Many teleporting mods offer quick /home /back or /warp commands which make the game far far too easy. However, Vanilla Minecraft has a transportation problem where it just takes too long to get long distances. (And the Nether spacing is too unreliable)

This datapack adds the ability to construct a portal, which can be connected to another, allowing instant transportation between the two, at a small cost.

The goal was to make this "survival friendly" but avoiding making it so easy that it feels like a "dirt-to-diamonds" type mod. It's intentionally expensive to create and continue to use the portals so that it's not too easy- teleporting should not be a quick and easy task!

Constructing the portal:The base must be a redstone block, followed by 3 spaces (air/empty blocks) vertically, finally a Seastone Lantern crowns the top.

(Back wall of the portal is optional, I used colors to know which portal goes where)

Activating the portal:Connecting portals can be a bit complicated. To initialize a portal, you must throw an Eye of Ender onto the Redstone block. The portal will be initialized, but of course, there's nowhere for it to travel yet.
This portal (Portal A) will spit out a new Eye of Ender named "Port Key" which can be placed into another portal to connect, allowing teleportation from Portal B back to Portal A. A new Port Key will be generated for Portal B, which, when tossed into Portal A will give bi-directional travel.

Multiple Portals:You can throw a fresh Eye of Ender into an existing portal to create an additional Port Key pointing to that portal. Each portal can only go to 1 location, however you can have multiple portals going to the same location.
Using the portal:By default, the portals are passive- they do not teleport anything until they are primed. Priming a portal is done by throwing a Chorus Fruit into it. This will consume the Chorus Fruit, but allow you to travel through the portal. (No cooldown, and once the portal is primed it will remain primed until somebody uses the portal.)
