Add support for Extended Gamepad controllers. What defines extended
gamepad controllers can be found here:
https://developer.apple.com/documentation/gamecontroller/gcextendedgamepad
Support has been added for controlling the pointer position using the
left thumbstick, left clicks using the A-button and right clicks using
the B-button. Also the Main menu can be accessed using the Home/Menu
button.
The thumbstick values are received when changed, however if holding the
thumbstick in the same position the valueChangedHandler will not be
called. Therefore store the X- and Y-axis values and begin to poll
readings of the stored values for as long as the thumbstick is out of
the center position.
Add support for mouses using the GameController framework. This requires
iOS 14 and up. The trackpad on the magic keyboard to iPads is connected
as a mouse and of course other connected mouses.
The mouse movements triggers calls to the mouseMovedHandler code
block. The calls delivers delta movements on the X and Y axis from the
last pointer position. It doesn't keep track on where the pointer is in
the view. That's where pointerPosition property in the iPhoneView comes
into place.
Move touch inputs to a TouchController class to move some logic from the
iPhoneView class. Only do this for touches on screen since connected
trackpads can generate touches as well. The latter ones are of type
UITouchTypeIndirectPointer while touches on screen are of type
UITouchTypeDirect. They are separated thanks to the preference key
UIApplicationSupportsIndirectInputEvents set to YES in Info.plist.
Without the preference above, there is no way to distinguish touches
from screen from a trackpad.
Add a GameController base class which handles user inputs from a
controller. The input is either a pointer move or a button action.
If the input is a pointer move, make sure that the move is within
valid coordinates in the game (respecting the resolution which is
most probably lower than the view resolution).
