public class VirtualButton
- Object
- VirtualButton
An on-screen touch button. Add one with TouchControls#addButton(int, float, float, float); while a finger is on it the framework holds down the key code it
is mapped to, so GameInput#isKeyDown(int) and GameInput#wasKeyPressed(int)
report it exactly as a hardware key. Map it to a game action with
com.codename1.ui.Display#getKeyCode(int) (e.g.
Display.getInstance().getKeyCode(Display.GAME_FIRE)) or to any key code of your
own.
The position and radius are in the GameView’s pixel coordinates.
