# SDL_HINT_JOYSTICK_LINUX_DIGITAL_HATS A variable controlling whether joysticks on Linux will always treat 'hat' axis inputs (ABS_HAT0X - ABS_HAT3Y) as 8-way digital hats without checking whether they may be analog. ## Header File Defined in [<SDL3/SDL_hints.h>](https://github.com/libsdl-org/SDL/blob/main/include/SDL3/SDL_hints.h) ## Syntax ```c #define SDL_HINT_JOYSTICK_LINUX_DIGITAL_HATS "SDL_JOYSTICK_LINUX_DIGITAL_HATS" ``` ## Remarks The variable can be set to the following values: - "0": Only map hat axis inputs to digital hat outputs if the input axes appear to actually be digital. (default) - "1": Always handle the input axes numbered ABS_HAT0X to ABS_HAT3Y as digital hats. This hint should be set before a controller is opened. ## Version This hint is available since SDL 3.2.0. ---- [CategoryAPI](CategoryAPI), [CategoryAPIMacro](CategoryAPIMacro), [CategoryHints](CategoryHints)
