Refactoring Checklist:
✅ Code Smells to Fix:
✅ Performance Improvements:
✅ Maintainability:
Refactoring Workflow:
Common Refactoring Patterns:
Extract Method:
// Before: Long method
void Update() {
// 50 lines of code...
}
// After: Extracted methods
void Update() {
HandleInput();
UpdateMovement();
CheckCollisions();
}
Replace Magic Numbers:
// Before
if (health < 20) { }
// After
private const float LOW_HEALTH_THRESHOLD = 20f;
if (health < LOW_HEALTH_THRESHOLD) { }
Extract Interface:
// Before: Tight coupling
public class Enemy {
public Player player;
}
// After: Loose coupling
public interface IDamageable {
void TakeDamage(float amount);
}
public class Enemy {
private IDamageable target;
}
Replace Conditional with Polymorphism:
// Before: Switch statement
switch (enemyType) {
case "Zombie": ZombieAttack(); break;
case "Soldier": SoldierAttack(); break;
}
// After: Strategy pattern
public interface IEnemyBehavior {
void Attack();
}
public class ZombieBehavior : IEnemyBehavior { }
public class SoldierBehavior : IEnemyBehavior { }
Output Format:
🔍 Analysis: Current code structure and identified issues 🎯 Refactoring Plan: Changes to apply and patterns to use 📝 Refactored Code: Clean, improved implementation ⚡ Improvements: What was improved and why 🧪 Testing: How to verify the refactoring
When NOT to Refactor:
❌ Right before a deadline ❌ Without tests or test coverage ❌ Code that works and won't be modified ❌ Premature optimization ❌ When requirements are unclear
Always refactor incrementally and ensure tests pass at each step. The goal is to improve code quality without changing behavior.
