Problems to Mint an NFT from Unity

[BlackDemonZyT]

Hello, i have the following problem when trying to Mint an NFT from Unity:
See the picture: https://i.imgur.com/oaLuf18.png

The users login in their wallets with:

        walletCurrent = new SolanaWalletAdapterWebGL(options, RpcCluster.MainNet, "https://api.metaplex.solana.com/", null, true);
        accountCurrent = await walletCurrent.Login();

I call the method with the following:

    public async void OnClickMint()
    {
        var signature = await ServiceFactory.Resolve<NftMintingService>().MintNftWithMetaData(
            "https://cryptodogs.fun/nfts/jsons/cryptoDogsFreeMintGolden.json",
            "CryptoDogs Free Mint | Golden", "CDFMG");
    }

And this is the code for NftMintingService.cs which i touched the initial parts of it so i could integrate it with the wallet login from MagicBlock SDK:

        public async Task<string> MintNftWithMetaData(string metaDataUri, string name, string symbol, Action<bool> mintDone = null)
        {
            //var walletHolderService = ServiceFactory.Resolve<WalletHolderService>();
            var wallet = ConnectWallet.walletCurrent;
            var rpcClient = ConnectWallet.walletCurrent.ActiveRpcClient;

            Account mintAccount = new Account();
            Account tokenAccount = new Account();

            var fromAccount = ConnectWallet.walletCurrent.Account;

            Debug.Log("KEYBITES");
            Debug.Log(ConnectWallet.walletCurrent.Account.PrivateKey.KeyBytes.Length);

            // To be able to sign the transaction while using the transaction builder we need to have a private key set in the signing account. 
            // TODO: I will try to make this nicer later. 
            //fromAccount = new Account(ConnectWallet.walletCurrent.Account.PrivateKey.KeyBytes,
                //ConnectWallet.walletCurrent.Account.PublicKey.KeyBytes);

            RequestResult<ResponseValue<ulong>> balance =
                await rpcClient.GetBalanceAsync(wallet.Account.PublicKey, Commitment.Confirmed);

            // TODO: Check if there is enough sol in the wallet to mint. 
            if (balance.Result != null && balance.Result.Value < SolanaUtils.SolToLamports / 10)
            {
                LoggingService.Log("Sol balance is low. Minting may fail", true);
            }

            Debug.Log($"Balance: {balance.Result.Value} ");
            Debug.Log($"Mint key : {mintAccount.PublicKey} ");

            var blockHash = await rpcClient.GetRecentBlockHashAsync();
            var rentMint = await rpcClient.GetMinimumBalanceForRentExemptionAsync(
                TokenProgram.MintAccountDataSize,
                Commitment.Confirmed
            );
            var rentToken = await rpcClient.GetMinimumBalanceForRentExemptionAsync(
                TokenProgram.TokenAccountDataSize,
                Commitment.Confirmed
            );

            Debug.Log($"Token key : {tokenAccount.PublicKey} ");

            //2. create a mint and a token
            var createMintAccount = SystemProgram.CreateAccount(
                fromAccount,
                mintAccount,
                rentMint.Result,

Hey, yeah sorry i didnt get to upgrade it to the new unity sdk version. You already found out you dont need to change the private key in fromAccount anymore and that metadatav2 doesnt exist anymore. 👍
Maybe check the meta data if its correct or try metadata v3. Also check if your name and symbol are not too long. You could also check if puffmetadata is still needed.

[BlackDemonZyT]

Hi! How can i specify to use metadatav3 in my code? I do not understand 😅

[BlackDemonZyT]

Hello, do you have Whatsapp, telegram or Discord in order to comunicate quickly? My project is pretty big and i need urgent help.

[Woody4618]

Hey did you check the name and symbol length? There is a max limit on name length.

In general its probably better to ask in the magic block sdk repo now, since i dont have much time to maintain the solplay sdk and its behind in the sdk version.

This code here I just tested and it works using magic block unity sdk version 0.1.0:
Its not creating a master edition. But not sure if you need it. Depends on what you plan to do.

Doesnt seem to work with wallet adapter though for some reason only with ingame wallet. Ill write the magic block devs.

Alright, i appreciate your help, i hope it gets fixed soon, there are people waiting for me xD

Hey, its fixed in Unity SDK version 0.1.1 please update and this is the updated mint code:
