Unity seems like it came with version 3.33 LTS and when I tried to open up the project file, it threw unity-web3-spaceFPS was created with 2020.3.26f1.
I didnāt see 3.26 in the download options, so I tried to rebuild it with 3.33 and got 999 compilations error when trying to open it.
Hereās a link to download the editor:
In the process of confirming that works:
It keeps failing when Iām trying to install 2020.3.26f1.
Hey @mattjaf,
Are you having problems installing Unity 2020.3.26f1 or opening the project with 2020.3.26f1?
For everyone trying to run the project on higher versions than 2020.3.26f1 and finding the āNewtonsoftā error, do the following:
Open the manifest.json located in "unity-web3-spaceFPS\Packages"
Add newtonsoft dependency: ācom.unity.nuget.newtonsoft-jsonā: ā2.0.0ā,
So the manifest.json will look like this:
Save the file and let Unity recompile. That should fix it 
Hey, there! Great tutorial!
I got it working by following the Youtube Video, but now Iām trying changing everything to Mumbai Test. However Iām getting this NullReferenceException: Object reference not set to an instance of an object error.
Does anyone know how to fix it?
Iāve setup a Moralis Testnet Server with Polygon Mumbai EVM.
And Iāve changed the ChainID on WalletConnect component.
I tried restarting the project to use the original setup with Ethereum Mainnet and the same error is hapenning.
Iāve found out that task.Result is coming as Null in this line.
Are you on the same chain when scanning the qr code ?
and did you set the chain in wallet connect ?
Sup, 0xprof!
Yeah, Iāve set up a Moralis Server with Ethereum Mainet and used its Server URL and App Id on MoralisSetup component.
Then Iāve opened my Metamask app with an account on Ethereum Mainnet and scanned the QR Code.
The WalletConnect has the default ChainID as 1.
I tried using Trust Wallet as well, but the same error happen.
The strangest thing is that it worked the first time Iāve downloaded and configured the project. Then I tried using a Moralist Server with Mumbai Testnet and changed the URL and App Id accordingly. I also changed the WalletConnect ChainID.
The error happened so I tried reverting all changes to the first and initial config, but it stopped working throwing the same error.
Iāve just tried deleting the projectās folder and unzipping it all again, but Iām stuck with the NullReferenceException error.
This is the Dashboard logs:
did you clear the session on the wallet connect gameobject (scroll to the bottom)
and also you can clear it too from MM mobile (metamask) -> check in settings -> experimental
Yeah, Iāve been clearing sessions every time I tried something new.
I tried clearing Metameask cache and Iāve installed Trust Wallet too, which resulted in the same error.
I also noticed the following error in my logs:
Failed to retrieve server time from Moralis Server!
Because serverTimeResponse comes as Null at the following code
Dictionary<string, object> serverTimeResponse = await MoralisInterface.GetClient().Cloud.RunAsync<Dictionary<string, object>>("getServerTime", new Dictionary<string, object>());
The time on my computer and smartphone is correct.
I tried deleting, creating and restarting Moralis Servers, but it didnāt work.
Unity Version: 2020.3.33f1
Moralis Server Version: 0.0.367
@dpradell
I successfully installed the unity editor version 2020.3.33f1
it fails at like 25ish% every time i try to install 2020.3.26f1
I tried to manually add, ācom.unity.nuget.newtonsoft-jsonā: ā2.0.0ā, to the dependencies and it has an red line error saying āunexpected end of stringā.
was I suppose to open the work space in an IDE and run npm install --save [email protected] or something like that.
Hey, guys. I managed to fix my problem!
After a lot of code reading, Iāve found out that pressing āLā in the connect screen will trigger a āLogoutā function that do three things
// Disconnect wallet subscription.
await walletConnect.Session.Disconnect();
// CLear out the session so it is re-establish on sign-in.
walletConnect.CLearSession();
// Logout the Moralis User.
await MoralisInterface.LogOutAsync();
The Clear Session on WalletConnect game object just triggers walletConnect.CLearSession();, so it seems that it was not enough to solve my problem.
HI, thanks for the tutorial! It seems to me(sorry if Iām wrong, happy to be corrected) that anyone can claim the NFT from outside the game with a simple smart contract interaction. How could we solve this problem and make the claim function available only to the accounts that finished the game?
Hi @andreitoma8, youāre absolutely correct. As I say in the video, this smart contract was already deployed and used just for this sample project. Adding security to it was not the topic of this tutorial but Iāll do a video about that quite soon
@mattjaf and everyone here. I updated the sample project to 2020.3.33f1 to avoid any more confusion.
If you have that Editor version, please pull from the repo:
Or just download the updated ZIP file:
Thanks for the response @dpradell ! That sounds great, I canāt wait to see the video youāll make. Happy hacking!
Thank you, ill definitely check it out.
Hi,
I try to make a nft on opensea and replace the nft in the sample with that so far no luckā¦
simply changeing the nft data under claim nft controller on the mug wont to the job.
Hi can you look at the repo code linked above to see if youāve missed anything. What have you done in code when you say replace the nft?
Well the sample is working perfect. When I made a nft that is mintable on opensea and I replaced the 1 in turtorial with the 1 I made it wont work.
