💖 SDL_UpdateHapticEffect(3) 💖

okay so bestie, this is a page from the SDL3 FUNCTIONS manual, and it's about making your controller go brrrr but like, changing its mind mid-brrrr. let's get into it 🎀

✨ NAME ✨

SDL_UpdateHapticEffect — update the properties of an effect. like glow-up but for vibrations 💅

🌸 SYNOPSIS 🌸

#include <SDL3/SDL_haptic.h>

bool SDL_UpdateHapticEffect(SDL_Haptic *haptic, SDL_HapticEffectID effect, const SDL_HapticEffect *data);

🦋 DESCRIPTION 🦋

So you can use this dynamically, no cap — but the behavior when you're dynamically changing direction may be strange. Specifically: the effect may re-upload itself and start playing from the start. it's giving "surprise, we're back at zero" 😭

Also — and this is the important part, bestie — you cannot change the type either when running SDL_UpdateHapticEffect(). the type is locked in, periodt.

👑 FUNCTION PARAMETERS 👑

  • haptic — the SDL_Haptic device that has the effect. it's the one holding the vibe 💜
  • effect — the identifier of the effect to update. yes, the specific one, not all of them 🙈
  • data — an SDL_HapticEffect structure containing the new effect properties to use. this is the new fit you're putting it in ✨

💀 RETURN VALUE 💀

Returns true on success or false on failure — and if it's giving failure, call SDL_GetError() for more information. she will tell you what went wrong, fr fr.

🌈 AVAILABILITY 🌈

This function is available since SDL 3.2.0. so if you're on something older, bestie, it's not there. 🫶

🔥 SEE ALSO 🔥

that's the whole page, no notes 💖 this one's from Simple Directmedia Layer, SDL 3.4.18, and it's literally titled SDL_UpdateHapticEffect(3) if you need to find her again. go forth and update those effects, you icon 👑🌸
