The whole clue is the definition (& lit or double definition).
How the clue works
This is a double definition where One engaged in break, perhaps whimsically describes a snooker player who pots during a break (a potter). The second part, to move with little energy, gives the verb POTTER, meaning to amble or dawdle about aimlessly.
