* # CategoryHaptic
*
* 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().
*
* Simple rumble example:
*
* ```c
* 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 );
* ```
*
* Complete example:
*
* ```c
* 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
* SDL_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
* }
* ```

* Structure that represents a haptic direction.
*
* This is the direction where the force comes from, instead of the direction

*
* Directions can be specified by:
*
* - SDL_HAPTIC_POLAR : Specified by polar coordinates.
* - 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:
*
* ```
* .--.
* |__| .-------.
* |=.| |.-----.|
* |--| || ||
* | | |'-----'|
* |__|~')_____('
* [ COMPUTER ]
*

* |
* |
* v
* South (0,1)
*
*
* [ USER ]
* \|||/
* (o o)
* ---ooO-(_)-Ooo---
* ```
*
* 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
* `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 `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 `dir` parameters are used. The `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):
*
* ```c
* 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 over

*
* - 0: No phase displacement.
* - 9000: Displaced 25% of its period.
