【问题描述】：

我正在创建 tample run，就像无尽的跑步者一样，我可以成功地一起旋转播放器中的相机，但我希望相机像其他游戏一样平稳移动。请注意在更新方法中调用移动函数

    }




    void UpdateAnimator(bool jump)

    if (m_Crouching) {
        m_Animator.SetBool ("Crouch", true);

    }

            count +=1;
        if(count>100)

    }



    public void OnAnimatorMove()
    {

        if (m_IsGrounded && Time.deltaTime > 0)
        {
            Vector3 v = (m_Animator.deltaPosition * m_MoveSpeedMultiplier) / Time.deltaTime;

            // we preserve the existing y part of the current velocity.
            v.y = m_Rigidbody.velocity.y;
            m_Rigidbody.velocity = v;
        }
    }

    public void setTurn(bool t){
        turn = t;
    }

这是 camara 脚本

void Start () {
    Vector3 angles = transform.eulerAngles;
    x = angles.x;
    y = angles.y;
}

void LateUpdate () {
    if(!target)
        return;

    y = target.eulerAngles.y;


    // ROTATE CAMERA:
    Quaternion rotation = Quaternion.Euler (x, y, 0);
        transform.rotation = rotation;

    // POSITION CAMERA:

        transform.position = target.position - (rotation * Vector3.forward * distance + new Vector3(0,-targetHeight,0));

}

【解决方案1】：

你试过用lerp移动相机吗？它应该对相机的当前位置和目标位置进行插值，从而实现更平滑的移动。

我在上面链接的文档页面上有一个示例代码，因此实现起来应该不会太难。您所要做的就是：

transform.position = Vector3.Lerp(currentPositionGoesHere, targetPositionGoesHere, floatNumberHere);

浮动将决定两个位置之间过渡的平滑程度。
