_input events are always triggered

Moving the mouse out of the window will still trigger the InputEventMouseMotiont action.
Is there a setting or a way to avoid it?

You can simply handle only events you are interested in. For instance, if you need to capture only a left-click:

func _unhandled_input(event):
	if event is InputEventMouseButton and event.pressed and event.button_index == MOUSE_BUTTON_LEFT:
		# do your stuff

And ignore all mouse motion events.

The Window class has two events for this mouse_entered and mouse_exited:

Window

Listen for these events and you will know, if the mouse cursor is currently inside or outside of the window.

Thanks, because the building wants to follow the mouse movements, I need it.

Thanks, that’s what I wanted.
