蔔若的代碼筆記-Unity系列-第五章：讀取本地圖檔

public Sprite sp;
    IEnumerator loadSprite(string path)
    {
        string filePath = path;
        WWW www = new WWW(filePath);
        yield return www;

        Texture2D texture = www.texture;
        sp = Sprite.Create(texture, new Rect(0, 0, texture.width, texture.height), new Vector2(0.5f, 0.5f));
        

    }
}
           

這樣，我們就能将本地圖檔加載到sp裡面，通過觀察者模式，可以動态顯示圖檔。

示例程式：

// Use this for initialization
	void Start () {
        StartCoroutine(loadSprite("file://" +"C:\\Users\\HP\\Desktop\\相冊\\合照\\IMG_7438.jpg"));
	}
    public Image img;
	// Update is called once per frame
	void Update () {
		
	}
    public Sprite sp;
    IEnumerator loadSprite(string path)
    {
        string filePath = path;
        WWW www = new WWW(filePath);
        yield return www;

        Texture2D texture = www.texture;
        //因為我們定義的是Image，是以這裡需要把Texture2D轉化為Sprite
        sp = Sprite.Create(texture, new Rect(0, 0, texture.width, texture.height), new Vector2(0.5f, 0.5f));
        img.sprite = sp;

    }
           

需要注意，在pc端，需要加上

"file://"
