Constant SDL_HINT_JOYSTICK_LINUX_DIGITAL_HATS

pub const SDL_HINT_JOYSTICK_LINUX_DIGITAL_HATS: *const i8 = _; // {alloc39683<imm>: *const i8}
Available on crate feature dep_sdl3 only.
Expand description

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.

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.

§Availability

This hint is available since SDL 3.2.0.
