- * \file SDL_haptic.h
- *
- * \brief The SDL haptic subsystem allows you to control haptic (force feedback)
- * devices.
- *
- * The basic usage is as follows:
- * - Initialize the subsystem (::SDL_INIT_HAPTIC).
- * - Open a haptic device.
- * - SDL_HapticOpen() to open from index.
- * - SDL_HapticOpenFromJoystick() to open from an existing joystick.
- * - Create an effect (::SDL_HapticEffect).
- * - Upload the effect with SDL_HapticNewEffect().
- * - Run the effect with SDL_HapticRunEffect().
- * - (optional) Free the effect with SDL_HapticDestroyEffect().
- * - Close the haptic device with SDL_HapticClose().
- *
- * \par Simple rumble example:
- * \code
- * SDL_Haptic *haptic;
- *
- * // Open the device
- * haptic = SDL_HapticOpen( 0 );
- * if (haptic == NULL)
- * return -1;
- *
- * // Initialize simple rumble
- * if (SDL_HapticRumbleInit( haptic ) != 0)
- * return -1;
- *
- * // Play effect at 50% strength for 2 seconds
- * if (SDL_HapticRumblePlay( haptic, 0.5, 2000 ) != 0)
- * return -1;
- * SDL_Delay( 2000 );
- *
- * // Clean up
- * SDL_HapticClose( haptic );
- * \endcode
- *
- * \par Complete example:
- * \code
- * int test_haptic( SDL_Joystick * joystick ) {
- * SDL_Haptic *haptic;
- * SDL_HapticEffect effect;
- * int effect_id;
- *
- * // Open the device
- * haptic = SDL_HapticOpenFromJoystick( joystick );
- * if (haptic == NULL) return -1; // Most likely joystick isn't haptic
- *
- * // See if it can do sine waves
- * if ((SDL_HapticQuery(haptic) & SDL_HAPTIC_SINE)==0) {
- * SDL_HapticClose(haptic); // No sine effect
- * return -1;
- * }
- *
- * // Create the effect
- * memset( &effect, 0, sizeof(SDL_HapticEffect) ); // 0 is safe default
- * effect.type = SDL_HAPTIC_SINE;
- * effect.periodic.direction.type = SDL_HAPTIC_POLAR; // Polar coordinates
- * effect.periodic.direction.dir[0] = 18000; // Force comes from south
- * effect.periodic.period = 1000; // 1000 ms
- * effect.periodic.magnitude = 20000; // 20000/32767 strength
- * effect.periodic.length = 5000; // 5 seconds long
- * effect.periodic.attack_length = 1000; // Takes 1 second to get max strength
- * effect.periodic.fade_length = 1000; // Takes 1 second to fade away
- *
- * // Upload the effect
- * effect_id = SDL_HapticNewEffect( haptic, &effect );
- *
- * // Test the effect
- * SDL_HapticRunEffect( haptic, effect_id, 1 );
- * SDL_Delay( 5000); // Wait for the effect to finish
- *
- * // We destroy the effect, although closing the device also does this
- * SDL_HapticDestroyEffect( haptic, effect_id );
- *
- * // Close the device
- * SDL_HapticClose(haptic);
- *
- * return 0; // Success
- * }
- * \endcode

- * - ::SDL_HAPTIC_CARTESIAN : Specified by cartesian coordinates.
- * - ::SDL_HAPTIC_SPHERICAL : Specified by spherical coordinates.
- *
- * Cardinal directions of the haptic device are relative to the positioning
- * of the device. North is considered to be away from the user.
- *
- * The following diagram represents the cardinal directions:

- \endverbatim
- *
- * If type is ::SDL_HAPTIC_POLAR, direction is encoded by hundredths of a
- * degree starting north and turning clockwise. ::SDL_HAPTIC_POLAR only uses
- * the first \c dir parameter. The cardinal directions would be:
- * - North: 0 (0 degrees)
- * - East: 9000 (90 degrees)
- * - South: 18000 (180 degrees)
- * - West: 27000 (270 degrees)
- *
- * If type is ::SDL_HAPTIC_CARTESIAN, direction is encoded by three positions
- * (X axis, Y axis and Z axis (with 3 axes)). ::SDL_HAPTIC_CARTESIAN uses
- * the first three \c dir parameters. The cardinal directions would be:
- * - North: 0,-1, 0
- * - East: 1, 0, 0
- * - South: 0, 1, 0
- * - West: -1, 0, 0
- *
- * The Z axis represents the height of the effect if supported, otherwise
- * it's unused. In cartesian encoding (1, 2) would be the same as (2, 4), you
- * can use any multiple you want, only the direction matters.
- *
- * If type is ::SDL_HAPTIC_SPHERICAL, direction is encoded by two rotations.
- * The first two \c dir parameters are used. The \c dir parameters are as
- * follows (all values are in hundredths of degrees):
- * - Degrees from (1, 0) rotated towards (0, 1).
- * - Degrees towards (0, 0, 1) (device needs at least 3 axes).
- *
- *
- * Example of force coming from the south with all encodings (force coming
- * from the south means the user will have to pull the stick to counteract):
- * \code
- * SDL_HapticDirection direction;
- *
- * // Cartesian directions
- * direction.type = SDL_HAPTIC_CARTESIAN; // Using cartesian direction encoding.
- * direction.dir[0] = 0; // X position
- * direction.dir[1] = 1; // Y position
- * // Assuming the device has 2 axes, we don't need to specify third parameter.
- *
- * // Polar directions
- * direction.type = SDL_HAPTIC_POLAR; // We'll be using polar direction encoding.
- * direction.dir[0] = 18000; // Polar only uses first parameter
- *
- * // Spherical coordinates
- * direction.type = SDL_HAPTIC_SPHERICAL; // Spherical encoding
- * direction.dir[0] = 9000; // Since we only have two axes we don't need more parameters.

- * A periodic effect consists in a wave-shaped effect that repeats itself

- * - 27000: Displaced 75% of its period.

- * Button triggers may not be supported on all devices, it is advised to not
- * use them if possible. Buttons start at index 1 instead of index 0 like
- * the joystick.
- *
- * If both attack_length and fade_level are 0, the envelope is not used,
- * otherwise both values are used.
- *
- * Common parts:
- * \code
- * // Replay - All effects have this
- * Uint32 length; // Duration of effect (ms).
- * Uint16 delay; // Delay before starting effect.
- *
- * // Trigger - All effects have this
- * Uint16 button; // Button that triggers effect.
- * Uint16 interval; // How soon before effect can be triggered again.
- *
- * // Envelope - All effects except condition effects have this
- * Uint16 attack_length; // Duration of the attack (ms).
- * Uint16 attack_level; // Level at the start of the attack.
- * Uint16 fade_length; // Duration of the fade out (ms).
- * Uint16 fade_level; // Level at the end of the fade.
- * \endcode
- *
- *
- * Here we have an example of a constant effect evolution in time:
- * \verbatim
- Strength
- ^
- |
- | effect level --> _________________
- | / \
- | / \
- | / \
- | / \

- |
- +--------------------------------------------------> Time
- [--] [---]
- attack_length fade_length
-
- [------------------][-----------------------]
- delay length
- \endverbatim
- *
- * Note either the attack_level or the fade_level may be above the actual
- * effect level.
