Unity第一人称移动和观察

创建一个可以自由移动的第一人称视角

人物通过WSAD进行前后左右移动，通过鼠标右键进行旋转

Step1:创建一个Player玩家，在节点下加两个子物体，一个摄像头和一个Capsule充当身体

Step2:创建一个脚本挂载在Player节点下，再在这个Player物体下加上Character Controller脚本

Step3:该脚本内容如下

using UnityEngine;/// <summary>
/// 人物移动脚本
/// 直接引用Character的Move方法
/// </summary>
public class PlayerMove : MonoBehaviour
{//键盘public float speed = 30F;public float jumpSpeed = 5.0F;public float gravity = 5.0F;private Vector3 moveDirection;private CharacterController characterController;//鼠标public float mousespeed = 3f;public float minmouseY = -45f;public float maxmouseY = 45f;public Transform playerCamera;private Vector3 oldMousePos;private Vector3 newMousePos;private void OnEnable(){characterController = GetComponent<CharacterController>();}private void FixedUpdate(){if (Input.GetMouseButton(1)){//把当前右键鼠标点的位置先存储起来newMousePos = Input.mousePosition;//再把每一帧刚开始的位置和上一帧的位置做一个差值Vector3 dis = newMousePos - oldMousePos;//X，Y方向上位移的距离就是这个差值的x，y分量*鼠标移动速度float angleX = dis.x * mousespeed;float angleY = dis.y * mousespeed;//然后再根据分量差值进行旋转transform.Rotate(new Vector3(-angleY, 0, 0), Space.Self);transform.Rotate(new Vector3(0, angleX, 0), Space.World);}if(characterController.isGrounded){moveDirection = new Vector3(Input.GetAxis("Horizontal"), 0, Input.GetAxis("Vertical"));moveDirection = transform.TransformDirection(moveDirection);moveDirection *= speed;if (Input.GetButton("Jump")){moveDirection.y = jumpSpeed;}}moveDirection.y = moveDirection.y - gravity * Time.deltaTime;//使用characterController的Move方法对物体进行移动，参数就是移动方向 * 时间characterController.Move(moveDirection * Time.deltaTime);//更新鼠标的下一帧位置oldMousePos = Input.mousePosition;}
}

运行即可
