To manage several worlds, I made my own unique plugin that resembles a multiverse. One issue I had to deal with was how to make a player teleport to the nether from one world rather than the level world, which appears to happen automatically. I accomplish this by using PlayerChangedWorldEvent. But that event doesn't save the player's teleportation location (i.e., the nether portal); it only saves the World from which they came. Therefore, the best I can do is teleport the player back to the original world's spawn location—not the nether portal—when they return from the nether. Does anyone know how I can find out where the player is before teleporting to a different world?
I made a plugin similar to multiverse and to accomplish this problem I used PlayerTeleportEvent and checked for TeleportCause.NETHER_PORTAL and TeleportCause.END_PORTAL, and just in case double checked with event.getFrom().getWorld() != event.getTo().getWorld() Source: https://bukkit.org/threads/getting-location-of-nether-portal.504161/
