Joe 2009-11-23 21:31:10 PST If type is ::SDL_HAPTIC_CARTESIAN, direction is encoded by three positions 367 * (X axis, Y axis and Z axis (with 3 axes)). ::SDL_HAPTIC_CARTESIAN uses 368 * the first three \c dir parameters. The cardinal directions would be: 369 * - North: 0,-1, 0 370 * - East: -1, 0, 0 371 * - South: 0, 1, 0 372 * - West: 1, 0, 0 typedef struct SDL_HapticDirection { Uint8 type; /**< The type of encoding. */ Uint16 dir[3]; /**< The encoded direction. */ } SDL_HapticDirection; An unsigned int can't store negative values and I don't see an alternate way to encode them in the docs or source. The best I have been able to come up with is using a negative magnitude for the effect but this will only get me 2 of the 4 quadrants in the plane for 2d effects. I looked at the win32 and linux implementations and I believe is is safe to use signed ints in the direction struct. I am unfamiliar with the darwin haptics API so I don't know if it is safe.

1.3 release checklist:
 * Create jobs@libsdl.org
 * Implement landscape mode for iPhone port
 * Add higher precision timers for profiling
 * Implement YUV texture support
   - in progress, software support is done, Ryan is working on OpenGL shaders
 * Implement desktop video mode change notification?
 * Add OpenGL 3.0 context support
 * Finish multiple display support
 * Open windows on display that is selected when creating a window
 * Create testing plan - becoming more and more important...
   - unit tests for each feature and combination with expected output
     and actual output comparison.
 * Public license for SDL_compat.c, tests, and SDL_main*
 * Verify mouse grab support
 * Properly handle mouse grab with Vista DPI scaling
 * Make sure the mouse is where it's supposed to be when un-grabbed
 * Plan how to handle events on foreign windows
 * Add keyboard enumeration / name query API
 * Implement NET_WM_PING and NET_WM_PID/WM_CLIENT_MACHINE (?)
   - http://standards.freedesktop.org/wm-spec/wm-spec-1.3.html#KILLINGWINDOWS
 * Add a timeout parameter for SDL_WaitEvent() (?)
   - http://lists.libsdl.org/pipermail/sdl-libsdl.org/2008-May/thread.html#65067
 * Implement key repeat at the driver level
 * Add name -> keysym and name -> scancode lookup functions
 * Fix building haptic system on win32
 * Add always on top window styles
 * Add video modes that have an alpha channel?
 * Implement SDL_RenderReadPixels() for screenshots and automated testing
 * Create extended set of (negative) error codes and have the API functions document and return them.
 * Add clipboard support (from scrap demo)
 * Add support for desktop windows?
 * Add support for synchronizing 2D updates with vblank (bug #406)
 * Add support for real-time threads and/or adjusting thread priority?
 * Add support for querying the number of CPUs and binding threads to them?
 * Allow setting multiple icon sizes

Wish list for the 1.3 development branch:
http://bugzilla.libsdl.org/

 * Add a way to register custom events
 * DirectInput joystick support needs to be implemented
 * Explicit vertical retrace wait (maybe separate from SDL_Flip?)
 * Shaped windows, windows without borders
 * Multiple display support
 * Add a timestamp to events
 * Add audio input API
 * Add modifier state to key and button events

In the jump from 1.2 to 1.3, we should change the SDL_Rect members to
int and evaluate all the rest of the datatypes.  This is the only place
we should do it though, since the 1.2 series should not break binary
compatibility in this way.

Requests:
 * PCM volume control (deprecated, but possible)
