please help...

how do i make a item that is a world map....
and it indicates the name of towns,continents, and my current location... thx

First of all, this topic should have been made in the RPG Maker Help section, not here.

Considering that you know at least the basics of eventing..
To make an item that shows a world map when used, make a common event that shows a world map picture when used. As simple as that.

Of course, a minimap script is also a good alternative.
