Cursor/Claude/Antigravity Setup

You can write CSL with any text editor, but using an editor with CSL tooling makes a huge difference: syntax highlighting, inline errors, autocomplete, and quick navigation.

It's also even easier than ever to get started thanks to tools that integrate AI agents which can help you learn and write CSL.

You’ll write .csl files inside your project’s scripts/ directory.

Installing Cursor (programmers)

We recommend Cursor (or VS Code) to develop All Out games. Our editor extension provides:

• Syntax highlighting support

• Inline compile error diagnostics

• Autocomplete

The extension is currently in closed beta, please reach out to an All Out team member for access. We expect to publish the extension on the marketplace soon.

1. Download and install Cursor

2. Add the All Out extension to Cursor

3. Open your game project folder in Cursor (the folder that contains scripts/ and res/)

All Out automatically adds some files to your project to help give AI context:

• AGENTS.md with basic information about All Out/CSL

• Agent skills to help it with animations, UI, etc...

• An mcp.json file to allow it to connect to the editor for compiling/fetching assets

Installing Claude Code (non-programmers)

Antigravity

Important note: we strongly recommend adding your game folder as a Windows Defender exclusion to improve performance.
