TameProtection

Wild creatures and tamed creatures no longer treat each other as enemies.

AI disclosure. This mod was written with AI assistance (Claude) — the Harmony patch, configuration, build tooling and documentation. It was reviewed and tested against a live Valheim 1.0.15 dedicated server. Listed under the AI Generated category.

This restores the ProtectTamedFromEnemies behaviour from Wendigo's CreatureCarry 1.3.0, which Eradorn's CustomCreatureCarry fork deliberately left out ("There are no egg-hatching, OdinMounts, ChebsNecromancy or general tame-protection changes").

The effect is mutual: enemies will not target your tames, and your tames will not start fights with enemies. Wild-vs-wild and tame-vs-tame hostility is untouched, so normal combat and your own attacks on tames work exactly as in vanilla.

Install

Install on the server and on every client.

The patch runs client-side - BaseAI.UpdateAI is gated on IsOwner, so hostility checks happen on whichever peer owns the creature, which on a dedicated server is the nearby player's client. Every player therefore needs it; a player without it still sees their own creatures hunt tames.

The server copy makes the configuration authoritative. Without it, nothing is synced and each player silently keeps their own local settings - which matters here, because clients own different creatures, so mismatched settings protect tames or not depending on who is standing nearest.

• r2modman / Thunderstore Mod Manager: search for TameProtection by N3bby and install.
• Manual: copy plugins/TameProtection/ into BepInEx/plugins/.
• Dedicated server: copy the same folder into the server's BepInEx plugins directory.

There is no version handshake. A client without the mod simply does not get the protection; nothing breaks.

Configuration

BepInEx/config/com.n3bby.tameprotection.cfg

Synced settings are owned by the server and pushed to clients on connect. Admins can change them live from an in-game configuration manager. Clients joining a server without the mod keep their own local values.

How it works

A single Harmony postfix on BaseAI.IsEnemy(Character, Character). The instance overload compiles to return BaseAI.IsEnemy(this.m_character, other), so patching the static method covers every caller. When exactly one of the two characters is tamed, the result is forced to false.

Built against Valheim 1.0.15 / BepInExPack 5.4.2350.

Credits

The ProtectTamedFromEnemies behaviour originates in Wendigo's CreatureCarry 1.3.0. That package shipped without a license file or source-repository URL, so no upstream code was reused here: this plugin is an independent implementation written against the decompiled BaseAI.IsEnemy signature in Valheim 1.0.15. Credit for the original idea and for identifying the right hook belongs to Wendigo.

Eradorn's CustomCreatureCarry is a 1.0 fork of CreatureCarry that keeps the carrying and deliberately omits the tame-protection feature. This plugin exists to fill that gap and is meant to sit alongside it, not replace it.
