Animation plays but barely moves compared to how its supposed to

Hello Developers,

I’m trying to animate a model using moon animator and then trying to have that animation play in game when needed.

When it fires, I want the animation to play properly without stopping.

The animation is definitely playing because the part visibly moves but only a small amount compared to what I actually animated. It looks like the animation is being cut short or barely getting started before something resets it.

How it’s supposed to look:


How it looks in game:

Everything is welded with Motor6D’s.

Part 0 is always the HumanoidRootPart and part is every other part in the model

Code: how animations get set up (shared by every tower type in my game)

function TowerCombatUtils.SetupTowerAnimations(towerModel, config)
	local idleId = config:FindFirstChild("Idle")
	local attackId = config:FindFirstChild("Fire")
	if not idleId and not attackId then return nil end

	local controller = towerModel:FindFirstChildOfClass("Humanoid") or towerModel:FindFirstChildOfClass("AnimationController")
	if not controller then return nil end

	local animator = controller:FindFirstChildOfClass("Animator")
	if not animator then
		animator = Instance.new("Animator")
		animator.Parent = controller
	end

	local tracks = {}

	if idleId and idleId:IsA("Animation") then
		local success, trackOrError = pcall(function() return animator:LoadAnimation(idleId) end)
		if success then
			trackOrError.Priority = Enum.AnimationPriority.Idle
			trackOrError.Looped = true
			trackOrError:Play()
			tracks.Idle = trackOrError
		end
	end

	if attackId and attackId:IsA("Animation") then
		local success, trackOrError = pcall(function() return animator:LoadAnimation(attackId) end)
		if success then
			trackOrError.Priority = Enum.AnimationPriority.Action
			trackOrError.Looped = false
			tracks.Attack = trackOrError
		end
	end

	return tracks
end

Code: how the attack animation actually gets played and synced to firing

Right now I think this part could be the most important. Cooldown here is the tower’s fire rate. This whole thing runs every time the tower attacks:

if animationTracks and animationTracks.Attack then
	local attackAnim = animationTracks.Attack

	local animLength = attackAnim.Length
	if animLength > 0 and cooldown < animLength then
		attackAnim:AdjustSpeed(animLength / cooldown)
	else
		attackAnim:AdjustSpeed(1)
	end

	attackAnim.TimePosition = 0
	attackAnim:Play()

	local fireMarkerConnection
	local keyframeConnection

	fireMarkerConnection = attackAnim:GetMarkerReachedSignal("Fire"):Connect(performAttack)
	keyframeConnection = attackAnim.KeyframeReached:Connect(function(keyName)
		if keyName == "Fire" or keyName == "fire" then performAttack() end
	end)

	local waitTime = attackAnim.Length > 0 and (attackAnim.Length / attackAnim.Speed) or 1
	task.delay(waitTime + 0.05, function()
		if not fired then performAttack() end
		if fireMarkerConnection then fireMarkerConnection:Disconnect() end
		if keyframeConnection then keyframeConnection:Disconnect() end
	end)
else
	performAttack()
end

The animation’s length is not longer than the cooldown.

I don’t believe it’s an issue with animation priority either. Because this logic works for all my other humanoid towers and they work exactly the same.

If anyone has any idea why this is occuring it would be great to know.

All help is appreciated!

I think this has something to do with AdjustSpeed, precisely this line here:

if animLength > 0 and cooldown < animLength then
		attackAnim:AdjustSpeed(animLength / cooldown)
	else

Have you tried disabling this to see if your speed adjuster simply plays the animation too fast?

another suggestion: try playing the animation without anything, an animation loader and :Play() and see if its doing that too, also assume .Priority = Enum.AnimationPriority. might be somewhat buggy

Play the animation with no fade time. Should be as simple as;

	attackAnim:Play(0)
