Element2D

An abstract SuperClass, that knows how to be drawn onto a 2-dimensional screen.

• definition:

  ...
  #include "element_2d.h"
  ...
  //! A class that enables the
  class Crosshair : public PNode, public Element2D, public EventListener {
  ...
  }
  

• usage:

      void setPosition2D(int xCoord, int yCoord);
      void setAlignment(E2D_ALIGNMENT alignment) { this->alignment = alignment; };
      void setLayer(E2D_LAYER layer);
      void setVisibility(bool visible) { this->visible = visible; };
      void setBindNode(const PNode* bindNode) { this->bindNode = bindNode; };
  

  These functions are quite selfexplanatory. Important are two things:
  1. you set only a relative-position with setPosition2D
  2. when you set a bindNode, the 2D-element will follow the BindNode's Position, trying to approximate it.
