What does it do?
This plugin enables you to easily create a tube transit system on your server. Players can easily create transit tubes, and no commands are required to create or utilize a tube.
To use a transit tube, simply step in, and you'll be automatically transported.

Building Tubes
Creating a transport tube is simple. To create a transport tube, you need to place multiple links, 2 blocks apart. A link is composed of 8 iron blocks + 4 redstone torches, and links should be placed 2 blocks apart.
Once multiple links have been placed, you'll be able to start using the tube. Encasing the tube in glass is recommended, but not required for usage.

Thanks for your support, and I can't wait to hear your feedback!
