It has a position and other +/// extra attributes that will be used for drawing: in SFML, +/// vertices also have a color and a pair of texture coordinates. +/// +/// The vertex is the building block of drawing. Everything which +/// is visible on screen is made of vertices. They are grouped +/// as 2D primitives (triangles, quads, ...), and these primitives +/// are grouped to create even more complex 2D entities such as +/// sprites, texts, etc. +/// +/// If you use the graphical entities of SFML (sprite, text, shape) +/// you won't have to deal with vertices directly. But if you want +/// to define your own 2D entities, such as tiled maps or particle +/// systems, using vertices will allow you to get maximum performances. +/// +/// Example: +/// \code +/// // define a 100x100 square, red, with a 10x10 texture mapped on it +/// sf::Vertex vertices[] = +/// { +/// sf::Vertex(sf::Vector2f( 0, 0), sf::Color::Red, sf::Vector2f( 0, 0)), +/// sf::Vertex(sf::Vector2f( 0, 100), sf::Color::Red, sf::Vector2f( 0, 10)), +/// sf::Vertex(sf::Vector2f(100, 100), sf::Color::Red, sf::Vector2f(10, 10)), +/// sf::Vertex(sf::Vector2f(100, 0), sf::Color::Red, sf::Vector2f(10, 0)) +/// }; +/// +/// // draw it +/// window.draw(vertices, 4, sf::Quads); +/// \endcode +/// +/// Note: although texture coordinates are supposed to be an integer +/// amount of pixels, their type is float because of some buggy graphics +/// drivers that are not able to process integer coordinates correctly. +/// +/// \see sf::VertexArray +/// +//////////////////////////////////////////////////////////// |
