Having small issue here with Unity and NGUI. NGUI has UITexture as its main texture such as Unity has GUITexture.
I sent a request to facebook to get the users profile image which sends back a perfect url which if I put in the browser works fine.
My issue is taking that Texture2D (Facebook API does it as a Texture2D) and putting it on my UITexture. For some reason it just does not take it correctly. I keep getting a null value for it. I am also using Mobile Social as well from the asset store any help, helps.
Here is my snippet of code.
private void UserDataLoaded(FB_Result result)
{
SPFacebook.OnUserDataRequestCompleteAction -= UserDataLoaded;
if (result.IsSucceeded)
{
Debug.Log("User Data Loaded!");
IsUserInfoLoaded = true;
string FBNametxt = SPFacebook.Instance.userInfo.Name;
UILabel Name = GameObject.Find("FBName").GetComponent<UILabel>();
Name.text = FBNametxt;
Texture2D FBLoadTex = SPFacebook.Instance.userInfo.GetProfileImage(FB_ProfileImageSize.normal);
FBGetProfile.GetComponent<UITexture>().mainTexture = FBLoadTex != null ? FBLoadTex : PlaceHolderImg;
}
else {
Debug.Log("User data load failed, something was wrong");
}
}
The placeholder image is just a already selected image used if the fbprofile pic does is null. Which I keep getting.....
It's possible you're looking for RawImage which exist for this purpose
http://docs.unity3d.com/Manual/script-RawImage.html
Since the Raw Image does not require a sprite texture, you can use it to display any texture available to the Unity player. For example, you might show an image downloaded from a URL using the WWW class or a texture from an object in a game.
Use Unity.UI and use that feature.
Add "Ngui Unity2d Sprite" component instead of UiTexture to your profile picture in editor and use below code in your Fb callback
private void ProfilePicCallBack (FBResult result)
{
if (result.Error != null) {
Debug.Log ("Problem with getting Profile Picture");
return;
}
ProfileImage.GetComponent<UI2DSprite> ().sprite2D = Sprite.Create(result.Texture, new Rect(0,0,128,128), new Vector2(0,0));
}
there might be an another way to do this. but this worked for me

I have seen that there are more answers to similar questions, but none of these helped me. I hope you can.
I have a Unity2D shooter game and I try to make a menu for UNET. I watched a youtube tutorial from Brackeys to make the menu (https://youtu.be/V4oRs26vAw8?list=PLPV2KyIb3jR5PhGqsO7G4PsbEC_Al-kPZ&t=896) and when he runs the project it shows me the error: "error CS0122: 'UnityEngine.Networking.Match.ListMatchResponse' is inaccessible due to its protection level. I found out that this might happen when you access for example a private variable from another function, but I access a function from Unity and I can not modify its type (I believe). Any ideas? Thank you.
public void OnMatchList(bool success, string extendedInfo, ListMatchResponse matchList)
{
status.text = "";
if (matchList == null)
{
status.text = "Couldn't get room list.";
return;
}
ClearRoomList();
foreach(MatchDesc match in matchList.matches)
{
GameObject _roomListItemGO = Instantiate(roomListItemPrefab);
_roomListItemGO.transform.SetParent(roomListParent);
// Have a component sit on the gameobject
// that will take care of setting up the name / amount of users.
// as well as setting up a callback function that will join the game.
roomList.Add(_roomListItemGO);
}
}
'MatchDesc' has been renamed to 'MatchInfoSnapshot'.
Just replace it and it should work fine.
I have an array of prefabs i want to show a preview of in my custom editor. This works for gameobjects with a mesh renderer, for example the basic quad. However when i try to use AssetPreview.GetAssetPreview(tilePrefab.gameObject); on gameobject with a UnityEngine.UI.Image and a canvas renderer it always returns null.
