This plugin can let players build custom portals in a survival game, or operate them with Multiverse-Portals!
When the player walks into the portal, the plugin will teleport the player to the specified location.
To run this plugin with Multiverse-Portals(MVP), you need to set the teleport location to the coordinates of the MVP portal(MVP portal Y axis needs to be set lower then the location).
Below is my setup. I've set up five portals to different worlds added by Multiverse-Core, and these worlds are spectator mode(world, world_nether and world_the_end are survival mode).
