Event Declaration

https://stackoverflow.com/.../how-to-use-c-sharp-events...

Class containing events:

public class EventContainer : MonoBehaviour
{
    public event Action<string> OnShow;
    public event Action<string,float> OnHide;
    public event Action<float> OnClose;

    void Show()
    {
        Debug.Log("Time to fire OnShow event");
        if(OnShow != null)
        {
            OnShow("This string will be received by listener as arg");
        }
    }

    void Hide()
    {
        Debug.Log("Time to fire OnHide event");
        if(OnHide != null)
        {
            OnHide ("This string will be received by listener as arg", Time.time);
        }
    }

    void Close()
    {
        Debug.Log("Time to fire OnClose event");
        if(OnClose!= null)
        {
            OnClose(Time.time); // passing float value.
        }
    }
}
Class which handles events of EventContainer class:

public class Listener : MonoBehaviour
{
    public EventContainer containor; // may assign from inspector

    void Awake()
    {
        containor.OnShow += Containor_OnShow;
        containor.OnHide += Containor_OnHide;
        containor.OnClose += Containor_OnClose;
    }

    void Containor_OnShow (string obj)
    {
        Debug.Log("Args from Show : " + obj);
    }

    void Containor_OnHide (string arg1, float arg2)
    {
        Debug.Log("Args from Hide : " + arg1);
        Debug.Log("Container's Hide called at " + arg2);
    }

    void Containor_OnClose (float obj)
    {
        Debug.Log("Container Closed called at : " + obj);
    }

}
