一：使用相机截图

public Vector2 popupSize;

public int screenshotHeight;

public Menu2DController menu2DController;

public string postText;

protected Texture2D _screenshot;

protected bool _cleanupScreenshot = true ;

1：使用相机正在渲染的屏幕截图

publicstaticTexture2DScreenshot{

get{

List<Camera > cameras = new List <Camera>();

cameras.Add (GameObject. FindGameObjectWithTag("MainCamera" ).GetComponent< Camera>());

foreach (GameObject go in GameObject.FindGameObjectsWithTag ("GUICamera")){

cameras.Add (go.GetComponent< Camera>());

}

cameras.Sort ((x, y) => x.depth .CompareTo( y.depth ));

int width = Screen. width;

int height = Screen. height;

Texture2D tex = new Texture2D( width, height , TextureFormat. RGB24, false );

RenderTexture rt = new RenderTexture( width, height , 24);

GameObject watermarkGO = GameObject. FindWithTag("Watermark" );

if (watermarkGO == null){

Debug.LogError ("No watermark found!");

} else{

//watermarkGO.SetActive(true);

}

foreach (Camera cam in cameras){

RenderTexture current = cam.targetTexture;

cam.targetTexture = rt;

bool enabled = cam.enabled;

cam.enabled = true;

cam.Render ();

cam.enabled = enabled;

cam.targetTexture = current;

}

if (watermarkGO != null){

//watermarkGO.SetActive(false);

}

RenderTexture.active = rt;

// Read render texture contents into the texture

tex.ReadPixels ( new Rect(0, 0, width, height ), 0, 0 );

tex.Apply ();

RenderTexture.active = null;

Object.Destroy (rt);

return tex ;

}

2：获取已经几区的图片的Texture

protected IEnumerator ShowCorutine()

{

_cleanupScreenshot = true ;

_screenshot = Screenshot;

// add some delay, because taking a screenshot

// does a 'hiccup'

yield return new WaitForSeconds (0.1f);

menu2DController.HideButtons ();

Popup.Params p = Popup.Params .Default;

p.header = LocalizationManager.GetLocalizedText (HEADER);

p.dimensions = popupSize;

p.image = _screenshot;

p.imageDimensions = new Vector2 (Screen. width / (float )Screen. height * screenshotHeight, screenshotHeight );

p.onHideEnd = HandlePopupHideEnd;

p.button1text = LocalizationManager. GetLocalizedText (SHARE_IT );

p.button1handler = OnNativeShareClick;

p.onHideStart = menu2DController. ShowButtons;

Popup.Instance .Show (p);

}

3：将已经截图的texture 图片使用字符串进行传输

public void OnNativeShareClick()

{

//Debug.LogError("XXXXX ShareWebChat");

if (_screenshot != null)

{

byte[] val = _screenshot. EncodeToPNG();

string bytesString = System. Convert.ToBase64String (val);

AriesGame.Instance .WeChatShare( bytesString);

}

else

{

Debug.LogError ("XXXXX _screenshot = null !!!!!!!!!!!!! ");

}

//SPShareUtility.ShareMedia ("Kickerinho", GetDescription (), _screenshot);

}

ps：Popup.Params 是一个弹出框可以做一个弹出框的预制件

// constructor with default values

public enum Layout

{

TEXT_ONLY,

IMAGE_TEXT,

IMAGE_STATS

}

// constructor with default values

public static Params Default

{

get{

Params p ;

p.content = "";

p.formatContent = true;

p.header = "";

p.showCloseButton = true;

p.position = Vector3.zero ;

p.dimensions = new Vector2 (400, 200);

p.button1text = "";

p.button2text = "";

p.button1handler = null;

p.button2handler = null;

p.button1sprite = "BtnGreen";

p.button2sprite = "BtnBlue";

p.image = null;

p.imageDimensions = new Vector2 (100, 100);

p.onHideEnd = null;

p.onHideStart = null;

p.layout = Layout.TEXT_ONLY ;

p.layoutSprite = "";

p.layoutImageDimensions = new Vector2(22,22);

p.stat1text = "";

p.stat2text = "";

p.statsSprite = "";

p.statsImageDimensions = new Vector2(22,22);

return p ;

}
