Unity|小游戏复刻|见缝插针2(C#)

控制针的运动

1. 新建一个Pin脚本
   

2. 将Pin脚本拖到针Pin的下面
   

3. 保存代码

using UnityEngine;

public class Pin : MonoBehaviour
{
    public float speed = 5;
    private bool isFly = false;
    private bool isReach = false;
    private Transform startPosition;


    // Start is called once before the first execution of Update after the MonoBehaviour is created
    void Start()
    {
        startPosition = GameObject.Find("StartPosition").transform;
    }

    // Update is called once per frame
    void Update()
    {
        if (isFly == false)
        {
            if (isReach == false)
            {
                transform.position = Vector3.MoveTowards(transform.position, startPosition.position, speed * Time.deltaTime) ;
                if (Vector3.Distance(transform.position, startPosition.position) < 0.05f )
                {
                    isReach = true ;
                }
            }
        }

    }
}

控制针的插入

Pin.C#

using UnityEngine;

public class Pin : MonoBehaviour
{
    public float speed = 5;
    private bool isFly = false;
    private bool isReach = false;
    private Transform startPosition;
    private Transform circle;


    // Start is called once before the first execution of Update after the MonoBehaviour is created
    void Start()
    {
        startPosition = GameObject.Find("StartPosition").transform;
        circle = GameObject.Find("Circle").transform;
    }

    // Update is called once per frame
    void Update()
    {
        if (isFly == false)
        {
            if (isReach == false)
            {
                transform.position = Vector3.MoveTowards(transform.position, startPosition.position, speed * Time.deltaTime) ;
                if (Vector3.Distance(transform.position, startPosition.position) < 0.05f )
                {
                    isReach = true ;
                }
            }
        }
        else
        {
            transform.position = Vector3.MoveTowards(transform.position, circle.position, speed * Time.deltaTime);
            
        }

    }

    public void StartFly()
    {
        isFly = true ;
        isReach = true;

    }
}

GameManager.C#

using UnityEngine;

public class GameManager : MonoBehaviour
{
    private Transform startPosition;
    private Transform spawnPosition;
    private Pin currentPin;

    public GameObject pinPrefab;

    // Start is called once before the first execution of Update after the MonoBehaviour is created
    void Start()
    {
        startPosition = GameObject.Find("StartPosition").transform;
        spawnPosition = GameObject.Find("SpawnPosition").transform;
        SpawnPin();
    }

    // Update is called once per frame
    void Update()
    {
        if (Input.GetMouseButtonDown(0))
        {
            currentPin.StartFly();
        }
    }

    void SpawnPin()
    {
        currentPin = GameObject.Instantiate(pinPrefab, spawnPosition.position, pinPrefab.transform.rotation).GetComponent<Pin>();
    }
}

控制针的位置和连续发射

1. 计算Circle和Pin此时位置的y值，为2和0.46，差为1.54
   

Pin

using UnityEngine;

public class Pin : MonoBehaviour
{
    public float speed = 5;
    private bool isFly = false;
    private bool isReach = false;
    private Transform startPosition;

    private Vector3 targetCirclePos;
    private Transform circle;


    // Start is called once before the first execution of Update after the MonoBehaviour is created
    void Start()
    {
        startPosition = GameObject.Find("StartPosition").transform;
        circle = GameObject.Find("Circle").transform;
        targetCirclePos = circle.position;
        targetCirclePos.y -= 1.54f;
    }

    // Update is called once per frame
    void Update()
    {
        if (isFly == false)
        {
            if (isReach == false)
            {
                transform.position = Vector3.MoveTowards(transform.position, startPosition.position, speed * Time.deltaTime) ;
                if (Vector3.Distance(transform.position, startPosition.position) < 0.05f )
                {
                    isReach = true ;
                }
            }
        }
        else
        {
            transform.position = Vector3.MoveTowards(transform.position, targetCirclePos, speed * Time.deltaTime);
            
        }

    }

    public void StartFly()
    {
        isFly = true ;
        isReach = true;

    }
}

使针跟随小球运动

Pin

using UnityEngine;

public class Pin : MonoBehaviour
{
    public float speed = 5;
    private bool isFly = false;
    private bool isReach = false;
    private Transform startPosition;

    private Vector3 targetCirclePos;
    private Transform circle;


    // Start is called once before the first execution of Update after the MonoBehaviour is created
    void Start()
    {
        startPosition = GameObject.Find("StartPosition").transform;
        circle = GameObject.Find("Circle").transform;
        targetCirclePos = circle.position;
        targetCirclePos.y -= 1.54f;
    }

