Method SDL.flip()

Method flip

int flip(SDL.Surface|void screen)

Description

On hardware that supports double-buffering, this function sets up a flip and returns. The hardware will wait for vertical retrace, and then swap video buffers before the next video surface blit or lock will return. On hardware that doesn't support double-buffering, this is equivalent to calling SDL.update_rect(screen, 0, 0, 0, 0)

The SDL.DOUBLEBUF flag must have been passed to SDL.set_video_mode() when setting the video mode for this function to perform hardware flipping.

Parameter screen

The screen object to flip. If missing, the default screen is used.

Returns

This function returns 1 if successful, or 0 if there was an error.
