2）核心代码：
功能1：用W A S D控制小球移动的脚本：
新建一个C#脚本叫做sphereControll，添加到 小球身上。
using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class sphereControll : MonoBehaviour
{// Update is called once per framevoid Update(){if (Input.GetKey(KeyCode.W)){GetComponent<Rigidbody>().AddForce(new Vector3(0, 0, 10));}if (Input.GetKey(KeyCode.S)){GetComponent<Rigidbody>().AddForce(new Vector3(0, 0, -10));}if (Input.GetKey(KeyCode.A)){GetComponent<Rigidbody>().AddForce(new Vector3(-10, 0, 0));}if (Input.GetKey(KeyCode.D)){GetComponent<Rigidbody>().AddForce(new Vector3(10, 0, 0));}if (Input.GetKey(KeyCode.Space)){GetComponent<Rigidbody>().AddForce(new Vector3(0, 10, 0));}}
}
或者：用Input.getAxis控制小球移动的脚本：
using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class sphereControll : MonoBehaviour
{float horizontal;float vertical;public float speed=10;// Update is called once per framevoid Update(){horizontal=Input.GetAxis("Horizontal");vertical=Input.GetAxis("Vertical");GetComponent<Rigidbody>().AddForce(new Vector3(horizontal,0,vertical)*speed);}
}
功能2：摄像机跟随脚本，
新建一个C#脚本叫做CameraController.cs，添加到 摄像机身上。
using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class CameraController : MonoBehaviour
{public GameObject player;Vector3 offset;void Start(){offset = transform.position - player.transform.position;}void Update(){transform.position = player.transform.position + offset;}
}
功能3：物块自动旋转
新建脚本，Rotator.cs，挂到要旋转的物体上。
using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class Rotator : MonoBehaviour
{void Update(){transform.Rotate(new Vector3(15,30,45)*Time.deltaTime);}
}
功能4：碰到即消失。
在小球的脚本中，添加以下代码，若碰到了tag是pickup的物体，则销毁该物体
void OnTriggerEnter(Collider other){if (other.gameObject.tag == "pickup"){Destroy(other.gameObject);} }
