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
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
