Resource Pack needed, check installation below for details.

A global portal system using books(not the ingame item or GUI, a custom in world display) allowing the dynamic creation of portals anywhere in the overworld.

All you have to do is craft a Portal Core(1 enderpearl and 1 copper ingot), place a sign on the front of a lectern with the second line being the name you want for this portal and then drop the Portal Core onto the lectern.

Features:

• Doesn't use chunk loaders
• If someone removes a portal while the book is open it waits until there is no player nearby before it updates to prevent misclicks
• Theoretically the max portal count should be around 2,000,000(due to using scoreboard to hold values)
• No commands needed by the users so it is noob friendly

How it works:

1. Craft a copper bar and an enderpearl to create a Portal Core
2. Put a sign on the front of a lectern with the second line becoming the name of the portal
3. Throw the core onto the lectern
4. Right click the book on the lectern to open the menu
5. Right click the portal name in the book to teleport

Installation:

• Download the main file "GroxicBookTP.zip" and place it into your world datapacks folder.
• Download the "Resource Pack"
• Alternatively run the command /function groxic_booktp:disable_resourcepack when ingame to disable the enable a block display instead. Although the portal core will be broken
