SDL_HINT_JOY...NUX_DEADZONES(3)

💖 SDL_HINT_JOYSTICK_LINUX_DEADZONES 💖

okay bestie, welcome to the SDL3 FUNCTIONS section of the manual, page SDL_HINT_JOY...NUX_DEADZONES(3) 🎀 (yeah the title got squished by the terminal, we don't talk about it, it's giving budget cuts 💀). Today we're talking about one very specific little hint and honestly? she's niche but she matters.

---

✨ NAME ✨

SDL_HINT_JOYSTICK_LINUX_DEADZONES — a variable that controls whether joysticks on Linux stick to their HID-defined deadzones or just rawdog it and return unfiltered values. no cap. 🕹️

---

🌈 SYNOPSIS 🌈

pull her in like this, periodt:

#include <SDL3/SDL_hints.h>

#define SDL_HINT_JOYSTICK_LINUX_DEADZONES "SDL_JOYSTICK_LINUX_DEADZONES"

that #define is literally just the string "SDL_JOYSTICK_LINUX_DEADZONES" wearing a little macro costume 🧚 — character for character, don't get creative with it.

---

🦋 DESCRIPTION 🦋

so the variable takes these values, and there are exactly two of them, so no excuses:

• "0" — return unfiltered joystick axis values. this is the default, she's the main character whether you asked or not 👑
• "1" — return axis values with deadzones taken into account. the HID-defined ones. respectful. considerate. ate. 💅

⚠️ heads up babe: this hint should be set before a controller is opened. like, before. not during. not after. timing is everything and she is not flexible about it 😭

---

⭐ AVAILABILITY ⭐

this hint has been around since SDL 3.2.0. so if you're on something ancient, that's a you problem bestie 🙈

---

and that's the whole page, you're so welcome. 🫶

made with love by Simple Directmedia Layer — this is SDL 3.4.18, so you know it's fresh ✨ 💖🌸🦋
