Instant executable script with Roslyn - Update 0.11.0

🛠️ Immediate C# Script Execution in Unity with Roslyn

This tool lets you dynamically compile and execute C# code inside the Unity Editor—no need to create or save script files! It’s perfect for automation, rapid prototyping, and integrating with LLMs (Large Language Models) for AI-driven workflows.

How It Works

• Entry Point:
  The Tool_Script.Execute method takes your C# code as a string, along with the class and static method name to invoke, and (optionally) serialized parameters.
• Validation:
  The tool checks that your code contains the specified class and method.
• Compilation:
  Uses Roslyn (Microsoft.CodeAnalysis.CSharp) to compile the code in-memory.
• Execution:
  Loads the compiled assembly, finds your static method, and invokes it on the Unity main thread.
• Result:
  Returns the result or any error as a string.

Example Usage

public class Script {
    public static object Main() {
        var go = new UnityEngine.GameObject("LLM_Created");
        return go.name;
    }
}

LLM sends this code to the tool, and it will create a new GameObject named "LLM_Created" in your scene—instantly!

It also has access to Unity Editor API, which opens a lot of possibilities.

Why Use This?

• No Project Pollution:
  Scripts are never saved to disk.
• LLM Integration:
  LLMs can generate and run Unity code on demand.
• Rapid Prototyping:
  Test ideas or automate tasks without leaving the Editor.

Requirements & Limitations

• Your code must define a class (default: Script) and a static method (default: Main).
• No top-level statements—all code must be inside a class.
• Only static methods are supported.
• Runs on the Unity main thread, so you can safely use Unity APIs.
