UnityExplorer for Holdfast

An unofficial Holdfast: Nations At War repackage of UnityExplorer

4.13.6, the fork maintained by yukieiji of the original by sinai-dev. It includes

UniverseLib 1.6.2. The files are the upstream BepInEx 5 Mono release,

unchanged. The package adds a small patcher that sets the hotkey and hides UnityExplorer at startup.

UnityExplorer is an in-game inspector for mod makers.

| Panel | What it does |

| --- | --- |

| Object Explorer | Lists the loaded scenes and their objects, and searches objects, types and singletons. |

| Inspector | Shows the components, fields, properties and methods of an object or class. Values can be edited. |

| C# Console | Runs C# in the game. |

| Hooks | Adds Harmony patches to game methods from the window. |

| Freecam | A free camera. |

| Log | UnityExplorer's own log and Unity's log. |

Use

Press F7 to show or hide UnityExplorer. It starts hidden.

Install

Install through r2modman or Mod Manager. It is client side. Remove any copy

of UnityExplorer you added by hand first.

Holdfast changes

The package adds a BepInEx patcher, UnityExplorer.Holdfast.dll, in BepInEx\patchers\UnityExplorer\. When

BepInEx\config\com.sinai.unityexplorer.cfg does not exist yet, the patcher writes it with these settings.

| Setting | Value | Upstream default |

| --- | --- | --- |

| UnityExplorer Toggle | F7 | F7 |

| Hide On Startup | true | false |

On the first launch BepInEx\LogOutput.log shows:

[Info:UnityExplorer.Holdfast] Wrote com.sinai.unityexplorer.cfg with the F7 hotkey, hidden at startup.

After that the patcher leaves the file alone. Change the settings in UnityExplorer's Options panel or in the cfg

file, and they stay through updates. Holdfast already uses F1, F2 and F4.

Install & use Install: follow the bundled instructions

  1. Unzip the archive from playbuff and read the bundled readme / instructions first.
  2. Most mods rely on the game's mod loader — the usual route is a community mod manager (such as r2modman): pick this game, install, and it handles the loader and dependencies.
  3. For a manual install, put the mod files into the matching Mod / plugins folder inside the game directory.
  4. Launch the game to confirm it loaded; mods with listed dependencies need those installed as well.

Install locations vary a lot between mods — the bundled readme is the most reliable guide.
