sdlRenderDrawLine function

int sdlRenderDrawLine(
  1. Pointer<SdlRenderer> renderer,
  2. int x1,
  3. int y1,
  4. int x2,
  5. int y2,
)

Draw a line on the current rendering target.

SDL_RenderDrawLine() draws the line to include both end points. If you want to draw multiple, connecting lines use SDL_RenderDrawLines() instead.

\param renderer the rendering context \param x1 the x coordinate of the start point \param y1 the y coordinate of the start point \param x2 the x coordinate of the end point \param y2 the y coordinate of the end point \returns 0 on success or a negative error code on failure; call SDL_GetError() for more information.

\since This function is available since SDL 2.0.0.