Below is the part of the code that draws the previews.
public class MapEditor : Editor
{
public override void OnInspectorGUI()
{
for (int prefabIndex = 0; prefabIndex < TileSet.TilePrefabs.Count; prefabIndex++)
DrawIconTexture(prefabIndex, columnCount);
}
private void DrawIconTexture(int prefabIndex, int columnCount)
{
TileBehaviour tilePrefab = TileSet.TilePrefabs[prefabIndex];
Texture iconTexture = AssetPreview.GetAssetPreview(tilePrefab.gameObject);
Rect iconRect = GetIconRect(prefabIndex, columnCount);
if (iconTexture != null)
GUI.DrawTexture(iconRect, iconTexture);
else if (AssetPreview.IsLoadingAssetPreview(tilePrefab.gameObject.GetInstanceID()))
Repaint();
}
}
I know GetAssetPreview loads assets async, that is solved by the repaint. I have also tried
while(iconTexture == null)
iconTexture = AssetPreview.GetAssetPreview(tilePrefab.gameObject);
But that never finishes.
I also tried to use the texture of the Image
if (iconTexture == null)
iconTexture = tilePrefab.GetComponent<Image>().sprite.texture;
But that does not work because the sprite is in an atlas and all of the atlas is shown.
Edit: misread the question. I actually tried to use IsLoadingAssetPreview and IsLoadingAssetPreviews for few hours, without success. I ended up using a sad little trick
if (_previews.All(pair => pair.Value != null)) return;
_previews = GeneratePreviews();
I put that in the Update() loop of my EditorWindow. It's pretty hacky, I'm going to ask Unity if the AssetPreview methods are actually working.
Old answer, irrelevant:
You are not using the while loop and GetAssetPreview correctly.
GetAssetPreview will launch an asynchronous loading of the preview. To know if the preview is fully loaded you need to call AssetPreview.IsLoadingAssetPreview.
A pretty simple and brutal way of doing it (it will block execution) is :
var preview = AssetPreview.GetAssetPreview(item);
while (AssetPreview.IsLoadingAssetPreview(item.GetInstanceID())) {
// Loading
}
As usual, careful with while loops. Note that there is also a AssetPreview.IsLoadingAssetPreviews method with no parameters.
you should just use "using UnityEditor"
I'm entirely unfamiliar with Unity3D's more complex feature set and am curious if it has the capability to take a picture and then manipulate it. Specifically my desire is to have the user take a selfie and then have them trace around their face to create a PNG that would then be texture mapped onto a model.
I know that the face mapping onto a model is simple, but I'm wondering if I need to write the photo/carving functionality into the encompassing Chrome app, or if it can all be done from within Unity. I don't need a tutorial on how to do it, just asking if it's something that is possible.
Yes, this is possible. You will want to look at the WebCamTexture functionality.
You create a WebCamTexture and call its Play() function which starts the camera. WebCamTexture, as any Texture, allows you to get the pixels via a GetPixels() call. This allows you to take a snapshot in when you like, and you can save this in a Texture2D. A call to EncodeToPNG() and subsequent write to file should get you there.
Do note that the code below is a quick write-up based on the documentation. I have not tested it. You might have to select a correct device if there are more than one available.
using UnityEngine;
using System.Collections;
using System.IO;
public class WebCamPhotoCamera : MonoBehaviour
{
WebCamTexture webCamTexture;
void Start()
{
webCamTexture = new WebCamTexture();
GetComponent<Renderer>().material.mainTexture = webCamTexture; //Add Mesh Renderer to the GameObject to which this script is attached to
webCamTexture.Play();
}
IEnumerator TakePhoto() // Start this Coroutine on some button click
{
// NOTE - you almost certainly have to do this here:
yield return new WaitForEndOfFrame();
// it's a rare case where the Unity doco is pretty clear,
// http://docs.unity3d.com/ScriptReference/WaitForEndOfFrame.html
// be sure to scroll down to the SECOND long example on that doco page
Texture2D photo = new Texture2D(webCamTexture.width, webCamTexture.height);
photo.SetPixels(webCamTexture.GetPixels());
photo.Apply();
//Encode to a PNG
byte[] bytes = photo.EncodeToPNG();
//Write out the PNG. Of course you have to substitute your_path for something sensible
File.WriteAllBytes(your_path + "photo.png", bytes);
}
}
For those trying to get the camera to render live feed, here's how I managed to pull it off. First, I edited Bart's answer so the texture would be assigned on Update rather than just on Start:
void Start()
{
webCamTexture = new WebCamTexture();
webCamTexture.Play();
}
void Update()
{
GetComponent<RawImage>().texture = webCamTexture;
}
Then I attached the script to a GameObject with a RawImage component. You can easily create one by Right Click -> UI -> RawImage in the Hierarchy in the Unity Editor (this requires Unity 4.6 and above). Running it should show a live feed of the camera in your view. As of this writing, Unity 5 supports the use of webcams in the free personal edition of Unity 5.
