Unity SDK Issue

[Sebastian Maj]

Hello, I am trying to use back{4}app with Unity. I have it all set up but it won't connect or it just won't send the object. I will paste my code below, all help will be greatly appreciated.

// Use this for initialization
    void Start ()
    {
        ParseClient.Initialize(new ParseClient.Configuration {
            ApplicationId = appID,
            WindowsKey = dotnetKey,
            Server = serverURL
        });

        StartCoroutine(testObject());
    }

    // Test Function
    IEnumerator testObject()
    {
        yield return new WaitForSeconds(10.0f);

        ParseObject testObj = new ParseObject("Test");
        testObj["Testvalue"] = "Testy";
        testObj.SaveAsync();

        Debug.Log("New Object Created");
    }

All help will be greatly appreciated!

Hi, Sebastian. What is the error you have? Best.

[Sebastian Maj]

No errors just doesn't seem to be connecting or its just not creating the object. I talked to support and they said it wasn't even connecting so I guess it just didn't connect.

[Sebastian Maj]

Also the ServerURL line is this:
  private string serverURL = "https://parseapi.back4app.com/";

[Sebastian Maj]

I got a fix, I found a source code fork online and then built it within VS and imported it into unity. Here is the link: https://github.com/supersolid/Parse-SDK-dotNET/tree/release/1.7.0 When you open the .sln change it to release and mixed platform, then build it and import it into your unity project.

Very good Sebastian. Thank you for sharing to the community. I am sure it will help a lot of people.

I have the exact same issue:
- No errors reported or exceptions generated
- No connection made

I followed the link from Sebastian Maj below but that hasn't changed any behaviour and I still can't connect.

Did anyone else find a way to solve this please?

[Sebastian Maj]

So you built it the way I said above? Then you replaced it with the parse files you currently have. Then you use parse initializer behaviour script the default once and it should have an option for server url now. It works perfectly find with that. Let me know if you have any other issues with that.

Thanks for your response Sebastian.
Tried again just to be sure and you are quite right, this has solved it!
Many thanks, not sure what went wrong first time, am so pleased it is working now though!

[Sebastian Maj]

No worries, glad I could help! :)

Thanks for the help Sebastian, I was having the same issue but your solution helped. Moreover I am attaching a dll file for unity. Just import this file in your unity project and you will be good to go. Download parse.unity.dll

[Davi Macêdo]

Thank you so much for the contribution Sami!

Hi Sami,

Thank you so much! This saved my life as I couldn't run VS from my Mac. Really, life saver ;)

[nit...@digit88.com]

Hi sami...Did you use Sebastian fork to create this dll or did you just make change parse's dll? I am getting Il2cpp error on trying to build with the dll file you have put on android. I have set scriptinh backend to IL2cpp.

[Davi Macêdo]

Pls, take a look in this link here:

http://docs.back4app.com/docs/parse-migration/parse-sdk/how-to-update-parse-sdk-for-unity/

[sami...@tkxel.com]

Hello Nit,

I had used Sebastian's source code to build the .dll, and I had set scripting backend to mono2x, and it is building binary for android without any issue.

In order to see your dot net key: Sign in Back4App -> click in your app features -> core settings

Best!

Davi, 

See if you can help me:

-Already updated parse dll to latest.

-Already successfuly migrated parse.com app to back4app.com, DB is running and healthy.

-Current production app is working normally trough parse.com server.

-Problem:

While adding the "https://parseapi.back4app.com/ to serverUrl returns and error:

SecurityException: No valid crossdomain policy available to allow access

UnityEngine.WWW.get_text () (at C:/buildslave/unity/build/artifacts/EditorGenerated/Utils.cs:172)

I'm still using Unity4 as it is an old project still in production and I can't upgrade it right now.

Thanks for attention. 

[george...@gmail.com]

And obviouslly I have the crossdomain.xml on my server, since I had this app working with parse.com.

It follows:

<?xml version="1.0"?>
<cross-domain-policy>
<allow-access-from domain="georgerigato.com.br"/>
<allow-access-from domain="collabagora.com.br"/>
<allow-access-from domain="skoregame.com.br"/>
<allow-access-from domain="*.back4app.com"/>
<allow-access-from domain="*.parse.com"/>

</cross-domain-policy>

[george...@gmail.com]

Investigating, it seems my updated client can't find a crossdomain.xml on parseap.back4app.com server as this screenshot shows (right-low corner)

[casag...@back4app.com]

Hello!

It seems that Unity version does not have support with the latest version of Parse Unity SDK, so it may be the situation since the URL you've set is https://parseapi.back4app.com
Probably you'll need to upgrade your unity version in order to see if there are any other problems.

Best!

[george...@gmail.com]

Hello,

Thanks for your reply.

Upgrading the unity version of my solution seems impossible since i'm using a very specific set of packages (old NGUI for instance).

I'm hoping for a workaround for this. Any Ideas?

Best regards!

[george...@gmail.com]

Analyzing the api.parse.com that is still online, it has the crossdomain.xml on its root to allow access from unity webplayer, as the attached image shows. It's a simple solution that requires no update or recoding my solution. 

If I really have to upgrade my solution, the time needed to do so is more useful redoing all the application on another technology/architeture.

Folks as back4app.com, any position as if it will be possible to do so?

Best Regards!
