Flowcharts are used in games development to show the sequence of events and flow of control in a game. They use standard symbols like boxes, circles and arrows to represent actions, questions, and the path of gameplay. For example, a flowchart was made for the game Crazy Taxi to map out its core gameplay loop, helping the developers ensure the correct sequence of pick-ups, drop-offs, and other events. Flowcharts are a useful tool for planning and testing the logic and flow of a game from start to finish.
