想做成点击移动，并且摄像头可以根据鼠标位置有限制的旋转

Step 1 - 点击移动

参照Project02

完成~

using UnityEngine.AI;

public class PlayerMovement : MonoBehaviour
{
    public NavMeshAgent agent;

    // Start is called before the first frame update
    void Start()
    {
        agent = GetComponent<NavMeshAgent>();
    }

    // Update is called once per frame
    void Update()
    {
        // Click to Move
        if(Input.GetMouseButtonDown(0)){
            RaycastHit hit;
            Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
            if(Physics.Raycast(ray, out hit, Mathf.Infinity)){
                agent.SetDestination(hit.point);
            }
        }
    }
}

Step 2 - 旋转摄像头

鼠标转向不是很方便，顺便加了方向键旋转

    private float xRotation = 0f;

    // Start is called before the first frame update
    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {
        // Get mouse position
        float mouseX = Input.GetAxis("Mouse X") * mouseSensitivity * Time.deltaTime;
        float mouseY = Input.GetAxis("Mouse Y") * mouseSensitivity * Time.deltaTime;

        // Get key inout
        float keyX = Input.GetAxis("Horizontal") * keySensitivity * Time.deltaTime;

        Debug.Log(mouseX);
        Debug.Log(keyX);

        // Rotate camera up and down
        xRotation -= mouseY;
        xRotation = Mathf.Clamp(xRotation, -30f, 30f);
        transform.localRotation = Quaternion.Euler(xRotation, 0f, 0f);

        // Rotate player left and right
        player.Rotate(Vector3.up * (mouseX + keyX));
    }
}

耶(＾－＾)V

目前这个移动方式很满意，暂时就这样

下一步可以搭场景啦~
