Title: Changing Line Color?
Post by: Solluxx on February 02, 2013, 10:54:33 pm

So after some searching I found out how to draw a line...

sf::Vertex line[2] = {sf::Vector2f(x1,y1), sf::Vector2f(x2,y2)};
screen.draw(line , 2, sf::Lines);

OK easy enough, however this draws a white line. What if I want a line of a certain color or with a certain amount of transparency? I noticed RenderTexture.draw takes a another parameter, renderstate, from the documentation. Can someone explain how I might go about this. I've looked at the documentation for renderstate but still don't understand how I would go about using it in this case, if you use it at all.

Thanks for any help you can give

The above version only uses the position component of vertices. But vertices can have a color as well:

sf::Vertex line[2] =
{
    sf::Vertex(sf::Vector2f(x1, y1), color),
    sf::Vertex(sf::Vector2f(x2, y2), color)
};
screen.draw(line , 2, sf::Lines);
