基于steamworks获取steam用户头像

查看官网api，使用c++写的，转成c#之后，有个问题就是，图片显示问题

我们可以获取到一个含有图片信息的byte[]

然后

private Texture2D downloadedAvatar;
public RawImage image;

downloadedAvatar = new Texture2D((int) width, (int) height, TextureFormat.RGBA32, false);
                    downloadedAvatar.LoadRawTextureData(avatarStream);
                    downloadedAvatar.Apply();

                    image.texture = downloadedAvatar;

Texture2D先load，然后Apply就行了

【完整源码】

    IEnumerator _FetchAcatar(CSteamID id, RawImage ui)
    {
        //获取中等图片，如果获取的是大图片的话，可能获取不到
        var AvatarInt = SteamFriends.GetMediumFriendAvatar(id);
        Debug.Log("AvatarInt" + AvatarInt);
        while (AvatarInt == -)
        {
            yield return null;
        }
        if (AvatarInt > )
        {
            SteamUtils.GetImageSize(AvatarInt, out width, out height);

            if (width >  && height > )
            {
                byte[] avatarStream = new byte[ * (int)width * (int)height];
                SteamUtils.GetImageRGBA(AvatarInt, avatarStream,  * (int)width * (int)height);

                downloadedAvatar = new Texture2D((int)width, (int)height, TextureFormat.RGBA32, false);
                downloadedAvatar.LoadRawTextureData(avatarStream);
                downloadedAvatar.Apply();

                ui.texture = downloadedAvatar;
            }
        }
    }
