- Defined error constants for various error scenarios: - ERR-NOT-AUTHORIZED: Unauthorized access attempt. - ERR-INVALID-GAME-ASSET: Invalid game asset. - ERR-INSUFFICIENT-FUNDS: Insufficient funds for operation. - ERR-TRANSFER-FAILED: Asset transfer failed. - ERR-LEADERBOARD-FULL: Leaderboard is full. - ERR-ALREADY-REGISTERED: Player already registered. - ERR-INVALID-REWARD: Invalid reward distribution. These constants will be used throughout the contract to handle and signal different error conditions.
- Defined a non-fungible token (NFT) called `game-asset` with `uint` as the token identifier. - Created a `game-asset-metadata` map to store metadata for each game asset, including: - `name`: Name of the game asset (up to 50 ASCII characters). - `description`: Description of the game asset (up to 200 ASCII characters). - `rarity`: Rarity level of the game asset (up to 20 ASCII characters). - `power-level`: Power level of the game asset (unsigned integer). These additions enable the creation and management of game assets as NFTs with associated metadata.
- Defined `game-fee` to store the entry fee in STX. - Defined `max-leaderboard-entries` to store the maximum number of leaderboard entries. - Defined `total-prize-pool` to store the total prize pool amount. These variables will be used to manage the game's configuration and state.
- Defined a `leaderboard` map to store player statistics, including: - `score`: Player's score. - `games-played`: Number of games played by the player. - `total-rewards`: Total rewards earned by the player. This structure will be used to maintain and track player performance and rewards.
- Defined `game-admin-whitelist` map to store game administrators. - Added `is-game-admin` private function to check if a sender is a game admin. - Added `add-game-admin` public function to allow existing admins to add new game administrators. These additions enable the management and authorization of game administrators.
- Defined `mint-game-asset` public function to mint a new game asset NFT. - Parameters include: - `name`: Name of the game asset. - `description`: Description of the game asset. - `rarity`: Rarity level of the game asset. - `power-level`: Power level of the game asset. - Checks if the sender is a game admin. - Mints the NFT and stores its metadata. - Increments the total number of game assets. This function allows game administrators to create new game assets as NFTs.
- Defined `transfer-game-asset` public function to transfer a game asset NFT. - Parameters include: - `token-id`: Identifier of the game asset to be transferred. - `recipient`: Principal of the recipient. - Checks if the sender is the owner of the game asset. - Transfers the NFT to the recipient. This function allows the transfer of game assets between players.
- Defined `register-player` public function to register a player for the game. - Checks if the player has sufficient funds to pay the registration fee. - Ensures the player is not already registered. - Transfers the registration fee to the contract. - Registers the player in the leaderboard with initial values for score, games played, and total rewards. This function allows players to register for the game by paying a fee.
- Defined `update-player-score` public function to update a player's score and game statistics. - Parameters include: - `player`: Principal of the player. - `new-score`: New score to be updated. - Checks if the sender is a game admin. - Retrieves the current statistics of the player. - Updates the player's score and increments the number of games played. - Stores the updated statistics in the leaderboard. This function allows game administrators to update player scores and game statistics.
- Defined `distribute-bitcoin-rewards` public function to distribute rewards to top players. - Checks if the sender is a game admin. - Retrieves the list of top players. - Placeholder logic for Bitcoin reward distribution, which would interact with a Bitcoin bridge in a real implementation. - Uses a fold function to distribute rewards to each top player. This function allows game administrators to distribute Bitcoin rewards to top players.
- Defined `distribute-reward` private function to distribute rewards to a player. - Parameters include: - `player`: Principal of the player. - `previous-result`: Result from the previous fold iteration. - Retrieves the player's statistics from the leaderboard. - Calculates the reward amount based on the player's score. - Updates the player's total rewards in the leaderboard. This function is used to distribute rewards to players during the reward distribution process.
- Defined `calculate-reward` private function to calculate rewards based on a player's score. - If the score is greater than 100, the reward is calculated as `score * 10`. - Otherwise, the reward is 0. - Defined `get-top-players` read-only function to retrieve the top players. - Retrieves the maximum number of leaderboard entries. - Currently returns a placeholder list with `tx-sender`. These functions support the reward distribution process by calculating rewards and identifying top players.
- Defined `initialize-game` public function to set the game configuration.
- Parameters include:
- `entry-fee`: Entry fee for the game.
- `max-entries`: Maximum number of leaderboard entries.
- Checks if the sender is a game admin.
- Sets the game fee and maximum leaderboard entries.
- Defined `total-game-assets` global variable to track the total number of game assets.
- Set the contract deployer as the first game admin.
These additions allow the initialization of game settings and track the total game assets.
…ecks - Added input validation for `initialize-game` function: - Ensured `entry-fee` is between 1 and 1000. - Ensured `max-entries` is between 1 and 500. - Enhanced security checks for game administration and player interactions: - Validated inputs for `mint-game-asset` and `transfer-game-asset` functions. - Ensured only authorized game admins can perform administrative actions. These enhancements improve the robustness and security of the smart contract.
…bution - Enhanced `distribute-reward` function to validate player registration and score: - Ensured the player is registered in the leaderboard. - Only distributed rewards to players with a score greater than 0. - Updated reward calculation logic to handle valid players only. These validations ensure that rewards are distributed only to eligible and registered players.
- Provided an overview of the smart contract's purpose and functionality. - Detailed the key features, including game asset management, player management, and reward distribution. - Described the main contract components, including key data structures and error handling. - Listed the main functions for administration, asset management, and player interactions. - Highlighted security measures implemented in the contract. - Specified requirements and deployment considerations. - Included usage examples for common operations. - Suggested potential improvements for future development. This README serves as a detailed guide for understanding and using the Powered Gaming Ecosystem Smart Contract.
…ogic - Added `is-valid-string` private function to validate input strings. - Improved `is-valid-principal` and `is-safe-principal` functions for enhanced principal validation. - Updated `add-game-admin` function to include enhanced validation for new administrators. - Enhanced reward distribution logic to validate player registration and score before distributing rewards. - Ensured only valid and registered players with non-zero scores receive rewards. These enhancements improve the robustness and security of player validation and reward distribution.
