If you’re looking to dive into the world of non-fungible tokens (NFTs) and create your very own ERC-721 tokens, you’re in the right place! This simple game ERC-721 token template makes it easy to set up your unique tokens on the Ethereum blockchain.

What is ERC-721?

ERC-721 is a free, open standard that helps developers create non-fungible tokens on the Ethereum blockchain. Unlike regular tokens (which are interchangeable), each ERC-721 token is unique. A popular example is Crypto Kitties, where every cat represents a distinct ERC-721 token.

Setting Up Your ERC-721 Token

The setup process is straightforward! You just need to click on the following links to access the coding platform:

• Remix IDE Link
• GitHub Gist Link

If you encounter any issues, you can manually add each file, and it won’t take more than a minute!

Explaining the Code Analogy

To better understand the code for creating your ERC-721 tokens, let’s use an analogy of a magic book factory:

Imagine a factory that creates unique magic books. Each book has its own cover design (the name), a secret power level (level), and a rarity score (rarity level). Here’s how it works:

• At lines **5-9**, we define the blueprint for a magic book, including its properties, just like outlining the characteristics of each book.
• At line **11**, we set up a storage room where all completed books are stored, similar to a library.
• Lines **14-16** clarify that the factory owner holds the keys to the workshop (only the owner can create books).
• Line **18** introduces a function called **createItem**, where the owner can give a name and choose an address for the book’s magical delivery.
• In line **19**, we ensure that only the factory owner can indeed create these magical books.
• Line **20** establishes each book with a unique identification number based on the total number of books made so far.
• Lines **21-22** showcase the process of conjuring a book (creating and storing it in the library), followed by sending it to a chosen address (minting the token).

The ERC-721 Token Code

Here’s a simplified version of the Solidity code you will use:

pragma solidity ^0.4.24;

contract Item is ERC721 {
    struct Item {
        string name; // Name of the Item
        uint level; // Item Level
        uint rarityLevel; // 1 = normal, 2 = rare, 3 = epic, 4 = legendary
    }
    
    Item[] public items; // First Item has Index 0
    address public owner;
    
    function Item() public {
        owner = msg.sender; // The Sender is the Owner; Ethereum Address of the Owner
    }
    
    function createItem(string _name, address _to) public {
        require(owner == msg.sender); // Only the Owner can create Items
        uint id = items.length; // Item ID = Length of the Array Items
        items.push(Item(_name, 5, 1)); // Item (Sword, 5, 1)
        _mint(_to, id); // Assigns the Token to the Ethereum Address that is specified
    }
}

Troubleshooting Tips

If you face any challenges during the setup process, here are some troubleshooting ideas:

• Ensure you’re using the correct version of the Remix IDE linked above.
• Check that all necessary files are correctly added to your workspace.
• Double-check the syntax in your Solidity code for any errors.
• If you’re stuck, consider reaching out for help from the developer community or online forums.
