sdlGetRectAndLineIntersectionFloat function rect

bool sdlGetRectAndLineIntersectionFloat(Pointer<SdlFRect> rect, Pointer<Float> x1, Pointer<Float> y1, Pointer<Float> x2, Pointer<Float> y2,)

Calculate the intersection of a rectangle and line segment with float precision.

This function is used to clip a line segment to a rectangle. A line segment contained entirely within the rectangle or that does not intersect will remain unchanged. A line segment that crosses the rectangle at either or both ends will be clipped to the boundary of the rectangle and the new coordinates saved in X1, Y1, X2, and/or Y2 as necessary.

\param rect an SDL_FRect structure representing the rectangle to intersect. \param X1 a pointer to the starting X-coordinate of the line. \param Y1 a pointer to the starting Y-coordinate of the line. \param X2 a pointer to the ending X-coordinate of the line. \param Y2 a pointer to the ending Y-coordinate of the line. \returns true if there is an intersection, false otherwise.

\since This function is available since SDL 3.2.0.
