Valheim Prefab Parser

⚠️ This is a developer / modder tool — it adds nothing to gameplay.
If you are a regular player looking for new content, this mod is not for you.

A lightweight BepInEx plugin that scans all of Valheim's loaded prefabs at runtime, categorizes them, and writes a structured report to a text file next to the plugin .dll. Intended for mod authors and QA testers who need a quick reference of every prefab name available in the current game version — including those added by other mods.

What it does

On every game load the mod waits for both ObjectDB and ZNetScene to finish initializing, then collects all prefabs from three sources:

• ObjectDB.m_items and m_recipes — all items and crafting recipes
• ZNetScene.m_prefabs — every networked object registered in the scene
• Resources.FindObjectsOfTypeAll — remaining Unity assets not in either registry

The result is a single .txt file with a summary table and a full list sorted into 32 categories (weapons, armor, creatures, buildings, VFX, etc.).

Typical output: 6000+ prefabs across 32 categories.

Who needs this

Installation

1. Install BepInExPack for Valheim if you haven't already.
2. Drop ValheimPrefabParser.dll into BepInEx/plugins/ValheimPrefabParser/.
3. Launch the game and load any world.
4. The output file appears at BepInEx/plugins/ValheimPrefabParser/valheim_prefabs.txt.

Configuration

Config file is generated at BepInEx/config/com.yourname.valheimprefabparser.cfg on first run.

Compatibility

• No gameplay changes, no ZDO writes, no RPC calls.
• Read-only — safe to add or remove mid-modpack without side effects.
• Works alongside any other mod; does not patch any method that other mods commonly touch.
• Tested on Valheim 0.220.x.

[2.0.0] - 2026-02-22

Fixed

• ObjectDB was empty on parse — the mod used to start parsing immediately after ZNetScene.Awake, before ObjectDB had time to populate. Now a coroutine waits until ObjectDB.instance.m_items.Count > 0 before starting. Singleplayer and multiplayer (via CopyOtherDB fallback patch) both handled correctly.
• ~2400 prefabs were missing — the Resources.FindObjectsOfTypeAll filter parent == null was discarding child objects inside prefabs (meshes, colliders, LOD levels). Filter removed; total count is now back to ~6000+.
• Reflection used for m_boss — replaced GetField("m_boss") with direct access to the public field character.m_boss. Faster and more robust.
• O(n²) duplicate check — List.Contains inside the collection loop replaced with HashSet<int> keyed on GetInstanceID(). O(1) per lookup.
• Code duplication — ParseSync and ParseCoroutine previously both contained a full copy of the formatting logic. Extracted into a shared BuildContent() method.
• Output path — file is now written next to the plugin .dll instead of the root plugins/ folder.
• Unused Jotunn dependency — removed from .csproj; the mod has no runtime dependency on Jotunn.

Added

• IncludeComponentList config option — when enabled, prints every component on each prefab. Useful for deep inspection. Disabled by default (keeps file small).
• Summary table at the top of the output file showing prefab count per category.
• 30-second timeout in WaitForObjectDBAndParse — if ObjectDB never becomes ready, parsing proceeds with whatever data is available and logs a warning.
• Categories 22_Minerals now also catches MineRock5, 32_SFX added for audio-only prefabs without a ZNetView.

Changed

• VFX detection now checks for a ParticleSystem component first; name-based fallback (vfx_, sfx_, fx_) is secondary.
• Output format improved: added Unicode box-drawing borders, summary section, and timestamp in yyyy-MM-dd HH:mm:ss format.
• Version bumped to 2.0.0.

[1.0.2] - initial release

• Initial public release.
• Categorized prefab dump from ObjectDB, ZNetScene, and Resources.
• Coroutine mode to reduce frame hitches.
