Navmesh随鼠标旋转

Question

我想旋转我的NavigationMeshAgent参照鼠标的位置。下面是我这样做的代码。

public class Navcontroller : MonoBehaviour
{
    // Start is called before the first frame update

    private NavMeshAgent _agent;
    void Start()
    {
        _agent = GetComponent<NavMeshAgent>();
    }

    // Update is called once per frame
    void Update()
    {
        
        float horInput = Input.GetAxis("Horizontal");
        float verInput = Input.GetAxis("Vertical");
        
        Vector3 movement = new Vector3(horInput, 0f, verInput);
        Vector3 moveDestination = transform.position + movement;
        _agent.destination = moveDestination;

    }
}

不巧的是，旋转是奇怪的，当我移动鼠标的时候，它可以看遍整个地方。我遗漏了什么？

更新：

我已经用鼠标的位置更新了我的代码如下，

public class Navcontroller : MonoBehaviour

{

// Start is called before the first frame update

private NavMeshAgent _agent;
float mouseX, mouseY;
float rotationSpeed = 1;

void Start()
{
    _agent = GetComponent<NavMeshAgent>();
    
    Cursor.visible = false;
    Cursor.lockState = CursorLockMode.Locked;

}

// Update is called once per frame
void Update()
{
    

    float horInput = Input.GetAxis("Horizontal");
    float verInput = Input.GetAxis("Vertical");
    
    Vector3 movement = new Vector3(horInput, 0f, verInput);
    Vector3 moveDestination = transform.position + movement ;
    
    mouseX += Input.GetAxis("Mouse X") * rotationSpeed;
    mouseY -= Input.GetAxis("Mouse Y") * rotationSpeed;
    
    _agent.destination = moveDestination;

    _agent.transform.rotation = Quaternion.Euler(mouseY, mouseX, 0);

}

}

现在代理和相机一起旋转。但这名特工并没有朝他所看到的方向移动。

基于评论

Vector3 mousePosition = Input.mousePosition; // Get mouse position
mousePosition = Camera.main.ScreenToWorldPoint(mousePosition); //Transfom it to game space - form screen space
Vector2 direction = new Vector2(
mousePosition.x - transform.position.x,
mousePosition.y - transform.position.y
); // create new direction

transform.up = direction; // Rotate Z axis

因为基于评论，这与NavigationMeshAgent或AI无关。那么，要向前迈进，你要做的

if(Input.GetKey(Key.W)){
    transform.forward += Speed * Time.deltaTime;
}

编辑

您的_agent.destination = moveDestination;需要匹配您的旋转，所以您需要乘以它的旋转。_agent.destination = Quaternion.Euler(mouseY, mouseX, 0) * moveDestination，moveDestination应该相对于它的旋转(不是像现在这样绝对的)，所以最好使用_agent.destination = Quaternion.Euler(mouseY, mouseX, 0) * Vector3.forward
