How do I make my custom run animation sync with the WalkSpeed?

Basically I want my customized-animated run animation to sync with the WalkSpeed the player is going, although I don’t know how to entirely script that.

Along with that, I want my walk animation to be minimal of the speed of 1 - 8, therefore then changing to the run-animation where it will accelerate faster depending on the walkspeed the player or NPC is going.

I think you have to code your animation for it to according to the speed of the WalkSpeed.

you don’t, there’s a way to script out your animation and sync it to walkspeed.

You can override the default animations that are put into the player’s character to do this. In order to get access to the default animation script and animations, run your game and navigate to your player’s character model in the workspace. Copy the animation script, stop the game, and paste it into your StarterCharacterScripts. Placing it there will override the default animation script with that one, including any edits you add to it. In the script you copied over, you can edit all the animation ID’s in certain areas to your own ID’s. These include the running and walking animations.

but the custom run animation does not sync with the walkspeed.

You can probably create a connection to RunService.Heartbeat that speeds up or slows down your animation track based on Humanoid:GetMoveVelocity().Magnitude.

You could additionally create a connection to disconnect the heartbeat connection when the animation track finishes.

If you replace the walking animation with something different, it should sync to the walkspeed and work just like a regular walking animation. The character code can we weird though, so there might be something off about it.

I’ll see what I can do, I’ll reply if there’s any issues or furthermore, I’ve scripted it.

Unfortunately I tried, I’m not very advanced with things such as heartbeats and getmovevelocity: ,I’m only advanced at certain things.

Here is some code I wrote, I haven’t tested it. The other method might be easier if it’s just for a walking animation.

local RunService = game:GetService("RunService")

local REGULAR_WALK_SPEED = 5 -- Pick a number to make the speed right

local function createConnection(animationTrack, humanoid)
    -- Will adjust the animation speed until we stop it
    local connection = RunService.Heartbeat:Connect(function()
        local humanoidWalkSpeed = humanoid:GetMoveVelocity().Magnitude
        local animationSpeed = humanoidWalkSpeed / REGULAR_WALK_SPEED
        animationTrack:AdjustSpeed(animationSpeed)
    end)
    -- Returns a function to stop the adjustments
    return function()
        connection:Disconnect()
    end
end

-- Example usage
local humanoid = ...
local animationTrack = ...

local stopFunction = createConnection(animationTrack, humanoid)
-- Now the animationTrack will be adjusted by the humanoid's move speed until we run stopFunction

-- Say we want the adjustment to stop when the animation track ends
animationTrack.Ended:Once(stopFunction)

-- Stop adjusting if the humanoid is destroyed
humanoid.AncestryChanged:Connect(function(_, newParent)
    if newParent == nil then
        stopFunction()
    end
end)

I’ll test it out, and see how well it does.

I’m not sure where that error is, it might be from how the code was used. I’m also not sure if the GetMoveVelocity function is meant to be exposed though (the new docs suck).

Here is some code to run from the server:

local function switchWalk(character, newAnimation)
    local walkValue = character:WaitForChild("Animate"):WaitForChild("walk")
    local oldWalkAnim = walkValue:FindFirstChildOfClass("Animation")
    oldWalkAnim:Destroy()
    local newWalkAnim = newAnimation:Clone()
    newWalkAnim.Parent = walkValue
end

local function switchRun(character, newAnimation)
    local runValue = character:WaitForChild("Animate"):WaitForChild("run")
    local oldRunAnim = runValue:FindFirstChildOfClass("Animation")
    oldRunAnim:Destroy()
    local newRunAnim = newAnimation:Clone()
    newRunAnim.Parent = walkValue
end

I’ll test it out now, and I’ll let you know if it works.

Unfortunately it doesn’t work, thanks for trying though.

I had a typo (I had the run animation be parented to walkValue but it should have been runValue), maybe try it now. Set your run animation to both the walk and run animation. newAnimation should be an Animation. It has to be done from the server too.

local function switchWalk(character, newAnimation)
    local walkValue = character:WaitForChild("Animate"):WaitForChild("walk")
    local oldWalkAnim = walkValue:FindFirstChildOfClass("Animation")
    oldWalkAnim:Destroy()
    local newWalkAnim = newAnimation:Clone()
    newWalkAnim.Parent = walkValue
end

local function switchRun(character, newAnimation)
    local runValue = character:WaitForChild("Animate"):WaitForChild("run")
    local oldRunAnim = runValue:FindFirstChildOfClass("Animation")
    oldRunAnim:Destroy()
    local newRunAnim = newAnimation:Clone()
    newRunAnim.Parent = runValue
end

I tried it in studio with this code and it worked:

local function switchWalk(character, newAnimation)
	local walkValue = character:WaitForChild("Animate"):WaitForChild("walk")
	local oldWalkAnim = walkValue:FindFirstChildOfClass("Animation")
	oldWalkAnim:Destroy()
	local newWalkAnim = newAnimation:Clone()
	newWalkAnim.Parent = walkValue
end

local function switchRun(character, newAnimation)
	local runValue = character:WaitForChild("Animate"):WaitForChild("run")
	local oldRunAnim = runValue:FindFirstChildOfClass("Animation")
	oldRunAnim:Destroy()
	local newRunAnim = newAnimation:Clone()
	newRunAnim.Parent = runValue
end

game:GetService("Players").PlayerAdded:Connect(function(player)
	player.CharacterAdded:Connect(function(character)
		-- Set to some animation
		local animation = character:WaitForChild("Animate"):WaitForChild("dance"):FindFirstChildOfClass("Animation")
		switchWalk(character, animation)
		switchRun(character, animation)
	end)
end)
