# CppExplorer [](https://github.com/HerpDerpinstine/MelonLoader)
An in-game explorer and a suite of debugging tools for IL2CPP Unity games, using MelonLoader.
### Known issues
* CppExplorer may experience a `MissingMethodException` when trying to use certain UnityEngine methods. If you experience this, please open an issue and I will do my best to fix it.
* Scrolling with mouse wheel in the CppExplorer menu may not work on all games at the moment.
## How to install
Requires [MelonLoader](https://github.com/HerpDerpinstine/MelonLoader) to be installed for your game.
1. Download CppExplorer.zip from [Releases](https://github.com/sinaioutlander/CppExplorer/releases).
2. Unzip the file into the `Mods` folder in your game's installation directory, created by MelonLoader.
3. Make sure it's not in a sub-folder, `CppExplorer.dll` and `mcs.dll` should be directly in the `Mods\` folder.
## How to use
* Press F7 to show or hide the menu.
* Simply browse through the scene, search for objects, etc, most of it is pretty self-explanatory.
### Features

* Scene hierarchy explorer
* Search loaded assets with filters
* Traverse and manipulate GameObjects
* Generic Reflection inspector
* C# REPL Console
* Inspect-under-mouse
### Scene Explorer
* A simple menu which allows you to traverse the Transform heirarchy of the scene.
* Click on a GameObject to set it as the current path, or Inspect it to send it to an Inspector Window.
### Inspectors
CppExplorer has two main inspector modes: GameObject Inspector, and Reflection Inspector.
Tips:
* When in Tab View, GameObjects are denoted by a [G] prefix, and Reflection objects are denoted by a [R] prefix.
* Hold Left Shift when you click the Inspect button to force Reflection mode for GameObjects and Transforms.
### GameObject Inspector
* Allows you to see the children and components on a GameObject.
* Can use some basic GameObject Controls such as translating and rotating the object, destroy it, clone it, etc.
### Reflection Inspector
* The Reflection Inspector is used for all other supported objects.
* Allows you to inspect Properties, Fields and basic Methods, as well as set primitive values and evaluate primitive methods.
* Can search and filter members for the ones you are interested in.
### Object Search
* You can search for an `UnityEngine.Object` with the Object Search feature.
* Filter by name, type, etc.
* For GameObjects and Transforms you can filter which scene they are found in too.
### C# REPL console
* A simple C# REPL console, allows you to execute a method body on the fly.
### Inspect-under-mouse
* Press Shift+RMB (Right Mouse Button) while the CppExplorer menu is open to begin Inspect-Under-Mouse.
* Hover over your desired object, if you see the name appear then you can click on it to inspect it.
* Only objects with Colliders are supported.
### Mouse Control
CppExplorer can force the mouse to be visible and unlocked when the menu is open, if you have enabled "Force Unlock Mouse" (Left-Alt toggle). However, you may also want to prevent the mouse clicking-through onto the game behind CppExplorer, this is possible but it requires specific patches for that game.
* For VRChat, use [VRCExplorerMouseControl](https://github.com/sinai-dev/VRCExplorerMouseControl)
* For Hellpoint, use [HPExplorerMouseControl](https://github.com/sinai-dev/Hellpoint-Mods/tree/master/HPExplorerMouseControl/HPExplorerMouseControl)
* You can create your own plugin using one of the two plugins above as an example. Usually only a few simple Harmony patches are needed to fix the problem.

Thanks to:
* [ManlyMarco](https://github.com/ManlyMarco) for their [Runtime Unity Editor](https://github.com/ManlyMarco/RuntimeUnityEditor), which I used for the REPL Console and the "Find instances" snippet, and the UI style.
* [denikson](https://github.com/denikson) for [mcs-unity](https://github.com/denikson/mcs-unity). I commented out the `SkipVisibilityExt` constructor in `mcs.dll` since it was causing an exception with the Hook it attempted.
