            var sceneView:SceneView = new  SceneView();
            PBE.initializeScene(sceneView);
            sceneView.width = 500 ;
            sceneView.height = 400 ;
        }
        
         private  function createHero(): void
        {
            var hero:IEntity = PBE.allocateEntity();
            hero.initialize( " Hero " );
            
            var spatial:SimpleSpatialComponent = new  SimpleSpatialComponent();
            spatial.position = new  Point( 0 , 0 );
            spatial.size = new  Point( 20 , 20 );
            hero.addComponent(spatial, " Spatial " );
            
            var render:SpriteRenderer = new  SpriteRenderer();
            render.fileName = " assets/palnt.png " ;
            render.positionProperty = new  PropertyReference( " @Spatial.position " );
            render.sizeProperty = new  PropertyReference( " @Spatial.size " );
            hero.addComponent(render, " Render " );
            
        }

}

向舞台添加一个角色，角色是由"assets/palnt.png"渲染的
