Unity to realize the game

Time:2020-12-4

In this paper, we share the specific code of unity for the implementation of the game, for your reference, the specific content is as follows

Control the ball to rotate

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

public class RotateSelf : MonoBehaviour {
  //Rotate 90 degrees per second
  public float speed = 90;

  // Update is called once per frame
  void Update () {
   //Rotate clockwise about Z axis
    transform.Rotate(new Vector3(0, 0, -speed * Time.deltaTime));
  }
}

Probe collision detection


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

public class PinHead : MonoBehaviour {

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

Control the movement position of the needle


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

public class Pin : MonoBehaviour {

  public float speed = 5;
  private bool isFly = false;
  private bool isReach = false;
  private Transform startPoint;
  private Vector3 targetCirclePos;
  private Transform circle;

  // Use this for initialization
  void Start () {
    startPoint = GameObject.Find("StartPoint").transform;
    circle = GameObject.FindGameObjectWithTag("Circle").transform;
    targetCirclePos = circle.position;
    targetCirclePos.y -= 1.55f;
  }

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

Game management

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using UnityEngine.SceneManagement;

public class GameManager : MonoBehaviour {

  private Transform startPoint;
  private Transform spawnPoint;
  private Pin currentPin;
  private bool isGameOver = false;
  private int score = 0;
  private Camera mainCamera;
  public Text scoreText;
  public GameObject pinPrefab;
  public float speed = 3;

  // Use this for initialization
  void Start () {
    startPoint = GameObject.Find("StartPoint").transform;
    spawnPoint = GameObject.Find("SpawnPoint").transform;
    mainCamera = Camera.main;
    SpawnPin();
  }

  private void Update()
  {
    if (isGameOver) return;
    if (Input.GetMouseButtonDown(0))
    {
      score++;
      scoreText.text = score.ToString();
      currentPin.StartFly();
      SpawnPin();
    }
  }

  void SpawnPin()
  {
     //Instantiation of needle
    currentPin = GameObject.Instantiate(pinPrefab, spawnPoint.position, pinPrefab.transform.rotation).GetComponent<Pin>();
  }

  public void GameOver()
  {
    if (isGameOver) return;
    GameObject.Find("Circle").GetComponent<RotateSelf>().enabled = false;
    StartCoroutine(GameOverAnimation());
    isGameOver = true;
  }

  IEnumerator GameOverAnimation()
  {
    while (true)
    {
      mainCamera.backgroundColor = Color.Lerp(mainCamera.backgroundColor, Color.red, speed * Time.deltaTime);
      mainCamera.orthographicSize = Mathf.Lerp(mainCamera.orthographicSize, 4, speed * Time.deltaTime);
      if( Mathf.Abs( mainCamera.orthographicSize-4 )<0.01f)
      {
        break;
      }
      yield return 0;
    }
    yield return new WaitForSeconds(0.2f);
    //Reload scene
    SceneManager.LoadScene(SceneManager.GetActiveScene().buildIndex);
  }
}
