InputJoystick
InputJoystick[] _EventObject
creates and instance of 2D manipulator (virtual joystick)
Event generation
It fires an event with {x_, y_} coordinates of a joystick in a range of [-1,1] once it has been dragged by a user.
Helpers
There is helper function to integrate the position, that joystick controls velocity instead of absolute position
InputJoystick`IntegrationHelper[initialValue_:{0,0}, delta_:0.01][callback_Function] _Function
for example
cell 1
pt = {0.,0.};
handler = InputJoystick`IntegrationHelper[][Function[xy,
pt = xy
]];
EventHandler[InputJoystick[], handler]
cell 2
Graphics[
{Red, PointSize[0.05], Point[pt // Offload]}
, PlotRange->{{-1,1}, {-1,1}}
]
Chaining events
One can reuse another event
InputJoystick[event_EventObject, rest___]
