public class VirtualJoystick

Object
VirtualJoystick

An on-screen analog stick. Add one with TouchControls#addJoystick(float, float, float); the framework draws it and feeds its direction into GameInput, so the game reads it the same way whether the player uses touch or a keyboard:

as analog axes via GameInput#getAxisX() / GameInput#getAxisY() (each -1..1, with x pointing right and y pointing down the screen), and
as digital game actions: pushing the stick past its dead zone presses com.codename1.ui.Display#GAME_LEFT / GAME_RIGHT / GAME_UP / GAME_DOWN, so GameInput#isGameKeyDown(int) works unchanged.

Positions and sizes are in the GameView’s pixel coordinates (origin at the top left).
