Any movement in the water causes water molecules to collide. This causes pressure waves that act like ripples in the water. These pressure waves are detected by the lateral line. Bass prefer to hunt by sight but at night the lateral line becomes a major player. I have caught hundreds of bass at night with a jig ( w/ rattles) A spinnerbait can be awesome at night as well. Soft plastics that push alot of water like the Rage series, Lake Fork Hyper series, Zoom Dead Ringer and Brush Hog can be deadly. Boot tail or paddle tail swimbaits can shine also. I would not rely on topwater. It has its time, but has too many limitations. When the thermocline sets up, you can actually incorporate deep diving cranks into your arsenol. Dont get caught up in lunar phases. I have over 200 night trips under my belt and have caught them on all phases. The moon does help provide a silloutte for over head presentations, but anytime you can get out is a good time. Fish will transition from vegetation to wood soon if there is an abundance of it, so dont get caught up in one single pattern. Some bodies of water fish better than others at night as well. Oh hey, try swimming a jig with the lower half of a Stanley Ribbit Frog. Use a light VERY SPARINGLY. I am out of time. Good luck.
