Be aware: By default, the Unity NFT minter makes use of our good contract and metadata, which implies you’ll be minting the Moralis emblem. As such, we have to present you tips on how to use Unity NFT minter for different good contracts and metadata.
Mint Unity NFT Tokens Utilizing Your Sensible Contracts and Metadata URLs
The minting panel represents the core of our Unity NFT minter. The latter is activated as quickly as you join your pockets as displayed within the demo:
Wanting on the screenshot above, you may see the good contract’s knowledge and NFT metadata fields. It is advisable to populate these fields along with your good contract and metadata particulars to make use of this dapp to mint any NFTs you need. So, these are the small print you want:
- For good contract: handle, ABI, and contract operate
- Metadata URL
Thankfully, you may simply acquire these particulars. Each programmable blockchain has its explorer, and that is the place the entire above particulars relating to all deployed Web3 contracts await you. In our case, we’re utilizing Polygon’s testnet, Mumbai. Therefore, PolygonScan (Mumbai) is the explorer we have to make the most of.
Alternatively, so far as the metadata URL goes, there are numerous methods to go about it. In an effort to do that in a decentralized method, we advocate utilizing decentralized cloud storage providers. Once more, there are a number of respected choices accessible; nevertheless, we advocate utilizing IPFS. Furthermore, Moralis additionally integrates IPFS, which implies you may seamlessly work with this storage resolution. When you add Unity property to IPFS, you get your metadata URL.
Minting Panel Script Walkthrough
For an in depth code walkthrough, watch the video on the backside of this text, beginning at 9:41. Nonetheless, we wish to briefly have a look at the principle operate of our minter dapp, “MintNft()”, which is named by the “mint” button:
public async void MintNft()
{
if (contractAddress == string.Empty || contractAbi == string.Empty || contractFunction == string.Empty)
{
Debug.LogError("Contract knowledge will not be totally set");
return;
}
if (metadataUrl == string.Empty)
{
Debug.LogError("Metadata URL is empty");
return;
}
statusText.textual content = "Please affirm transaction in your pockets";
mintButton.interactable = false;
var consequence = await ExecuteMinting(metadataUrl);
if (result's null)
{
statusText.textual content = "Transaction failed";
mintButton.interactable = true;
return;
}
// We inform the GameManager what we minted the merchandise efficiently
statusText.textual content = "Transaction accomplished!";
Debug.Log($"Token Contract Deal with: {contractAddress}");
Debug.Log($"Token ID: {_currentTokenId}");
// Activate OpenSea button
mintButton.gameObject.SetActive(false);
openSeaButton.gameObject.SetActive(true);
}The code above checks that you simply’ve supplied particulars and metadata URL from a sensible contract. If any particulars are lacking, the operate logs a corresponding error. Nonetheless, if all particulars are supplied, the “MintNft” operate returns the “Please affirm the transaction in your pockets” message and triggers the minting motion. The latter is completed with the “ExecuteMinting” operate, which is the place we use the facility of Moralis.
The “ExecuteMinting” Perform and the Energy of Moralis
Right here’s the “ExecuteMinting” operate:
personal async UniTask<string> ExecuteMinting(string tokenUrl)
{
// Dummy TokenId primarily based on present time.
lengthy currentTime = DateTime.Now.Ticks;
_currentTokenId = new BigInteger(currentTime);
// These are the parameters that the contract operate expects
object[] parameters = {
_currentTokenId.ToString("x"), // That is the format the contract expects
tokenUrl
};
// Set fuel configuration. When you set it at 0, your pockets will use its default fuel configuration
HexBigInteger worth = new HexBigInteger(0);
HexBigInteger fuel = new HexBigInteger(0);
HexBigInteger gasPrice = new HexBigInteger(0);
string resp = await Moralis.ExecuteContractFunction(contractAddress, contractAbi, contractFunction, parameters, worth, fuel, gasPrice);
return resp;
}As you may see above, the operate takes within the supplied metadata URL, which is now known as “tokenURL”. Then, the operate creates a token ID. Subsequent, it makes use of that ID to create token parameters that the good contract expects.
Be aware: We used an ERC-721 contract (for extra particulars, use the video under at 12:50). When you had been to make use of an ERC-1155 contract, you’d have to tweak the code.
Subsequent, the “ExecuteMinting” operate units fuel configuration. Lastly, due to Moralis, a single line of code takes care of minting through the “ExecuteContractFunction” operate.
Utilizing PolygonScan to Get hold of Sensible Contracts’ Particulars
Beginning at 12:50 within the video under, you may see our good contract on PolygonScan. It’s a fairly easy contract primarily based on a verified OpenZeppelin template. At 13:42, you may see the place to acquire your contract’s handle, which it is advisable to paste into the Unity minter. Subsequent, the video additionally exhibits you the place to get your contract’s ABI:
Moreover, additionally be certain to vary the title of your good contract’s operate (14:13):
Be aware: When deploying good contracts utilizing instruments similar to Remix or Hardhat, you’re going to get good contracts when you deploy them. Nonetheless, as proven above, you may all the time entry these particulars in blockchain explorers.
Right here’s the video tutorial we’ve been referencing above. It contains all the small print you want about our Unity NFT minter dapp:
