建立一个 3D 专案

先按下工具列的档案>另存为… 档名输入 Scene1，另存成新的 Scene

在阶层视窗按下滑鼠右键 > 3D 物件 > 平面，新增一块地板

在阶层视窗按下滑鼠右键 > 3D 物件 > 球体，新增一颗球

将 Sphere 物件变更名称为 Player

将 Player 物件变更属性 Y = 3

调整 MainCamera 物件的属性 Y = 1；Z = -6

对 Player 物件增加元件 > 物理 > Rigidbody

建立一个 Scripts 资料夹

建立一个 C# 脚本，名为 PlayerScript

编辑脚本并输入以下程式码

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class PlayerScript : MonoBehaviour
{
    // Start is called before the first frame update
    Rigidbody rb;
    float speed = 5;
    void Start()
    {
        rb = GetComponent<Rigidbody>();
    }

    // Update is called once per frame
    void Update()
    {

    }

    private void FixedUpdate()
    {
        float moveHorizontal = Input.GetAxis("Horizontal");
        float moveVertical = Input.GetAxis("Vertical");
        Vector3 movement = new Vector3(moveHorizontal, 0.0f, moveVertical);
        rb.AddForce(movement * speed);
    }
}

将脚本加入 Player 物件中

新建一个脚本，名为 CameraScript，编辑并输入以下程式码

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class CameraScript : MonoBehaviour
{
    // Start is called before the first frame update
    private GameObject player;
    Vector3 offset;

    void Start()
    {
        player = GameObject.Find("Player");
        offset = transform.position - player.transform.position;
    }
    
    private void LateUpdate()
    {
        transform.position = player.transform.position + offset;
    }

    // Update is called once per frame
    void Update()
    {
        
    }
}

将 CameraScript 脚本拉进 MainCamera 物件
