            anim.SetFloat("AnglierSpeed",0,AngleDampTime,Time.deltaTime);
   }
   else
   {
    float angle =Vector3.Angle(transform.forward,navAgent.desiredVelocity);
    float angleRad = 0;
    if (angle > 90)
     {
       anim.SetFloat("Speed", 0,SpeedDampTime,Time.deltaTime);
     }
     else
     {
      Vector3 projection =Vector3.Project(navAgent.desiredVelocity, transform.forward);
      anim.SetFloat("Speed",projection.magnitude,SpeedDampTime,Time.deltaTime);
     }
     angleRad = Mathf.Deg2Rad;
     Vector3 crossRes = Vector3.Cross(transform.forward,navAgent.desiredVelocity);
     if (crossRes.y < 0)
       {
           angleRad = -angleRad;
       }
       anim.SetFloat("AnglierSpeed",angleRad,AngleDampTime,Time.deltaTime);

    }

具体原因我也找不太清，代码和老师的一样。但是这个机器人动作却不按Nav Mesh Agent里面所定的点走，视频里用的是4.6版本，我是2017 1.1p4版本，我怀疑是版本不一样导致的动画播放的不一样，因为有的视频里的方法弃用了，我另写的方法改的代码

这个机器人一直在原地往前蹭，nav所定的点和他方向一样时他才会走，而且走得慢，走的不远就停了，这个问题卡了我好久了，代码发的太多了可能老师看着费劲，我q651826284，如果老师有时间帮我解决一下就太感谢了！
