IsKeyDown

UserInputService

This function returns whether the user is holding down the key associated with the given Enum/KeyCode. It returns true if the specified key is pressed or false if it is not pressed.

This can be used to check if a specific key, such as the space bar, is being pressed. For example:

local UserInputService = game:GetService("UserInputService")

local spaceHeld = UserInputService:IsKeyDown(Enum.KeyCode.Space)

To retrieve a list of all keys pressed by the user, use the UserInputService/GetKeysPressed function.

Since UserInputService is client-side only, this function can only be used in a LocalScript.

This example uses the UserInputService/IsKeyDown function to create different behaviors when a shift key is held down than when a shift key is not held down when user input UserInputBegan|begins.

The local function IsShiftKeyDown() returns whether the left or right shift Enum/KeyCode/keys are pressed.
