Why is my shift to sprint script not working?

Help and Feedback Scripting Support
#1

Im not getting any errors, and I don’t know why it’s not working.

local UIS = game:GetService("UserInputService")

local Humanoid = script.Parent:FindFirstChildOfClass("Humanoid")

if UIS:IsKeyDown(Enum.KeyCode.LeftShift) == true then
	Humanoid.WalkSpeed = 25
else
	Humanoid.WalkSpeed = 16
end

You have to connect UIS to InputBegan for it to start.

UserInputService.InputBegan:Connect(function(input, gameProcessed)
    if gameProcessed then return end
    if input.KeyCode == Enum.KeyCode.LeftShift then
        print("Speed Boost Here")
        Humanoid.WalkSpeed = 25
    end
end)

The same can be done with InputEnded to make the speed go back to normal.

UserInputService.InputEnded:Connect(function(input, gameProcessed)
    if gameProcessed then return end
    if input.KeyCode == Enum.KeyCode.LeftShift then
        Humanoid.WalkSpeed = 16
    end
end)

I think you need to get the function of the Input as Schkr1 said.

Do I use this in a script? because its not working?

Yes, so you do use this in a script. You would have to make two separate functions to get the detection for when LeftShift is inputted and then increase the speed, then get the detection for when LeftShift is not inputted anymore and then return the player’s speed back to normal. Using an if else statement in your case wouldn’t exactly work unfortunately. Hope this somewhat helps.

For example

local UIS = game:GetService("UserInputService")

local Players = game:GetService("Players")
local player = Players.LocalPlayer

UIS.InputBegan:Connect(function(input, gameProcessed) -- starts sprinting
	if not gameProcessed then
		if input.KeyCode == Enum.KeyCode.LeftControl then
			player.Character.Humanoid.WalkSpeed = 25
		end
	end
end)

UIS.InputEnded:Connect(function(input, gameProcessed) -- no longer starts sprinting
	if not gameProcessed then
		if input.KeyCode == Enum.KeyCode.LeftControl then
			player.Character.Humanoid.WalkSpeed = 16
		end
	end
end)

conditional statements dont run as triggers and they run straight they wont gonna wait the condition
