I can help you create a website to host Eaglercraft 1.12.2. I'll build a simple Next.js application that can serve as the hosting platform for the Eaglercraft client.

How to Complete the Setup

To fully set up your Eaglercraft website, you'll need to:

1. Get the Eaglercraft client files: You'll need to find and download the Eaglercraft 1.12.2 client files from a trusted source. These typically include JavaScript files like classes.js and other resources.
2. Add the files to your project: Place these files in the /public/eaglercraft directory of your project.
3. Update the HTML file: Modify the /public/eaglercraft/index.html file to properly load the Eaglercraft JavaScript files according to the documentation that comes with the client files.
4. Deploy your website: You can deploy this website to Vercel or any other hosting service that supports Next.js applications.

The website I've created includes:

• A homepage with information about Eaglercraft
• A dedicated play page that loads the Eaglercraft client in an iframe
• Responsive design that works on various devices
• Clear instructions in the README.md file for completing the setup

Note that hosting Eaglercraft may have legal implications, as it's a third-party implementation of Minecraft. Make sure you have the legal right to host it in your jurisdiction.
