我如何在 NFT 铸造时披露它们？

发布于 2025-01-09 18:22:59 字数 1320 浏览 0 评论 0原文

我的目标是让我的揭示函数只在 NFT 被购买/铸造时揭示它，而不是揭示整个集合，这样人们就不必等待，但我只是继续把它搞砸。

这是我

string baseURI;
  string public baseExtension = ".json";
  uint256 public cost = 0.05 ether;
  uint256 public maxSupply = 10000;
  uint256 public maxMintAmount = 20;
  bool public paused = true;
  bool public revealed = false;
  string public notRevealedUri;
  bool public onlyWhitelisted = true;
  address[] public whitelistedAddresses;
  mapping(address => uint256) public addressMintedBalance;
  uint256 public nftPerAddressLimit = 100;
  mapping(uint256 => string) private _tokenURI;
  

  constructor(
    string memory _name,
    string memory _symbol,
    string memory _initBaseURI,
    string memory _initNotRevealedUri
  ) ERC721(_name, _symbol) {
    setBaseURI(_initBaseURI);
    setNotRevealedURI(_initNotRevealedUri);
  }

现在所掌握的内容，

function reveal() public onlyOwner {
      revealed = false;
  }

我似乎想不出一种方法可以在特定代币被铸造时改变它们的 bool 值。

我的想法是它应该位于 mint 函数本身的末尾，尽管我对此一点信心都没有。

for (uint256 i = 1; i <= _mintAmount; i++) {
      addressMintedBalance[msg.sender]++;
      _safeMint(msg.sender, supply + i);
      _tokenURI[supply].revealed = true; <-- *I know this wont work if anyone ever mints more than one at a time.*
    }

My goal is to get my reveal function to only reveal the NFT as it gets bought/minted and not reveal the whole collection so that people don't have to wait, however I just keep mucking it up.

Here is what I've got

string baseURI;
  string public baseExtension = ".json";
  uint256 public cost = 0.05 ether;
  uint256 public maxSupply = 10000;
  uint256 public maxMintAmount = 20;
  bool public paused = true;
  bool public revealed = false;
  string public notRevealedUri;
  bool public onlyWhitelisted = true;
  address[] public whitelistedAddresses;
  mapping(address => uint256) public addressMintedBalance;
  uint256 public nftPerAddressLimit = 100;
  mapping(uint256 => string) private _tokenURI;
  

  constructor(
    string memory _name,
    string memory _symbol,
    string memory _initBaseURI,
    string memory _initNotRevealedUri
  ) ERC721(_name, _symbol) {
    setBaseURI(_initBaseURI);
    setNotRevealedURI(_initNotRevealedUri);
  }

now for the reveal

function reveal() public onlyOwner {
      revealed = false;
  }

I can't seem to think of a way that would change the bool for specific tokens as they get minted.

My thought was that it should be at the end of the mint function itself, though I am not at all confident in that.

for (uint256 i = 1; i <= _mintAmount; i++) {
      addressMintedBalance[msg.sender]++;
      _safeMint(msg.sender, supply + i);
      _tokenURI[supply].revealed = true; <-- *I know this wont work if anyone ever mints more than one at a time.*
    }

您可以包含一个映射来保存您的 nfts 的显示状态。我不确定您是否只希望管理员每次都调用此显示函数，在这种情况下这样做就可以了！

....
mapping(address => mapping(uint256 => bool)) private reveals;


constructor(
string memory _name,
string memory _symbol,
string memory _initBaseURI,
string memory _initNotRevealedUri
    ) ERC721(_name, _symbol) {
    setBaseURI(_initBaseURI);
    setNotRevealedURI(_initNotRevealedUri);
}

function reveal(address _nftContract, uint256 tokenId, bool _reveal) external onlyOwner {
    bool revealed  = reveals[_nftContract][tokenId];
    require(!revealed, 'Token Already revealed');
    reveals[_nftContract][tokenId] = true;

  }

You can include a mapping to hold the reveal states of your nfts. I am not sure whether you intended only admin to call this reveal function every time, in this case this would do!

....
mapping(address => mapping(uint256 => bool)) private reveals;


constructor(
string memory _name,
string memory _symbol,
string memory _initBaseURI,
string memory _initNotRevealedUri
    ) ERC721(_name, _symbol) {
    setBaseURI(_initBaseURI);
    setNotRevealedURI(_initNotRevealedUri);
}

function reveal(address _nftContract, uint256 tokenId, bool _reveal) external onlyOwner {
    bool revealed  = reveals[_nftContract][tokenId];
    require(!revealed, 'Token Already revealed');
    reveals[_nftContract][tokenId] = true;

  }
