Hi Gardian,
So firstly, your reply has been very insightful so thank you for the very detailed response it has deepend my understanding.
I’m using enhanced input because i’m in 5.2/
I have a mouse click event within the widget (to spawn a mesh ghost) and then a second in the controller (to spawn the mesh and then immediately close the function)
I understand and I haven’t actually tried to utilise the flipflop node. Ill try to implement what you have told me 
Thank you again
