Lets use this thread to support each other with questions regarding the Unity & Smart Contracts Project

Read instructions: Coming soon

Feel free to ask for help here - but also ensure YOU HELP people that are asking questions you know the answers to

The Moralis staff and community managers will be keeping an eye on this too

Hello, Im having a long delay between transaction confirmation and the Unity listener picking up a Mumbai testnet event, Is there a specific block confirmation number needed for Moralis to acknowledge a transaction as confirmed?

alex · May 29, 2022, 11:58pm

How long is the delay typically? Can you post your code?

leolegend · May 30, 2022, 2:06am

About 10 minutes. I am using one of the youtube tutorials:

github.com

MoralisWeb3/youtube-tutorials/blob/main/unity/unity-web3-smart-contracts/Assets/_Project/Scripts/GameManager.cs#L121


#endregion
#region PRIVATE_METHODS
private async void SubscribeToDatabaseEvents()
{
    _getEventsQuery = await Moralis.GetClient().Query<MoriaGatesEvent>();
    _queryCallbacks = new MoralisLiveQueryCallbacks<MoriaGatesEvent>();
    _queryCallbacks.OnUpdateEvent += HandleContractEventResponse;
    MoralisLiveQueryController.AddSubscription<MoriaGatesEvent>("MoriaGatesEvent", _getEventsQuery, _queryCallbacks);
}
private async UniTask<string> CallContractFunction(string inputPassword)
{
    object[] parameters = {
        inputPassword
    };

I notice that the event has a confirmed column in the database and I wont get an update on the event in unity until that value is set to true in the DB. However, not sure what the condition is for that attribute to be set.

Hoping to leverage the event functionality for my game but 10 minutes on polygon is far too slow.

Hi @leolegend, welcome to the discussion.

Is this happening with the build on WebGL? Or when testing in the Editor?

Thanks!

leolegend · May 30, 2022, 4:13pm

Webgl build running in chrome

Hi leolegend - The app works great for me without delay in the Unity Editor on my PC and running in WebGL using Chrome, but I do get the 10-12 minute delay when running on my Android phone(s). And then, when the delay is over, the MoriaGates app forcibly closes by itself. @dpradell, Do you have an idea of what could be causing this or where in the code I might look to try and debug this?

dpradell · June 12, 2022, 12:29pm

Hi @leolegend, I tested it on Editor, PC and WebGL and never waited more than 20 seconds so I couldn’t reproduce your issue. I assume you’re using MetaMask with Mumbai testnet imported?

dpradell · June 12, 2022, 12:35pm

Hi @kendev I didn’t tested it on Android so I have no idea at the moment what could be causing the issue. Not in front of computer right now but try debugging AppManager, where we listen the OnUpdateEvent from the query

kendev · June 12, 2022, 12:58pm

Ok thanks - will take a look at that and let you know if I find anything!

kendev · June 12, 2022, 2:23pm

Hi @dpradell - running in the PC environment on my computer, sometimes the app waits for 10-12 minutes before it displays the results, and sometimes it’s just a few seconds. On my Android phones, the delay is always 10-12 minutes before the app crashes. I was able to get a log on the Android phone and it’s available here: https://www.codepile.net/pile/vPDXWzPy perhaps you can spot something from these logs?

dpradell · June 13, 2022, 6:50am

Hi @kendev, thanks for the testing and the log. I will test this myself and get back to you.

kendev · June 19, 2022, 1:07pm

Hi @dpradell - did you get a chance to look into the problem on Android? I have several clients that want to see a working demonstration of both read and write smart contract access running in Android and using the Unity Web SDK. Does this exist elswhere, and with the latest web3-unity-sdk? Thanks.

dpradell · June 20, 2022, 6:59pm

Hi @kendev

I’ve been a bit busy with next project which will be AR based, built to Android. The project itself doesn’t include event listening but I will test it on that project after I release the video. This week I will let you guys know how that goes.

Cheers

kendev · June 21, 2022, 12:29am

Awesome @dpradell, and thanks very much for your time and support. I have several AR projects and prototypes running under Android including using the Nreal Light AR Smartglasses so this is wonderful news to me - Go Moralis!!!

dpradell · July 4, 2022, 4:02pm

Hi everyone. I’ve updated the the sample project to SDK 1.2.2 version. This is the repo now where I will be updating the project from now on.

And @kendev I could not replicate the issue but we’ll be looking at the behaviour of contract syncing soon so I’ll come back to you at some point.

Cheers everyone!

kendev · July 5, 2022, 3:59am

@drpadell
My troubleshooting attempts led me to clues that the Application.Quit() method was being called after the consistent 10-12 minute delay response time. So it’s possible that this is being called by a timeout of one of the SDK await methods involved during the contract syncing process? Anyway, good luck…

dpradell · July 14, 2022, 5:45am

Hey @kendev thanks for your info and your interest. We’ve been re-thinking what services we’re offering in the near future and contract syncing will be different; you won’t need the database to create the table, add the abi, etc. It will be much more efficient and easy. I don’t have an specific date for it but I know the team is fully concentrated on this.

I’ll keep up to date you guys in this forum thread

Cheers!

kendev · July 14, 2022, 5:30am

Hi @dpradell - thanks for this update and for all your fabulous work - good luck with the services upgrade and looking forward to your next update!

Go Moralis!!!
