+    @brief
+        The PongCenterpoint implements the playing field @ref orxonox::Pong "Pong" takes place in and allows for many parameters of the minigame to be set.
+        The playing field resides in the x,z-plane, with the x-axis being the horizontal axis and the z-axis being the vertical axis.
+        
+        Various parameters can be set:
+        - The <b>dimension</b> is a vector, that defines the width and height of the playing field. The default is <em>(200, 120)</em>.
+        - The <b>balltemplate</b> is a template that is applied to the @ref orxonox::PongBall "PongBall", it can be used to attach different things to it, e.g. its @ref orxonox::Model "Model". See below for a usage example.
+        - The <b>battemplate</b> is a template that is applied to the @ref orxonox::PongBall "PongBat", it can be used to attach different things to it, e.g. its @ref orxonox::Model "Model". See below for a usage example.
+        - The <b>ballspeed</b> is the speed with which the @ref orxonox::PongBall "PongBall" moves. The default is <em>100</em>.
+        - The <b>ballaccfactor</b> is the acceleration factor for the @ref orxonox::PongBall "PongBall". The default is <em>1.0</em>.
+        - The <b>batspeed</b> is the speed with which the @ref orxonox::PongBat "PongBats" move. The default is <em>60</em>.
+        - The <b>batlength</b> is the length of the @ref orxonox::PongBat "PongBats" as the percentage of the height of the playing field. The default is <em>0.25</em>.
+        
+        An example in XML of the PongCenterpoint would be:
+        
+        First the needed templates:
+        The template for the @ref orxonox::PongBall "PongBall".
+        @code
+        <Template name="pongball">
+          <PongBall>
+            <attached>
+              <Model mesh="sphere.mesh" scale="2" />
+              <ParticleSpawner name="hiteffect" position="0,0,0" source="Orxonox/sparks2" lifetime="0.01" autostart="0" mainstate="spawn" />
+            </attached>
+            <eventlisteners>
+              <EventTarget target="hiteffect" />
+            </eventlisteners>
+          </PongBall>
+        </Template>
+        @endcode
+        As can be seen, a sphere is attached as the @ref orxonox::Model "Model" for the @ref orxonox::PongBall "PongBall", and also an @ref orxonox::EventListener "EventListener" that triggers a @ref orxonox::ParticleSpawner "ParticleSpawner", whenever the ball hits the boundaries is attached.
+        
+        Additionally the template for the @ref orxonox::PongBat "PongBat".
+        @code
+        <Template name="pongbatcameras" defaults="0">
+          <PongBat>
+            <camerapositions>
+              <CameraPosition position="0,200,0" pitch="-90" absolute="true" />
+            </camerapositions>
+          </PongBat>
+        </Template>
+
+        <Template name="pongbat">
+          <PongBat camerapositiontemplate=pongbatcameras>
+            <attached>
+              <Model position="0,0,3" mesh="cube.mesh" scale3D="14,2,2" />
+            </attached>
+          </PongBat>
+        </Template>
+        @endcode
+        As can be seen, there are actually two templates. The first template is needed to set the camera for the @ref orxonox::PongBat "PongBat". The second template ist the actual template for the @ref orxonox::PongBat "PongBat", the template for the camera position is added and a @ref orxonox::Model "Model" for the @ref orxonox::PongBat "PongBat" is attached.
+        
+        Finally the PongCenterpoint is created.
+        @code
+        <PongCenterpoint name="pongcenter" dimension="200,120" balltemplate="pongball" battemplate="pongbat" ballspeed="200" ballaccfactor="1.0" batspeed="130" batlength="0.25">
+          <attached>
+            <Model position="0,0,60" mesh="cube.mesh" scale3D="105,1,1" />
+            <Model position="0,0,-60" mesh="cube.mesh" scale3D="105,1,1" />
+          </attached>
+        </PongCenterpoint>
+        @endcode
+        All parameters are specified. And also two @ref orxonox::Model "Models" (for the upper and lower boundary) are attached.
+        
+        For a more elaborate example, have a look at the <code>pong.oxw</code> level file.
