sdlSetJoystickVirtualTouchpad function

bool sdlSetJoystickVirtualTouchpad(Pointer<SdlJoystick> joystick, int touchpad, int finger, bool down, double x, double y, double pressure,)

Set touchpad finger state on an opened virtual joystick.

Please note that values set here will not be applied until the next call to SDL_UpdateJoysticks, which can either be called directly, or can be called indirectly through various other SDL APIs, including, but not limited to the following: SDL_PollEvent, SDL_PumpEvents, SDL_WaitEventTimeout, SDL_WaitEvent.

\param joystick the virtual joystick on which to set state. \param touchpad the index of the touchpad on the virtual joystick to update. \param finger the index of the finger on the touchpad to set. \param down true if the finger is pressed, false if the finger is released. \param x the x coordinate of the finger on the touchpad, normalized 0 to 1, with the origin in the upper left. \param y the y coordinate of the finger on the touchpad, normalized 0 to 1, with the origin in the upper left. \param pressure the pressure of the finger. \returns true on success or false on failure; call SDL_GetError() for more information.

\since This function is available since SDL 3.1.3.
