class RenderTarget

Detailed Description

Abstract base class for objects that can be drawn to a render target.

sf::Drawable is a very simple base class that allows objects of derived classes to be drawn to a sf::RenderTarget.

All you have to do in your derived class is to override the draw virtual function.

Note that inheriting from sf::Drawable is not mandatory, but it allows this nice syntax "window.draw(object)" rather than "object.draw(window)", which is more consistent with other SFML classes.


class MyDrawable : public sf::Drawable
public :
private :
virtual void draw(sf::RenderTarget& target, sf::RenderStates states) const
// You can draw other high-level objects
target.draw(m_sprite, states);
// ... or use the low-level API
states.texture = &m_texture;
target.draw(m_vertices, states);
// ... or draw with OpenGL directly
sf::Sprite m_sprite;
sf::Texture m_texture;
sf::VertexArray m_vertices;

Draw the object to a render target.

This is a pure virtual function that has to be implemented by the derived class to define how the drawable should be drawn.
