ON_CHAIN_MMORPG is a fully on-chain multiplayer online role-playing game (MMORPG) built on the Aptos blockchain. The contract is designed with modularity, interactivity, and a real economic system at its core. It implements player registration, equipment crafting, battle matchmaking, and an in-game currency system — all executed and stored on-chain to ensure transparency and immutability.

• ✅ Fully On-Chain Execution: Player states, equipment, and battle results are all stored on-chain, ensuring fairness and transparency.
• ⚔️ Weapon Crafting System: Weapons are minted with random attributes (attack and speed) using on-chain randomness, making each one unique.
• 🎮 Battle Matchmaking Mechanism: Fair combat logic with random critical hits ensures competitive and unpredictable outcomes.
• 🪙 GameCoin Economic System: A custom in-game token supports minting, burning, and transfers to simulate a closed-loop game economy.
• 🧾 Event-Driven Logging: Events for weapon minting and battles are emitted on-chain, enabling frontend integrations and auditability.
• 🔐 Modular and Secure Resource Design: Uses Aptos resource safety and object systems to protect user assets and enable extensibility.

• Initialize a player collection using create_player_collection.
• Mint a weapon with randomized attack and speed using create_weapon_entry.
• Each mint emits a MintWeaponEvent for frontend listening and tracking.

• Use match_challenge to initiate a battle challenge.
• The system determines the winner based on critical hit logic and attack speed comparison.
• The winner gains the staked GameCoin, while the loser loses part of their stake.

• Create the in-game token using create_coin.
• Supports minting, burning, and peer-to-peer transfers.
• All battle activities are driven by GameCoin, simulating a real economic model.

• aptos_framework::event – On-chain event emission system
• aptos_framework::randomness – Source of randomness for weapon stats and critical hits
• aptos_token_objects::token and collection – Implementation of NFT systems
• rpg_game::game_coin – Custom module for GameCoin token management

• 🌐 Native On-Chain Game Design
  All core logic runs entirely on-chain, ensuring trustworthy and tamper-proof game rules.

• 🛠️ Modular and Extensible
  Designed for easy future expansion — including equipment systems, quest modules, and in-game markets.

• 💸 Real Economic Model
  Built on Token and NFT standards to support asset circulation and in-game value exchange.

• 📈 Scalability & Growth Potential
  Early supporters can participate in governance and share economic returns through incentive mechanisms.
