WindowFocusReleased

Unsafe

For thread safety, this property is not safe to read in an unsynchronized thread.

Event of:

Description:

The UserInputService WindowFocusReleased event fires when the window of the Roblox client loses focus - typically when the Roblox client is minimized by the user.

For example, the code below prints “Window focus released” whenever the Roblox client loses focus.

local UserInputService = game:GetService("UserInputService")

UserInputService.WindowFocusReleased:Connect(function()
	print("Window focus released")
end)

This event can be used alongside UserInputService/WindowFocused to track whether the Roblox client is actively focused on a user’s screen.

Since it only fires locally, it can only be used in a LocalScript.

Code Samples

Window Focus AFK Script

This example fires a RemoteEvent/FireServer|RemoveEvent to the server name AfkEvent when the LocalPlayer’s client gains or loses focus.

The purpose of this code sample is to fire a server-side event to indicate when the player is AFK. This is indicated by spawning a ForceField around the player when the client loses focus and Instance/Destroy|destroying the forcefield when the client gains focus.

In order for this example to work as expected, the code labelled LocalScript must be placed in a LocalScript and the code labelled Script must be placed in a Script.
