sdlIntersectFRect function

bool sdlIntersectFRect(
  1. Pointer<SdlFRect> a,
  2. Pointer<SdlFRect> b,
  3. Pointer<SdlFRect> result
)

Calculate the intersection of two rectangles with float precision.

If result is NULL then this function will return SDL_FALSE.

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

\since This function is available since SDL 2.0.22.
