Changing the Level of the Multi-Play Dedicated Server Player

I’m going to use the dedicated server on azure mv, ubuntu.

If there are players 1,2,3 and levels 1 and 2, I want to allow players to move freely between these levels.

In mmorpg, players 1, 2 are in the square and 3 are in the store so that you can meet player 3 when the player goes into the store.

I look into educational channels like forums and YouTube, and it’s mostly multi-play at one level.

I’ve been searching for educational materials, and someone said
You have to create a server at each level.
A server can only create one level. So to make a game with two levels, you have to make two servers

Is this true? No suitable educational materials were found to implement this.

You might not understand it because it’s a question that I worked on with a translator. Thank you.

Yes, that statement is true. If you want to host 3 different levels at the same time you need 3 different servers. However, since it seems that you don’t want to do so, you can simply have one level, let’s call it level 4.

In level 4 you can import level 1, 2, 3; but keep them away from each other.

That means level 4 - level 1, level 4 - level 2
Does this mean that you can host 4 levels with one server?
Is there a technical name for this?
I want to see the educational materials about this.

There will be an error if you move the level instead of using the ip method in multi-play.

There is no educational material as far as I know, it’s basically how the engine is built.

One dedicated server can host one level. You will need three dedicated servers to host three different levels.

If you only want one dedicated server but three different levels, you will need to make one level that has all of the other three levels within it.

Okay. Thanks.
