一个通用高自由度技能系统的设计（三） 功能类基类设计

技能系统功能类分为Comnand，Condition，TargetPicker三个

Command命令类主要进行功能实现

该次实现为Command基类，为以后的命令做扩展

public class Command
{
protected CommandData m_CommandData;

public Command()
{
}

public Command(CommandData data)
{
m_CommandData = data;
}

public virtual void Execute(CommandTrigger trigger, Object arg)
{
}

public virtual Reset()
{
}

public virtual Prepare(CommandTrigger trigger)
{
}
}

Condition为条件判断类，对各种情况进行条件判断

public class Condition
{
protected ConditionData m_ConditionData;

public Condition()
{
}

public Condition(ConditionData data)
{
m_ConditionData = data;
}

public virtual bool Check(CommandTrigger trigger, Object arg)
{
}

public virtual Prepare(CommandTrigger trigger)
{
}
}

TargetPicker为目标选择类，对触发器触发时需要的目标进行选择

public class TargetPicker
{
protected TargetPickerData m_TargetPickerData;
protected List<Entity> mPicked = new List<Entity>();
public TargetPicker()
{
}

public TargetPicker(TargetPickerData data)
{
m_TargetPickerData = data;
}

public List<Entity> GetPicked()
{
return mPicked;
}

public virtual List<Entity> Pick(CommandTrigger trigger, Object arg)
{
return mPicked;
}

public virtual Prepare(CommandTrigger trigger)
{
}
}
