SDL_HINT_JOY...HAT_DEADZONES(3)

๐Ÿ’– SDL_HINT_JOYSTICK_LINUX_HAT_DEADZONES(3) ๐Ÿ’–

okay so this is a page from the SDL3 FUNCTIONS manual, and bestie, we're talking about a hint โ€” one of those lil vibe-setting variables that tells SDL how to behave. This one's the whole SDL_HINT_JOYSTICK_LINUX_HAT_DEADZONES situation, and no cap it's more interesting than it sounds. ๐ŸŽฎโœจ


๐ŸŒธ NAME ๐ŸŒธ

SDL_HINT_JOYSTICK_LINUX_HAT_DEADZONES โ€” a variable that controls whether digital hats on Linux apply deadzones to their underlying input axes, or just rawdog it with unfiltered values. ๐Ÿ•น๏ธ


โœจ SYNOPSIS โœจ

like, here's how you even get to it:

#include <SDL3/SDL_hints.h>

#define SDL_HINT_JOYSTICK_LINUX_HAT_DEADZONES "SDL_JOYSTICK_LINUX_HAT_DEADZONES"

so iconic. the macro literally is the string, iykyk. ๐Ÿ’…


๐Ÿฆ‹ DESCRIPTION ๐Ÿฆ‹

okay so the variable can be set to these values, and you gotta pick one:

  • "0" โ€” return digital hat values based on unfiltered input axis values. no deadzone, no filtering, just the raw truth. ๐Ÿซฃ
  • "1" โ€” return digital hat values with deadzones on the input axes taken into account. this one's the default, so if you don't say anything, this is what you get. ๐Ÿ‘‘
lowkey important: this hint should be set before a controller is opened. like, before. not after. timing is everything bestie, the way that hints work is they gotta be in place first. ๐Ÿ˜ญ

๐ŸŒˆ AVAILABILITY ๐ŸŒˆ

this hint has been around since SDL 3.2.0, so it's been serving looks for a minute. โญ


and that's the whole page, fr fr โ€” every option, every default, every "set it before you open a controller," all of it. nothing skipped, nothing invented, just the facts with a lil sparkle on top. ๐ŸŽ€

this lil love letter came to you from Simple Directmedia Layer, rocking version SDL 3.4.18. mwah, go forth and deadzone responsibly ๐Ÿ’–๐Ÿงšโ€โ™€๏ธ๐Ÿฆ‹
