poll_joystick(3alleg4)

✨ poll_joystick — the Allegro manual page, bestie edition ✨

okay so this is poll_joystick(3alleg4) from the Allegro manual (yes the game programming library, the icon, the moment) and we're gonna get you fluent in it 💖

🎀 NAME 🎀

poll_joystick — polls the joystick. Allegro game programming library. that's it, that's the job, and it does it flawlessly 💅

🦋 SYNOPSIS 🦋

#include <allegro.h>

int poll_joystick();

🌸 DESCRIPTION 🌸

okay so here's the tea: the joystick handler is not interrupt driven. like, at all. it's not gonna tap you on the shoulder when something happens. so you have to call this function every now and again to update the global position values. it's giving "you text first" energy fr fr 😭

here's the example, verbatim, do not touch:

do {
   /* Get joystick input */
   poll_joystick();

   /* Process input for the first joystick */
   if (joy[0].button[0].b)
      first_button_pressed();

   if (joy[0].button[1].b)
      second_button_pressed();
   ...
} while(!done);

see how it's just vibing in a loop? that's the whole strategy. poll, check, repeat. main character energy tbh 👑

⭐ RETURN VALUE ⭐

returns zero on success 🫶 or a negative number on failure — and the failure is usually because no joystick driver was installed. so if you're getting negatives, check your driver situation before you spiral, bestie 💀
