鼠标点击坐标

想用鼠标点击控制镜头和角色移动，坐标一直有问题

原来点击后有好几种坐标，如下：

public class CameraController : MonoBehaviour
{
    public Vector3 CameraPosition;

    Camera _this;

    void Start()
    {
        _this = gameObject.GetComponent<Camera>();
        CameraPosition = _this.transform.position;
    }

    void Update()
    {
        getMousePos();
    }

    void getMousePos()
    {
        Vector3 mousePos = Input.mousePosition;

        bool mouseInside = (mousePos.x >= 0) &&
                               (mousePos.x < Screen.width) &&
                               (mousePos.y >= 0) &&
                               (mousePos.y < Screen.height);

        Vector3 worldPos = Camera.main.ScreenToWorldPoint(mousePos);

        if (Input.GetMouseButtonDown(0) && mouseInside)
        {
            //print("Input.mousePosition: " + Input.mousePosition);
            //print("Input.mousePosition world to viewport: " + Camera.main.WorldToViewportPoint(Input.mousePosition));
            //print("Input.mousePosition world to screen: " + Camera.main.WorldToScreenPoint(Input.mousePosition));
            //print("Input.mousePosition Viewport To Screen: " + Camera.main.ViewportToScreenPoint(Input.mousePosition));
            //print("Input.mousePosition Viewport To World: " + Camera.main.ViewportToWorldPoint(Input.mousePosition));
            //print("Input.mousePosition Screen To Viewport " + Camera.main.ScreenToViewportPoint(Input.mousePosition));
            print("Input.mousePosition Screen To World: " + worldPos);
            
            // 移动窗口视角
             moveCamera(mousePos);
        }

    }

    void moveCamera(Vector3 mousePos)
    {
        mousePos.z = -1;
        _this.transform.position = mousePos;

    }
}

使用鼠标控制移动

这个脚本还有大问题，主角有时候无法停止，点击的终点不太精准。

    void move_ani()
    {
        //float h = Input.GetAxis("Horizontal"); // A D
        //float v = Input.GetAxis("Vertical");    // W S
        //_moveVec.Set(h, v, 0);


        if (Input.GetMouseButtonDown(0))
        {
            _targetPos = Camera.main.ScreenToWorldPoint(Input.mousePosition);
            _moveVec = _targetPos - transform.position;
        }

        if (_moveVec != Vector3.zero)
        {
            float dot = Vector3.Dot(_moveVec, Vector3.right);
            if (dot != 0) // 左右走，改变朝向
            {
                if (dot > 0) // 向右
                    _ani.SetBool("LookLeft", false);
                else if (dot < 0)
                    _ani.SetBool("LookLeft", true);
            }
            _ani.SetFloat("Speed", _moveVec.magnitude);

            if (dot != 0)
            {
                _rig.MovePosition(transform.position + _moveVec * MoveSpeed * Time.deltaTime);
            }
        }

        if(Mathf.Abs(transform.position.magnitude - _moveVec.magnitude) < 0.1)
        {
            _moveVec = Vector3.zero;
            _ani.SetFloat("Speed", 0);
        }

    }

第三版，鼠标点击精准了，又有个新问题，撞到障碍物的时候就会转起来，之后看书解决了，把刚体的z轴固定就不会转了。

撞到障碍物就转起来了

    void move_ani()
    {
        if (Input.GetMouseButtonDown(0))
        {
            _targetPos = Camera.main.ScreenToWorldPoint(Input.mousePosition);
            _targetPos.z = 0;
            _moveVec = _targetPos - transform.position;
        }

        if (_moveVec != Vector3.zero)
        {
            float dot = Vector3.Dot(_moveVec, Vector3.right);
            if (dot != 0) // 左右走，改变朝向
            {
                if (dot > 0) // 向右
                    _ani.SetBool("LookLeft", false);
                else if (dot < 0)
                    _ani.SetBool("LookLeft", true);
            }
            _ani.SetFloat("Speed", _moveVec.magnitude);

            if (dot != 0)
            {
                _rig.MovePosition(transform.position + _moveVec * MoveSpeed * Time.deltaTime);
                //_rig.MovePosition(_targetPos);
            }
        }

        if(Mathf.Abs(transform.position.magnitude - _targetPos.magnitude) < 0.1)
        {
            _moveVec = Vector3.zero;
            _ani.SetFloat("Speed", 0);
        }
    }
