像马里奥的Andengine 2d侧卷轴

我在那里有个问题。我如何让人物具有重力并可以正确行走，即我需要使用哪些功能以及如何定义灯具？我需要box2d物理世界（我使用平铺地图）？所以，如果可以的话，请告诉我如何使用andengine做像马里奥一样的2D滚动平台游戏。像马里奥的Andengine 2d侧卷轴

我的代码我想要做的事：

// Character: 
    charactersprite = new Sprite(40, 0, this.character); 
    charactersprite.setScaleX(0.65f); 

    this.mScene.setOnSceneTouchListener(this); 

    // PHYSICS 
    final FixtureDef characterfictur = PhysicsFactory.createFixtureDef(0, 0f,0.5f); 


    this.mScene.registerUpdateHandler(this.mPhysicsWorld); 

    final Body body = PhysicsFactory.createBoxBody(this.mPhysicsWorld, charactersprite, BodyType.DynamicBody, characterfictur); 

    this.mPhysicsWorld.registerPhysicsConnector(new PhysicsConnector(charactersprite, body, true, false)); 
    mScene.attachChild(charactersprite); 

    createUnwalkableObjects(mTMXTiledMap); 
    final PhysicsHandler physicsHandler = new PhysicsHandler(charactersprite); 
    charactersprite.registerUpdateHandler(physicsHandler); 


    // HUD 
    HUD my = new HUD(); 
    Sprite forward = new Sprite(50, CAMERA_HEIGHT - 170, forwardr){ 
     @Override 
     public boolean onAreaTouched(TouchEvent pEvent, float pX, float pY){ 
      if(!pEvent.isActionUp()){ 
       charactersprite.getTextureRegion().setFlippedHorizontal(false); 

      body.setLinearVelocity(new Vector2(CHAR_MOVING_SPEED,body.getLinearVelocity().y)); // Don't look at there 
      //body.applyLinearImpulse(new Vector2(2,0), body.getPosition()); 

      }else{ 
       //body.applyLinearImpulse(new Vector2(0,0), body.getPosition()); 
       physicsHandler.setVelocity(0, 0); 
       body.setLinearVelocity(new Vector2(0,body.getLinearVelocity().y)); // Don't look at there 
      } 
      return false; 

         } 
    };

和小前锋：

private void createUnwalkableObjects(TMXTiledMap map){ 
    // Loop through the object groups 

    for(final TMXObjectGroup group: map.getTMXObjectGroups()) { 

      //if(group.getTMXObjectGroupProperties().containsTMXProperty("Zeme", "true")){ 
        // This is our "wall" layer. Create the boxes from it 

        for(final TMXObject object : group.getTMXObjects()) { 

          final Rectangle rect = new Rectangle(object.getX(), object.getY(),object.getWidth(), object.getHeight()); 
          final FixtureDef boxFixtureDef = PhysicsFactory.createFixtureDef(0, 0,1f); 
          PhysicsFactory.createBoxBody(this.mPhysicsWorld, rect, BodyType.StaticBody, boxFixtureDef); 
          rect.setVisible(false); 
          mScene.attachChild(rect); 
        } 
      //} 
    }

}

因此，它没有正常工作。所以我做错了什么？请帮帮我。非常感谢！
