前面，學了物體的移動功能，現(xiàn)在來學一下C#實現(xiàn)鼠標控制攝像機(視角)移動。
代碼如下：
C#腳本(在Unity 5.5.1 下能運行)：
using System.Collections;using System.Collections.Generic;using UnityEngine;public class MouseView : MonoBehaviour { public enum RotationAxes { MouseXAndY = 0, MouseX = 1, MouseY = 2 } public RotationAxes m_axes = RotationAxes.MouseXAndY; public float m_sensitivityX = 10f; public float m_sensitivityY = 10f; // 水平方向的 鏡頭轉向 public float m_minimumX = -360f; public float m_maximumX = 360f; // 垂直方向的 鏡頭轉向 (這里給個限度 最大仰角為45°) public float m_minimumY = -45f; public float m_maximumY = 45f; float m_rotationY = 0f; // Use this for initialization void Start () { // 防止 剛體影響 鏡頭旋轉 if (GetComponent<Rigidbody>()) { GetComponent<Rigidbody> ().freezeRotation = true; } } // Update is called once per frame void Update () { if (m_axes == RotationAxes.MouseXAndY) { float m_rotationX = transform.localEulerAngles.y + Input.GetAxis ("Mouse X") * m_sensitivityX; m_rotationY += Input.GetAxis ("Mouse Y") * m_sensitivityY; m_rotationY = Mathf.Clamp (m_rotationY, m_minimumY, m_maximumY); transform.localEulerAngles = new Vector3 (-m_rotationY, m_rotationX, 0); } else if (m_axes == RotationAxes.MouseX) { transform.Rotate (0, Input.GetAxis ("Mouse X") * m_sensitivityX, 0); } else { m_rotationY += Input.GetAxis ("Mouse Y") * m_sensitivityY; m_rotationY = Mathf.Clamp (m_rotationY, m_minimumY, m_maximumY); transform.localEulerAngles = new Vector3 (-m_rotationY, transform.localEulerAngles.y, 0); } }}調用時，只需把該腳本綁定給物體即可。這里是綁定攝像機，以攝像機為第一人稱視角轉動。
以上就是本文的全部內容，希望對大家的學習有所幫助，也希望大家多多支持武林網。
