What smart contracts does Chaos racer use?
Driving Innovation with Smart Contracts in Chaos Racer
Chaos Racer utilizes various types of smart contracts for different aspects of the game. Here is a more detailed description of each type of smart contract that can be used in Chaos Racer:
- NFT Asset Smart Contracts: These smart contracts are responsible for creating, managing, and trading NFT assets within the game. They define the unique properties and characteristics of each asset, such as vehicles, equipment items, and other in-game resources. NFT Asset Smart Contracts also ensure the security and transparency of asset ownership, as well as facilitate the transfer of assets between players.

}
function simpleToken() public {
totalSupply_ = initialSupply;
balances[msg.sender] = initialSupply;
emit Transfer(0x0, msg.sender, initialSupply);
}
}
- Economic System Smart Contracts: These smart contracts define the economic model of Chaos Racer. They may include contracts for distributing rewards to players, determining pricing in the in-game asset marketplace, executing contract conditions, and other economic operations. Economic System Smart Contracts ensure the reliability and fairness of resource allocation and rewards distribution.pragma solidity ^0.8.0;contract ChaosRacerEconomicSystem {mapping(address => uint256) public playerBalances;mapping(address => uint256) public playerRewards;event RewardDistribution(address indexed player, uint256 amount);function distributeRewards(address[] memory players, uint256[] memory amounts) external {require(players.length == amounts.length, "Invalid input");for (uint256 i = 0; i < players.length; i++) {address player = players[i];uint256 amount = amounts[i];playerRewards[player] += amount;emit RewardDistribution(player, amount);}}function withdrawRewards() external {uint256 reward = playerRewards[msg.sender];require(reward > 0, "No rewards to withdraw");playerRewards[msg.sender] = 0;playerBalances[msg.sender] += reward;}function buyInGameAsset(uint256 price) external {require(playerBalances[msg.sender] >= price, "Insufficient balance");// Execute the contract conditions and asset purchase logicplayerBalances[msg.sender] -= price;}}
- Gameplay Mechanics Smart Contracts: These smart contracts govern the rules and mechanics of the Chaos Racer game. They may verify player achievements, calculate race results, manage artificial intelligence, and other gameplay mechanics. Gameplay Mechanics Smart Contracts ensure consistency and transparency in the game process.pragma solidity ^0.8.0;contract ChaosRacerGameplayMechanics {mapping(address => uint256) public playerAchievements;mapping(address => bool) public raceResults;mapping(address => uint256) public playerScores;address[] public players;event AchievementUnlocked(address indexed player, uint256 achievement);event RaceResult(address indexed player, bool result);event ScoreUpdated(address indexed player, uint256 score);function unlockAchievement(uint256 achievement) external {playerAchievements[msg.sender] = achievement;emit AchievementUnlocked(msg.sender, achievement);}function submitRaceResult(bool result) external {raceResults[msg.sender] = result;emit RaceResult(msg.sender, result);}function updateScore(address player, uint256 score) external {require(raceResults[player], "Player has not submitted the race result");playerScores[player] = score;emit ScoreUpdated(player, score);}function addPlayer(address player) external {players.push(player);}function getPlayerCount() external view returns (uint256) {return players.length;}}
- Community Governance Smart Contracts: These smart contracts are responsible for managing the Chaos Racer community. They may include voting for game changes, managing finances, and making decisions related to game content development. Community Governance Smart Contracts enable players to actively participate in shaping the game and making decisions that impact the game's ecosystem.pragma solidity ^0.8.0;contract ChaosRacerCommunityGovernance {struct Proposal {uint256 id;string description;uint256 voteCount;mapping(address => bool) votes;bool executed;}Proposal[] public proposals;mapping(address => bool) public communityMembers;uint256 public totalVotes;event ProposalCreated(uint256 indexed id, string description);event ProposalVoted(uint256 indexed id, address indexed voter);event ProposalExecuted(uint256 indexed id);modifier onlyCommunityMember() {require(communityMembers[msg.sender], "Only community members can call this function");_;}function createProposal(string memory description) external onlyCommunityMember {uint256 proposalId = proposals.length;proposals.push(Proposal(proposalId, description, 0, false));emit ProposalCreated(proposalId, description);}function vote(uint256 proposalId) external onlyCommunityMember {require(!proposals[proposalId].votes[msg.sender], "Already voted for this proposal");proposals[proposalId].votes[msg.sender] = true;proposals[proposalId].voteCount++;totalVotes++;emit ProposalVoted(proposalId, msg.sender);}function executeProposal(uint256 proposalId) external onlyCommunityMember {require(proposals[proposalId].voteCount > totalVotes / 2, "Not enough votes for the proposal");require(!proposals[proposalId].executed, "Proposal already executed");// Execute the proposal logic and make the necessary changesproposals[proposalId].executed = true;emit ProposalExecuted(proposalId);}function addCommunityMember(address member) external onlyCommunityMember {communityMembers[member] = true;}function removeCommunityMember(address member) external onlyCommunityMember {delete communityMembers[member];}}
Each of these types of smart contracts is crucial for the functioning and development of Chaos Racer. They interact with each other to ensure reliability, security, and transparency of the gameplay, and provide opportunities for player participation and interaction within the game.
