這篇文章主要為大家詳細(xì)介紹了Unity實(shí)現(xiàn)人物旋轉(zhuǎn)和移動(dòng)效果，文中示例代碼介紹的非常詳細(xì)，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

本文實(shí)例為大家分享了Unity實(shí)現(xiàn)人物旋轉(zhuǎn)和移動(dòng)的具體代碼，供大家參考，具體內(nèi)容如下

旋轉(zhuǎn)

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
 
public class MouseLook : MonoBehaviour {
 public enum RotationAxes
 {
 MouseXandY = 0,
 MouseX = 1,
 MouseY = 2
 }
 
 public RotationAxes axes = RotationAxes.MouseXandY;
 
 public float sensitivityHor = 9.0f;
 public float sensitivityVert = 9.0f;
 
 public float minVert = -45.0f;
 public float maxVert = 45.0f;
 
 private float _rotationX = 0;
 
 // Use this for initialization
 void Start () {
 Rigidbody body = GetComponent<Rigidbody> ();
 if (body != null) {
  body.freezeRotation = true;
 }
 }
 
 // Update is called once per frame
 void Update () {
 //水平旋轉(zhuǎn)就是以Y軸作為旋轉(zhuǎn)軸旋轉(zhuǎn)，鼠標(biāo)移動(dòng)量為偏移量
 if (axes == RotationAxes.MouseX) {
  transform.Rotate (0, Input.GetAxis("Mouse X") * sensitivityHor, 0);//通過(guò)“增加”旋轉(zhuǎn)角度進(jìn)行旋轉(zhuǎn)（X,Y,Z為對(duì)應(yīng)方向的增加量）,一般用于無(wú)限制旋轉(zhuǎn)
 } else if (axes == RotationAxes.MouseY) {
  _rotationX -= Input.GetAxis ("Mouse Y") * sensitivityVert;
  _rotationX = Mathf.Clamp (_rotationX, minVert, maxVert);//限制_rotationX的值在minVert與minVert之間
  float rotationY = transform.localEulerAngles.y;
  //Debug.Log ("rotationX:"+_rotationX+","+Input.GetAxis ("Mouse Y") * sensitivityVert);
  transform.localEulerAngles = new Vector3(_rotationX, rotationY, 0);//直接“設(shè)置”旋轉(zhuǎn)角度進(jìn)行旋轉(zhuǎn)，一般用于有限制旋轉(zhuǎn)
 } else {
  _rotationX -= Input.GetAxis ("Mouse Y") * sensitivityVert;
  _rotationX = Mathf.Clamp (_rotationX, minVert, maxVert);
  float delta = Input.GetAxis ("Mouse X") * sensitivityHor;
  float rotationY = transform.localEulerAngles.y + delta;
  transform.localEulerAngles = new Vector3(_rotationX, rotationY, 0);
 }
 }
}

移動(dòng)

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
 
[RequireComponent(typeof(CharacterController))]//如果對(duì)象沒(méi)有該組件，則創(chuàng)建一個(gè)
[AddComponentMenu("Control Script/FPS Input")]//可以在Add Component查到
 
public class FPSInput : MonoBehaviour {
 
 private CharacterController _characterController;
 public float speed = 10.0f;
 public float gravity = -9.8f;
 // Use this for initialization
 void Start () {
 _characterController = GetComponent<CharacterController>();//獲取對(duì)象里的某一組件
 }
 
 // Update is called once per frame
 void Update () {
 float deltaX = Input.GetAxis ("Horizontal") * speed;
 float deltaZ = Input.GetAxis ("Vertical") * speed;
 Vector3 movement = new Vector3 (deltaX, 0, deltaZ);
 movement = Vector3.ClampMagnitude (movement, speed);//保持各方向的速度相同
 movement.y = gravity;
 movement = movement * Time.deltaTime;//向量可以直接乘以一個(gè)數(shù)，Time.deltaTime確保在每臺(tái)計(jì)算機(jī)上的速度相同
 movement = transform.TransformDirection (movement);//將本地坐標(biāo)轉(zhuǎn)換為世界坐標(biāo)
 _characterController.Move(movement);//通過(guò)CharacterController進(jìn)行移動(dòng)而不是transform.Translate
 }
}

問(wèn)題

人物移動(dòng)到父容器的邊緣時(shí)，人物的移動(dòng)會(huì)產(chǎn)生偏移（甚至飛起來(lái)）。將父容器擴(kuò)大，使人物無(wú)法接近邊緣則不會(huì)有異常。

父容器比較大
