AndEngine (Android) kullanarak hareketli nesne nasıl hareket ettirilir

Question

Android'de bir oyun geliştirmek için andengine kullanıyorum. Ben robot bunu yapmak nasıl J2ME sprite

bikeSprite.move(--); bu sprite kullanmak istiyorum

this.mTexture = new Texture(32, 32, TextureOptions.BILINEAR_PREMULTIPLYALPHA); 
      this.mFaceTextureRegion = TextureRegionFactory.createFromAsset(this.mTexture, this, "gfx/bike.png", 0, 0); 
---- and i place like 
Sprite bikeSprite= new Sprite(20, 50, this.mFaceTextureRegion); 

gibi sprite bir nesneyi yerleştirilir. SetPosition kullanmak istemiyorum.
