Unity3d開發“類三消”游戲

本文轉載自查看原文 2017-07-05 09:44 2872 算法/ Unity3D/ 三消算法

新建一個Project，導入圖片素材和聲音文件，把圖片的Texture Type都修改為Sprite(2D and UI)【1】。新建一個命名為Background的GameObject，為之添加背景素材圖片【2】。再新建一個命名為GameController的GameObject，為之添加GameController腳本和AudioSource組件。把消除素材圖片都做成預設體(Prefabs)【3】，順便再Copy多一個預設體，重命名為Gemstone，把Sprite設為空(None)，為之添加Gemstone腳本和BoxCollider組件。

為GameController添加聲音源文件和Gemstone腳本

Gemstone.cs腳本

 1 using System.Collections;  
 2   
 3 public class Gemstone : MonoBehaviour {  
 4   
 5     public float xOffset = -4.5f;//x方向的偏移  
 6     public float yOffset = -2.0f;//y方向的偏移

 8     public int columIndex = 0;  
 9     public GameObject[] gemstoneBgs;//寶石數組  
10     public int gemstoneType;//寶石類型  
11     private GameObject gemstoneBg;  
12     private GameController gameController;  
13     private SpriteRenderer spriteRenderer;  
14     public bool isSelected{  
15         set{  
16             if(value){

18             }else{  
19                 spriteRenderer.color=Color.white;  
20             }  
21         }  
22     }  
23     // Use this for initialization  
24     void Start () {  
25         gameController = GameObject.Find ("GameController").GetComponent<GameController> ();  
26         spriteRenderer = gemstoneBg.GetComponent<SpriteRenderer> ();  
27     }  
28       
29     // Update is called once per frame  
30     void Update () {  
31       
32     }  
33     public void UpdatePosition(int _rowIndex,int _columIndex){//寶石的位置  
34         rowIndex = _rowIndex;  
35         columIndex = _columIndex;  
36         this.transform.position = new Vector3 (columIndex + xOffset, rowIndex + yOffset, 0);  
37     }  
38     public void TweenToPostion(int _rowIndex,int _columIndex){//調用iTween插件實現寶石滑動效果  
39         rowIndex = _rowIndex;  
40         columIndex = _columIndex;  
41         iTween.MoveTo (this.gameObject, iTween.Hash ("x", columIndex + xOffset, "y", rowIndex + yOffset, "time", 0.5f));  
42     }  
43     public void RandomCreateGemstoneBg(){//隨機的寶石類型  
44         if (gemstoneBg != null)   
45             return;  
46         gemstoneType = Random.Range (0, gemstoneBgs.Length);  
47         gemstoneBg = Instantiate (gemstoneBgs [gemstoneType])as GameObject;  
48         gemstoneBg.transform.parent = this.transform;  
49     }  
50     public void OnMouseDown(){  
51         gameController.Select (this);  
52     }  
53     public void Dispose(){  
54         Destroy (this.gameObject);  
55         Destroy (gemstoneBg.gameObject);  
56         gameController = null;  
57     }

為Gemstone預設體添加消除素材圖片

最后在MainCamera添加AudioSource組件來播放背景音樂

運行效果
