# Collision Detection and Events

The `Character` class includes numerous events that allow you to manage different character interactions. For instance, there is `OnCollided`, which is triggered when the character makes contact with a collider while executing a `Move`, `OnFoundGround`, which is triggered when a character detects any ground surface (whether **walkable** or **not-walkable**), among others.

When extending a `Character` class, it is advisable to override its corresponding event trigger method. For example, override the `OnCollided` method to handle a collision:

```csharp
public class PlayerCharacter : Character
{
    protected override void OnCollided(ref CollisionResult collisionResult)
    {
        // Call base method implementation
        
        base.OnCollided(ref collisionResult);
        
        // Add your code here...
        
        Debug.Log($"Collided with {collisionResult.collider.name}");
    }
}
```

On the other hand, when extending a `Character` through composition, it's advisable to listen to its exposed events. For example, subscribe to its `Collided` event to handle a collision:

```csharp
public class PlayerController : MonoBehaviour
{
    // The controlled Character

    private Character _character;

    protected void OnCollided(ref CollisionResult collisionResult)
    {
        Debug.Log($"Collided with {collisionResult.collider.name}");
    }

    private void OnEnable()
    {
        // Subscribe to Character events
        
        _character.Collided += OnCollided;
    }

    private void OnDisable()
    {
        // Un-subscribe from Character events
        
        _character.Collided -= OnCollided;
    }
}
```

The procedure is the same for its other events.
