Developing virtual game controls
I think that one of the reasons why beat 'em up games have lost popularity on smartphones is the fact that there is no game pad to control the character's movements. Touchable screens have conditioned games to be played by using the accelerometer or handling touches; that's why it's not usual to find titles like the classic arcade games. In the case of existing games, their playability is not comparable to handling a joystick and beating almost-indestructible buttons.
Despite this, we can emulate game pads by designing some places on the screen to react to touches and convert them into movements and actions. These touchable areas must be well-defined to track fingers moving on them, so let's get to work and make our own controller.
We're going to create a separate class to specify the pad's behavior due to the amount of methods and variables we will need to manage:
