How to do so ...

As you do so, the plugin worked only at home in the world, more than any where? If that is possible please give code)
P.S Sorry for bad English, I'm just Russian.

What are you talking about?

I want to make the server mini-games, but do not know how to bind to a specific plugin world. Plugin Tntrun peace Tntrun1

Unless you write the plugin specific for that world, it works for all worlds.

Can be a small example?

No. It is hard to do that without real code.
Make your own plugins if you want that.
