local animation = Instance.new("Animation")
local psuedoanimetrack

local playablity = true
local ape = script.Parent
local animetable ={
    idle ="http://www.roblox.com/Asset?ID=1265687850",
    run ="http://www.roblox.com/Asset?ID=1265540413"

    }

function playdaanime (animName,humanoid)
    local anin = animetable[animName]
    animation.AnimationId= anin
    psuedoanimetrack= humanoid:LoadAnimation(animation)
    psuedoanimetrack:Play()
end
wait(10)

while true do
    local speed = Vector3.new(ape.HumanoidRootPart.Velocity.X, 0, ape.HumanoidRootPart.Velocity.Z).magnitude
    if playablity and speed >.5 then
        print("im moving")
        playablity = false
        playdaanime("run",ape.Humanoid)

        psuedoanimetrack.KeyframeReached:connect(function()
            print("im done moving")
            playablity= true
        end)

    elseif playablity then
        print("im idle")
    playablity = false

        playdaanime("idle",ape.Humanoid)
        psuedoanimetrack.KeyframeReached:connect(function()
            print("im done in idle")
            playablity= true
        end)
