One-Time Teleporter

I have teleporters to transfer players from one area to another. I wanted the ability to create a teleporter that could only be used one time.

Once a player pushes the button on the teleporter, it activates a command block teleporting player to next area, simultaneously, it activates a block of tnt, destroying a few blocks and a few redstone dusts. This breaks the redstone path to the command blocks and opens up a beam block to open sky indicating a player has already used teleporter..

To fix/reset teleporter, just replace tnt block, block above beam block and redstone dust. Bedrock protects exterior design from any damage of blast.

Included in download is a working teleporter that is sliced to show you how mechanism works, instructions on how to reset and 5 sample teleporters for you to use in your world.

Suggestions are welcome in other ways of doing this. My redstone skills are limited.

USAGE: Feel free to use or modify any of these schematics in your worlds. Credit is appreciated.
