using UnityEngine;

using System.Collections;

public class TestSprite : MonoBehaviour {

    public Sprite spriteA;

    public Texture2D Tex;

    // Use this for initialization

    void Start () {

        Tex = Resources.Load("Enter") as Texture2D;

        //Create(源资源，对应sprite的矩形，对应sprite的中心点坐标)

        spriteA = Sprite.Create(Tex, new Rect(, , , ), new Vector2(0.5f, 0.5f));

        gameObject.GetComponent<SpriteRenderer>().sprite = spriteA;

    }

    // Update is called once per frame

    void Update () {

    }

}
