Pros of Unity-Programming-Patterns

• More comprehensive coverage of design patterns, including structural and behavioral patterns
• Includes practical examples and use cases for each pattern in Unity
• Regularly updated with new patterns and improvements

Cons of Unity-Programming-Patterns

• Less focus on performance optimization compared to unity-design-patterns
• May be overwhelming for beginners due to the large number of patterns covered

Code Comparison

unity-design-patterns:

public class Singleton<T> : MonoBehaviour where T : MonoBehaviour

    public static T Instance
    {
        get

                if (_instance == null)
                {
                    GameObject obj = new GameObject();
                    _instance = obj.AddComponent<T>();
                }
            }
            return _instance;
        }
    }
}

Unity-Programming-Patterns:

public class Singleton<T> : MonoBehaviour where T : Component
{
    private static T _instance;
    public static T Instance
    {
        get
        {
            if (_instance == null)
            {
                _instance = FindObjectOfType<T>();
                if (_instance == null)
                {
                    GameObject obj = new GameObject();
                    obj.name = typeof(T).Name;
                    _instance = obj.AddComponent<T>();
                }
            }
            return _instance;
        }
    }
}

Both repositories implement the Singleton pattern similarly, with Unity-Programming-Patterns adding a name to the created GameObject for better organization.

Pros of Unity-Design-Pattern

• More comprehensive coverage of design patterns, including additional categories like Architectural, Concurrency, and Game Programming patterns
• Includes detailed explanations and UML diagrams for each pattern, enhancing understanding
• Provides both C# and TypeScript implementations for broader applicability

Cons of Unity-Design-Pattern

• Less focused on Unity-specific implementations compared to unity-design-patterns
• May be overwhelming for beginners due to the extensive coverage of patterns

Code Comparison

Unity-Design-Pattern (Singleton pattern):

public class Singleton<T> : MonoBehaviour where T : Component
{
    private static T _instance;
    public static T Instance {
        get {
            if (_instance == null) {
                _instance = FindObjectOfType<T>();
                if (_instance == null) {
                    GameObject obj = new GameObject();
                    _instance = obj.AddComponent<T>();
                }
            }
            return _instance;
        }
    }
}

unity-design-patterns (Singleton pattern):

public class Singleton<T> : MonoBehaviour where T : MonoBehaviour
{
    private static T _instance;
    public static T Instance {
        get {
            if (_instance == null) {
                _instance = (T)FindObjectOfType(typeof(T));
                if (_instance == null) {
                    var singletonObject = new GameObject();
                    _instance = singletonObject.AddComponent<T>();
                    singletonObject.name = typeof(T).ToString() + " (Singleton)";
                }
            }
            return _instance;
        }
    }
}

Pros of EntityComponentSystemSamples

• Official Unity repository, ensuring up-to-date and accurate implementation of ECS
• Comprehensive examples covering various aspects of the Entity Component System
• Demonstrates performance optimizations and best practices for ECS in Unity

Cons of EntityComponentSystemSamples

• Focused solely on ECS, lacking coverage of other design patterns
• May be overwhelming for beginners due to its complexity and advanced concepts
• Requires Unity 2019.3 or later, limiting compatibility with older projects

Code Comparison

EntityComponentSystemSamples:

public class MovementSystem : SystemBase
{
    protected override void OnUpdate()

        float deltaTime = Time.DeltaTime;
        Entities.ForEach((ref Translation position, in Velocity velocity) =>
        {
            position.Value += velocity.Value * deltaTime;
        }).ScheduleParallel();
    }
