ItemSpawnerPremium

A standalone item spawner for PEAK. Press F5 to open the browser and spawn any item in hand. Only BepInEx is required — no other mods.

Multiplayer note: items are network-instantiated by the room host, so anything you spawn is visible to everyone in the room. Use it in your own lobby, or check with your teammates first.

A continuation of the original quackandcheese-ItemSpawner, rebuilt as a single-DLL standalone mod.

The current release was developed and tested against PEAK 2.3.a (Steam build 24961053, 2026-08-28). Later game updates may add or rename items.

Features

• Localized item names — the UI is translated into all 15 game languages. Item names come from the game's own localization table; if that table has no column for your language the English name is shown, if it has no entry for the item at all the internal item name (or the prefab name) is shown, and a small number of items that the game never localized use a name bundled with this mod.
• Smart search + Pinyin (full spelling and initials, e.g. regouchang / rgc finds 热狗肠). Pinyin matching is enabled when the game language is Simplified or Traditional Chinese.
• Multi-tag categories: All / Tools / Food / Mystical / Equipment / Consumables / Misc.
• Favorites: right-click to toggle, heart marker, config persistence, favorites filter.
• Hide-unused toggle (default on): hides chess pieces, torn guidebook pages, _Prop/_TEMP/_UNUSED/_Hidden prefabs, and a short list of template/placeholder prefabs. Favorites are preserved when toggling.
• Two UI styles: HandDrawn (warm kraft paper, default) / Transparent.
• Single DLL: TinyPinyin and all 15 localization JSONs are bundled; only BepInEx is required.

Installation

1. Install BepInExPack_PEAK.
2. Put plugins/ItemSpawnerPremium.dll into BepInEx/plugins/.
3. Launch the game and press F5.

Configuration

BepInEx/config/com.itemspawnerpremium.ItemSpawnerPremium.cfg:

Section	Key	Default	Description
General	ToggleKey	F5	Key to open/close the spawn menu (UnityEngine.KeyCode).
General	Style	HandDrawn	UI style: HandDrawn / Transparent.
General	HideUnused	true	Hide decorative/unused items; set false to show everything.
Favorites	ItemNames	[]	Favorite prefab names (JSON array).

Building

Prerequisites: .NET SDK (targets net472), and a PEAK install.

1. Point GameDir at your PEAK root (the folder containing BepInEx and PEAK_Data) — either pass -p:GameDir="X:\path\to\PEAK", set a GameDir environment variable, or edit the default in Directory.Build.props. The build fails fast with a clear message if the path is wrong.
2. Run dotnet build ItemSpawnerEnhancement.csproj -c Release.
3. Output: bin/Release/ItemSpawnerPremium.dll (Debug goes to bin/Debug/, so the two never overwrite each other).

Releasing

pack.ps1 assembles dist/ItemSpawnerPremium/ from a clean Release build. It refuses to run unless the git working tree is clean and all four version strings agree (csproj, Plugin.cs, package/manifest.json, CHANGELOG.md), it runs the unit tests, and it verifies the ItemCatalog.cs invariants via verify_catalog.py. Zipping is opt-in (-Pack). See the comment header in pack.ps1 for the full release order.

Tests

tests/ItemSpawnerPremium.Tests is a net8.0 NUnit project with no Unity or BepInEx dependency: it source-links only the pure-logic files (SearchText.cs, SearchRanking.cs, ItemCatalog*.cs, FavoriteCodec.cs, Localization/Loc.cs, Localization/LocalizationCatalog.cs, TinyPinyin/*) and embeds the 15 language JSONs under the same resource names the shipped DLL uses, so the real marker parsing and English fallback chain are exercised. Localization/GameLanguage.cs is deliberately not linked — it references the game's LocalizedText type.

dotnet test tests/ItemSpawnerPremium.Tests/ItemSpawnerPremium.Tests.csproj

Covered: search normalisation and pinyin conversion (including a sweep of the whole BMP Han range asserting no character throws during decode), ranking tiers and culture-independence, the catalog sort's total-order properties, hidden rule vs. category table complementarity, favorite JSON round-trips and corrupt-input recovery, and localization key completeness across all 15 languages.

Project structure

• Plugin.cs — BepInEx entry point, config, F5 polling, GUIManager patch.
• ItemSpawnerPremiumWindow.cs — the MenuWindow subclass (pure-code UI).
• ItemListView.cs — list view, object pool, favorites, Unity lifecycle.
• SearchText.cs / SearchRanking.cs — pure-logic search normalisation, ranking and catalog ordering.
• UiEnhancer.cs — UI builder (two styles, SDF-baked sprites).
• ItemCatalog.cs / ItemCatalogMethods.cs — item catalog data + category logic.
• FavoriteStore.cs / FavoriteCodec.cs — favorites persistence and its pure-logic codec.
• Warmup.cs — panel warmup + render priming.
• TinyPinyin/ — bundled pinyin library (MIT, locally modified).
• Localization/ — 15 embedded language JSONs.
• package/ — canonical manifest.json and icon.png used to build the release folder.
• tests/ — unit tests (excluded from the mod DLL via Compile Remove).
• pack.ps1 / verify_catalog.py — release assembly and catalog invariant checks.
