SDL_SetJoystickVirtualButton(3)

๐Ÿ’– SDL_SetJoystickVirtualButton(3) ๐Ÿ’–

okay bestie, welcome to the SDL3 FUNCTIONS section of the manual, and lemme tell you, this one is a whole vibe. it's all about poking the buttons on a virtual joystick you made yourself. iconic behavior honestly ๐ŸŽฎโœจ


โœจ NAME โœจ

SDL_SetJoystickVirtualButton โ€” set the state of a button on an opened virtual joystick, fr fr.


๐ŸŒธ SYNOPSIS ๐ŸŒธ

#include <SDL3/SDL_joystick.h>

bool SDL_SetJoystickVirtualButton(SDL_Joystick *joystick, int button, bool down);

๐Ÿฆ‹ DESCRIPTION ๐Ÿฆ‹

so like, this function lets you flip a button on a virtual joystick โ€” pressed or not pressed, your call, no cap.

but IMPORTANT, and I cannot stress this enough: the values you set here are not applied until the next call to SDL_UpdateJoysticks. not immediately. not right this second. the next one. ๐Ÿซ 

and SDL_UpdateJoysticks can be called directly, or it can sneak in indirectly through a bunch of other SDL APIs, including but not limited to:

  • SDL_PollEvent
  • SDL_PumpEvents
  • SDL_WaitEventTimeout
  • SDL_WaitEvent

so basically you set it, and then something updates it eventually, and that's when the world finds out ๐Ÿ’…


๐ŸŽ€ FUNCTION PARAMETERS ๐ŸŽ€

  • joystick โ€” the virtual joystick on which to set state. this is your joystick, the one you're setting state on, periodt.
  • button โ€” the index of the button on the virtual joystick to update. yes, an index, not a name, not a vibe, a number.
  • down โ€” true if the button is pressed, false otherwise. that's it, that's the whole boolean, she's simple and she's slaying ๐Ÿ™ˆ

โญ RETURN VALUE โญ

returns true on success or false on failure. and if it fails? call SDL_GetError() for more information, she'll tell you what went wrong ๐Ÿฅบ


๐Ÿงš THREAD SAFETY ๐Ÿงš

it is safe to call this function from any thread. any thread. all the threads. every thread. go off, multitasking queen ๐Ÿ‘‘


๐ŸŒˆ AVAILABILITY ๐ŸŒˆ

this function is available since SDL 3.2.0. so if you're on something older, sorry bestie, no button-setting for you ๐Ÿ’€