I hope this helps anyone looking for a good way to capture live camera feed in Unity.
It is possible. I highly recommend you look at WebcamTexture Unity API. It has some useful functions:
GetPixel() -- Returns pixel color at coordinates (x, y).
GetPixels() -- Get a block of pixel colors.
GetPixels32() -- Returns the pixels data in raw format.
MarkNonReadable() -- Marks WebCamTexture as unreadable
Pause() -- Pauses the camera.
Play() -- Starts the camera.
Stop() -- Stops the camera.
Bart's answer has a required modification. I used his code and the pic I was getting was black. Required modification is that we have to
convert TakePhoto to a coroutine and add
yield return new WaitForEndOfFrame();
at the start of Coroutine. (Courtsey #fafase)
For more details see
http://docs.unity3d.com/ScriptReference/WaitForEndOfFrame.html

Take photo using webcam is giving black output[Unity3D]
Yes, You can. I created Android Native camera plugin that can open your Android device camera, capture image, record video and save that in the desired location of your device with just a few lines of code.
you need to find your webcam device Index by search it in the devices list and select it for webcam texture to play.
you can use this code:
using UnityEngine;
using System.Collections;
using System.IO;
using UnityEngine.UI;
using System.Collections.Generic;
public class GetCam : MonoBehaviour
{
WebCamTexture webCam;
string your_path = "C:\\Users\\Jay\\Desktop";// any path you want to save your image
public RawImage display;
public AspectRatioFitter fit;
public void Start()
{
if(WebCamTexture.devices.Length==0)
{
Debug.LogError("can not found any camera!");
return;
}
int index = -1;
for (int i = 0; i < WebCamTexture.devices.Length; i++)
{
if (WebCamTexture.devices[i].name.ToLower().Contains("your webcam name"))
{
Debug.LogError("WebCam Name:" + WebCamTexture.devices[i].name + " Webcam Index:" + i);
index = i;
}
}
if (index == -1)
{
Debug.LogError("can not found your camera name!");
return;
}
WebCamDevice device = WebCamTexture.devices[index];
webCam = new WebCamTexture(device.name);
webCam.Play();
StartCoroutine(TakePhoto());
display.texture = webCam;
}
public void Update()
{
float ratio = (float)webCam.width / (float)webCam.height;
fit.aspectRatio = ratio;
float ScaleY = webCam.videoVerticallyMirrored ? -1f : 1f;
display.rectTransform.localScale = new Vector3(1f, ScaleY, 1f);
int orient = -webCam.videoRotationAngle;
display.rectTransform.localEulerAngles = new Vector3(0, 0, orient);
}
public void callTakePhoto() // call this function in button click event
{
StartCoroutine(TakePhoto());
}
IEnumerator TakePhoto() // Start this Coroutine on some button click
{
// NOTE - you almost certainly have to do this here:
yield return new WaitForEndOfFrame();
// it's a rare case where the Unity doco is pretty clear,
// http://docs.unity3d.com/ScriptReference/WaitForEndOfFrame.html
// be sure to scroll down to the SECOND long example on that doco page
Texture2D photo = new Texture2D(webCam.width, webCam.height);
photo.SetPixels(webCam.GetPixels());
photo.Apply();
//Encode to a PNG
byte[] bytes = photo.EncodeToPNG();
//Write out the PNG. Of course you have to substitute your_path for something sensible
File.WriteAllBytes(your_path + "\\photo.png", bytes);
}
}
There is a plugin available for this type of functionality called Camera Capture Kit - https://www.assetstore.unity3d.com/en/#!/content/56673 and while the functionality provided is geared towards mobile it contains a demo of how you can use the WebCamTexture to take a still image.
