A structure containing a template for a ramp effect.
Usage
#include "SDL3/SDL.h"
typedef struct SDL_HapticRamp { /* Header */ Uint16 type; /**< SDL_HAPTIC_RAMP */ SDL_HapticDirection direction; /**< Direction of the effect. */ /* Replay */ Uint32 length; /**< Duration of the effect. */ Uint16 delay; /**< Delay before starting the effect. */ /* Trigger */ Uint16 button; /**< Button that triggers the effect. */ Uint16 interval; /**< How soon it can be triggered again after button. */ /* Ramp */ Sint16 start; /**< Beginning strength level. */ Sint16 end; /**< Ending strength level. */ /* Envelope */ Uint16 attack_length; /**< Duration of the attack. */ Uint16 attack_level; /**< Level at the start of the attack. */ Uint16 fade_length; /**< Duration of the fade. */ Uint16 fade_level; /**< Level at the end of the fade. */ } SDL_HapticRamp;

Overview
This struct is exclusively for the SDL_HAPTIC_RAMP
effect.
The ramp effect starts at start strength and ends at end strength. It augments in linear fashion. If you use attack and fade with a ramp the effects get added to the ramp effect making the effect become quadratic instead of linear.
