How to deploy OpenClaw on Hostinger Managed WordPress with custom plugins?

Deploying OpenClaw (a claw machine game built with Unity WebGL) on Hostinger Managed WordPress with custom plugins involves several technical steps, as Hostinger’s Managed WordPress hosting is optimized for WordPress and may not natively support Unity WebGL or custom server-side configurations. Below is a step-by-step guide:

Step 1: Prepare OpenClaw (Unity WebGL Build)

Build OpenClaw for WebGL
- Open your Unity project (OpenClaw) and switch the Platform to WebGL (File > Build Settings > WebGL).
- Adjust Player Settings:
  - Resolution & Presentation: Set Default Canvas Width/Height (e.g., 960x600).
  - Publishing Settings: Enable Compression Format (Brotli or Gzip).
- Build the project (output will be a Build folder with index.html, .js, and .data files).
Optimize for Web
- Reduce file size (Hostinger has limited storage on shared plans).
- Test the build locally (use a local server like python -m http.server or WebServer for Chrome).

Step 2: Upload OpenClaw to Hostinger

Since Hostinger Managed WordPress does not allow direct FTP access to root files (for security), use one of these methods:

Option 1: Use WordPress Media Library (Limited)

Compress the WebGL build (Build folder) into a .zip file.
Upload it via WordPress Media Library (Media > Add New).
Extract it (if possible) or manually upload files via File Manager (cPanel).

Option 2: Use Hostinger File Manager (cPanel)

Log in to Hostinger Control Panel → File Manager.
Navigate to public_html (or a subdirectory, e.g., /games/).
Upload the Unity WebGL Build folder (drag & drop).

Ensure files are accessible via:

https://yourdomain.com/games/OpenClaw/index.html

Option 3: Use Custom Plugin (Advanced)

If you want to embed OpenClaw directly in WordPress, create a custom plugin:

Go to WordPress Admin > Plugins > Add New > Upload Plugin.

Create a plugin file (openclaw-plugin.php) with:

<?php
/*
Plugin Name: OpenClaw WebGL Embed
Description: Embeds OpenClaw Unity WebGL Game.
Version: 1.0
*/
function openclaw_embed() {
    echo '<div style="width: 100%; max-width: 960px; margin: 0 auto;">';
    echo '<iframe src="/games/OpenClaw/index.html" width="100%" height="600px" frameborder="0"></iframe>';
    echo '</div>';
}
add_shortcode('openclaw', 'openclaw_embed');
?>

Activate the plugin, then use the shortcode [openclaw] in Pages/Posts.

Step 3: Handle Custom Plugins (If Needed)

If OpenClaw requires custom backend logic (e.g., scores, user auth), Hostinger Managed WordPress does not support Node.js/PHP server-side Unity integration.
Workaround: Use WordPress REST API + JavaScript (store scores in WordPress posts/comments or use a custom table).

Example (JavaScript fetch to WordPress):

fetch('/wp-json/wp/v2/posts', {
    method: 'POST',
    headers: { 'Content-Type': 'application/json' },
    body: JSON.stringify({ title: 'New High Score', content: '1000 points' })
});

Step 4: Test & Troubleshooting

Check Console Errors (Chrome DevTools → F12 → Console).
Ensure MIME Types (Hostinger must serve .data files correctly; contact support if blocked).
Alternative Hosting: If performance is poor, consider Hostinger VPS or external CDN for WebGL files.
