al_set_haptic_autocenter(3alleg5)

💖 NAME 💖

al_set_haptic_autocenter — okay so this is the Allegro 5 API, and this function is the one that tells your haptic device whether it should snap itself back to center, bestie. ✨

---

✨ SYNOPSIS ✨

#include <allegro5/allegro.h>

bool al_set_haptic_autocenter(ALLEGRO_HAPTIC *hap, double intensity)

---

🎀 DESCRIPTION 🎀

So basically, this turns the automatic centering feature of your haptic device on or off — but only if the device actually supports it, no cap. 🫶

Depending on what device you're working with, auto-centering may make sure that the axes of the device get centered again automatically after a haptic effect has finished playing. Like, it tidies itself up. Iconic behavior honestly.

The intensity parameter is a double and you should pass it something between 0.0 and 1.0:

• 0.0 — automatic centering is disabled, periodt
• 1.0 — full strength automatic centering
• anything in between those two extremes — you get partial automatic centering

⚠️ Okay important thing though: some platforms do not support partial automatic centering. So if you're on one of those, the rules change and it's giving binary: - a value less than 0.5 turns it off - a value equal to or higher than 0.5 turns it on

Returns true if it was set successfully, false if not. Simple as that. 💅

Here's the catch though — this can only work if al_get_haptic_capabilities(3alleg5) returns a value that has ALLEGRO_HAPTIC_AUTOCENTER from ALLEGRO_HAPTIC_CONSTANTS(3alleg5) set. If it doesn't? This function returns false. That's it, that's the whole vibe check. 😭

5.1.9

👑 [Unstable API]: Perhaps could be simplified due to limited support for all the exposed features across all of the platforms. Awaiting feedback from users. (yes bestie they're literally asking for your thoughts, go tell them 🌸)
