Changing Default animations doesn't update immediately

Help and Feedback Scripting Support
#1

Hello, I am trying to replace the default walking animation after an event so it smoothly transition , the animation is correctly replaced, however I have to stop and walk again for the new animation to update. (I am not using a tween on the ball, it’s a motor6D with an animation also there is no animation priorities issues.)

Here is a video of my issue :

Here is what I want to achieve :

Here is the code :

function Animation:ChangeDefaultAnim(AnimationID : string, Type : string)
	if not AnimationID or not Type then
		return
	end
	
	local Character = Player.Character or Player.CharacterAdded:Wait()
	local AnimateScript = Character:WaitForChild("Animate")
	
	assert(AnimateScript:FindFirstChild(Type), "Type: "..Type.." not found inside Animate script.")
	
	local Animator = Character:FindFirstChildOfClass("Humanoid").Animator :: Animator
	local TargetAnim = AnimateScript:FindFirstChild(Type):FindFirstChildOfClass("Animation") :: Animation
	
	TargetAnim.AnimationId = AnimationID
end

Thank you.

this is likely because the old animation is still playing, and the change in “AnimationId” doesn’t automatically restart it
try this:

function Animation:ChangeDefaultAnim(AnimationID : string, Type : string)
	if not AnimationID or not Type then
		return
	end
	
	local Character = Player.Character or Player.CharacterAdded:Wait()
	local AnimateScript = Character:WaitForChild("Animate")
	
	assert(AnimateScript:FindFirstChild(Type), "Type: "..Type.." not found inside Animate script.")
	
	local Humanoid = Character:FindFirstChildOfClass("Humanoid")
	local Animator = Humanoid:FindFirstChildOfClass("Animator")
	local TargetAnim = AnimateScript:FindFirstChild(Type):FindFirstChildOfClass("Animation")

	local OldAnimationID = TargetAnim.AnimationId
	
	TargetAnim.AnimationId = AnimationID

	local PlayingTracks = Animator:GetPlayingAnimationTracks()
	for _, track in ipairs(PlayingTracks) do
		if track.Animation.AnimationId == OldAnimationID then
			track:Stop() -- stop the old animation
			local NewTrack = Animator:LoadAnimation(TargetAnim) -- load new animation
			NewTrack:Play() -- play the new anim
		end
	end
end

if there are any errors, lmk

Your script wasn’t working exactly how I intended it but you got me on the right path, I modified it and got it working, to make the animation transition smoothly I used :AdjustWeight(0) instead of stopping the animation

(The code I made is just placeholder and doesn’t look good but if anyone stumble across this here is the solution I found)

local CurrentPlayingAnim = nil

function Animation:ChangeDefaultAnim(AnimationID : string, Type : string)
	if not AnimationID or not Type then
		return
	end

	local Character = Player.Character or Player.CharacterAdded:Wait()
	local AnimateScript = Character:WaitForChild("Animate")

	assert(AnimateScript:FindFirstChild(Type), "Type: "..Type.." not found inside Animate script.")

	local Humanoid = Character:FindFirstChildOfClass("Humanoid") :: Humanoid
	local Animator = Humanoid:FindFirstChildOfClass("Animator")
	local TargetAnim = AnimateScript:FindFirstChild(Type):FindFirstChildOfClass("Animation")
	
	local OldAnimationID = TargetAnim.AnimationId
	local PlayingTracks = Animator:GetPlayingAnimationTracks()
	
	local NewAnimation = Instance.new("Animation")
	NewAnimation.AnimationId = AnimationID
	
	local NewTrack = Animator:LoadAnimation(NewAnimation)
	
	for _, AnimationTrack : AnimationTrack in ipairs(PlayingTracks) do
		if AnimationTrack.Animation.AnimationId == OldAnimationID then
			AnimationTrack:AdjustWeight(0, 0.3) -- stop the old animation by adjusting it's weight to 0 with a 0.3 fade time
			
			NewTrack:Play()
			NewTrack:AdjustWeight(1, 0.3) -- play the animation and adjusting weight so it smoothly transition
			
			CurrentPlayingAnim = NewTrack.Name
		end
	end
	
	if Type == "walk" then
		Humanoid.Running:Connect(function(Speed)
			if Speed > 13 then
				if CurrentPlayingAnim == NewTrack.Name then
					-- prevent the same animation to play multiple time
					return
				end
				
				NewTrack:Play()
				NewTrack:AdjustWeight(1, 0.3)
				
				CurrentPlayingAnim = NewTrack.Name
			else
				NewTrack:AdjustWeight(0, 0.3)
			end
		end)
	end
	
	TargetAnim.AnimationId = AnimationID
end

Thank you very much tho
