Welcome to another one command creation! This one may sound over powered, but I've made sure it is balanced. Let's get on to it!

What is it?
This command creation adds survival friendly teleporters. They can teleport players between five hundred to two thousand blocks away from the teleporter. Each teleporter has only one use, so use it wisely. Teleporters can be crafted using:
16 Diamonds + 16 Enderpearls = 1 Teleporter Spawn Egg

How to:
Spawn a teleporter anywhere you'd like after crafting one. Then, walk into the teleporter. As you'll notice, you'll be teleported a long ways away from where you last were. Please note! The teleporters can cause some lag when entering because it is teleporting you randomly away between 500-2000 blocks. Be patient if the teleporter doesn't do anything when you enter at first. Warning! If you uninstall the machine, all teleporters in loaded chunks will be deleted.
