Somehow the original script is unable to get the city id (on s3), by the way, send troops is already there :P anyway I will try to use the script for other purposes (if I can make it work). Check also my Travian : Navigator.

I will intergrate this into Travian : Navigator

This script concerns game Travian found at www.travian.com

Every time a village name appears on screen, the script will add an [X] next to it. If you click on the [X] you will be taken to the attack screen and the coordinates of the village will be entered automatically.

This is very helpful as you don't have to remember every coordinate of every place you want to attack, especially if you attack many places at once in the game.
