How might I play the animation in this Shift to Sprint Script?

Help and Feedback Scripting Support

Yeah. Moving direction is NAN. I think magnitude should work though. Try it out.

#22

So i’ve got this script right here:

local PlayersService = game:GetService("Players")
local UIS = game:GetService("UserInputService")
local animation = Instance.new("Animation")
animation.AnimationId = "http://www.roblox.com/asset/?id=9360403056"


local playerEntity = PlayersService.LocalPlayer
local character = playerEntity.Character or playerEntity.CharacterAdded:Wait()
local characterHumanoid = character:WaitForChild("Humanoid")

local normalSpeed = 16
local boostedSpeed = normalSpeed * 1.25

local Anim = characterHumanoid:WaitForChild("Animator"):LoadAnimation(animation)

local function startSprinting(key)
	if key.KeyCode == Enum.KeyCode.LeftShift and characterHumanoid.MoveDirection.Magnitude > 0 then
		characterHumanoid.WalkSpeed = boostedSpeed
		Anim:Play() -- To Play
	end
end

local function stopSprinting(key)
	if key.KeyCode == Enum.KeyCode.LeftShift or characterHumanoid.MoveDirection.Magnitude <= 0 then
		characterHumanoid.WalkSpeed = normalSpeed
		Anim:Stop()-- To Stop
	end
end

UIS.InputBegan:Connect(startSprinting)
UIS.InputEnded:Connect(stopSprinting)

However yet again, this breaks the script. It has not errors, but it doesn’t function.

Try this

local PlayersService = game:GetService("Players")
local UIS = game:GetService("UserInputService")


local playerEntity = PlayersService.LocalPlayer
local character = playerEntity.Character or playerEntity.CharacterAdded:Wait()
local characterHumanoid = character:WaitForChild("Humanoid")

local animation = Instance.new("Animation")
animation.AnimationId = "http://www.roblox.com/asset/?id=9360403056"
Anim = character.characterHumanoid.Animator:LoadAnimation(animation)

local normalSpeed = 16
local boostedSpeed = normalSpeed * 1.25

local function startSprinting(key)
	if key.KeyCode == Enum.KeyCode.LeftShift then
		if characterHumanoid.MoveDirection.Magnitude > 0 then
			Anim:Play()
			characterHumanoid.WalkSpeed = boostedSpeed
		end

	
	end
end

local function stopSprinting(key)
	if key.KeyCode == Enum.KeyCode.LeftShift or key.KeyCode == Enum.KeyCode.W then
		Anim:Stop()
		characterHumanoid.WalkSpeed = normalSpeed
	end
end

UIS.InputBegan:Connect(startSprinting)
UIS.InputEnded:Connect(stopSprinting)

If there are any errors please tell me because I haven’t tested this yet.

It breaks the script sadly. I believe it might be because there is an if statement inside of an if statement. Testing the hopeful solution right now.

#25

It did not function as I hoped, it still remained broken.

#26

You can put as many if statements as you want. You can have else and put an if.

#27

Do you get any errors? Did you put end?

#28

Yes. I did do so, it still remained broken.

#29

Can you try this now?

local PlayersService = game:GetService("Players")
local UIS = game:GetService("UserInputService")


local playerEntity = PlayersService.LocalPlayer
local character = playerEntity.Character or playerEntity.CharacterAdded:Wait()
local Humanoid = character:FindFirstChildWhichIsA("Humanoid")

local animation = Instance.new("Animation")
animation.AnimationId = "http://www.roblox.com/asset/?id=9360403056"
Anim = Humanoid.Animator:LoadAnimation(animation)

local normalSpeed = 16
local boostedSpeed = normalSpeed * 1.25

local function startSprinting(key)
	if key.KeyCode == Enum.KeyCode.LeftShift then
		if Humanoid.MoveDirection.Magnitude > 0 then
			Anim:Play()
			Humanoid.WalkSpeed = boostedSpeed
		end

	
	end
end

local function stopSprinting(key)
	if key.KeyCode == Enum.KeyCode.LeftShift then
		Anim:Stop()
		Humanoid.WalkSpeed = normalSpeed
	end
end

UIS.InputBegan:Connect(startSprinting)
UIS.InputEnded:Connect(stopSprinting)

Again, any errors? At all? Search your script name in output. Even a warning is important especially if it’s an “Infinite yield possible on WaitForChild”

#31

No errors, for some reason? It doesn’t show anything.

#32

Then there’s no syntax error and an annoying error which doesn’t well you what’s wrong… Because there’s nothing wrong. Why don’t you have a set speed on the running speed by the way?

#33

I had made a variable for the normal speed so I decided to multiply it instead of set it.

I have solved the issue, thank you all for the help that you gave.
