Ethereum Unity3D Boilerplate Questions

@vivraan

Well the problem with using the same server for cloud functions on different apps persists (returning an error related to the session token), even though you mentioned you’re not able to reproduce it on your end.

@dgoodrich I’ll update to 1.0.4 and test. Making this a UPM package will mean that all external dependencies such as UniTask can be downloaded separately.

Ethereum Unity3D Boilerplate Questions

@dgoodrich I had posted a comment a while back on YouTube where you introduced the Unity package. There I’d said this: I’d really appreciate if the Moralis package was compatible with UPM for convenience. The Example directory could be part of Example Assets deployed once the package is installed. This also makes it easier to clone the project once and simply update by pulling from a stable branch or commit every time a release is available, and having the package included from the Package Man…

Yes. In the YouTube video introducing the boilerplate, you mentioned that Example can be safely removed/not imported while the others are required. However, at the moment this is not the case. From the looks of it those contents should be in the DLLs folder. Apart from UniTask, no, I added a bunch of asmdefs myself because the code I work with uses them extensively. Specifically, I added an asmdef in each of these folders: Moralis, WalletConnectSharp\WalletConnectSharp.Core, WalletConnectSh…

Please make this repo UPM compatible so that updates don’t break existing code samples. I like the approach of using a Git URL better than using the Asset Store. That way I can more easily connect my existing UPM infrastructure and I don’t have to download the SDK on every single project I work on, instead either referring to the Git repo or a local clone. Until this change is made I will eschew downloading .unitypackages of new versions because reworking the updates in my private UPM package …

This is a non-issue with UPM. Just refer to the package depending on com.unity.textmeshpro and you’re golden.

Has MoralisInterface.cs been moved to the top level of the directory?

Anyway nothing has changed, I still get this error when I use a different app to access a Cloud Function on my Moralis Server instance:

2022-02-11T09:45:47.880Z - Error: Invalid session token
    at Object.getAuthForSessionToken (/moralis-server/lib/Auth.js:114:11)
    at runMicrotasks (<anonymous>)
    at processTicksAndRejections (node:internal/process/task_queues:96:5)

I’m also still getting a NullReferenceException when I try to log out, both manually and when it is triggered through Application.quitting.

Long back I was able to use the API Console for a specific user but nowadays it doesn’t work either.

This old error did not appear in one project but appeared in another even when both are using .NET Standard 2.0:

D:\dev\Banzan\UltraCore\MoralisWeb3ApiSdk\Moralis\Moralis.WebGL\Moralis.SolanaApi\Client\ApiClient.cs(154,20): error CS0103: The name 'HttpUtility' does not exist in the current context

@vivraan,

Are you comfortable sharing your Cloud Function code?

Thanks,

David

[dgoodrich]

Also, have you posted the cloud function question and code in a forum channel for cloud functions?

[vivraan]

No, not yet I’m afraid. I decidedly stuck here since I was usually using Unity for this, and because I suspect it’s not a problem with Cloud Functions.

@dgoodrich

Are you comfortable sharing your Cloud Function code?

I’ll confirm with my boss just to be sure. Please send me your GitHub/GitLab email address privately.

I had to release a critical update this afternoon. Authentication now requires server Time be included in the message being signed.

The change was made in the MainMenuScript.cs file of the Demo

    public async void WalletConnectHandler(WCSessionData data)
    {
        Debug.Log("Wallet connection received");
        // Extract wallet address from the Wallet Connect Session data object.
        string address = data.accounts[0].ToLower();
        string appId = MoralisInterface.GetClient().ApplicationId;
        long serverTime = 0;

        // Retrieve server time from Moralis Server for message signature
        Dictionary<string, object> serverTimeResponse = await MoralisInterface.GetClient().Cloud.RunAsync<Dictionary<string, object>>("getServerTime", new Dictionary<string, object>());

        if (serverTimeResponse == null || !serverTimeResponse.ContainsKey("dateTime") ||
            !long.TryParse(serverTimeResponse["dateTime"].ToString(), out serverTime))
        {
            Debug.Log("Failed to retrieve server time from Moralis Server!");
        }

        Debug.Log($"Sending sign request for {address} ...");

        string signMessage = $"Moralis Authentication\n\nId: {appId}:{serverTime}";
        string response = await walletConnect.Session.EthPersonalSign(address, signMessage);

        Debug.Log($"Signature {response} for {address} was returned.");

        // Create moralis auth data from message signing response.
        Dictionary<string, object> authData = new Dictionary<string, object> { { "id", address }, { "signature", response }, { "data", signMessage } }; 

        Debug.Log("Logging in user.");

        // Attempt to login user.
        MoralisUser user = await MoralisInterface.LogInAsync(authData);

        if (user != null)
        {
            Debug.Log($"User {user.username} logged in successfully. ");
        }
        else
        {
            Debug.Log("User login failed.");
        }

        HideWalletSelection();
    }

The newest release (v1.0.5) has this patch.

[vivraan]

Ah shucks, need to do the whole update process again 🥲

[dgoodrich]

Why not just that block of code?

[vivraan]

Is it just that code that’s changed? Well in that case, sure!

[dgoodrich]

That is it, added code to retrieve the server time and add it to the message being signed. No other changes needed.

i receive UriFormatException from version 1.05 when login using walletconnect via WebGl. version 1.04 working fine. pls help tq

[Wagan]

Hi @enoonmai. I am having the same problem as it was saving my class ACL as “Master Key Only” I set my PublicReadAccess = true and PublicWriteAccess, but I was still getting “Master Key Only”. Have you figured out the solution for this?

[YosephKS]

Awesome @dgoodrich

[whitegreenstudios88]

Hi, thanks for your solution, I able to run photon 2 in WebGL. but i have problem with player swapping controller. when one player in the room, the playercontroller is working, but when second player join the room, the player 1 control player 2 while player 2 control player 1. Do u hav the same problem? TQ

[caiocabralbr]

You have to verify the authority of the player
Use photonView.isMine to do this
If true, you can use and move the player
If false, you can’t
This is the basic logic for multiplayer

[vivraan]

Would make a lot of sense as a new thread.

[dgoodrich]

I do note receive the same error. Please double check the fields in your MoralisSetup Controller. Look to see that both Server Uri and RPC Node Uri are set from the values on your Moralis Server.
**

**

If this values are set, does the same error happen if you run it in the IDE? If so please copy the text of the exception and post it.

Regards,

David

[whitegreenstudios88]

TQ, missing the Rpc node, all working now

[overmoral]

where do I find this Rpc Node URI? I have Server URL and AppID, but where is this from?

[dgoodrich]

In the Admin Panel of you Moralis Server click on Speedy Nodes:

Then click on the “Endpoints” button of the target chain. Choose the URI of the endpoint you want to send Web3 requests to.

Regards,

David
