public class Sj : MonoBehaviour { public GameObject player; //前台拖入胶囊 Vector3 rot = new Vector3(0, 0, 0); //先定义一个Vectory3类型的变量rot（0,0,0） public float speed; //这个是鼠标灵敏度 void Start() { void Update() { float MouseX = Input.GetAxis("Mouse X")*speed; float MouseY = Input.GetAxis("Mouse Y")*speed; rot.x = rot.x - MouseY; rot.y = rot.y + MouseX; rot.z = 0; //锁定摄像头移动的角度z轴，防止左右倾斜 transform.eulerAngles = rot; //所有方向设定好后， 摄像头 的角度=rot player.transform.eulerAngles = new Vector3(0, rot.y, 0); //角色角度只能通过MouseX改变大小，也就是锁定rot.y 场景加上碰撞器

Player胶囊身上加上如下代码：

using UnityEngine;
using System.Collections;
public class PlayerMove : MonoBehaviour {
    public float speed;
    // Use this for initialization
    void Start() {
    // Update is called once per frame
    void Update() {
        float MoveX = Input.GetAxis("Horizontal");
        float MoveY = Input.GetAxis("Vertical");
        transform.Translate(new Vector3(MoveX, 0, MoveY) *
            Time.deltaTime * speed);
        if (Input.GetButtonDown("Jump")) {
            Rigidbody rig = GetComponent<Rigidbody>();
            rig.AddForce(new Vector3(0, 0.5f, 0), ForceMode.Impulse);

这是用刚体做的

就可以移动了

1.摄像机成为胶囊的子物体，摄像机上放代码：using UnityEngine;using System.Collections;public class Sj : MonoBehaviour { public GameObject player; //前台拖入胶囊 Vector3 rot = new Vector3(0, 0, 0); / localPosition         Debug.Log("获取状态:" + cubeObj.activeSelf);         Debug.Log("Hirearchy:" + cubeObj.activeInHierarchy);         cubeObj.SetActive(true);
