ummm, you can create a portal block and make a dummy class called teleporter<namehere> and then use that to call, but don't overwrite the dimension ids its simple to make the teleporter file
again to anyone who hasn't read the other update, I am back, sorry for being MIA for a little bit I have been swamped, and haven't been able to do much, but Im back until my school starts and then I will be MIA a little more but I will try and update frequently though and yes this tutorial is going to be updated to 1.3.1 / 1.3.2 very soon once I figure the new stuff out and have time to write it
This part is slowed right now because of all the things I have been doing, (ie learning the code again and other things of that nature)
