Nearest Wayshrine to Player

[CleetusTheDiabeetus]

Hello All,

I was looking for some guidance on where to start for creating an AddOn with a UI that displays the closest Wayshrine to a player's position.

I need to:

Determine Player PosX, PosY

Find All Wayshrine Locations

Calculate the closest wayshine from the players location

Output that information to a UI

Where can I pull player position?
Where can I get a list of wayshrines and their locations?

P.S:
I tried looking at the "FasterTravel" AddOn which determines the closest wayshrine to your quest but it was too advanced for me to figure out exactly what the functions they created were doing.

Thank you.
