IL2CPP Issues:
* Some methods may still fail with a `MissingMethodException`, please let me know if you experience this (with full debug log please).
* Reflection may fail with certain types, see [here](https://github.com/knah/IL2CPPAssemblyUnhollower#known-issues) for more details.
## Features
* Scene Explorer: Simple menu to traverse the Transform heirarchy of the scene.
* GameObject Inspector: Various helpful tools to see and manipulate the GameObject, similar to what you can do in the Editor.
* Reflection Inspector: Inspect Properties and Fields. Can also set primitive values and evaluate primitive methods.
* Search: Search for UnityEngine.Objects with various filters, or use the helpers for static Instances and Classes.
* C# Console: Interactive console for evaluating C# methods on the fly, with some basic helpers.
* Inspect-under-mouse: Hover over an object with a collider and inspect it by clicking on it.
## How to install
### BepInEx
0. Install [BepInEx](https://github.com/BepInEx/BepInEx) for your game.
1. Download the UnityExplorer release for BepInEx IL2CPP or Mono above.
2. Take the `UnityExplorer.dll` file and put it in `[GameFolder]\BepInEx\plugins\`
3. Take the `UnityExplorer\` folder (with `explorerui.bundle`) and put it in `[GameFolder]\Mods\`, so it looks like `[GameFolder]\Mods\UnityExplorer\explorerui.bundle`.
4. In IL2CPP, it is highly recommended to get the base Unity libs for the game's Unity version and put them in the `BepInEx\unhollowed\base\` folder.
### MelonLoader
0. Install [MelonLoader](https://github.com/HerpDerpinstine/MelonLoader) for your game.
1. Download the UnityExplorer release for MelonLoader IL2CPP or Mono above.
2. Take the contents of the release and put it in the `[GameFolder]\Mods\` folder. It should look like `[GameFolder]\Mods\UnityExplorer.dll` and `[GameFolder]\Mods\UnityExplorer\explorerui.bundle`.
## Mod Config
You can access the settings via the "Options" page of the main menu, or directly from the config at `Mods\UnityExplorer\config.xml` (generated after first launch).
`Main Menu Toggle` (KeyCode)
* Default: `F7`
* See [this article](https://docs.unity3d.com/ScriptReference/KeyCode.html) for a full list of all accepted KeyCodes.
`Force Unlock Mouse` (bool)
* Default: `true`
* Forces the cursor to be unlocked and visible while the UnityExplorer menu is open, and prevents anything else taking control.
`Default Page Limit` (int)
* Default: `25`
* Sets the default items per page when viewing lists or search results.
* Requires a restart to take effect, apart from Reflection Inspector tabs.
`Default Output Path` (string)
* Default: `Mods\Explorer`
* Where output is generated to, by default (for Texture PNG saving, etc).
`Log Unity Debug` (bool)
* Default: `false`
* Listens for Unity `Debug.Log` messages and prints them to UnityExplorer's log.
## Building
If you'd like to build this yourself, you will need to have installed BepInEx and/or MelonLoader for at least one Unity game. If you want to build all 4 versions, you will need at least one IL2CPP and one Mono game, with BepInEx and MelonLoader installed for both.
1. Install MelonLoader or BepInEx for your game.
2. Open the `src\Explorer.csproj` file in a text editor.
3. Set the relevant `GameFolder` values for the versions you want to build, eg. set `MLCppGameFolder` if you want to build for a MelonLoader IL2CPP game.
4. Open the `src\Explorer.sln` project.
5. Select `Solution 'UnityExplorer' (1 of 1 project)` in the Solution Explorer panel, and set the Active config property to the version you want to build, then build it.
5. The DLLs are built to the `Release\` folder in the root of the repository.
6. If ILRepack fails or is missing, use the NuGet package manager to re-install `ILRepack.Lib.MSBuild.Task`, then re-build.

Thanks to:
* [ManlyMarco](https://github.com/ManlyMarco) for their [Runtime Unity Editor](https://github.com/ManlyMarco/RuntimeUnityEditor), which I used for some aspects of the C# Console and Auto-Complete features.
* [denikson](https://github.com/denikson) (aka Horse) for [mcs-unity](https://github.com/denikson/mcs-unity). I commented out the `SkipVisibilityExt` constructor since it was causing an exception with the Hook it attempted in IL2CPP.
