Syntax

typedef struct SDL_ControllerAxisEvent
{
    Uint32 type;        /**< ::SDL_CONTROLLERAXISMOTION */
    Uint32 timestamp;   /**< In milliseconds, populated using SDL_GetTicks() */
    SDL_JoystickID which; /**< The joystick instance id */
    Uint8 axis;         /**< The controller axis (SDL_GameControllerAxis) */
    Uint8 padding1;
    Uint8 padding2;
    Uint8 padding3;
    Sint16 value;       /**< The axis value (range: -32768 to 32767) */
    Uint16 padding4;
} SDL_ControllerAxisEvent;

Data Fields

Uint32	timestamp	the timestamp of the event
SDL_JoystickID	which	the joystick instance id
