调试背景

2D游戏的制作最重要的是层的设置

先设置两个层①Layers②Edit Layers③Sorting Layers添加两个层BackGround和Front

调试大雁

创建2D object改名BackGround设置背景图片修改为BackGround 0层

创建2D object添加大雁图片Ctrl+6，保存，把大雁动态模型全选，插入。调整时间可以看起来舒服，调整所在层为BackGround 1层

添加脚本使大雁从屏幕右边开始飞入左边飞出

publicclassSwanFly : MonoBehaviour {

    //天鹅起飞的位置

    privateVector3 startPosition;

    publicfloat speed;

         // Use this for initialization

         void Start () {

        Debug.Log("屏幕的宽度" + Screen.width);

        Debug.Log("屏幕的高度" + Screen.height);

        Vector3 screenSize = Camera.main.ScreenToWorldPoint(newVector3(Screen.width, Screen.height, 0));

        float swanExtentsX = transform.GetComponent<Renderer>().bounds.extents.x;

        startPosition = newVector3(screenSize.x + transform.position.y, transform.position.z);
