How to check if a list of class contains a class rather than an instance of a class?

[valmarus]

Using c#. If I have a class FireClass that inherits from SpellClass. How do I check if a List of SpellClass contains ANY instance of FireClass rather than a specific instance of FireClass as with “GameManager.Instance.AbilityDB.Contains(passedSpellClass)” ?

You can use a LINQ method “Any” and a “is” operator for the condition.

Here are a couple of references:

• Enumerable.Any Method (System.Linq) | Microsoft Learn
• The `is` operator - Match an expression against a type or constant pattern | Microsoft Learn

Here’s an example:

using System.Linq;
using System.Collections.Generic;
using UnityEngine;

public class TestScript : MonoBehaviour
{
    public List<Spell> spells = new List<Spell>();

    private void Start()
    {
        if (HasSpellOfType<Fire>())
        {
            Debug.Log("Fire!!!");
        }
    }

    public bool HasSpellOfType<T>() where T : Spell
    {
        return spells.Any(x => x is T);
    }
}

public class Fire : Spell { /* ... */}
public class Spell { /* ... */}
