A simple C# extension to easily create WaitForSeconds coroutines

MonoExtensions.cs

using System.Collections;
using UnityEngine;
using UnityEngine.Events;

public static class MonoExtensions 
{
    public static Coroutine Wait(this MonoBehaviour mono, float delay, UnityAction action)
    {
        return mono.StartCoroutine(ExecuteAction(delay, action));
    }

    private static IEnumerator ExecuteAction(float delay, UnityAction action)
    {
        yield return new WaitForSecondsRealtime(delay);
        action?.Invoke();
        yield break;
    }
}

//Example usage.
public class SampleClass : MonoBehaviour
{
    //Delay duration in seconds
    private float animationDelay = 2.0f;
    public Animator animator;

    private void Awake()
    {
        animator.SetBool("isActive", false);

        //This line will call the animate function 2 seconds later.
        this.Wait(animationDelay, Animate);

        //Or you can keep the coroutine if you want to kill later in your code.
        Coroutine c = this.Wait(animationDelay, Animate);

        //Kill the coroutine.
        StopCoroutine(c);
    }

    private void Animate()
    {
        animator.SetBool("isActive", true);
        Debug.Log("Animation is now active");
    }
}

Thanks 🚀🚀
