Question How to add worlds in a plugin?

Hello! Im currently getting in to bukkit and i have learned to code basic plugins. Now im looking to create a hub plugin with portals to different gamemodes. I’ve searched far and wide across the internet but i have failed to find a way to create multiple worlds in a plugin. I know plugins such as multiverse exists, but thats not what i want. I want to be able to create multiple instances/worlds to run multiple minigames at a time. Does anybody know how to code this, or a link to a guide/tutorial? Is there a world variable? Any help is greatly appreciated!

 

Doesn't multiverse do exactly that? You said you didn't want that, but multiverse creates multiple words to run multiple minigames in different worlds.

 

Ok, ill look further into that
But what i really wanted was a way to add multiple worlds in my own plugin that i wrote myself
