Jittery / visually buggy movement animations (especially on turns)

[kanapuro (wanderer)]

you know it baby im back with another problem !!!
clip on youtube since devforum hates any video longer than 10 seconds https://www.youtube.com/watch?v=L9_52ZbAddY
animations for the body is all handled by one local script in the model :3 hell yeah organization!

local uis = game:GetService("UserInputService")
local character = script.Parent
local humanoid = character:FindFirstChild("Humanoid")


-- movement tracks
local walk = script:WaitForChild("Walk")
local walkTrack = humanoid.Animator:LoadAnimation(walk)
local idle = script:WaitForChild("Idle")
local idleTrack = humanoid.Animator:LoadAnimation(idle)

local trotTrack = humanoid.Animator:LoadAnimation(trot)
local run = script:WaitForChild("Run")
local runTrack = humanoid.Animator:LoadAnimation(run)

extra notes: animations “idle” and “crouch” are set as idle animations, “walk”, “trot”, “run”, and “sneak” are set as movement animations and all designed to loop smoothly.

this would be an issue with one of two main things.

there is a problem with the code (most likely) where cframes / bones are overlapping
animations are not fully loaded in (I don’t think this is the cause)

[kanapuro (wanderer)]

I’m not sure what you mean. All animations are made in the Animation Editor, exported, and then uploaded as “Animation” as child of the script. I specifically wrote the code in a way so that they wouldn’t play at the same time (and after lots of testing, they don’t). Did you watch the video? It’d help express my problem - which is that the animations all play perfectly fine, however when the character turns, they jitter/pause for a moment.
(Sorry if I’m misunderstanding, I am a beginner at Luascript )
Edit: The only sort of animation that uses CFrame on the model is the head-turning, I think, which is a whole different issue on another thread haha

[kanapuro (wanderer)]

This problem has not been solved yet.

[Sub2_AlteredMindYT (AlteredMind)]

Have you checked that no animations are overlapping? A good way to do this is use the GetPlayingAnimations() on the humanoid to check if animations are overlapping

[kanapuro (wanderer)]

the only thing that looks like is happening is that the walk animation interrupts itself when turning

edit: ALSO the animations werent experiencing such jittery movement before i implemented q/e to slow down and speed up, so there must be something in my script (shown in original post) causing animations to bug out a little while moving.

edit 2: the script for movement used to look something like this and did not experience pause in animations

-- Very basic walking animation script by GnomeCode
local uis = game:GetService("UserInputService")
local character = script.Parent
local humanoid = character:FindFirstChild("Humanoid")
local emote = false

-- Remeber to select the animtion object and set the id to your own!
local walk = script:WaitForChild("Walk")
local walkTrack = humanoid.Animator:LoadAnimation(walk)

local idle = script:WaitForChild("Idle")
local idleTrack = humanoid.Animator:LoadAnimation(idle)

humanoid.Running:Connect(function(speed)
	if speed > 0 and emote == false then
		if not walkTrack.IsPlaying and idleTrack.IsPlaying then
			idleTrack:Stop()
			walkTrack:Play()
		end
	else
		if walkTrack.IsPlaying and not idleTrack.IsPlaying then
			idleTrack:Play()
			walkTrack:Stop()
		end
	end
end)

idleTrack:Play()

-- emote list :3
local sit = script:WaitForChild("Sit")
local sitTrack = humanoid.Animator:LoadAnimation(sit)

uis.InputBegan:Connect(function(input, gpe)
	if gpe then return end
	if input.KeyCode == Enum.KeyCode.R then
		if emote == false then
			emote = true
			sitTrack:Play()
			humanoid.WalkSpeed = 0
			humanoid.JumpPower = 0
			print("now sitting")
		else
			emote = false
			sitTrack:Stop()
			humanoid.WalkSpeed = 12
			humanoid.JumpPower = 35
			print("now unsitting")
		end
	end
end)

I might have to wait until I fix this other issue first, but I do notice that the animation issue is happening with the head-turning as well, which is the only CFrame-related animation occurring on the player.

So to sum up this bit of information:
The animations jitters, pause, or otherwise cut half-way through when the player is turning the body or the head.

[kanapuro (wanderer)]

I made some changes to the script to account for some weird visual errors I was experiencing with the emotes (such as sitting). I was able to fix some aspects of the animations, but they still pause, hesitate, bug out, whatever haha. So the issue still stands. It’s hard to notice it at first until the player starts trotting & running.
Here’s a clip of current gameplay:

Here’s what the script looks like now:

local uis = game:GetService("UserInputService")

local trotTrack = humanoid.Animator:LoadAnimation(trot)
local run = script:WaitForChild("Run")
local runTrack = humanoid.Animator:LoadAnimation(run)

[UNSOLVED] help needed on improving this movement script

this is a poorly-put-together movement script where pressing q and e will either increase or decrease the player’s speed depending on their current state of movement. the script functions fine, but has some issues: i need to make room/readability for the addition of flying player animations, other emote animations (besides sitting), and attack/tool-based animations: but the script is already fairly fragile in its current state animations tend to bug out on turns/slopes. movement animations wi…
