为了制作具有群体性行为的AI，又一次踏上了征途。群体性行为和策略，同个体行为的结构是很像的，但更复杂的是，我们的底层必要有一个机制自动的辅助系统能获得哪些AI应该被形成一个组，为了解决这个问题，我们确立了发起者和响应者。
发起者会检测四周范围响应者，并加入到响应者队列里，最后在这个队列中检测出相应的组，并为这个组的成员分配编号，然后激活这个组所有实体的组行为。
另外，行为节点，行为转化节点的形式也大有不同，定义如下：
public delegate void GroupStateRT(AIEntity pSponsor,AIEntity[] pResponses,int pid); public delegate void GroupStateEnter(AIEntity pSponsor,AIEntity[] pResponses,int pid); public delegate void GroupStateExit(AIEntity pSponsor,AIEntity[] pResponses,int pid); public delegate float GroupStateTransfer(AIEntity pSponsor,AIEntity[] pResponses,int pid);
在一个组行为中，你必须知道，发起者是谁，同组的有谁，以及在这个组中，你扮演的角色编号，你才能完全清楚这个组行为的全部信息，所以本来想要集成在FSM里计划完全泡汤，只能再独立出一个系统，现给出这个系统的一些代码：
