I'm developing a game. I want to have game entities each have their own Damage() function. When called, they will calculate how much damage they want to do:
public class CombatantGameModel : GameObjectModel
{
public int Health { get; set; }
/// <summary>
/// If the attack hits, how much damage does it do?
/// </summary>
/// <param name="randomSample">A random value from [0 .. 1]. Use to introduce
randomness in the attack's damage.</param>
/// <returns>The amount of damage the attack does</returns>
public delegate int Damage(float randomSample);
public CombatantGameModel(GameObjectController controller) : base(controller) {}
}
public class CombatantGameObject : GameObjectController
{
private new readonly CombatantGameModel model;
public new virtual CombatantGameModel Model
{
get { return model; }
}
public CombatantGameObject()
{
model = new CombatantGameModel(this);
}
}
However, when I try to call that method, I get a compiler error:
/// <summary>
/// Calculates the results of an attack, and directly updates the GameObjects involved.
/// </summary>
/// <param name="attacker">The aggressor GameObject</param>
/// <param name="victim">The GameObject under assault</param>
public void ComputeAttackUpdate(CombatantGameObject attacker, CombatantGameObject victim)
{
if (worldQuery.IsColliding(attacker, victim, false))
{
victim.Model.Health -= attacker.Model.Damage((float) rand.NextDouble()); // error here
Debug.WriteLine(String.Format("{0} hits {1} for {2} damage", attacker, victim, attackTraits.Damage));
}
}
The error is:
'Damage': cannot reference a type
through an expression; try
'HWAlphaRelease.GameObject.CombatantGameModel.Damage'
instead
What am I doing wrong?
