27 | *NACHRICHT: |
---|
28 | * |
---|
29 | * Hier empfehle ich euch die gesamte Spielogik unter zu bringen. Viele Funktionen werden automatisch |
---|
30 | * bei gewissen Ereignissen aufgerufen bzw. lösen Ereignisse aus |
---|
31 | * |
---|
32 | *Z.B: |
---|
33 | * start() //wird aufgerufen, bevor das Spiel losgeht |
---|
34 | * end() //wenn man diese Funktion aufruft wird |
---|
35 | * pawnKilled() // wird aufgerufen, wenn ein Pawn stirbt (z.B: wenn ) |
---|
36 | * playerScored() // kann man aufrufen um dem Spieler Punkte zu vergeben. |
---|
37 | * |
---|
38 | * |
---|
39 | *TIPP: Eclipse hilft euch schnell auf bereits vorhanden Funktionen zuzugreifen: |
---|
40 | * einfach "this->" eingeben und kurz warten. Dann tauch eine Liste mit Vorschlägen auf. Wenn ihr jetzt weiter |
---|
41 | * tippt, werden die Vorschläge entsprechend gefiltert. |
---|
42 | * |
---|
43 | * |
---|
44 | *TIPP: schaut euch mal Tetris::createStone() an. Dort wird ein TetrisStone-Objekt (ControllableEntity) erzeugt, |
---|
45 | * ihm ein Template zugewiesen (welches vorher im Level definiert wurde und dem CenterPoint übergeben wurde) |
---|
46 | * Ähnlich könnt ihr vorgehen, um einen Turm zu erzeugen. (Zusätzlich braucht ein Turm noch einen Controller) |
---|
47 | * z.B: WaypointPatrolController. Wenn kein Team zugewiesen wurde bekämpft ein WaypointPatrolController alles, |
---|
48 | * was in seiner Reichweite liegt. |
---|
49 | * |
---|
50 | * |
---|
51 | *HUD: |
---|
52 | * Ein Gametype kann ein HUD (Head up Display haben.) Z.B: hat Pong eine Anzeige welcher Spieler wieviele Punkte hat. |
---|
53 | * Generell kann man a) Grafiken oder b) Zeichen in einer HUD anzeigen. |
---|
54 | * Fuer den ersten Schritt reicht reiner Text. |
---|
55 | * |
---|
56 | * a) |
---|
57 | * PongScore.cc uebernehmen und eigene Klasse draus machen. |
---|
58 | * Wenn ihr bloss anzeigen wollt wieviele Punkte der Spieler bereits erspielt hat (Punkte = Kapital fuer neue Tuerme) dann orientiert ihr euch an |
---|
59 | * TetrisScore.cc (im pCuts branch): http://www.orxonox.net/browser/code/branches/pCuts/src/modules/tetris/TetrisScore.cc |
---|
60 | * Ich habe TetrisScore lediglich dazu gebraucht, um eine Variable auf dem HUD auszugeben. Ein Objekt fuer statischen Text gibt es bereits. |
---|
61 | * |
---|
62 | * b) |
---|
63 | * Im naesten Schritt erstellt man die Vorlage fuer das HUD-Objekt: siehe /data/overlays/pongHUD |
---|
64 | * OverlayText ist eine Vorlage fuer statischen text zb: "Points Scored:". Aus mir nicht erklaerlichen Gruenden sollte man die OverlayText |
---|
65 | * Objekte immer erst nach dem PongScore anlegen. |
---|
66 | * |
---|
67 | * c) Im TowerDefense gamtype muss im Constructor noch das HUD-Template gesetzt werden. |
---|
68 | * |
---|
69 | * d) in CMakeLists.txt noch das Module includen das fuer die Overlays zustaendig ist. Siehe das gleiche File im Pong module. |
