unity---摄像机跟随

摄像头跟随#

防止计算机一直进行差值计算，影响计算机性能#

加入插值函数能够让摄像机灵动起来

脚本#

  void LateUpdate()
{
    tragetPosition = follow.position+Vector3.up*distanceUp-follow.forward*distanceAway;
    if(Vector3.Distance(this.tragetPosition,follow.transform.position)<0.05f){
            this.gameObject.transform.position=tragetPosition;
    }
    else {
        transform.position=Vector3.Lerp(transform.position,tragetPosition,Time.deltaTime*smooth);
    }
}
