javascript - 在 Unity 3D 上使用 Google map API v3

Question

我需要在 Unity 3D 应用程序上插入 Google map 中的 map 。

我认为可以使用 JavaScript API v3，但我不知道如何开始。

谢谢你

您必须使用google static unity3d 中的图像 api，您还需要在 google 上注册才能获取api key。或者您可以使用this免费资源商店包，但您还必须购买uniWeb。我使用这个简单的代码片段来获取下面游戏对象上的谷歌图像:

       string url = "";
        /// <summary>
        /// Langitude/latitude of area. default Karachi is set
        /// </summary>
        public float lat =  24.917828f;

        public float lon = 67.097096f;
        LocationInfo li;
        /// <summary>
        /// Maps on Google Maps have an integer 'zoom level' which defines the resolution of the current view.
        /// Zoom levels between 0 (the lowest zoom level, in which the entire world can be seen on one map) and 
        /// 21+ (down to streets and individual buildings) are possible within the default roadmap view. 
        /// </summary>
        public int zoom = 14;
        /// <summary>
        /// not more then 640 * 640 
        /// </summary>
        public int mapWidth = 640;
        public int mapHeight = 640;

        public enum mapType { roadmap, satellite, hybrid, terrain };
        public mapType mapSelected;
        /// <summary>
        /// scale can be 1,2 for free plan and can also be 4 for paid
        /// </summary>
        public int scale;
 IEnumerator GetGoogleMap()
    {
    url = "https://maps.googleapis.com/maps/api/staticmap?center=" + lat + "," + lon +
                "&zoom=" + zoom + "&size=" + mapWidth + "x" + mapHeight + "&scale=" + scale 
                +"&maptype=" + mapSelected +
                "&markers=color:blue%7Clabel:S%7C40.702147,-74.015794&markers=color:green%7Clabel:G%7C40.711614,-74.012318&markers=color:red%7Clabel:C%7C40.718217,-73.998284&key=YourAPIKeyWillbeHere";
            loadingMap = true;
            WWW www = new WWW(url); 
            yield return www;
            loadingMap = false;
    //Assign downloaded map texture to any gameobject e.g., plane
            gameObject.GetComponent<Renderer>().material.mainTexture = www.texture;
}
 void Start()
    {

        StartCoroutine(GetGoogleMap());
    }

记住Google 不允许免费访问大于640x640 的图像。
