al_install_haptic(3)

✨ NAME ✨

al_install_haptic — Allegro 5 API. Hiii bestie, welcome to the al_install_haptic(3) page in the Library Functions Manual 🫶 (source: the Allegro reference manual) — this one is short but lowkey important.

🎀 SYNOPSIS 🎀

#include <allegro5/allegro.h>

bool al_install_haptic(void)

💖 DESCRIPTION 💖

Okay so al_install_haptic installs the haptic (force feedback) device subsystem. Slay. You must call it before using any other haptic-related functions — like, that's the vibe check, no cap.

It returns true if the haptics subsystem could be initialized correctly, and false in case of error. Fr fr, check that return value.

For portability you should first open a display before calling al_install_haptic(3). On some platforms, such as DirectInput under Windows, al_install_haptic(3) will only work if at least one active display is available. And that display must stay available until al_uninstall_haptic(3) is called — the way that this is not optional, bestie 😭.

If you need to close and reopen your active display, for example, then you should call al_uninstall_haptic(3) before closing the display, and al_install_haptic(3) after opening it again. Periodt. ✨

🦋 SINCE 🦋

5.1.8 — she's been around, okay 👑

💀 [Unstable API]: Perhaps could be simplified due to limited support for all the exposed features across all of the platforms. Awaiting feedback from users.
