 *NACHRICHT:
 *
 * Hier empfehle ich euch die gesamte Spielogik unter zu bringen. Viele Funktionen werden automatisch
 * bei gewissen Ereignissen aufgerufen bzw. lösen Ereignisse aus
 *
 *Z.B:
 * start() //wird aufgerufen, bevor das Spiel losgeht
 * end() //wenn man diese Funktion aufruft wird
 * pawnKilled() // wird aufgerufen, wenn ein Pawn stirbt (z.B: wenn )
 * playerScored() // kann man aufrufen um dem Spieler Punkte zu vergeben.
 *
 *
 *
 *TIPP: Eclipse hilft euch schnell auf bereits vorhanden Funktionen zuzugreifen:
 * einfach "this->" eingeben und kurz warten. Dann tauch eine Liste mit Vorschlägen auf. Wenn ihr jetzt weiter
 * tippt, werden die Vorschläge entsprechend gefiltert.
 *
 *
 *TIPP: schaut euch mal Tetris::createStone() an. Dort wird ein TetrisStone-Objekt (ControllableEntity) erzeugt,
 * ihm ein Template zugewiesen (welches vorher im Level definiert wurde und dem CenterPoint übergeben wurde)
 * Ähnlich könnt ihr vorgehen, um einen Turm zu erzeugen. (Zusätzlich braucht ein Turm noch einen Controller)
 * z.B: WaypointPatrolController. Wenn kein Team zugewiesen wurde bekämpft ein WaypointPatrolController alles,
 * was in seiner Reichweite liegt.
 *
 *
 *HUD:
 * Ein Gametype kann ein HUD (Head up Display haben.) Z.B: hat Pong eine Anzeige welcher Spieler wieviele Punkte hat.
 * Generell kann man a) Grafiken oder b) Zeichen in einer HUD anzeigen.
 * Fuer den ersten Schritt reicht reiner Text.
 *
 * a)
 * PongScore.cc uebernehmen und eigene Klasse draus machen.
 * Wenn ihr bloss anzeigen wollt wieviele Punkte der Spieler bereits erspielt hat (Punkte = Kapital fuer neue Tuerme) dann orientiert ihr euch an
 * TetrisScore.cc (im pCuts branch): http://www.orxonox.net/browser/code/branches/pCuts/src/modules/tetris/TetrisScore.cc
 * Ich habe TetrisScore lediglich dazu gebraucht, um eine Variable auf dem HUD auszugeben. Ein Objekt fuer statischen Text gibt es bereits.
 *
 * b)
 * Im naesten Schritt erstellt man die Vorlage fuer das HUD-Objekt: siehe /data/overlays/pongHUD
 * OverlayText ist eine Vorlage fuer statischen text zb: "Points Scored:". Aus mir nicht erklaerlichen Gruenden sollte man die OverlayText
 * Objekte immer erst nach dem PongScore anlegen.
 *
 * c)  Im TowerDefense gamtype muss im Constructor noch das HUD-Template gesetzt werden.
 *
 * d) in CMakeLists.txt noch das Module includen das fuer die Overlays zustaendig ist. Siehe das gleiche File im Pong module.
