💖 SDL_RunHapticEffect(3) 💖

okay bestie, welcome to the SDL3 FUNCTIONS corner of the manual, where we make your controller go brrrrr on purpose 🫶 this one's about running a haptic effect on its associated haptic device. yes, that's the whole vibe. let's get into it.

✨ NAME ✨

SDL_RunHapticEffect — Run the haptic effect on its associated haptic device.

it's giving "push the go button on the buzz". iconic 💅

🌸 SYNOPSIS 🌸

#include <SDL3/SDL_haptic.h>

bool SDL_RunHapticEffect(SDL_Haptic *haptic, SDL_HapticEffectID effect, Uint32 iterations);

copy it exactly, no cap, don't freestyle the signature 🙈

🦋 DESCRIPTION 🦋

so here's the tea, bestie 🍓 there's two whole different ways to make a thing go forever, and the way that people mix them up is literally the classic haptic blunder.

  • Wanna repeat the effect over and over indefinitely? Set iterations to SDL_HAPTIC_INFINITY. This repeats the envelope — the attack and the fade. So every loop does the whole rise-and-fall thing again. 🔁
  • Wanna make one single instance of the effect last indefinitely, so the effect does not fade? Then instead set the effect's length in its structure/union to SDL_HAPTIC_INFINITY. one long smooth buzz, no envelope re-runs. 😌
these are two different knobs and they do two different things, so pick the one that matches the actual vibe you want. no guessing, bestie. 💀

🎀 FUNCTION PARAMETERS 🎀

  • haptic — the SDL_Haptic device to run the effect on. the main character device in question 👑
  • effect — the ID of the haptic effect to run. you gotta have an ID, fr fr.
  • iterations — the number of iterations to run the effect; use SDL_HAPTIC_INFINITY to repeat forever. ♾️ forever-ever? forever-ever. 💖

⭐ RETURN VALUE ⭐

Returns true on success or false on failure — and when it fails, call SDL_GetError() for more information. always check your return values, bestie, it's self care 🌈

💜 AVAILABILITY 💜

This function is available since SDL 3.2.0. if you're on anything older, it's simply not there and that's not a you problem, that's a version problem 🧚

🌟 SEE ALSO 🌟

go read those too, iykyk ✨

lowkey reminder: you can start effects, you can stop effects, you can even ask about their status. you're basically a haptic sommelier now. 🍷💅
