Scenes are where the gameplay takes place in a game. Scenes control the story flow and usually include a prologue, title screen, menu screen, levels, and credits. Scenes contain tiles, layers, coordinates, and boundaries. Tiles make up the terrain, layers determine drawing order, coordinates specify position, and boundaries restrict the game area. The camera follows and zooms onto the player. Text is drawn using fonts and the heads-up display draws information like health permanently on the screen. Timers can be created to track elapsed time by incrementing a variable each second in a draw event.
