I see that there have been a fair amount of views for this post but nothing that indicates any one has tried the code provided.
I went thru the process indicated in the video and set up a test to see if the lua file does what it indicates.
I can report that it does indeed allow the player to teleport to a distant location from the original location and back again.
With a few text changes you are not restricted to the images used by the author. Russian is not a language I am able to understand but the video is a good guide as to the process.
I think the script might be useful for some.
