I noticed that the Unity WordPress Plugin is ridiculously out of date and only supports up to Unity 2 if you want to show your projects using the Web Player.
So I started modifying the original plugin made by Tom Higgins and have Unity 3 projects working via the same syntax. It’s definitely a hacked together job, but it totally works for whatever I threw at it.
You can download it here: Download
Just unzip the file into your plugins directory in wp-content. You can use the exact same syntax as the original when writing posts. Just write something like this:
[WP_UnityObject src=”http://www.yourdomain.com/yourfile.unity3d” width=”640″ height=”480″/]
Let me know if you find any bugs or want any features and I’ll try my best to update the plugin.
