Core Protection Rework

A BepInEx mod for Mycopunk that reduces how hard piercing and explosive damage can skip enemy shell armor and dump damage straight into cores.

Features

• Structural armor checks — uses the live enemy component tree (EnemyShell under a core), not fragile GameObject name matching.
• Piercing falloff — IgnoreImmunity can still hit cores, but damage scales down for each living shell still attached.
• Explosive falloff — explosive, AOE, and mega-explosive core hits are scaled while shells remain.
• Vanilla bonus replacement — the free full-armor explosive core poke and the vanilla x2 explosive core bonus are replaced with configurable values (defaults: heavily reduced / no bonus).
• Config file — tune penalties, floors, and bonuses without rebuilding. Edits to the cfg on disk hot-reload in-game (debounced).

What this does not do

• It does not re-implement outer→inner shell gating (vanilla EnemyShell already blocks hits on shells that still have shell children).
• It does not force-kill cores when shells die (vanilla already handles core death when children are gone).

Getting Started

Dependencies

• Mycopunk
• BepInEx 5.4.2403+ (Mycopunk pack)
• HarmonyLib (via BepInEx)

Building

dotnet build --configuration Release

Output DLL: bin/Release/netstandard2.1/CoreProtection.dll

Installing

Thunderstore / r2modman: install the package normally.

Manual: copy CoreProtection.dll to <Mycopunk>/BepInEx/plugins/.

Configuration

After the first launch, edit:

BepInEx/config/sparroh.coreprotection.cfg

Falloff formula:

multiplier = max(MinMultiplier, 1 / (1 + ShellPenalty * aliveShells))

Multiplayer

This mod changes combat math and is marked as sandbox content that all players should run at the same version. The host’s damage path is what matters for application; keep the mod matched across the lobby.

Added

• BepInEx config for pierce/explosive toggles, shell penalties, multiplier floors, and core bonuses

Removed
