從一個場景轉移到另一個場景2D_android

我想製作一個有關關卡的遊戲。這意味着用戶必須在第一級殺死一些目標;如果他贏了，他會帶着新的目標和新的背景進入下一個等級。我使用this game tutorial。從一個場景轉移到另一個場景2D_android

我有這些類 ---->

package game.wael.ialhi; 

    import org.cocos2d.layers.CCScene; 
    import org.cocos2d.nodes.CCDirector; 
    import org.cocos2d.opengl.CCGLSurfaceView; 
    import org.cocos2d.sound.SoundEngine; 
    import android.app.Activity; 
    import android.content.Intent; 
    import android.os.Bundle; 
    import android.view.Window; 
    import android.view.WindowManager; 
    import android.widget.Toast; 


    public class SimpleGame extends Activity{ 
    protected CCGLSurfaceView _glSurfaceView; 

@Override 
public void onCreate(Bundle savedInstanceState) 
{ 
    super.onCreate(savedInstanceState); 

    requestWindowFeature(Window.FEATURE_NO_TITLE); 
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, 
      WindowManager.LayoutParams.FLAG_FULLSCREEN); 
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON, 
      WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON); 

    _glSurfaceView = new CCGLSurfaceView(this); 

    setContentView(_glSurfaceView); 
} 

@Override 
public void onStart() 
{ 
    super.onStart(); 


    CCDirector.sharedDirector().attachInView(_glSurfaceView); 

    CCDirector.sharedDirector().setDeviceOrientation(CCDirector 
      .kCCDeviceOrientationLandscapeLeft); 

    CCDirector.sharedDirector().setDisplayFPS(true); 

    CCDirector.sharedDirector().setAnimationInterval(1.0f/60.0f); 

    CCScene scene = GameLayer.scene(); 
    CCDirector.sharedDirector().runWithScene(scene); 
} 

@Override 
public void onPause() 
{ 
    super.onPause(); 

    CCDirector.sharedDirector().pause(); 
    SoundEngine.sharedEngine().stopSound(); 
} 

@Override 
public void onResume() 
{ 
    super.onResume(); 

    CCDirector.sharedDirector().resume(); 
} 

@Override 
public void onStop() 
{ 
    super.onStop(); 

    CCDirector.sharedDirector().end(); 
    SoundEngine.sharedEngine().stopSound(); 
} 
    }

我在這GameLayer類做了一些修改。在Update方法中我添加這些行，使用戶獲得時，他傳遞給下一個場景（GameLayer1） ---->

CCScene scene=GameLayer1.scene();       
    CCDirector.sharedDirector().runWithScene(scene);

和這個完整的類 ------>

    scene.addChild(layer); 

    return scene;

當用戶贏得背景更改但新的精靈從不出現。我怎樣才能讓新的精靈出現？

CCdirector.sharedDirector().runWithScene(scene);

這是否會導致語法錯誤？

你有沒有刪除當前層

removeFromParentAndCleanup(true);

或

removeSelf();

後可以更換現場

CCScene scene = GameLayer.scene(); 
    CCDirector.sharedDirector().replaceScene(scene);

你也給所有變量重置爲初始位置。

你必須使用pushScene爲下一級

CCScene scene = GameLayerSec.scene(); 
    CCDirector.sharedDirector().pushScene(scene); 

    GameLayerSec.scene() should be the next scene you designed for your next level.

CCMenuItem level1 = CCMenuItemLabel.item("Level 1", this, "level1"); 


    CCMenuItem items[] = { level1}; 
    CCMenu menu = CCMenu.menu(items); 
    menu.alignItemsVertically(50); 
    this.addChild(menu); 

public void level1(Object sender) { 
    System.out.println("!!!!!!!!!!!!!!!!!!!!!!!!!!!"); 
    CCScene scene = GameLayer.scene(); 
    CCDirector.sharedDirector().pushScene(scene); 
    System.out.println("&&&&&&&&&&&&&&&&&&&&&&&&&&&"); 
}
