What is the Composite Pattern in Unity?

Can you explain the Composite Pattern in Unity?

Sure! The Composite Pattern is a structural design pattern that lets you compose objects into tree structures to represent part-whole hierarchies. In Unity, it's often used to manage groups of game objects.

How would I implement this pattern in a Unity project?

You can start by creating a base class or interface for your components, then create leaf classes for individual objects and composite classes for groups. This way, you can treat both single objects and groups uniformly.

Can you give me a code example?

Absolutely! Here's a simple example:

public interface IComponent {
    void Operation();
}

public class Leaf : IComponent {
    public void Operation() {
        Debug.Log("Leaf operation");
    }
}

public class Composite : IComponent {
    private List<IComponent> _children = new List<IComponent>();

    public void Add(IComponent component) {
        _children.Add(component);
    }

    public void Operation() {
        foreach (var child in _children) {
            child.Operation();
        }
    }
}

This code defines a simple composite structure.

What are some use cases for the Composite Pattern in games?

Common use cases include managing UI elements, creating complex game objects like trees or buildings, and organizing game entities in a scene.
