SDL_JoystickGetAxis(3)

💖 SDL_JoystickGetAxis(3) 💖

okay bestie, welcome to the SDL API Reference — this is the one where we go poke a joystick and ask it "hey girl, where's that axis at rn?" 🕹️✨

🌸 NAME 🌸

SDL_JoystickGetAxis — get the current state of an axis 💅

---

✨ SYNOPSIS ✨

#include "SDL.h"

Sint16 SDL_JoystickGetAxis(SDL_Joystick *joystick, int axis);

---

🦋 DESCRIPTION 🦋

so SDL_JoystickGetAxis returns the current state of the given axis on the given joystick. that's it, that's the whole vibe. you hand it a joystick, you hand it an axis number, it tells you where that axis is right now. periodt. 💅

on most modern joysticks, the X axis is usually represented by axis 0 and the Y axis by axis 1. iconic. the value that comes back from SDL_JoystickGetAxis is a signed integer (-32768 to 32768) representing the current position of the axis. lowkey important: it maybe necessary to impose certain tolerances on these values to account for jitter — like, the axis is a lil shaky, it's not being dramatic on purpose, it's just jittery. give it some grace. 🫶

and it's worth noting that some joysticks use axes 2 and 3 for extra buttons. so if you're out here like "why is axis 2 doing THAT" — it's not an axis bestie, it's a button in a trench coat. 😭

💜 RETURN VALUE 💜

returns a 16-bit signed integer representing the current position of the axis. no cap. 🌟

🎀 EXAMPLES 🎀

Sint16 x_move, y_move;
SDL_Joystick *joy1;
.
.
x_move=SDL_JoystickGetAxis(joy1, 0);
y_move=SDL_JoystickGetAxis(joy1, 1);

fr fr, remember: axis 0 is X, axis 1 is Y, and the jitter is real so be nice about your tolerances. 💀
