Description gmesmer 2020-08-14 17:29:19 UTC 
Whenever polling SDL_JoystickGetHat, all inputs can be seen (numbers 0 to 9) except LEFTDOWN (number 5). When visibly holding LEFTDOWN on Hat 1, calling SDL_JoystickGetHat reports eiter down (1) or left (2) and cycles between these two on a repeatable basis. The controller is sending those values over as seen in other libraries (html based applications, sdl2, etc). 

Using the alterative SDL_PollEvent with SDL_JOYHATMOTION does report LEFTDOWN so there is an issue with the function SDL_JoystickGetHat.
Comment 1 gmesmer 2020-08-14 18:04:24 UTC 
new info, actually down is (4) and left is (8) while LEFTDOWN reports as (12121212 repeated)
Comment 2 gmesmer 2020-08-14 18:11:08 UTC 
Actually the LEFTDOWN reports as 12 (twelve) instead of 5

What controller and version of OS are you using?

> What controller and version of OS are you using?

this is using a nintendo switch pro controller (though it can be replicated on other controllers in my testing)

ubuntu 18.04.1 LTS arm64
should be using sdl1.2 from the latest apt package provided
Comment 5 Sam Lantinga 2021-01-08 07:00:04 UTC 
SDL 1.2 is no longer supported. Please let me know if you see this with SDL 2.0.
