編碼Army.Add(new PigSquad("The Old Guard", 10, 4));哪里Army是List<Unit>和Pigsquad被定義為public class PigSquad : Unit{    public override bool Dead { get; set; }    public override string Name { get; set;}    public override int Strength { get; set; }    public override int Age { get { return Age; } set { Age = value; Strength += 20 - Age; if (Age > 20) { Dead = true; } } }    public override int Veterancy { get; set; }    public PigSquad()    {    }    public PigSquad(string Name)    {        this.Name = Name;    }    public PigSquad(string Name, int Strength)    {        this.Name = Name;        this.Strength = Strength;    }    public PigSquad(string Name, int Strength, int Age)    {        this.Name = Name;        this.Strength = Strength;        this.Age = Age;    }}運(yùn)行時(shí)使Unity編輯器崩潰。我不知道為什么會(huì)這樣。在這方面的任何幫助將不勝感激。
