SDL_HapticRamp(3type)

✨ SDL_HapticRamp ✨

okay bestie, welcome to the SDL_HapticRamp page 💖 this one lives in the SDL3 datatypes corner of the manual (yes, manual page SDL_HapticRamp(3type), we see you) and it's literally just a struct. a little baby struct. a template. for a Ramp effect. and honestly? it ate.

🌸 NAME 🌸

SDL_HapticRamp — a structure containing a template for a Ramp effect. that's it, that's the whole job, no notes 🎀

---

🦋 SYNOPSIS 🦋

#include <SDL3/SDL_haptic.h>

typedef struct SDL_HapticRamp
{
    /* Header */
    SDL_HapticEffectType 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;

like look at her. every field labeled. every field commented. she's organized. she's giving main character energy 👑

💅 DESCRIPTION 💅

so this struct is exclusively for the SDL_HAPTIC_RAMP effect. exclusive!! no other effect may sit with her, she does not share 💀

the ramp effect starts at start strength and ends at end strength. it augments in linear fashion — a nice little straight line of vibes going from one strength to the other, no cap.

but here's the tea: if you use attack and fade with a ramp, the effects get added to the ramp effect, which makes the effect become quadratic instead of linear. not a straight line anymore bestie, it's a curve now. it's giving parabola 🌈

⭐ AVAILABILITY ⭐

this struct is available since SDL 3.2.0. she's not ancient, she's not brand new, she's just right 🫶
