Unity command-line scene external tool needed.

Hello.
I need a command-line external tool to making scenes.

Example
(

1.Create a text file with this

(

Player

0

0

0

)

2.Convert using external tool text file to scene with player prefab on position x-0,y-0,z-0.

)

I don’t know about an external tool, but you can write an editor script that reads in a file and based on that file creates objects in your scene. Rather than the format you have here, I’d recommend a Comma Separated Value file if not XML for input.

In the editor, all .NET file I/O commands are available. Here is a link on creating an Editor Window:
