Patterns for shore fishermen are especially hard to piece together. On a boat, electronics help a lot with pinpointing specifics. Your lure tells you a lot too. Just some questions to ask yourself are, what's the water temperature, what's the bottom composition like, did I get bit hopping the bait across the bottom or did I get hit on a slow drag, was I bit on the fall, when the bait was sitting still, or when the bait was moving?
Most of bass fishing is figuring out the spot within the spot concept. For example, say you are slow dragging a jig along the sides of a point and you get bit. Right before you got bit, you noticed that the bottom changed from chunk rock to sand. Being a smart angler, you start focusing on the structure change along the sides of the point at the depth where you got bit. You don't get another bite though, and wonder what happened. Thinking back, you remember that you pulled a strand of aquatic plant life off your jig when you were unhooking the bass. Then you start focusing on aquatic weed beds off points right next to a transition change from chunk rock to sand and the bass start coming into the boat.
Very rarely will you be able to dial in on a pattern with the very first fish you catch lie in the example, but after 2 or 3 you should be starting to have an idea. In reality, you'd have to try a few different types of lures and take water conditions into account too like clarity, temperature, and current before you got your first bite. Dragging a black and blue jig on the bottom when bass are boiling on shad probably isn't the best idea. The bass can sometimes tell you what lure to use too. If they have red gums and ground down teeth then they've been eating crayfish, and if their teeth are still noticeable and there's no red then they've been eating a lot of shad or other baitfish. Seeing bass attack bluegills or each other is a good hint too.
Hope this helps a it, and keep in mind what I wrote is a very simplified version of reading conditions and patterning bass. You can find an endless amount of information in magazines, online, books, and sometimes videos that all try to decipher the habits of the glorified, gigantic sunfish we call largemouth bass.
