Overview

The DraftMultiMinter is a robust ERC-1155 contract facilitating the creation of various token types that are essential for diverse game mechanics and economies. This contract is specifically designed to enable:

• Fungible Tokens (FTs): Represent in-game resources like currency and experience boosters.
• Non-Fungible Tokens (NFTs): Serve as unique player cards, stadium elements, or collectible game assets.

Key Features

• Distinct Token Types: Effortlessly categorize tokens into their specific roles, simplifying the creation of multifaceted game mechanics.
• Efficient Minting: Mints both fungible and non-fungible tokens in a streamlined manner.
• NFT Supply Management: Tracks the supply of NFTs with built-in safeguards to prevent over-minting and maintain scarcity.
• Metadata Handling: Provides a standard mechanism for defining individual token metadata that's compatible with external marketplaces and visualization tools.
• Ownable: Includes ownership controls to regulate contract administration.
• Pausable: Offers the ability to pause token transfers as needed for updates or emergency scenarios.

Code Highlights

1. ERC-1155 Standard: Leverages the ERC-1155 standard to establish core functionalities for minting multiple token types with associated amounts and metadata in a single contract.

2. Token Type Enumeration: The TokenType enum allows for clear identification of supported token categories:

   • IN_GAME_CURRENCY
   • EXPERIENCE_BOOST
   • PLAYER_CARD
   • STADIUM_VILLAGE_BUILDING

3. Minting Functions: The contract implements separate functions for efficient minting:

   • mintFT(): Mint fungible tokens with defined types and quantities.
   • mintNFT(): Create NFTs, tracking supply to enforce limits.

4. Metadata Management:

   • setURI(): Provides an administrative function to update the base URI for metadata.
   • uri(): Overrides the standard uri() function to fetch dynamic metadata for each token based on its ID and the base URI.

Getting Started

1. Deployment:

   • Deploy the DraftMultiMinter.sol contract to your desired blockchain environment.

2. Configuration:

   • Replace the placeholder in the constructor ("https://turquoise-rear-loon-357.mypinata.cloud/ipfs/QmahUaDqT8b4dMcibzZJzVy2edV2rTU6sKDUqcNavJEMJ7/{id}.json") with your actual base metadata URI if the IPFS-stored structure differs.

3. Minting:

   • Use the mintFT() and mintNFT() functions to create the necessary tokens for your game.

Using the Contract

To ensure efficient usage, make note of the following:

• getTokenId() Function: Utilize this function to obtain the token ID associated with a particular TokenType which is vital for minting calls.
• isFungibleToken() and isNonFungibleToken(): Employ these helper functions to easily determine the type of a given token ID.
• Access Controls: Be cognizant that sensitive calls, such as minting, are reserved for the contract owner.
