Subworld Library

Description
An API for modders to easily add dimensions (referred to as subworlds) to their mods, making all the necessary code injections, handling Multiplayer and managing every subworld.

HOW IT WORKS
Subworld Library does a LOT of code injection, as Terraria was not made with subworlds in mind.
Subworlds are highly customisable; from how big or small they are, to what ModSystems can update inside of them and even how they are lit.
Subworld Library removes Space, both Oceans and the Underworld from subworlds, allowing them to be extremely small without issues.

LOADING
Loading a subworld is straightforward. Loading screens can be as simple as text on a plain background, or something complex, like an item selection menu.

SAVING
Subworlds save to a directory named after the main world. A subworld and/or changes to players inside it can be temporary. Deleting a world deletes all of its subworlds as well.

MULTIPLAYER
Subworld Library works in Multiplayer with little to no extra work required from modders. A "subserver" is opened for every subworld being occupied.

一个供模组开发者使用的 API，可轻松为他们的模组添加维度（称为子世界），完成所有必要的代码注入，处理多人游戏并管理每个子世界。

The backgrounds and NPC spawns are hardcoded but you can override them.

The subworlds I make still have space and the oceans. I analyzed the code of subworlds from existing mods and found no mention of them even though they're often 100% one biome. The "hideUnderworld" option is easy to find but I see nothing that removes space. What am I doing wrong? Is this a problem with the library?

Sounds like a mod conflict, send a log and I'll try to forward it to the right people!

I'm hoping to get some help as i'm unable to use the subworlds in the stars above in multiplayer. me and my buddy have about 40 mods including calamity infernum, stars above, advanced world generation (slightly larger world) BUT the subworlds work just fine in singleplayer.

the error im getting when joining or after attempting to go into a subworld is: "System.NullReferenceException: Object reference not set to an instance of an object." right before the recipes load. Meanwhile, my game is stuck on a loading screen "backing up Player File". after which ill get booted to the main world after about 2 minutes.

I can send the whole log if necessary, i'd appreciate if there's anything i can do to make this work on the server, thanks.

heads up that using the "Current" mod call doesn't just return null when in the main world but also causes an error log
