Change Walk, Run and Idle animations

[A4THU4O800 (NRArthur)]

I am making a crouch function, in which the animation of Idle, Walk and Run change, the method I am using is to change the AnimationId of the animations, something like this:

--Animaciones
local animacionAgachado = "rbxassetid://id"
local animacionIdleAgachado = "rbxassetid://id"
local walkAnimOriginal
local runAnimOriginal

local idleAnimOriginal
local idleAnimOriginal2

--Funcion para actualizar la animacion a agacharse o normal
local function cambiarAnimacion(agacharse)
	local character = player.Character
	local humanoid = character:WaitForChild("Humanoid")
	
	--Funciona solo si se encuentra al humanoid
	if character then
		local animacionScript = character:WaitForChild("Animate")
	
		--Funciona solo si se encuentra al script
		if animacionScript then
			if not walkAnimOriginal and not runAnimOriginal and not idleAnimOriginal and not idleAnimOriginal2 then
				walkAnimOriginal = animacionScript.walk.WalkAnim.AnimationId
				runAnimOriginal = animacionScript.run.RunAnim.AnimationId
				idleAnimOriginal = animacionScript.idle.Animation1.AnimationId
				idleAnimOriginal2 = animacionScript.idle.Animation2.AnimationId
			end
			
			
			if agacharse == true then
				animacionScript.run.RunAnim.AnimationId = animacionAgachado
				animacionScript.walk.WalkAnim.AnimationId = animacionAgachado
				animacionScript.idle.Animation1.AnimationId = animacionIdleAgachado
				animacionScript.idle.Animation2.AnimationId = animacionIdleAgachado
				
			elseif agacharse == false then				
				animacionScript.run.RunAnim.AnimationId = runAnimOriginal
				animacionScript.walk.WalkAnim.AnimationId = walkAnimOriginal
				animacionScript.idle.Animation1.AnimationId = idleAnimOriginal
				animacionScript.idle.Animation2.AnimationId = idleAnimOriginal2
			end
			
		end
	end
end

However, the crouch animations only start playing if the player walks or stops, for example, in the Idle animation, I have to move forward for the crouch animation to play and vice versa, also with the Walk and Run animations , I have to stop and go again for them to play correctly.

My question is how can I solve this or if there are more pragmatic methods.

I recommend handling crouch animations separate from the Animate script, this should work to achieve what you’re looking for (LocalScript in StarterCharacterScripts):

local ContextActionService = game:GetService("ContextActionService")

local ANIMATION_TRACKS = {
	Idle = "rbxassetid://", -- The crouch idle animation asset ID
	Run = "rbxassetid://", -- The crouch run animation asset ID
	Walk = "rbxassetid://" -- The crouch walk animation asset ID
}

local FADE_TIME = 0.1 -- The default fade time to be used by the animation tracks

local WALK_SPEED = 16 -- Values greater-than this number will be considered running 

local character = script.Parent
local humanoid = character:WaitForChild("Humanoid")
local animator = humanoid:WaitForChild("Animator")

for name, animationId in ANIMATION_TRACKS do
	local animation = Instance.new("Animation")
	animation.AnimationId = animationId

	local animationTrack = animator:LoadAnimation(animation)
	animationTrack.Priority = Enum.AnimationPriority.Action4 -- You might need to lower this if it causes conflicts with other animations

	ANIMATION_TRACKS[name] = animationTrack

	animation:Destroy()
end

local animationTrack = ANIMATION_TRACKS.Idle

local connection

local crouching = false

local function play(newTrack, fadeTime)
	local fadeTime = fadeTime or FADE_TIME

	animationTrack:Stop(fadeTime)
	animationTrack = newTrack
	animationTrack:Play(fadeTime)
end

local function onRunning(speed: number)
	if crouching then
		local speed = math.round(speed)

		if speed > 0 and speed <= WALK_SPEED then -- Walking
			play(ANIMATION_TRACKS.Walk)
		elseif speed > WALK_SPEED then -- Running
			play(ANIMATION_TRACKS.Run)
		else -- Idling
			play(ANIMATION_TRACKS.Idle)
		end
	else
		animationTrack:Stop(FADE_TIME)
	end
end

ContextActionService:BindAction("Crouch", function(_, inputState: Enum.UserInputState)
	if inputState == Enum.UserInputState.Begin then
		if connection then return end

		crouching = true

		onRunning(humanoid.RootPart.AssemblyLinearVelocity.Magnitude)

		connection = humanoid.Running:Connect(onRunning)
	else
		if connection then
			connection:Disconnect()
			connection = nil

			crouching = false

			onRunning(0)
		end
	end
end, false, Enum.KeyCode.C)

It’s safe to edit the values that have comments explaining what they do
