Unity3d开发“类三消”游戏

新建一个Project，导入图片素材和声音文件，把图片的Texture Type都修改为Sprite(2D and UI)【1】。新建一个命名为Background的GameObject，为之添加背景素材图片【2】。再新建一个命名为GameController的GameObject，为之添加GameController脚本和AudioSource组件。把消除素材图片都做成预设体(Prefabs)【3】，顺便再Copy多一个预设体，重命名为Gemstone，把Sprite设为空(None)，为之添加Gemstone脚本和BoxCollider组件。

    【1】                                             【3】

为GameController添加声音源文件和Gemstone脚本

Gemstone.cs脚本

using System.Collections;  
  
public class Gemstone : MonoBehaviour {  
  
    public float xOffset = -4.5f;//x方向的偏移  
    public float yOffset = -2.0f;//y方向的偏移  
    public int rowIndex = 0;  
    public int columIndex = 0;  
    public GameObject[] gemstoneBgs;//宝石数组  
    public int gemstoneType;//宝石类型  
    private GameObject gemstoneBg;  
    private GameController gameController;  
    private SpriteRenderer spriteRenderer;  
    public bool isSelected{  
        set{  
            if(value){  
                spriteRenderer.color=Color.red;  
            }else{  
                spriteRenderer.color=Color.white;  
            }  
        }  
    }  
    // Use this for initialization  
    void Start () {  
        gameController = GameObject.Find ("GameController").GetComponent<GameController> ();  
        spriteRenderer = gemstoneBg.GetComponent<SpriteRenderer> ();  
    }  
      
    // Update is called once per frame  
    void Update () {  
      
    }  
    public void UpdatePosition(int _rowIndex,int _columIndex){//宝石的位置  
        rowIndex = _rowIndex;  
        columIndex = _columIndex;  
        this.transform.position = new Vector3 (columIndex + xOffset, rowIndex + yOffset, 0);  
    }  
    public void TweenToPostion(int _rowIndex,int _columIndex){//调用iTween插件实现宝石滑动效果  
        rowIndex = _rowIndex;  
        columIndex = _columIndex;  
        iTween.MoveTo (this.gameObject, iTween.Hash ("x", columIndex + xOffset, "y", rowIndex + yOffset, "time", 0.5f));  
    }  
    public void RandomCreateGemstoneBg(){//随机的宝石类型  
        if (gemstoneBg != null)   
            return;  
        gemstoneType = Random.Range (0, gemstoneBgs.Length);  
        gemstoneBg = Instantiate (gemstoneBgs [gemstoneType])as GameObject;  
        gemstoneBg.transform.parent = this.transform;  
    }  
    public void OnMouseDown(){  
        gameController.Select (this);  
    }  
    public void Dispose(){  
        Destroy (this.gameObject);  
        Destroy (gemstoneBg.gameObject);  
        gameController = null;  
    }  

为Gemstone预设体添加消除素材图片

最后在MainCamera添加AudioSource组件来播放背景音乐

运行效果
