif(keyframeName == "End") then
            running_animation_attack:Stop()
            running_animation_attack = nil
            event_keyframe_reached:disconnect()
            end
        end)

    repeat wait(0.05) until running_animation_attack == nil
    end
end




function walk(operation)
game:GetService("ContentProvider"):Preload("http://www.roblox.com/asset/?id=180426354")
    if(operation == true and running_animation_walk == nil) then
    running_animation_walk = humanoid:LoadAnimation(animation_walk)
    running_animation_walk:Play()


    elseif(operation == false and running_animation_walk ~= nil) then
    running_animation_walk:Stop()
    running_animation_walk = nil
    humanoid:MoveTo(torso.Position,torso)
    end
end

----------Everything else below was basically irrelevant to the loading of the animation-----

function follow(plr,char,dist)
    if(plr and char) then
        if(dist <= settings.Attack_Distance.Value and char:FindFirstChild("Humanoid")) then
        walk(false)
        attack(char.Humanoid)


        elseif(char:FindFirstChild("Humanoid") and dist > settings.Attack_Distance.Value) then
        walk(true)
        script.Parent.Humanoid:MoveTo(char.HumanoidRootPart.Position,char.HumanoidRootPart)
        end

    else
    walk(false)
    end
end
