这是书本中第四个unity Lab

在这次实验中,将学习如何搭建一个开始界面

分数系统

点击球,会增加分数

csharp 复制代码

    public void ClickOnBall()
    {
        Score++;
    }

在OneBallBehaviour类添加下列方法

csharp 复制代码

    void OnMouseDown()
    {
        GameController controller = Camera.main.GetComponent<GameController>();
        controller.ClickOnBall();
        Destroy(gameObject);
    }

GameController

csharp 复制代码

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

public class GameController : MonoBehaviour
{
    public GameObject OneBallPrefab;
    public int Score = 0;
    public bool GameOver = true;

    public int numberOfBalls = 0;
    public int MaximumBalls = 15;

    public Text ScoreText;
    public Button PlayAgainButton;
    // Start is called before the first frame update
    void Start()
    {
        InvokeRepeating("AddBall", 1.5F, 1);
    }
    public void ClickOnBall()
    {
        Score++;
        numberOfBalls--;
    }
    // Update is called once per frame
    void Update()
    {
        ScoreText.text = Score.ToString();
    }
    void AddBall()
    {
        if (!GameOver)
        {
            Instantiate(OneBallPrefab);
            numberOfBalls++;
            if (numberOfBalls >= MaximumBalls)
            {
                GameOver = true;
                PlayAgainButton.gameObject.SetActive(true);
            }
        }

    }
    public void StartGame()
    {
        foreach (GameObject ball in GameObject.FindGameObjectsWithTag("GameController"))
        {
            Destroy(ball);
        }
        PlayAgainButton.gameObject.SetActive(false);
        Score = 0;
        numberOfBalls = 0;
        GameOver = false;
    }
}

给游戏增加界面

增加界面

在UI中显示分数

点击Hierarchy中的text,在inspector窗口下修改

增加按钮调用

设置好后,将这些绑定
