How to make a Shift to Sprint system in ROBLOX studio (2024)

in this video, I will be teaching you on how to make a shift to sprint script in ROBLOX studio
script:
local UserInputService = game:GetService("UserInputService")
local RunService = game:GetService("RunService")
local player = game.Players.LocalPlayer
local character = player.Character or player.CharacterAdded:Wait()
local humanoid = character:WaitForChild("Humanoid")
local isRunning = false
local canRun = true
local function startRunning()
if canRun then
isRunning = true
humanoid.WalkSpeed = 30
end
end
local function stopRunning()
isRunning = false
humanoid.WalkSpeed = 16
end
local function handleRun(input)
if input.KeyCode == Enum.KeyCode.LeftShift then
if input.UserInputState == Enum.UserInputState.Begin then
startRunning()
elseif input.UserInputState == Enum.UserInputState.End then
stopRunning()
end
end
end
UserInputService.InputBegan:Connect(handleRun)
UserInputService.InputEnded:Connect(handleRun)
while RunService.RenderStepped:Wait() do
if isRunning then
wait(10)
stopRunning()
canRun = false
wait(4)
canRun = true
end
end

[@BrookDude]

local UserInputService = game:GetService("UserInputService")
local RunService = game:GetService("RunService")
local player = game.Players.LocalPlayer
local character = player.Character or player.CharacterAdded:Wait()
local humanoid = character:WaitForChild("Humanoid")
local isRunning = false
local canRun = true
local function startRunning()
if canRun then
isRunning = true
humanoid.WalkSpeed = 30
end
end
local function stopRunning()
isRunning = false
humanoid.WalkSpeed = 16
end
local function handleRun(input)
if input.KeyCode == Enum.KeyCode.LeftShift then
if input.UserInputState == Enum.UserInputState.Begin then
startRunning()
elseif input.UserInputState == Enum.UserInputState.End then
stopRunning()
end
end
end
local function setupCharacter(character)
humanoid = character:WaitForChild("Humanoid")
UserInputService.InputBegan:Connect(handleRun)
UserInputService.InputEnded:Connect(handleRun)
isRunning = false
canRun = true
end
setupCharacter(character)
player.CharacterAdded:Connect(function(newCharacter)
setupCharacter(newCharacter)
end)
RunService.RenderStepped:Connect(function()
if isRunning then
wait(10)
stopRunning()
canRun = false
wait(4)
canRun = true
end
end)
