技能追踪其实就是让粒子系统追着敌人打，也就是移动粒子，要想移动粒子要把一个物体上的粒子全部拿到，然后遍历移动，

        float step = speed * Time.deltaTime;
        for(int i = 0; i < size; i++)

            temp[i].position = Vector3.MoveTowards(temp[i].position, A.transform.position, step);
  A.transform.position, step);
        }
        particle.SetParticles(temp,size);
