Unity 多人游戏开发复习笔记

人物移动脚本

public class Motion : MonoBehaviour
{
    #region Fields
    public float speed;

    private Rigidbody rig;
    #endregion

    #region MonoBehaviour CallBacks
    private void Start()
    {
        Camera.main.enabled = false;
        rig = GetComponent<Rigidbody>();
    }

    // 多人游戏下同步玩家位置时建议使用FixedUpdate
    void FixedUpdate()
    {
        // 玩家移动
        float t_hmove = Input.GetAxis("Horizontal");
        float t_vmove = Input.GetAxis("Vertical");

        Vector3 t_direction = new Vector3(t_hmove, 0, t_vmove);
        t_direction.Normalize();

        rig.velocity = transform.TransformDirection(t_direction) * speed * Time.deltaTime;
    }

查看四周脚本

public class Look : MonoBehaviour
{
    #region Fields
    public Transform player;
    public Transform cams;

    public float xSensitivity;
    public float ySensitivity;
    public float maxAngle;

    private Quaternion camCenter;
    #endregion

    #region MonoBehaviour CallBacks
    void Start()
    {
        camCenter = cams.localRotation;
    }

    void Update()
    {
        SetY();
        SetX();
    }
    #endregion

    #region Methods
    // 上下查看
    void SetY()
    {
        float t_input = Input.GetAxis("Mouse Y") * ySensitivity * Time.deltaTime;
        Quaternion t_adj = Quaternion.AngleAxis(t_input, -Vector3.right);
        Quaternion t_detal = cams.localRotation * t_adj;

        // 限制上下查看的最大角度
        if (Quaternion.Angle(camCenter, t_detal) < maxAngle)
        {
            cams.localRotation = t_detal;
        }
    }
    // 左右查看
    void SetX()
    {
        float t_input = Input.GetAxis("Mouse X") * xSensitivity * Time.deltaTime;
        Quaternion t_adj = Quaternion.AngleAxis(t_input, Vector3.up);
        Quaternion t_detal = player.localRotation * t_adj;

        player.localRotation = t_detal;
