SLIC-Reference : : CreateCity

Arguments:

owner, nearlocation, distance[, savecity]

Type:

int

Create a city belonging to owner, at approximately distance tiles away from nearlocation

If a city variable is passed in to savecity, it will contain the newly created city after this function returns. Example:

//when the first city is created (i.e. I settle a settler)

city_t my_city;
city_t new_city;

HandleEvent(CreateCity) post
{

    if(IsHumanPlayer(player[0]))
    {
        my_city = city[0];

        //I want to create a city about 5 tiles from my first city,
        //and then save the new city in a variable
        CreateCity(player[0], my_city.location, 5, new_city);

    }

}

tested working
