Passing arguments with EventHandlers

Is there a way to pass custom arguments with EventHandlers?

IE:

Code (CSharp):

1. public event EventHandler OnDamagedEvent;
2.  
3. public void SomeTakeDamageMethodEtc()
4. {
5.     ////Calculate damage etc etc
6.     OnDamagedEvent?.Invoke(this, EventArgs.Empty, damageTaken);
7. }

I've been struggling trying to figure this out the simplest way possible.

 

You'll need to create a Unity Event class...

Examples
UnityEvent<T0>
UnityEvent<T0,T1>
UnityEvent<T0,T1,T2>
UnityEvent<T0,T1,T2,T3>

Hope this helps.

 

To expand on what @Vectorbox said, if you create a class from a unity event, you can also populate a unity event in the inspector.

Code (CSharp):

1.     using UnityEngine.Events;
2.  
3.     //....
4.  
5.     [Serializable]
6.     public class IntEvent : UnityEvent<int> { }
7.  
8.     public IntEvent OnDamagedEvent;
9.  
10.     public int DamageTaken;
11.  
12.     public void SomeTakeDamageMethod()
13.     {
14.         OnDamagedEvent.Invoke(DamageTaken);
15.     }
