ERC1155 總供應量未顯示？

我希望能夠看到每個代幣的總供應量。我已經導入了擴展並遵循了關於 totalSupply 的 erc1155 文件，但是當在 Remix 上部署並呼叫總供應量時，即使在鑄造後它也顯示為 0？我無法弄清楚如何能夠顯示每個 id 已經鑄造了多少？這是我的合約程式碼，謝謝。

你tokenSupply的從來沒有增加。我對您的契約做了一些更改：

• 我在每個函式上添加了一個增量
• 由於您的程式碼被重複，我將其全部移到了一個private函式中
• 我減少了error消息的數量（花費很多）。這將優化程式碼的大小

盡量確保您的錯誤消息不超過 32 個字元（32 字節），否則它將儲存在 64 字節上。

function mintPoloy() public {
   require(_hasMinted(), "Already minted cheater!");
   tokenSupply[Poloy]++;
   _mint(msg.sender, Poloy, 1, "0x000");

}

function mintLeafy() public {
   require(_hasMinted(), "Already minted cheater!");
   tokenSupply[Leafy]++;
   _mint(msg.sender, Leafy, 1, "0x000");
   
}

function _hasMinted() private view returns (bool) {
   return
       ((balanceOf(msg.sender, Poloy) + balanceOf(msg.sender, Leafy)) > 0)
           ? false
           : true;
}
