一：使用相机截图

publicVector2 popupSize;

publicint screenshotHeight;

publicMenu2DControllermenu2DController;

publicstring postText;

protectedTexture2D_screenshot;

protectedbool _cleanupScreenshot=true;

1：使用相机正在渲染的屏幕截图

publicstaticTexture2DScreenshot{

get{

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

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

foreach(GameObjectgoinGameObject.FindGameObjectsWithTag("GUICamera")){

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

}

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

intwidth=Screen.width;

intheight=Screen.height;

Texture2Dtex=newTexture2D(width,height,TextureFormat.RGB24,false);

RenderTexturert=newRenderTexture(width,height, 24);

GameObjectwatermarkGO=GameObject.FindWithTag("Watermark");

if(watermarkGO==null){

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

}else{

//watermarkGO.SetActive(true);

}

foreach(Cameracamincameras){

RenderTexturecurrent=cam.targetTexture;

cam.targetTexture=rt;

boolenabled=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(newRect(0, 0,width,height), 0, 0 );

tex.Apply();

RenderTexture.active=null;

Object.Destroy(rt);

returntex;

}

2：获取已经几区的图片的Texture

protectedIEnumeratorShowCorutine()

{

_cleanupScreenshot=true;

_screenshot=Screenshot;

// add some delay, because taking a screenshot

// does a 'hiccup'

yieldreturnnewWaitForSeconds(0.1f);

menu2DController.HideButtons();

Popup.Paramsp =Popup.Params.Default;

p.header =LocalizationManager.GetLocalizedText(HEADER);

p.dimensions =popupSize;

p.image =_screenshot;

p.imageDimensions =newVector2(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

publicvoidOnNativeShareClick()

{

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

if(_screenshot!=null)

{

byte[]val=_screenshot.EncodeToPNG();

stringbytesString=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

publicenumLayout

{

TEXT_ONLY,

IMAGE_TEXT,

IMAGE_STATS

}

// constructor with default values

publicstaticParamsDefault

{

get{

Paramsp;

p.content ="";

p.formatContent =true;

p.header ="";

p.showCloseButton =true;

p.position =Vector3.zero;

p.dimensions =newVector2(400, 200);

p.button1text ="";

p.button2text ="";

p.button1handler =null;

p.button2handler =null;

p.button1sprite ="BtnGreen";

p.button2sprite ="BtnBlue";

p.image =null;

p.imageDimensions =newVector2(100, 100);

p.onHideEnd =null;

p.onHideStart =null;

p.layout =Layout.TEXT_ONLY;

p.layoutSprite ="";

p.layoutImageDimensions=newVector2(22,22);

p.stat1text ="";

p.stat2text ="";

p.statsSprite ="";

p.statsImageDimensions=newVector2(22,22);

returnp;

}