If you want to do that without using a third party plugin then #FuntionR solution will help you. But, if you want to save the captured photo to the gallery (Android & iOS)then it's not possible within unity, you have to write native code to transfer photo to gallery and then call it from unity.
Here is a summarise blog which will guide you to achieve your goal.

Edit: Note that, the above thread describes image picking from the gallery, but the same process will be for saving the image to the gallery.
I have a problem with posting screenshot to FB. Connection is not the problem because I collect, deserialize and show my fb data. Post score and message to friend work fine but I cannot manage to post a shot from my phone. I am using Eclipse for debugging but I don't get any errors. My code look like this:
`
IEnumerator TakeScreenShot()
{
//coroutine because I want to wait until end of the frame for shot
yield return new WaitForEndOfFrame();
//create new texture that will be my screenshot
Texture2D tex = new Texture2D(Screen.width,Screen.height,TextureFormat.RGB24, false);
// read pixels from screen
tex.ReadPixels(new Rect(0,0,Screen.width,Screen.height),0,0);
//and apply them to texture
tex.Apply();
// now we have screenshot
// now we need to encode texture to array of bytes
byte[] buffer = tex.EncodeToPNG();
//so we can save it to storage
// System.IO.File.WriteAllBytes(Application.dataPath + "/screenshots/screen/screen" + ".png", buffer);
//or to convert it to string for posting to facebook
string s = Convert.ToBase64String(buffer);
//????? maybe my string format is not correct
var query = new Dictionary<string, string>();
query["photos"] = s;
FB.API("me?fields=photos",Facebook.HttpMethod.POST, delegate (string r) { ; }, query);
}
`
when I go to GraphExplorer and paste command "me?fields=photos" I get nothing. It means function did nothing. I forgot to say that i granted permission for user_photos. This is frustrating. I have lost three days on problem that looked trivial, and yet no solution in sight. I will appreciate any suggestions.
Right now there's no easy way to handle this through FB.API since it takes in a Dictionary<string, string>.
However FB.API() is really just a wrapper around Unity's WWW class. You can call the graph endpoints at graph.facebook.com and pass in the byte[] buffer = tex.EncodeToPNG() as a param in WWWForm().
UPDATE: FB.API() has been updated in version 4.3.3 to support WWWForm as well. You can now upload photos via that method now.
I am very new to Unity3d.
I have a JSON array that contains the parameters of the prefabs I want to create at runtime.
I want to display images that are stored on my server in the scene.
I have a prefab "iAsset" that has a plane (mesh filter) and I want to load the image files as the texture of the plane.
I am able to Instatiate the prefabs however the prefab is showing up as a white square. This is my code:
for(var i = 0; i < bookData.Assets.Count; i++){
GameObject newAsset = null;
newAsset = (GameObject)Instantiate(iasset, new Vector3(2*i, 0, 0), Quaternion.identity);
if(!imageAssetRequested )
{
remoteImageAsset = new WWW(((BookAssets)bookData.Assets[i]).AssetContent);
imageAssetRequested = true;
}
if(remoteImageAsset.progress >=1)
{
if(remoteImageAsset.error == null)
{
loadingRemoteAsset = false;
newAsset.renderer.material.mainTexture = remoteImageAsset.texture;
}
}
}
the urls to the images on my server is retrieved from the JSON array:
((BookAssets)bookData.Assets[i]).AssetContent);
The code builds without any errors, I would very much appreciate any help to display the remote images.
You are not waiting for your downloads to complete.
The WWW class is asynchronous, and will commence the download. However, you need to either poll it (using the code you do have above) at a later time, or use a yield WWW in a CoRoutine that will block your execution (within that CoRoutine) until the download finishes (either successfully or due to failure).
Refer to Unity Documentation for WWW
Note however, that page sample code is wrong, and Start is not a CoRoutine / IEnumarator. Your code would look something like :
void Start()
{
... your code above ...
StartCoroutine(DownloadImage(bookData.Assets[i]).AssetContent, newAsset.renderer.material.mainTexture));
}
IEnumerator DownloadImage(string url, Texture tex)
{
WWW www = new WWW(url);
yield return www;
tex.LoadImage(www.bytes)
}
