STEP 1

重新調整遊戲首頁的腳本控制

開啟 SuperNewJeans-Home 場景，並建立一個名為 HomeManager 的腳本

➔ 開啟 HomeManager 腳本，輸入以下程式碼並存檔

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

public class HomeManager : MonoBehaviour
{
    void Start()
    {

    }

    void Update()
    {

    }

    public void GameStart()
    {
        SceneManager.LoadScene("SuperNewJeans");
    }
}

➔ 回到 Unity 介面，點擊 Game Manager 物件，並關閉 GameManager 腳本

➔ 將 HomeManager 腳本 拖曳至 Game Manager 物件中

➔ 將 Start 按鈕在 OnClick 欄位的腳本修改為 HomeManager.GameStart 的方式

HomeManager 腳本主要是用於控制 SuperNewJeans-Home 場景的操作

可以選擇關閉或刪除 GameManager 物件中的 GameManager 腳本

STEP 2

修改 Player 撞擊障礙物時的效果樣式

開啟 SuperNewJeans 場景 ➔ 開啟 PlayerController 腳本，將程式碼修改為以下版本並存檔

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using DG.Tweening;

public class PlayerController : MonoBehaviour
{
		public GameManager gm;
		public float currentPosY = 0;
		public float speed = 0;
		
		void Start()
		{
				gm = GameObject.Find("GameManager").GetComponent<GameManager>();
				currentPosY = 0.75f;
				speed = 0.1f;
		}
		
		void Update()
		{
			
		}
		
		private void FixedUpdate()
		{
				if (Input.GetKey(KeyCode.UpArrow) || Input.GetKey(KeyCode.W))
				{
						currentPosY = currentPosY + speed;
		
						if (currentPosY >= 5.3f)
						{
								currentPosY = 5.3f;
						}
				}
	
		    if (Input.GetKey(KeyCode.DownArrow) || Input.GetKey(KeyCode.S))
		    {
						currentPosY = currentPosY - speed;
		
						if (currentPosY <= -3.3f)
						{
								currentPosY = -3.3f;
						}
		    }
		        gameObject.transform.position = new Vector3(-5.5f, currentPosY, 0f);
		}
		
		private void OnTriggerEnter(Collider collision)
		{
				string type = collision.gameObject.tag;
				GameObject targetObject = collision.gameObject;
		
				if (type == "rabbit")
		    {
				    Debug.Log("hit rabbit");
						gm.updateRabbitPoint();
						Destroy(targetObject);
		    }
		
				if (type == "cookie")
		    {
				    Debug.Log("hit cookie");
						gm.updateCookiePower();
						Destroy(targetObject);
		    }
		
				if (type == "big-rabbit")
		    {
				    Debug.Log("hit big-rabbit");
		    }
		
		
				// 會扣HP的種類
				
				if (type == "floor")
		    {
				    Debug.Log("hit floor");
						if (isInvincible) return; // 如果是無敵狀態，則不執行以下程式碼
						gm.updateHP(-1);
						damageEffect();
		    }
		
				if (type == "enemy")
		    {
				    Debug.Log("hit enemy");
						if (isInvincible) return; // 如果是無敵狀態，則不執行以下程式碼
						gm.updateHP(-1);
						damageEffect();
		    }
		}
		
		void damageEffect()
    {
        if (isInvincible == false)
        {
            isInvincible = true;
            hidePlayer();
            Invoke("initDamageEffect", 1.2f);
        }
    }

    bool isInvincible = false;
    int hideCounter = 0;
    int hideTimes = 6;

    void hidePlayer()
    {
        if (hideCounter < hideTimes)
        {
            hideCounter++;
            transform.GetChild(0).gameObject.SetActive(false);
            Invoke("showPlayer", 0.1f);
        }
    }

    void showPlayer()
    {
        transform.GetChild(0).gameObject.SetActive(true);
        Invoke("hidePlayer", 0.1f);
    }

    void initDamageEffect()
    {
        isInvincible = false;
        hideCounter = 0;
    }
}

