Antigravity Editor for Unreal Engine

A lightweight Unreal Engine plugin that seamlessly integrates the Antigravity Editor (a VSCode-based custom editor) as a Source Code Editor within Unreal Engine.

This plugin leverages Unreal Engine's ISourceCodeAccessor interface to ensure that clicking on C++ classes, blueprint nodes, or compilation errors inside the Unreal Editor instantly opens the correct file and line number inside your Antigravity Editor workspace.

Features

• Instant Code Navigation: Double-click C++ classes or functions in Unreal Engine to jump directly to them in Antigravity.
• Automatic Workspace Sync: Bridges Unreal Engine's project structure with Antigravity’s layout.
• Streamlined Workflow: Tailored specifically for developers utilizing the Antigravity ecosystem instead of stock VSCode or heavy Visual Studio installations.

Installation

You can install this plugin either locally to a specific project

Project-Level Installation

1. Navigate to your Unreal Engine project's root directory (where your .uproject file is located).
2. Look for a folder named Plugins. If it does not exist, create a new folder and name it exactly Plugins.
3. Clone or extract this repository directly into that folder. Your path layout should look like this:

YourProject/
├── Config/
├── Content/
├── Source/
├── Plugins/
│   └── AntigravitySourceCodeAccess/  <-- Plugin files go here
└── YourProject.uproject

---

Configuration & Setup

Once the plugin is in the correct directory, you need to recompile your project, and then enable it inside your project settings.

1. Activating the Plugin (If it is not activated already)

1. Launch your Unreal Engine project.
2. From the top menu, go to Edit > Plugins.
3. In the search bar, type Antigravity.
4. Check the Enabled box next to the Antigravity Source Accessor plugin
5. Restart the Unreal Editor if prompted.

2. Setting Antigravity as your Default Editor

1. Go to Edit > Editor Preferences.
2. On the left sidebar, navigate to the General section and select Source Code.
3. In the Source Code Editor dropdown menu, select Antigravity.

Note: If Antigravity does not appear in the dropdown menu right away, verify that your Antigravity executable path is correctly set up in your system's Environment Variables (PATH), or specify the absolute path inside the plugin's configuration settings if prompted.

How It Works & Project File Generation

Because the Antigravity Editor is built on top of a VSCode-based core architecture, it relies on standard .code-workspace files to map out your Unreal project. If Unreal Engine falls back to generating Visual Studio (.sln) files by default, you can force it to generate a VSCode workspace using any of the three following methods:

Method 1: The Editor Toggle Trick

1. Go to Edit > Editor Preferences > Source Code and temporarily set your editor to Visual Studio Code.
2. Close the editor, right-click your .uproject file, and select Generate Project Files.
3. Once the .code-workspace file is generated in your root directory, reopen the project and switch your Source Code Editor preference back to Antigravity Editor.

Method 2: Local Project Configuration Override (Recommended)

You can force the Unreal Build Tool (UBT) to always output VSCode files for this specific project by placing a configuration file inside your project's Saved directory:

1. Navigate to your project's Saved folder.
2. Create a folder named UnrealBuildTool (if it doesn't exist).
3. Copy the file named BuildConfiguration.xml from repo inside it

Manually create BuildConfiguration.xml

You can create the file manually and paste the following configuration:

<?xml version="1.0" encoding="utf-8" ?>
<Configuration xmlns="https://www.unrealengine.com/BuildConfiguration">
  <ProjectFileGenerator>
    <Format>VisualStudioCode</Format>
  </ProjectFileGenerator>
</Configuration>

Method 3: Automated Generation via Batch File

Alternatively, you can bypass the editor completely and force-generate the files via a command-line script. Copy GenerateVSCodeProjectfiles.bat in your project's root folder and drag&drop your .uproject file on it.
