Me and a friend are currently building a game and I would like to implement some sort of shift to sprint with a custom animation. Currently I’ve figured out how to do a shift to sprint script which simply increases the player’s walkspeed to ~30, I’ve also made an animation (Here: https://create.roblox.com/marketplace/asset/13510270711) (<- moochers clicking that link) with Moon Animator (priority set to action).
However I have not been able to figure out how to make this animation play… well at all really, I can’t get it to play while holding shift, i cant get it to play while holding shift and moving, it just doesn’t work. I’ve checked the Roblox Creator API and couldn’t figure it out.
I checked the devforum and found this post which seemed promising but didn’t seem to work (it has it’s own shift to sprint script which didnt work (and didn’t work in conjunction to mine)).
Insert an animation into the local script and set the animation id to 13510270711, then in your script do this
local Animation = script:WaitForChild("YourAnimationName")
local AnimTrack = Humanoid:LoadAnimation(Animation)
-- In your sprinting part
Animation:Play()
-- When the player stops sprinting do
Animation:Stop()
Seems like it would work but sadly it doesn’t… OH very important note, I’m using @MaximumADHD’s Realism Script, if that could be influencing it then i need to find some way to make both work
heres the script so far
local Players = game:GetService("Players")
local player = Players.LocalPlayer
local Humanoid = player.Character:WaitForChild("Humanoid")
local sprintSpeed = 30
local walkSpeed = 16
local Animation = script:WaitForChild("RunAnim")
local AnimTrack = Humanoid:LoadAnimation(Animation)
local userInput = game:GetService("UserInputService")
local function beginSprint(input, gameProcessed)
if not gameProcessed then
if input.KeyCode == Enum.KeyCode.LeftShift then
player.Character.Humanoid.WalkSpeed = sprintSpeed
Animation:Play() -- Play the run animation
end
end
end
local function endSprint(input, gameProcessed)
if not gameProcessed then
if input.KeyCode == Enum.KeyCode.LeftShift then
player.Character.Humanoid.WalkSpeed = walkSpeed
Animation:Stop()
end
end
userInput.InputBegan:Connect(beginSprint)
userInput.InputEnded:Connect(endSprint)
I am sorry, I made a veryyyyy small error, which breaks it . Here’s a fixed version of the script
local Character = script.Parent
local Humanoid = Character:WaitForChild("Humanoid")
local DefaultSpeed = game:GetService("StarterPlayer").CharacterWalkSpeed
local SprintSpeed = 30
local Animation = script:WaitForChild("Animation")
local AnimTrack = Humanoid:LoadAnimation(Animation)
local UserInputService = game:GetService("UserInputService")
local SprintKeyBind = Enum.KeyCode.LeftShift
UserInputService.InputBegan:Connect(function(Input, gameProcessed)
if not gameProcessed then
if Input.KeyCode == SprintKeyBind then
Humanoid.WalkSpeed = SprintSpeed
AnimTrack:Play()
end
end
end)
UserInputService.InputEnded:Connect(function(Input, gameProcessed)
if not gameProcessed then
if Input.KeyCode == SprintKeyBind then
Humanoid.WalkSpeed = DefaultSpeed
AnimTrack:Stop()
end
end
end)
game:GetService(“UserInputService”).InputBegan:Connect(function(input, gameProcessedEvent)
if input.KeyCode == Enum.KeyCode.LeftShift then
ShiftKeyDown = true
end
end)
game:GetService(“UserInputService”).InputEnded:Connect(function(input, gameProcessedEvent)
if input.KeyCode == Enum.KeyCode.LeftShift then
ShiftKeyDown = false
end
end)
game:GetService(“RunService”).RenderStepped:Connect(function(deltaTime)
if ShiftKeyDown then
local humanoid = game.Workspace:FindFirstChildOfClass(“Humanoid”)
if humanoid and humanoid.MoveDirection.magnitude > 0 then
local animationTrack = humanoid.AnimationController:LoadAnimation(YourAnimationId)
animationTrack:Play()
end
end
end)
This seemingly does not work, Just to confirm, StarterPlayerScripts, Animation object named “Animation” within a LocalScript with the id of 13510270711, No errors in the output, just holding shift doesn’t make the character move any faster and doesn’t change the animation.
Doesn’t work, StarterPlayerScripts, local script. Doesn’t make the character move any faster and doesn’t add the animation, also had to fix some incorrect quotes (quotes instead of apostrophes)
If this is not how your scripts should be utilised please inform me of how I can make it work,
Make the animation only play if the player is moving
local Character = script.Parent
local Humanoid = Character:WaitForChild("Humanoid")
local DefaultSpeed = game:GetService("StarterPlayer").CharacterWalkSpeed
local SprintSpeed = 30
local Animation = script:WaitForChild("Animation")
local AnimTrack = Humanoid.Animator:LoadAnimation(Animation)
local UserInputService = game:GetService("UserInputService")
local SprintKeyBind = Enum.KeyCode.LeftShift
local isMoving = false
UserInputService.InputBegan:Connect(function(Input, gameProcessed)
if not gameProcessed then
if Input.KeyCode == SprintKeyBind then
Humanoid.WalkSpeed = SprintSpeed
isMoving = true
end
end
end)
UserInputService.InputEnded:Connect(function(Input, gameProcessed)
if not gameProcessed then
if Input.KeyCode == SprintKeyBind then
Humanoid.WalkSpeed = DefaultSpeed
isMoving = false
AnimTrack:Stop()
end
end
end)
Humanoid.Running:Connect(function(speed)
if speed > 0 and isMoving then
AnimTrack:Play()
AnimTrack:AdjustSpeed(1) -- Set the animation speed to 1 (default speed)
AnimTrack.Looped = true -- Enable looping
elseif speed == 0 or not isMoving then
AnimTrack:Stop()
end
end)
I’m going to give you the solution to the post though, Thanks to everyone for the help!
