🦋 DESCRIPTION 🦋

so the index you pass in as an argument? it refers to the N'th haptic device on this system. N'th. like, the one at that spot in the lineup. periodt ✨

and here's the tea when you actually open a haptic device: its gain gets set to maximum and autocenter gets disabled. that's just what happens, not a vibe you chose. if you wanna change those values, you use SDL_SetHapticGain() and SDL_SetHapticAutocenter(). iykyk 💖