STEP 3

完成各階段 UI 畫面與流程

開啟 GameManager 腳本，將程式碼修改為以下版本並存檔

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

public class GameManager : MonoBehaviour
{
		public GameObject player;
		public int score = 0;
		public float score_f = 0;
		public int hp = 3;
		public int cookiePower = 0;
		public int highScore = 0;
		public int rabbitPoint = 0;
		public bool isGameOver = false; // 新增遊戲結束的布林值變數
		public List<GameObject> steps = new List<GameObject>();
		
		// UI
		public TextMeshProUGUI hpUI;
		public TextMeshProUGUI rabbitUI;
		public TextMeshProUGUI scoreUI;
		public TextMeshProUGUI cookieUI;
		public TextMeshProUGUI gameOverScoreUI;

		void Start()
		{
				score = 0;
				hp = 3;
				cookiePower = 0;
		}
		
		void Update()
		{
				// 設定Score的計算方式
				if(isGameOver == false)
				{
						score_f = score_f + Time.deltaTime;
						score = Mathf.RoundToInt(score_f);
				}

				// 設定UI畫面中各項數值與文字的變化
				hpUI.text = " HP: " + hp;
				rabbitUI.text = " rabbits: " + rabbitPoint;
				scoreUI.text = " Score: " + score;
				gameOverScoreUI.text = scoreUI.text;
				cookieUI.text = " cookie power: " + cookiePower;
		}
		
		public void updateHP(int amount)
		{
				hp = hp + amount;

				if(hp >= 3)
				{
						hp = 3;
				}
		
				if(hp <= 0)
				{
						Debug.Log("遊戲結束");
						GameOver();
				}
		}
		
		public void updateCookiePower()
		{
				cookiePower = cookiePower + 10;
		}
		
		public void updateRabbitPoint()
		{
				rabbitPoint = rabbitPoint + 1;
		}
		
		public void ChangeStepUI(int step)
		{
				for (int i = 0; i < 3; i++)
				{
						steps[i].SetActive(false);
				}
		
				steps[step].SetActive(true);
		}
		
		public void GameStart()
		{
				SceneManager.LoadScene("SuperNewJeans");
		}
		
		public void Exit()
		{
				SceneManager.LoadScene("SuperNewJeans-Home");
		}
		
		public void GameOver()
		{
				// 遊戲結束
				isGameOver = true;

				// 判斷是否更新最高分
				int oldScore = PlayerPrefs.GetInt("highScore");
        int newScore = score;

        if (newScore > oldScore)
        {
            PlayerPrefs.SetInt("highScore", newScore);
        }

				// 切換UI畫面
				ChangeStepUI(2);
		}
		
		public void Restart()
		{
				SceneManager.LoadScene("SuperNewJeans-Home");
		}
}

➔ 回到 Unity 介面，在 Game Manager 物件 中會發現剛剛新增的 UI 變數欄位

➔ 將 EndScore 物件拖曳至 Game Over Score UI 的欄位中

STEP 4

回到首頁完成最高分設定

➔ 開啟 SuperNewJeans-Home 場景 ➔ 開啟 HomeManager 腳本，將程式碼修改為以下版本並存檔

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

public class HomeManager : MonoBehaviour
{
		public TextMeshProUGUI highScoreUI;

    void Start()
    {
				highScoreUI.text = "HighScore:" + PlayerPrefs.GetInt("highScore");
    }

    void Update()
    {

    }

    public void GameStart()
    {
        SceneManager.LoadScene("SuperNewJeans");
    }
}

➔ 回到 Unity 介面，在 Game Manager 物件 中會發現剛剛新增的 UI 變數欄位

➔ 將 HighScore 物件拖曳至 High Score UI 的欄位中即可

當更新最高分紀錄後，便會自動更新首頁的 HighScore 數值
