How to Use the Android platform to develop FPS games? What are the implementation methods and what are the differences between these methods? First, let's first understand what FPS is.

English name: FPS (First Personal Shooting)

The first-person perspective shooting game, as its name implies, is a shooting game from the player's subjective perspective. Players no longer manipulate virtual characters on the screen like other games, but experience the visual impact of the game in an immersive manner, which greatly enhances the initiative and realism of the game.
