+<div class="block">The class <a href="GameObject.html" title="class in gameobjects"><code>GameObject</code></a> represents a (possibly animated) object appearing in a level of the
+ game. It is therefore attached to an instance of the class <a href="../playground/Playground.html" title="class in playground"><code>Playground</code></a>. A GameObject has
+ at least the following properties:
+ <ul>
+ <li>2D screen position
+ <li>2D speed
+ <li>a name that is unique within a certain <a href="../playground/Playground.html" title="class in playground"><code>Playground</code></a><br>
+ <li>a reference to the <a href="../playground/Playground.html" title="class in playground"><code>Playground</code></a> object it belongs to<br>
+ <li>a reference to an instance of <a href="../controller/ObjectController.html" title="class in controller"><code>ObjectController</code></a> that handles the movement
+ logic of the object<br>
+ <li>a (circular) radius for simple collision checking. This may be handled differently in
+ subclasses<br>
+ </ul>
+ The main task of GameObject, or its subclasses, is to draw the object on the screen, which is
+ handles by the <a href="#draw(java.awt.Graphics2D)"><code>draw(Graphics2D)</code></a> method. It is this method that must be redefined if a
+ new appearance should be realized. For introducing new behavior, it is sufficient to supply a
+ different <a href="../controller/ObjectController.html" title="class in controller"><code>ObjectController</code></a> instance when constructing a GameObject.</div>
