sdlGetRectIntersection function

bool sdlGetRectIntersection(Pointer<SdlRect> a, Pointer<SdlRect> b, Pointer<SdlRect> result)

Calculate the intersection of two rectangles.

If result is NULL then this function will return false.

\param A an SDL_Rect structure representing the first rectangle. \param B an SDL_Rect structure representing the second rectangle. \param result an SDL_Rect structure filled in with the intersection of rectangles A and B. \returns true if there is an intersection, false otherwise.

\since This function is available since SDL 3.1.3.
