Sponge's Core

The shared plumbing behind Sponge's mods.

This mod does nothing on its own. It adds no features, changes no gameplay and

patches nothing. Install it only because another mod lists it as a dependency — your

mod manager will normally do that for you.

What it does

Several mods need the same three unglamorous things, and each is easy to get subtly

wrong:

• Their own messages between players. The game sends nothing of its own design

that a mod can attach to, so a mod that needs players to agree on something has to

bring its own channel — and attach it at the right moment, on both the host and

every client, and reattach it after a reconnect.

• A small file beside your save. For anything the game's own save has no room

for. The rule that has to hold everywhere is that a mod's own bookkeeping failing

must never disturb the game's file.

• Doing something occasionally instead of every frame. For writes to disk and

periodic sweeps.

Doing each once, in one place, means a fix reaches everything at once instead of

being applied to some copies and not others.

When you want it

Only when something else asks for it.

Keys

None.

Why it is separate from the UI library

A mod that needs to send a message but draws nothing on screen should not have to

ship a canvas, and one that draws but never talks to other players should not have to

ship networking. They are split so each mod carries only what it uses.

Compatibility

It patches nothing and touches no game behaviour, so it cannot conflict with

anything.

For mod authors

Declare the dependency so you are refused a load rather than failing later with a

missing-type error:

[BepInDependency(CorePlugin.Id, CorePlugin.Version)]

The version is a contract, bumped whenever the shared surface changes in a way a

dependent could notice.
