Crossy Road - Side Scroller Example tap once to move blueprint

HI im working on a Crossy road type game where the player will have to repeatedly tap the move forward key and swipe to turn, I am using the 3d side scroller example template . Anyone know how to modify the side scroller character blueprint so that when the player taps once or presses the move key the actor runs one pace and the player player has to tap continuously to keep the character running?
