(This is the documentation for SDL3, which is the current stable version. SDL2 was the previous version!)

SDL_Finger

Data about a single finger in a multitouch event.

Header File

Syntax

typedef struct SDL_Finger
{
    SDL_FingerID id;  /**< the finger ID */
    float x;  /**< the x-axis location of the touch event, normalized (0...1) */
    float y;  /**< the y-axis location of the touch event, normalized (0...1) */
    float pressure; /**< the quantity of pressure applied, normalized (0...1) */
} SDL_Finger;

Remarks

Each touch event is a collection of fingers that are simultaneously in contact with the touch device (so a "touch" can be a "multitouch," in reality), and this struct reports details of the specific fingers.

Version

This struct is available since SDL 3.1.3.
