| Interactive animation: Virtual joystick Description There are many ways you can create interactive motion with Macromedia Flash. This sample demonstrates how you can create a virtual joystick that controls the motion of a symbol. It also demonstrates how a draggable symbol (the joystick knob) can be constrained to the area of a circle. Furthermore, the joystick knob behaves as if there is spring tension when it is released. Key features and ActionScript elements Draggable symbols, Math object, Object object, localToGlobal, with Instructions Drag the joystick knob away from the center to control the motion of the beetle. The farther you pull the joystick the faster the beetle will move. The source file for this movie (movement-joystick.fla) can be found in the Flash MX/Samples folder.
