How to modify speed of modified default roblox animations?

In my game, I have a parkour system where you gain speed by running for a while. However, the walk animations are just overwritten roblox walk animations.

Here’s the script:

game.Players.PlayerAdded:Connect(function(plr)
	plr.CharacterAdded:Connect(function(char)

	local hum = char:WaitForChild("Humanoid")
		local hrp = char:WaitForChild("HumanoidRootPart")
		local anims = char:WaitForChild("Animate")
		
		anims.walk.WalkAnim.AnimationId = "rbxassetid://74947900635575"
		anims.jump.JumpAnim.AnimationId = "rbxassetid://133746227608901"
		anims.fall.FallAnim.AnimationId = "rbxassetid://131422754475209"
end)

Because these are “animation” objects, and not “AnimationClip” objects, I can’t use the :AdjustSpeed() method on them. I don’t exactly know what to do, and I can’t seem to find another post about this specific issue in my case.

You could make your own animations, but then again you can also make a custom solution, where you do turn those animations into animationtracks and using states. There are probably implementations for this, but you could do something like:

-- CustomAnimate LocalScript

local Players = game:GetService("Players")
local RunService = game:GetService("RunService")

local player = Players.LocalPlayer
local character = player.Character or player.CharacterAdded:Wait()
local humanoid = character:WaitForChild("Humanoid")

-- Load Custom Animations
local walkAnim = Instance.new("Animation")
walkAnim.AnimationId = "rbxassetid://74947900635575"

local jumpAnim = Instance.new("Animation")
jumpAnim.AnimationId = "rbxassetid://133746227608901"

local fallAnim = Instance.new("Animation")
fallAnim.AnimationId = "rbxassetid://131422754475209"

-- Create Animation Tracks
local animator = humanoid:WaitForChild("Animator") or humanoid:FindFirstChildWhichIsA("Animator")
if not animator then
    animator = Instance.new("Animator")
    animator.Parent = humanoid
end

local walkTrack = animator:LoadAnimation(walkAnim)
local jumpTrack = animator:LoadAnimation(jumpAnim)
local fallTrack = animator:LoadAnimation(fallAnim)

-- Ensure animations loop appropriately
walkTrack.Looped = true
jumpTrack.Looped = false
fallTrack.Looped = false

-- Function to Adjust Animation Speed Based on Player Speed
local function adjustAnimationSpeed()
    -- Example: Base walk speed
    local baseWalkSpeed = 16 -- Default Roblox walk speed

    -- Get current speed from your parkour system
    -- Replace this with your actual method of obtaining the player's current speed
    local currentSpeed = humanoid.WalkSpeed -- Modify as needed

    -- Calculate speed multiplier
    local speedMultiplier = currentSpeed / baseWalkSpeed

    -- Clamp the multiplier to prevent extreme speeds
    speedMultiplier = math.clamp(speedMultiplier, 0.5, 2)

    -- Adjust animation playback speeds
    walkTrack.PlaybackSpeed = speedMultiplier
    jumpTrack.PlaybackSpeed = speedMultiplier
    fallTrack.PlaybackSpeed = speedMultiplier
end

-- Connect the speed adjustment to the RenderStepped event for smooth updates
RunService.RenderStepped:Connect(adjustAnimationSpeed)

-- Optional: Handle Jump and Fall States
humanoid.StateChanged:Connect(function(oldState, newState)
    if newState == Enum.HumanoidStateType.Jumping then
        jumpTrack:Play()
    elseif newState == Enum.HumanoidStateType.Freefall then
        fallTrack:Play()
    end
end)

I am not responsible for the quality of this script :wink:

You can only adjustspeed on animation tracks rather then the animation instance. There is this built in function for the animator instance you can use by getting current animations playing.

--> Services
local players = game:GetService("Players")

--> Variables
local player = players.LocalPlayer
local character = player.Character or player.CharacterAdded:Wait()
local humanoid = character:WaitForChild("Humanoid") :: Humanoid
local animator = humanoid.Animator

---------------------------------------------------------------

local function SetAnimationSpeed(Animename: string, speed: number) : AnimationTrack
	for index : number, animation : AnimationTrack in animator:GetPlayingAnimationTracks() do
		if animation.Length > 0 and string.match(tostring(animation), Animename) then
			animation:AdjustSpeed(speed)
			return animation
		end
	end
end

--> Events
humanoid.Running:Connect(function(speed: number)
	local animation = SetAnimationSpeed("RunAnim", 5) -- Animation Name and speed to set the animation speed
	print(speed, animation)
end)

Note that you can do more events other than then the humanoid running like humanoid states.

Okay, i’ll make sure to try out this method, and tell you what happens.
