Star Battle Playground

This repository contains a web application for playing and creating Star Battle puzzles, built entirely with client-side technologies (HTML, CSS, and JavaScript). The application logic, including puzzle generation and solving, runs in your browser, making it fast and responsive.

Smart Assists: Enable settings like automatic error highlighting and "Auto-X" to fill in logical deductions for you.

Running Locally

While the application logic is fully client-side, modern web browsers have security policies (CORS) that restrict loading resources from the local file system. Therefore, to run the app locally, you must serve the files from the project's Main directory using a simple local web server.

Clone the repository to your local machine.
Navigate into the Main directory in your terminal. For example:
```
cd path/to/StarbattlesTools/Main
```
Start a local server using one of the options below.

Option A: Using Node.js (Recommended)

If you have Node.js and npm installed, you can use npx to run a temporary server without installing any packages globally. This is a quick and modern approach.

npx serve

Option B: Using Python

If you have Python installed, you can use its simple built-in web server.

For Python 3:
```
python3 -m http.server
```
If you have an older system with Python 2:
```
python -m SimpleHTTPServer
```

Open the application in your browser. After running the server command, your terminal will display a local URL. Open that URL (typically http://localhost:3000 for npx serve or http://localhost:8000 for Python) in your browser to run the app.

Miscellaneous Tools

This repository also includes a MiscTools/ folder. This directory contains a collection of various scripts and utilities that are not part of the core puzzle application but may be useful for advanced users or for performing other interesting tasks. Feel free to explore them if you're curious.
