Call method on all derived classes from base

Questions & Answers
1

What I need to acomplish, is hook into the BaseBehaviour, whenever OnGameSlowdown is called on the BaseBehaviour, it needs to trigger said method in all derived classes.

In this example. OnGameSlowdown gets called whenever the game slows down, I want to hook this method from other components to do something specific to each component that is listening.

public class BaseBehaviour : MonoBehaviour
{
    protected virtual void OnGameSlowdown()
    {
        Debug.Log("Base OnGameSlowdown");
    }

    protected virtual void OnGameResume()
    {
    }

    public IEnumerator Slowdown(float slowdownTime, float slowdownDuration)
    {
        Time.timeScale = slowdownTime;
        OnGameSlowdown();

        yield return new WaitForSeconds(slowdownDuration * slowdownTime);

        Time.timeScale = 1f;
        OnGameResume();
    }
}

PlayerController

public class PlayerController : BaseBehaviour
{
    protected override void OnGameSlowdown()
    {
        Debug.Log("PlayerController OnGameSlowdown");

    }
}

Solution to my issue was to instead use SendMessage, example:

    public IEnumerator Slowdown(float slowdownTime, float slowdownDuration)
    {
        Time.timeScale = slowdownTime;
        SendMessage(nameof(OnGameSlowdown));

        yield return new WaitForSeconds(slowdownDuration * slowdownTime);

        Time.timeScale = 1f;
        SendMessage(nameof(OnGameResume));
    }
