CryptoZombies Contracts

This repository contains the Solidity smart contracts developed during the CryptoZombies course.

Course Summary

The CryptoZombies course is an interactive tutorial that teaches the basics of Solidity and smart contract development on the Ethereum blockchain.

Key Takeaways from Lessons:

Lesson 1: Getting Started with Solidity

Basic Solidity Syntax: Introduction to Solidity and its basic syntax. Smart Contract Structure: Understanding the structure of a smart contract. State Variables and Integers: Learning about state variables and integer types in Solidity. Functions: Writing basic functions and understanding their usage. Structs and Arrays: Using structs and arrays to store data.

Lesson 2: Zombies Factory

Creating Multiple Zombies: Implementing a factory pattern to create multiple zombies. Mappings and Addresses: Using mappings and addresses to keep track of zombie ownership. Events: Emitting events to notify off-chain applications about changes in the contract.

Lesson 3: Advanced Solidity Concepts

Inheritance: Using inheritance to extend functionality in smart contracts. Visibility Modifiers: Understanding public, private, internal, and external visibility modifiers. More on Functions: Exploring view functions, pure functions, and the concept of gas costs.

Lesson 4: Interacting with Other Contracts

Interfaces: Defining and using interfaces to interact with other contracts. Handling Multiple Contracts: Splitting code into multiple contracts for better organization. Random Number Generation: Implementing pseudo-random number generation in Solidity.

Lesson 5: ERC721 and Crypto Collectibles

ERC721 Standard: Implementation of non-fungible tokens (NFTs) and how they are used to create tradable assets like our zombies. Libraries: Usage of libraries in Solidity for reusable code. SafeMath Library: Ensuring safe arithmetic operations to prevent overflows and underflows. NatSpec: Writing comments in Solidity for better documentation and understanding.

Contracts

Here are the Solidity contracts developed during the course:

ZombieFactory.sol: The main contract for creating new zombies.

ZombieFeeding.sol: Handles zombie feeding logic and DNA combination.

ZombieHelper.sol: Provides additional functionalities like changing the zombie's name and level-up mechanism.

ZombieAttack.sol: Contains the battle mechanics between zombies.

ZombieOwnership.sol: Implements ERC721 standard functions for transferring zombie ownership.
