Detailed Description

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

cpp3ds::Drawable is a very simple base class that allows objects of derived classes to be drawn to a cpp3ds::RenderTarget.

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

Note that inheriting from cpp3ds::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.

Example:

class MyDrawable : public cpp3ds::Drawable
{
public :

   ...

private :

    virtual void draw(cpp3ds::RenderTarget& target, cpp3ds::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
        glBegin(GL_QUADS);
        ...
        glEnd();
    }

    cpp3ds::Sprite m_sprite;
    cpp3ds::Texture m_texture;
    cpp3ds::VertexArray m_vertices;
};

Member Function Documentation

virtual void cpp3ds::Drawable::draw ( RenderTarget &  target, RenderStates  states  ) const

protectedpure virtual

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.

Parameters

target	Render target to draw to
states	Current render states
