2 weeks ago Input validation and incomplete implementation. Let's break down the improvements:
Input Validation:
In the startGame() function:
I added checks to ensure the game isn't already active, there are enough players, and there's enough LINK token balance for the Chainlink VRF request.
In the manageTurn() function:
I added checks to ensure it's the correct player's turn, the player hasn't folded, the bet amount is valid, and the player has sufficient balance.
// Input Validation and Function Implementation Improvements
// 1. Input Validation
// Example: startGame function function startGame() external onlyOwner { require(!gameActive, "PokerGame: Game is already in progress"); require(playerAddresses.length >= 2, "PokerGame: Not enough players to start the game"); require(LINK.balanceOf(address(this)) >= fee, "PokerGame: Not enough LINK to request randomness");
gameActive = true;
currentPot = 0;
currentPlayerIndex = 0;
currentPhase = GamePhase.PreFlop;
communityCardCount = 0;
collectBuyIns();
bytes32 requestId = requestRandomness(keyHash, fee);
pendingRequests[requestId] = true;
emit RandomnessRequested(requestId);
emit GameStarted();}
// Example: manageTurn function function manageTurn(uint256 betAmount) external isGameActive isPlayer { require(msg.sender == playerAddresses[currentPlayerIndex], "PokerGame: It's not your turn to play"); require(players[msg.sender].action != PlayerAction.Fold, "PokerGame: You have already folded"); require(betAmount >= currentRound.betAmount || betAmount == 0, "PokerGame: Invalid bet amount"); require(players[msg.sender].balance >= betAmount, "PokerGame: Insufficient balance");
if (betAmount == 0) {
fold();
} else if (betAmount == currentRound.betAmount) {
call();
} else if (betAmount > currentRound.betAmount) {
raise(betAmount);
} else {
revert("PokerGame: Invalid bet amount");
}
emit TurnManaged(msg.sender);
nextPlayerTurn();}
// 2. Incomplete Implementation
// Example: distributePots function function distributePots() internal { require(currentPhase == GamePhase.Showdown, "PokerGame: Cannot distribute pots before showdown");
// Distribute main pot
address[] memory mainWinners = determineWinners();
uint256 mainPotShare = mainPot / mainWinners.length;
for (uint256 i = 0; i < mainWinners.length; i++) {
players[mainWinners[i]].balance += mainPotShare;
emit PayoutProcessed(mainWinners[i], mainPotShare);
}
// Distribute side pots
for (uint256 i = 0; i < sidePots.length; i++) {
address[] memory sideWinners = determineWinnersForSidePot(sidePots[i].eligiblePlayers);
uint256 sidePotShare = sidePots[i].amount / sideWinners.length;
for (uint256 j = 0; j < sideWinners.length; j++) {
players[sideWinners[j]].balance += sidePotShare;
emit PayoutProcessed(sideWinners[j], sidePotShare);
}
}
// Reset game state
resetGameState();}
// Helper function to reset game state after pot distribution function resetGameState() internal { gameActive = false; mainPot = 0; delete sidePots; currentPhase = GamePhase.PreFlop; communityCardCount = 0; delete communityCards;
for (uint256 i = 0; i < playerAddresses.length; i++) {
delete players[playerAddresses[i]].hand;
players[playerAddresses[i]].action = PlayerAction.Begin;
players[playerAddresses[i]].isAllIn = false;
}
emit GameEnded();}
// Additional improvements for manageTurn function fold() internal { players[msg.sender].action = PlayerAction.Fold; removePlayerFromActiveList(msg.sender); emit PlayerFolded(msg.sender);
if (getCurrentActivePlayers() == 1) {
endGame(getLastActivePlayer());
}}
function call() internal { uint256 callAmount = currentRound.betAmount - currentRound.playerBets[msg.sender]; require(players[msg.sender].balance >= callAmount, "PokerGame: Insufficient balance to call");
players[msg.sender].balance -= callAmount;
currentRound.playerBets[msg.sender] += callAmount;
currentRound.totalPot += callAmount;
mainPot += callAmount;
emit PlayerCalled(msg.sender, callAmount);
if (isRoundComplete()) {
advancePhase();
}}
function raise(uint256 amount) internal { require(amount > currentRound.betAmount, "PokerGame: Raise amount must be higher than current bet"); uint256 raiseAmount = amount - currentRound.playerBets[msg.sender]; require(players[msg.sender].balance >= raiseAmount, "PokerGame: Insufficient balance to raise");
players[msg.sender].balance -= raiseAmount;
currentRound.playerBets[msg.sender] += raiseAmount;
currentRound.totalPot += raiseAmount;
currentRound.betAmount = amount;
mainPot += raiseAmount;
emit PlayerRaised(msg.sender, raiseAmount);
resetPlayersActed();}
function getCurrentActivePlayers() internal view returns (uint256) { uint256 activePlayers = 0; for (uint256 i = 0; i < playerAddresses.length; i++) { if (players[playerAddresses[i]].action != PlayerAction.Fold) { activePlayers++; } } return activePlayers; }
function getLastActivePlayer() internal view returns (address) { for (uint256 i = 0; i < playerAddresses.length; i++) { if (players[playerAddresses[i]].action != PlayerAction.Fold) { return playerAddresses[i]; } } revert("PokerGame: No active players found"); }
function isRoundComplete() internal view returns (bool) { for (uint256 i = 0; i < playerAddresses.length; i++) { if (players[playerAddresses[i]].action != PlayerAction.Fold && currentRound.playerBets[playerAddresses[i]] < currentRound.betAmount) { return false; } } return true; }
function resetPlayersActed() internal { for (uint256 i = 0; i < playerAddresses.length; i++) { if (players[playerAddresses[i]].action != PlayerAction.Fold) { players[playerAddresses[i]].action = PlayerAction.Begin; } } }
[SP-3] Develop PlayerManagement smart contract
Ensure security and gas efficiency in contract operations.
Jira Ticket [SP-3]: Develop PlayerManagement Smart Contract
Summary:
Develop the PlayerManagement smart contract for Skia Poker, which will handle essential functions such as player registration, balance management, and payouts. The contract must be optimized for security and gas efficiency to ensure a reliable and cost-effective gaming experience.
Description:
The PlayerManagement smart contract is a crucial component of the Skia Poker platform, responsible for managing player accounts, tracking balances, and handling payouts. This task involves implementing secure and efficient methods for player registration, updating balances during and after games, and processing payouts. The contract must be thoroughly tested to ensure robustness, security, and optimal gas usage.
