Cocos2d_android Developing Simple Games

1) game layer design:

public class Wellcomelayer extends Cclayer {public wellcomelayer () {this.setistouchenabled (true); Ccsprite background1 = Ccsprite.sprite ("background.jpg"); Ccsprite Background2 = Ccsprite.sprite ("background.jpg"); Background1.setanchorpoint (0, 0); Background1.setposition ( 0, 0); This.addchild (BACKGROUND1); background2.setanchorpoint (0, 0); Background2.setposition (0, Background1.getcontentsize (). height); this.addchild (BACKGROUND2); Ccsprite logo = Ccsprite.sprite ("logo.png"); Logo.setanchorpoint (0, 0); Logo.setposition ((Ccdirector.shareddirector ( ). Winsize (). Width-logo.getcontentsize (). width)/2, Ccdirector.shareddirector (). Winsize (). HEIGHT/2); this.addchild (logo);} Game Interface layer public class Gameoverlayer extends Cclayer {public gameoverlayer (int score) {... ｝｝

2) scrolling background design

At the same time, put three pictures in the layer, vertical arrangement, and 2 pixels per frame to move downward, when the second picture to the origin, repeated loop

Background1 = Ccsprite.sprite ("background.jpg"); Background2 = Ccsprite.sprite ("background.jpg"); Background3 =　　Ccsprite.sprite ("background.jpg"); Background3.setanchorpoint (0, 0); Background2.setanchorpoint (0, 0); Background1.setanchorpoint (0, 0); This.addChild (　　BACKGROUND1); This.addchild (Background2); This.addchild (BACKGROUND3);　　　　Initialize three background Graph//Use cocos2d timing scheduling This.schedule ("Backgroundmove", 0.01f); /** * Background Move * @param dalat */public void Backgroundmove (float Dalat) {background1.setposition (0, BACKGROUND1.GETP　　Osition (). y-2);　　Background2.setposition (0, Background1.getposition (). Y +   background1.getcontentsize (). height);　　Background3.setposition (0, Background2.getposition (). Y + background2.getcontentsize (). height);　　if (Background2.getposition (). y = = 0) {background1.setposition (0, 0); }　　}

2) Background music:

context = Ccdirector.shareddirector (). getactivity ();　　Soundengine.sharedengine (). Preloadeffect (context, r.raw.game_music); Soundengine.sharedengine (). PlaySound (Context, r.raw.game_music, true);

4) Wizard design and Generation:

/** * Fired bullets * @param dalat */public void shoot (float dalat) {Ccsprite bullet = Ccsprite.sprite ("Bullet1.png");　　Bullet.setposition (Player.getposition (). x, Player.getposition (). Y + player.getcontentsize (). height);　　AddChild (bullet);　　Ccmoveby move = ccmoveby.action (5, CGPOINT.CCP (0, Winsize.getheight () + 10));　　Bullet.runaction (move);　　This.bulletList.add (bullet); 　　/** * Randomly generated enemy aircraft @param Dalat */public void Addenemy (float Dalat) {ccsprite enemy = Ccsprite.sprite ("Enemy1.png");　　Enemy.setposition (Random.nextint ((int) winsize.getwidth ()), Winsize.getheight ());　　Cgpoint p = CGPOINT.CCP (0, 0-winsize.getheight ()-20);　　AddChild (enemy);　　Ccmoveby move = Ccmoveby.action (p);　　Enemy.runaction (move);　　This.enemyList.add (enemy); }

5) Collision Detection

/** * Infer If the host is colliding with enemy aircraft * @param Dalat * @return * */public void Boom (float Dalat) {for (int i = 0; i < enemylist . Size ();　　i++) {Ccsprite enemy = Enemylist.get (i);　　if (Cgrect.intersects (Player.getboundingbox (), Enemy.getboundingbox ())) {  Ccblink blink = ccblink.action (1, 3);　　Cchide hide = Cchide.action ();　　This.enemyList.remove (i);　　Ccsequence seq = ccsequence.actions (blink, hide);　　Enemy.runaction (ENEMYDOWNSEQ);　　Player.runaction (seq);　　New Thread () {public void run () {try {thread.sleep (1000);　　} catch (Interruptedexception e) {//TODO auto-generated catch block E.printstacktrace ();　　} exitgame ();　　}}.start ();　　} if (Enemy.getposition (). Y < 0) {this.enemyList.remove (i);　　This.removechild (enemy, true); }　　}　　}
