ArrayIndexOutOfBoundsException异常而改变场景

Question

我试图从给定精灵的抽头做出另一个从一个场景变化。要做到这一点，我创建了一个场景管理器（引许多AndEngine配方）有setCurrentScene方法。我首先进入一个启动画面，而不是菜单画面，而不是第一个游戏场景。这些场景之间的转换是没有问题做出，但是从第一场比赛的场景切换到下一个问题时开始发生。我得到的休耕消息：

这是精灵的代码来改变形象：

textBox.sprite = new StockSprite(textBox.sprite.getX(), textBox.sprite.getY(), 
       sm.engine.getSurfaceWidth(), 
       textBox.sprite.getHeight(), 
       textBox.region, sm.engine.getVertexBufferObjectManager()) { 

     @Override 
     public boolean onAreaTouched(TouchEvent pSceneTouchEvent, float x, float y){ 
       if (pSceneTouchEvent.isActionDown()){ 
         if (lineCounter == 2 || !puttingText){ 
           // If the changeScene boolean is activated we should change the scene 
           if (changeScene) { 
             // We call the scene manager method to do it 
             sm.setCurrentScene(newScene); 
           } 

           // If we got to the lineCounter to the max we wait until the 
           // player touchs the screen 
           if (lineCounter >= lines.length || !puttingText){ 
             lineCounter = 0; 
             line1.setText(""); 
             line2.setText(""); 

             if (!puttingText) { 
               // We should make he disappear 
               dem.reset(); 
               sequence[k].mImage.sprite.clearEntityModifiers(); 
               sequence[k].mImage.sprite.registerEntityModifier(dem); 
             } 
           } 
         } 
       } 
       return super.onAreaTouched(pSceneTouchEvent, x, y); 
     } 
}; 

这是seCurrentScene方法

public void setCurrentScene(AllScenes currentScene){ 
       // Change the current scene 
       this.currentScene = currentScene; 
       switch(currentScene) { 
         case SPLASH: 
           break; 
         case MAINMENU: 
           // Set the scene to be the main menu 
           mmrm = new MainMenuResourceManager(this); 
           break; 
         case NEWGAME: 
           // Load the new game resource 
           hrm = new HouseResourceManager(this, true); 
           break; 
         case LOADGAME: 
           break; 
         case NEWSPAPER: 
           nprm = new NewspaperResourceManager(this); 
           break; 
         default: 
           break; 
       } 
     } 

场面到的过渡正在做这是

public class NewspaperResourceManager { 
     private SceneManager sm; 
     private Font cFont; 
     private Text line1; 
     private Scene nScene; 
     public NewspaperResourceManager(SceneManager s) { 
       sm = s; 
       loadFont(); 
       loadText(); 
       nScene = new Scene(); 
       nScene.setBackground(new Background(1,1,1)); 
       nScene.attachChild(line1); 
       sm.engine.setScene(nScene); 

     } 

     private void loadText() { 
       // TODO Auto-generated method stub 
       line1 = new Text(0.3f*sm.engine.getSurfaceWidth(), sm.engine.getSurfaceHeight()/2, 
           cFont, "Please Ivan-san make the images!", 48, sm.engine.getVertexBufferObjectManager()); 
     } 

     public void loadFont() { 
       // Set the font for the character 
       cFont = FontFactory.create(
         sm.engine.getFontManager(), 
         sm.engine.getTextureManager(), 
         256, 
         256, 
         Typeface.create(Typeface.DEFAULT, Typeface.NORMAL), 
         32f*((float)sm.engine.getSurfaceWidth()/800), 
         true); 
       cFont.prepareLetters("abcdefghijklmnopqrstuvwxyz!?-".toCharArray()); 
       cFont.load(); 
     } 
} 

Answer 1

sequence[k].mImage.sprite.clearEntityModifiers(); 
sequence[k].mImage.sprite.registerEntityModifier(dem); 

我不知道k从哪里来，但按摩称长度为2，因此索引为0和1.在您正在处理触摸输入并且K在索引2上得到3的情况下。 索引2不存在所以它会抛出一个索引超出界限。
