Hello abichuelaaa!

The “Server is not responding” error typically indicates that there is an issue with starting your local development server. Here are some troubleshooting steps you can take:

  1. Check if another application is using the same port: Ensure that no other application is running on the port that the Needle Engine server is trying to use (default is often 3000 or 8080).

  2. Verify Node.js installation: Ensure you have Node.js installed correctly. You can run npm install in your project directory to install necessary packages.

  3. Look for installation errors: Check the console in Unity for any warnings or errors regarding the installation of the Needle Engine packages or any other dependencies.

  4. Force quit any existing server processes: If a server is still running from a previous attempt, it may block a new instance. You may need to run a terminal command to kill these processes, especially ones that include npm-cli.js or vite.

  5. Restart Unity and the server: Sometimes, simply restarting Unity or reinitializing the local server process can resolve the issue.

  6. Development mode: Ensure your project is set in Development mode, which usually gives clearer error messages.

  7. Use the specific command to start the server: If you encounter issues with auto-starting, try running the server command manually from your terminal in the project directory. Use npm run dev-host or similar based on your setup.

  8. Refer to the documentation: You can check the troubleshooting section in the Needle Engine documentation which provides more insights on connection issues (see faq).

If after going through all these steps the issue persists, please provide the logs or more details regarding the exact setup (Unity version, Node.js version, etc.), and I can assist you further!

Hello marwi!

Here’s how to execute steps 1 and 2 on both Windows and macOS:

Step 1: Check if another application is using the same port

Windows

  1. Open Command Prompt (cmd) as an administrator.
  2. Type the command:
    netstat -aon | findstr :<port>
    Replace <port> with the default port number (e.g., 3000 or 8080).
  3. If you see output indicating that the port is in use, note the last column number (PID).
  4. To find which application is using that PID, type:
    tasklist | findstr <PID>
  5. If you need to close the application, use:
    taskkill /F /PID <PID>

macOS

  1. Open Terminal.
  2. Type the command:
    lsof -i :<port>
    Replace <port> with the appropriate port number (e.g., 3000 or 8080).
  3. If an application is using the port, return the PID from the output.
  4. To close the application, use:
    kill -9 <PID>

Step 2: Verify Node.js Installation

Windows

  1. Open Command Prompt (cmd).
  2. Type the following command to check if Node.js is installed:
    node -v
    This will return the version of Node.js if installed.
  3. To check for NPM (Node Package Manager), use:
    npm -v

macOS

  1. Open Terminal.
  2. Check Node.js installation with:
    node -v
  3. For NPM, type:
    npm -v

If Node.js and NPM are not installed, you can download Node.js (which includes NPM) from the official website.

If you run into any issues or need further assistance, let me know!
