C#从零开始学习(用户界面)(unity Lab4)

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

publicvoidClickOnBall(){
        Score++;}

在OneBallBehaviour类添加下列方法

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

GameController

usingSystem.Collections;usingSystem.Collections.Generic;usingUnityEngine;usingUnityEngine.UI;publicclassGameController:MonoBehaviour{publicGameObject OneBallPrefab;publicint Score =0;publicbool GameOver =true;publicint numberOfBalls =0;publicint MaximumBalls =15;publicText ScoreText;publicButton PlayAgainButton;// Start is called before the first frame updatevoidStart(){InvokeRepeating("AddBall",1.5F,1);}publicvoidClickOnBall(){
        Score++;
        numberOfBalls--;}// Update is called once per framevoidUpdate(){
        ScoreText.text = Score.ToString();}voidAddBall(){if(!GameOver){Instantiate(OneBallPrefab);
            numberOfBalls++;if(numberOfBalls >= MaximumBalls){
                GameOver =true;
                PlayAgainButton.gameObject.SetActive(true);}}}publicvoidStartGame(){foreach(GameObject ball in GameObject.FindGameObjectsWithTag("GameController")){Destroy(ball);}
        PlayAgainButton.gameObject.SetActive(false);
        Score =0;
        numberOfBalls =0;
        GameOver =false;}}
