Open .unity3d inside .unity3d

Hi guys, i have a problem in my project, i need call a .unity3d file inside my project,
can i use WWW.LoadUnityWeb for this?

how i should use this?

this unity3d can’t stay in the same project.

You’ve read the documentation for WWW.LoadUnityWeb, right? It says you an load a new unity3d file and it’ll replace the game you’ve currently loaded. There are examples and everything.

Note that the webplayer is sandboxed, and there are restrictions on where you can load these unity3d files from.
