Hello!
I’m developing a Sponge-based mod. Among other things, I want to implement the following:

This is the entry point world. The rectangles P1-P3 are “portals” - using them, the user can switch to other worlds, which represent places from my novel (e. g. a castle, a village, a place inside a building etc.).
The entry point world allows the user to walk around and get an overview of the world of my novel. If he or she is interested in some aspect, then the portals can be used to explore a part of the world in greater detail.
Question: How can I implement this switching to different worlds technically?
One option would be to creat a giant map, subdivide it into regions (each of which corresponds to a particular place, i. e. one for P1, one for P2 etc.) and set up portals so that if the user enters the portal, he or she is teleported to the respective part of the map.
Are there any other options?
Thanks
Dmitri Pisarenko
