2D小游戏--猜对应卡牌(unity)

项目名称 guess_card_game

参考源码链接：https://www.manning.com/books/unity-in-action

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

MemoryCard.cs

using System.Collections;using System.Collections.Generic;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);     }    [SerializeField] private SceneController controller;    private int _id;    public int id    {        get { return _id; }    }    public void SetCard(int id, Sprite image)    {        _id = id;        GetComponent().sprite = image;    }    // Start is called before the first frame update    void Start()    {    }    // Update is called once per frame    void Update()    {    }}

SceneController.cs

using System.Collections;using System.Collections.Generic;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;    }    // Start is called before the first frame update    void Start()    {        Vector3 startPos = originalCard.transform.position;        int[] numbers = {0, 0, 1, 1, 2, 2, 3, 3 };        numbers = ShuffleArray(numbers);        for (int i = 0; i < gridCols; i++) {            for (int j = 0; j < gridRows; j++) {                MemoryCard card;                if (i == 0 && j == 0)                {                    card = originalCard;                }                else {                    card = Instantiate(originalCard) as MemoryCard;                }                int index = j * gridCols + i;                int id = numbers[index];                card.SetCard(id, images[id]);                                float posX = (offsetX * i) + startPos.x;                float posY = - (offsetY * j) + startPos.y;                card.transform.position = new Vector3(posX,posY,startPos.z);            }        }            }    private int[] ShuffleArray(int[] numbers) {        int[] newArray = numbers.Clone() as int[];        for (int i = 0; i < newArray.Length; i++) {            int tmp = newArray[i];            int r = Random.Range(i,newArray.Length);            newArray[i] = newArray[r];            newArray[r] = tmp;        }        return newArray;    }    // Update is called once per frame    void Update()    {            }}

UIButton.cs

using System.Collections;using System.Collections.Generic;using UnityEngine;public class UIButton : MonoBehaviour{    [SerializeField] private GameObject targetObject;    [SerializeField] private string targetMessage;    public Color highlightColor = Color.cyan;    public void OnMouseEnter()    {        SpriteRenderer sprite = GetComponent();        if (sprite != null)        {            sprite.color = highlightColor;        }    }    public void OnMouseExit()    {        SpriteRenderer sprite = GetComponent();        if (sprite != null)        {            sprite.color = Color.white;        }    }    public void OnMouseDown()    {        transform.localScale = new Vector3(1.1f, 1.1f, 1.1f);    }    public void OnMouseUp()    {        transform.localScale = Vector3.one;        if (targetObject != null)        {            targetObject.SendMessage(targetMessage);        }    }    // Start is called before the first frame update    void Start()    {            }    // Update is called once per frame    void Update()    {            }}

step5: 创建场景及对象

1、将背景从Project中拖到场景中

2、选择一张卡牌作为对象，拖到Hierarchy窗口，并修改名称为 Memory Card

3、将卡背拖到Memory Card下方作为子对象

4、创建空对象，依次修改名称

5、脚本挂载

Memory Card

card_back

Controller

Score

start-button
