+
+Instead defining the whole HUD in a single script, and then linking every object of the script into a C++ file, it is now possible to directly creating the HUD in a single C++ file. In orxonox.cc, only one command is needed:
+{{{
+HUD hud = new HUD(int zoom);
+}}}
+the idea is to create a flexible HUD, which can become bigger or smaller easily. 
+
+A simple element of the HUD can be created as following:
+{{{
+Ogre:: OverlayManager& overlayManager = Ogre:: OverlayManager::getSingleton();
+Ogre:: OverlayElement* element = overlayManager.createOverlayElement("Panel",name);
+}}}
+
+In the second step, it is to create few inherited classes to Ogre:: OverlayElement, so more complicated and often used elements can be easily implemented. There is a problem about inheritance: Ogre:: OverlayElement doesnt have a constructor for itself, and Ogre:: OverlayManager::getSingleton().createOverlayElement() only creates an OverlayElement, but not its inherited classes. I could not find out how to inherit Ogre:: OverlayElement, so I wrote classes, which have an OverlayElement as public variable and several functions to change this OverlayElement. 
+
+Class Bar:
+{{{
+class _OrxonoxExport Bar
+{
+
+.....
+.....
+
+public:
+  Ogre:: OverlayElement* element;
+
+  Bar(Ogre:: Real left, Ogre:: Real top, Ogre:: Real width, Ogre:: Real height,
+      int dir, int colour, std::string name);
+  ~Bar(void);
+  void reset(int percentage);
+  void setColour(int colour);
+  void show();
+  void hide();
+};
+}}}
+
+Single elements cannot be directly put into HUD, they have to be added into a panel at first. The panel will be set into the whole overlay afterwards. 
+{{{
+Bar* energyCounter;
+Ogre::OverlayContainer* energyCounterPanel;
+
+...
+
+Ogre::Overlay* orxonoxOverlay = overlayManager.create("Orxonox/HUD"); 
+orxonoxOverlay->add2D(energyCounterPanel);
+orxonoxOverlay->show();
+}}}

 == TODO ==
 
- * To make HUD cuter, easier to use. 
+ * To find out how to write letters or numbers with C files. 
+ * To create more module classes.
  * To realize Radar System.
