我想制作一个有关卡的游戏。这意味着在第一关中用户必须杀死一些目标，如果他赢了，他会通过新目标和新背景进入下一个关卡。我用这个游戏教程！
我有这些课程---->
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.content.Intent;

import android.view.Window;

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();
}
}
我在这个 GameLayer 类中进行了一些修改。在更新方法中，我添加了这些 ligne，以便当用户获胜时，他传递到下一个场景（GameLayer1）---->
CCScene scene=GameLayer1.scene();
CCDirector.sharedDirector().runWithScene(scene);

但是当用户只赢得背景变化时，新的精灵永远不会出现..请帮助
