Explaining my problem

我正在使用 Unity3D 引擎编写手机游戏。对于我的玩家移动，我使用 NavMeshAgent，因为它对我来说是最简单、最有效的方式。但是当我按下播放按钮并让我的播放器移动时，动作是生涩的，看起来一点也不愉快。

你有解决这个问题的办法吗？！预先感谢您的回答！ ^^

My code

这是我的代码：

Player.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.AI;

public class Player : MonoBehaviour
{
    NavMeshAgent agent;
    Touch touch;
    RaycastHit hit;
    Ray ray;

    // START FUNCTION
    private void Start()
    {
        agent = GetComponent<NavMeshAgent>();
    }

    // UPDATE FUNCTION
    private void Update()
    {
        // TOUCH DETECTION
        if (Input.touchCount > 0)
        {
            touch = Input.GetTouch(0);

            // A FINGER TOUCHED THE SCREEN
            if (touch.phase == TouchPhase.Began)
            {
                // RETURN X, Y AND Z WORLD POS OF THE TOUCH SCREEN POS
                ray = Camera.main.ScreenPointToRay(touch.position);

                if (Physics.Raycast(ray, out hit))
                {
                    if (hit.collider != null)
                    {
                        // MOVING PLAYER TO THE HIT POS
                        Vector3 hitVec = new Vector3(hit.point.x, hit.point.y + (GetComponent<Collider>().bounds.size.y / 2), hit.point.z);
                        agent.SetDestination(hitVec);
                    }
                }
            }
        }

        // SAME CODE USING MOUSE BUTTON
#if UNITY_EDITOR

        if (Input.GetMouseButton(0))
        {
            ray = Camera.main.ScreenPointToRay(Input.mousePosition);

            if (Physics.Raycast(ray, out hit))
            {
                if (hit.collider != null)
                {
                    Vector3 hitVec = new Vector3(hit.point.x, hit.point.y + (GetComponent<Collider>().bounds.size.y / 2), hit.point.z);
                    agent.SetDestination(hitVec);
                }
            }
        }

#endif
    }
}

CameraFollow.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

// BRACKEYS CAMERA FOLLOW SCRIPT WITHOUT THE LOOKAT METHODE
public class CameraFollow : MonoBehaviour
{
    public Transform target;

    public float smoothSpeed = 0.2f;
    public Vector3 offset;

    void FixedUpdate()
    {
        Vector3 desiredPosition = target.position + offset;
        Vector3 smoothedPosition = Vector3.Lerp(transform.position, desiredPosition, smoothSpeed);
        transform.position = smoothedPosition;
    }
}

Answer 1

问题不在于导航网格控制器，而是相机跟随脚本。

您可以尝试的一件事是仅使用 desiredPosition 或使用 Vector3.SmoothDamp:

移动相机位置

private Vector3 velocity;

void LateUpdate(){

...

        Vector3 desiredPosition = target.position + offset;
        Vector3 smoothedPosition = Vector3.SmoothDamp(transform.position, desiredPosition, ref velocity, smoothSpeed);
        transform.position = smoothedPosition;
}
