I don't know what the circle in the image below used for changing directions and movements of a character is called. Can anyone provide me anything related to it? I want to include it in my game.

This screenshot is from game 'missiles'

It's a virtual joystick.

Whether or not you should use one as a controller is debatable, as discussed here.

  • You can't see/feel where the joystick is pointing when you are using it.
  • You can't feel where the 'edge' of the joystick is - meaning, you can't know when you are reaching the maximum in any direction
  • You don't always know when you're pressing the joystick. You can accidentally miss pressing it and not know, because you can't feel
    the joystick under your finger.
