**项目名称：Guess Card Game** **参考源码链接：** * 2D游戏引擎 Unity 示例代码 * 2D卡牌游戏脚本 **步骤：** **1. 创建场景及对象** * 创建一个新的场景。 * 在场景中创建一个新的 GameObject，将其设置为背景。 * 选择背景对象的 GameObject，并将其拖到场景中。 **2. 选择一张卡牌作为对象** * 在 Hierarchy窗口中，创建一个新 GameObject，将其设置为卡牌对象。 * 将卡牌对象拖到场景中的 Memory Card 下方。 * 修改卡牌对象的名称为 "Memory Card3"。 **3. 创建其他对象** * 创建一个空 GameObject，将其命名为 "Card Back"。 * 将卡背对象拖到 Memory Card 下方。 * 将卡背对象的子对象命名为 "Card Back"。 **4. 修改代码** * 创建一个名为 "MemoryCard.cs" 的新的 C# 文件。 * 在文件中添加以下代码： ```c# using UnityEngine; public class MemoryCard : MonoBehaviour { [SerializeField] private GameObject cardBack; public void OnMouseDown() { if (cardBack.activeSelf && controller.canReveal) { cardBack.SetActive(false); controller.CardRevealed(this); } } public void Unreveal() { cardBack.SetActive(true); } // 其他方法省略 } ``` **5. 创建脚本** * 创建一个名为 "SceneController.cs" 的新的 C# 文件。 * 在文件中添加以下代码： ```c# using UnityEngine; public class SceneController : MonoBehaviour { public const int gridRows = 2; public const int gridCols = 4; public const float offsetX = 2; public const float offsetY = 2.5f; private MemoryCard _firstRevealed; private MemoryCard _secondRevealed; private int _score = 0; public bool canReveal { get { return _secondRevealed == null; } } [SerializeField] private MemoryCard originalCard; [SerializeField] private Sprite[] images; [SerializeField] private TextMesh scoreLabel; public void CardRevealed(MemoryCard card) { if (_firstRevealed == null) { _firstRevealed = card; } else { _secondRevealed = card; StartCoroutine(CheckMatch()); } } private IEnumerator CheckMatch() { if (_firstRevealed.id == _secondRevealed.id) { _score++; Debug.Log("Score:\" + _score); } else { yield return new WaitForSeconds(.5f); _firstRevealed.Unreveal(); _secondRevealed.Unreveal(); } _firstRevealed = null; _secondRevealed = null; } // 其他方法省略 } ``` **6. 配置游戏** * 在 Unity 编辑器中，在 Inspector 面板中设置游戏变量。 * 在 "Memory Card" 中设置卡牌的初始位置。 * 在 "SceneController" 中设置背景图片和卡牌数量。 **7. 运行游戏** * 启动游戏，即可体验游戏。

效果图预览

step1: 创建一个3D项目

step2: 修改2D相关设置

点击Edit/Project Settings 再选择Editor选项修改Default Behaviour Mode的Mode为2D

修改选项卡为2D模式

step3: 准备工作

创建需要的文件夹

记住场景名字

在Sprites文件夹下准备相应的图片

卡牌图案： 150*200px

卡背：能盖住卡牌即可

重置按钮：无要求

背景：无要求

step4: 相关代码
