Can't get my animation to play slower?

[matt1020304050]

So even though I use the AdjustSpeed property, the animation plays at the same speed.

function playAnimation(whichAnim, looped, stop, speed)
	if stop then
	for i,v in pairs(humanoid:GetPlayingAnimationTracks()) do
		v:Stop()
		end
	end
local Animator = humanoid:WaitForChild("Animator")
	local shockAnimation = Instance.new("Animation")
	shockAnimation.AnimationId = "rbxassetid://"..whichAnim
	local shockAnimationTrack = Animator:LoadAnimation(shockAnimation)
		shockAnimationTrack:AdjustSpeed(0.5)
	shockAnimationTrack.Priority = Enum.AnimationPriority.Action
	shockAnimationTrack.Looped = looped
	shockAnimationTrack:Play()
end


playAnimation(myAnim, true, true, true)

You can’t adjust speed before playing the animation, try playing the animation then adjusting the speed

Use AdjustSpeed after you play, or use the speed argument in :Play(fadetime, weight, speed)