    // Update is called once per frame
    void Update()
    {
        if (isFly == false)
        {
            if (isReach == false)
            {
                transform.position = Vector3.MoveTowards(transform.position, startPosition.position, speed * Time.deltaTime) ;
                if (Vector3.Distance(transform.position, startPosition.position) < 0.05f )
                {
                    isReach = true ;
                }
            }
        }
        else
        {
            transform.position = Vector3.MoveTowards(transform.position, targetCirclePos, speed * Time.deltaTime);
            if (Vector3.Distance(transform.position,targetCirclePos) < 0.05f)
            {
                transform.position = targetCirclePos;
                transform.parent = circle;
                isFly = false;
            }
        }
    }

    public void StartFly()
    {
        isFly = true ;
        isReach = true;

    }
}

继续生成针

GameManager

using UnityEngine;

public class GameManager : MonoBehaviour
{
    private Transform startPosition;
    private Transform spawnPosition;
    private Pin currentPin;

    public GameObject pinPrefab;

    // Start is called once before the first execution of Update after the MonoBehaviour is created
    void Start()
    {
        startPosition = GameObject.Find("StartPosition").transform;
        spawnPosition = GameObject.Find("SpawnPosition").transform;
        SpawnPin();
    }

    // Update is called once per frame
    void Update()
    {
        if (Input.GetMouseButtonDown(0))
        {
            currentPin.StartFly();
            SpawnPin();
        }
    }

    void SpawnPin()
    {
        currentPin = GameObject.Instantiate(pinPrefab, spawnPosition.position, pinPrefab.transform.rotation).GetComponent<Pin>();
    }
}

针的碰撞和游戏结束

1. 给Pin的针头添加Circle Collider 2D，勾上触发器，再添加rigidbody 2D，重力设为0
   

2. 添加PinHead脚本，将其挂载到PinHead上，给PinHead添加上自己添加的PinHead标签
   

3. 进行碰撞检测

   PinHead

using UnityEngine;

public class PinHead : MonoBehaviour
{
    private void OnTriggerEnter2D(Collider2D collision)
    {
        if (collision.tag == "PinHead")
        {
            GameObject.Find("GameManager").GetComponent<GameManager>().GameOver();
        }
    }
}

GameManager

using UnityEngine;
using UnityEngine.UIElements;

public class GameManager : MonoBehaviour
{
    private Transform startPosition;
    private Transform spawnPosition;
    private Pin currentPin;
    private bool isGameOver = false;

    public GameObject pinPrefab;

    // Start is called once before the first execution of Update after the MonoBehaviour is created
    void Start()
    {
        startPosition = GameObject.Find("StartPosition").transform;
        spawnPosition = GameObject.Find("SpawnPosition").transform;
        SpawnPin();
    }

    // Update is called once per frame
    void Update()
    {
        if (isGameOver) return;
        if (Input.GetMouseButtonDown(0))
        {
            currentPin.StartFly();
            SpawnPin();
        }
    }

    void SpawnPin()
    {
        currentPin = GameObject.Instantiate(pinPrefab, spawnPosition.position, pinPrefab.transform.rotation).GetComponent<Pin>();
    }

    public void GameOver()
    {
        if (isGameOver) return;

        GameObject.Find("Circle").GetComponent<RotateSelf>().enabled = false;

        isGameOver = true;
    }
}

分数增加

GameManager

using UnityEditor.Tilemaps;
using UnityEngine;
using UnityEngine.UI;
using UnityEngine.UIElements;
using TMPro;

public class GameManager : MonoBehaviour
{
    private Transform startPosition;
    private Transform spawnPosition;
    private Pin currentPin;
    private bool isGameOver = false;
    private int score = 0;

    public TextMeshProUGUI scoreText;
    public GameObject pinPrefab;

    // Start is called once before the first execution of Update after the MonoBehaviour is created
    void Start()
    {
        startPosition = GameObject.Find("StartPosition").transform;
        spawnPosition = GameObject.Find("SpawnPosition").transform;
        SpawnPin();
    }

    // Update is called once per frame
    void Update()
    {
        if (isGameOver) return;
        if (Input.GetMouseButtonDown(0))
        {
            score++;
            scoreText.text = score.ToString();
            currentPin.StartFly();
            SpawnPin();
        }
    }

    void SpawnPin()
    {
        currentPin = GameObject.Instantiate(pinPrefab, spawnPosition.position, pinPrefab.transform.rotation).GetComponent<Pin>();
    }

    public void GameOver()
    {
        if (isGameOver) return;

        GameObject.Find("Circle").GetComponent<RotateSelf>().enabled = false;
        
        isGameOver = true;
    }
}

游戏结束动画

当游戏结束后，将主摄像头背景变为红色，并且使摄像头size变小，使得游戏内容放大

通过camera组件进行控制
