Graphics / Re: sf::text and vectors help

Thanks for the reply, I don't think I explained my problem very well, usually I would do this if I had a set number of time to iterate:

sf::Text example[10];

for (int j = 0, j < 10, j ++)
{
example[j].setFont(font);
example[j].setPosition(sf::vector2f( j , j ));
example[j].setFillColour(sf::Colour::White);
example[j].setString(std::to_string(j));
}

However, as I do not know how many iterations I will have until later in my program I was looking for something like this:

//number from different class
int iterations;

sf::Text std::vector<?> example //I know this does not work but I am unsure how to represent what I mean

for (int j = 0, j < iterations, j ++)
{
example[j].setFont(font);
example[j].setPosition(sf::vector2f( j , j ));
example[j].setFillColour(sf::Colour::White);
example[j].setString(std::to_string(j))
}

edit: changed all the 'i' in the loops to 'j' as it was turning the text italic

Graphics / sf::text and vectors help

Hi guys, new here and to SFML as well as being a novice with c++, Im trying to make sf::Text work with a vector, usually I would use an array like so:

sf::Text example[10];

but as the size must be dynamic I cant use an array and have tried using a vector like so:

// x is a number retrieved from another class
int vector_no = x + 2;

std::vector<sf::Text> myVector( vector_no );

If you know a way to make this dynamic or get the vector or something else to work please let me know, thankyou.
