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。

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 = ;
     public int columIndex = ;
     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, );
     }
     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 (, 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
