How to add a range of vertices to a sf::VertexArray?

[Rob92]

I was wondering if it is possible to add more than 1 vertex at a time to an sf::VertexArray.
At the moment I use the append function but I thought that I might be able to increase performance by adding multiple vertices at once. Is that possible without modifying the source code?

You can set the number of vertices in a vertex array during construction:

sf::VertexArray vertexArray(sf::Points, 100); // 100 vertices

and/or you can resize it later:

vertexArray.resize(200); // now 200 vertices

If you need maximum performances then you'd better use a std::vector<sf::Vertex> directly. sf::VertexArray is just a convenience wrapper, which offers a limited interface to std::vector operations.

Thanks, ill try using a vector
