lovr.focus

Edit

The lovr.focus callback is called whenever the application acquires or loses focus (for example, when opening or closing the Steam dashboard). The callback receives a single argument, focused, which is a boolean indicating whether or not the application is now focused. It may make sense to pause the game or reduce visual fidelity when the application loses focus.

function lovr.focus(focused)
  -- your code here
end
