C#, Unity: How Can I use different class objects for the same constructor?

Question

I'm writing a simple game in unity and would like to construct a combat function

public CombatVsMonster (Character character, Monster monster)

this is what I have (takes a character and monster and executes a combat)

How can I make the same code work with (merging those two, so the second constructor can be either Monster or Character class)

public CombatVsMonster (Character character, Character character)

in other words: Can I have a constructor that would be able to take in different class objects? If yes: how?

There are many possible approaches to what you're describing. When you make a complete attempt, is there a specific error or problem that you encounter? — David

There are many ways to approach this, but a common thread shared by most games which include any sort of "Monster" is that the player, monsters, etc all have some things in common, such as HitPoints.

If that's true of yours as well, then using inheritance is probably the easiest way to accomplish what you want. "Character" should have things common to all Characters, be them NPCs or the player. From there, if Player and Monster both inherit from Character, then you can pass them both to any function that accepts Character as a parameter. This should save you a lot of code, since it would allow one function to handle interactions between Characters. They will both have all of the features of a Character, but will also have their own attributes and properties.

This makes it clear to me: I'll make a new Class and derive both Character and Monster from it. Your solution was clear and through.Thank you very much.

You need to create an interface that will be inherited to its childs.

class Character : MonoBehavior, IActor
{
     public float Hp {get;set;}

     private float _damage;
     public float Damage
     {
          get {return _damage;}
          set {_damage = value;}
     }
     //implemetation of IActor
}

class Monster : MonoBehavior, IActor
{
    //implemetation of IActor
}

interface IActor
{
    float Hp {get;set;}
    float Damage {get;set;}
}

public Combat (IActor character, IActor character2)
