前面已经给读者介绍了两个类，这两个类并没有具体对象的行为表示，给人的感觉就是一个抽象的类，接下来它们的孩子类的编写，也就是具体的类了。在这里介绍一下设计思路，游戏中的角色和怪物也有共同的属性，比如Buff、Debuff、伤害、移动等等，将这些共同的属性可以放在我们已经规划好的BaseCharacter类中，该类主要实现的就是英雄和怪物的基础属性和方法，代码如下所示：

public class BaseCharacter:BaseActor { public GameObject m_MPoint; /// <summary> /// 攻击特效最长持续时间 /// </summary> protected float m_AttackedEffTimeMax; /// <summary> /// /// </summary> protected bool m_bCameraFrustum;
