Case study – putting it all together

Here, we’ll bring together all the elements we’ve discussed so far: higher-order functions, delegates, actions, funcs, predicates, and LINQ methods. We’ll provide a comprehensive, real-world example and analyze the code, step by step.

Imagine we are developing a mobile tower defense game. This game involves managing towers, handling enemy waves, and upgrading tower capabilities.

Here’s an outline of the classes we’ll use:

public class Tower
{
    public string Type { get; set; }
    public int Damage { get; set; }
    public bool IsUpgraded { get; set; }
}
public class Game
{
    private List<Tower> _towers { get; set; }
    public IEnumerable<Tower> FilterTowers(Func<Tower, bool> predicate) { /* … */ }
    public event Action<Tower> TowerUpgraded...
