Unity3D消消乐实现原理
基本原理:
遍历所有宝石集合,判断行和列三连的情况,删除三连,更新上方宝石位置.
1.定义一个宝石脚本,功能:随机指定宝石类型,指定宝石位置,iTween动画,销毁,颜色
using UnityEngine;
using System.Collections;
public class Gemstone : MonoBehaviour {
public float xOffset = -4.0f; //x方向的偏移
public float yOffset = -1.5f; //y方向的偏移
public int rowIndex = 0; //行号
public int columnIndex = 0; //列号
public GameObject[] gemstoneBgs; //宝石(gemstone)的数组
public int gemstoneType; //宝石(gemstone)的类型
public GameController gameController;
public SpriteRenderer spriteRenderer;
public bool isSelected{
set{
if(value){
spriteRenderer.color = Color.red;
}else{
spriteRenderer.color = Color.white;
}
}
}
private GameObject gemstoneBg;
// Use this for initialization
void Awake(){
}
void Start () {
gameController = GameObject.Find ("GameController").GetComponent ();
spriteRenderer = gemstoneBg.GetComponent ();
}
// Update is called once per frame
void Update () {
}
public void UpdatePosition(int _rowIndex,int _columnIndex){ //调整gemstone(宝石）的位置
rowIndex = _rowIndex;
columnIndex = _columnIndex;
this.transform.position = new Vector3 (columnIndex*1.2f + xOffset, rowIndex*1.2f + yOffset, 0);
}
public void TweenToPostion(int _rowIndex,int _columnIndex){
rowIndex = _rowIndex;
columnIndex = _columnIndex;
iTween.MoveTo (this.gameObject, iTween.Hash ("x",columnIndex * 1.2f + xOffset,"y",rowIndex*1.2f + yOffset,"time",0.3f));
}
public void RandomCreateGemstoneBg(){ //生成随机的宝石类型
if (gemstoneBg != null)
return;
gemstoneType = Random.Range (0, gemstoneBgs.Length);
gemstoneBg = Instantiate(gemstoneBgs[gemstoneType]) as GameObject;
gemstoneBg.transform.parent = this.transform;
}
//鼠标点击的回调方法
public void OnMouseDown(){
gameController.Select (this);
}
public void Dispose(){
Destroy (this.gameObject);
Destroy (gemstoneBg.gameObject);
gameController = null;
}
}
将所有的宝石预制体拖到集合目录下
2.定义管理脚本
声明一下字段:
Start里面初始化;
定义如下方法:
///
/// 生成宝石的方法
///
/// 返回一个定义好的宝石.
/// Row 行坐标.
/// Column 列坐标.
public Gemstone AddGemstone(int rowIndex,int columnIndex){ //生成宝石
//克隆一个宝石
Gemstone c = Instantiate (gemstone) as Gemstone;
c.transform.parent = this.transform;//指定父物体
c.GetComponent().RandomCreateGemstoneBg();//调用宝石本身上宝石脚本的随机指定宝石类型的方法
c.GetComponent().UpdatePosition (rowIndex,columnIndex);//调用借用行号和列号自动排列(指定位置)的方法
return c;
}
///
/// 查找行号和列好对应宝石的方法
///
/// The gemstone.
/// Row index.
/// Column index.
public Gemstone GetGemstone(int rowIndex,int columnIndex){ //通过行号和列号，取得所对应位置的宝石
ArrayList temp = gemstoneList [rowIndex] as ArrayList;
Gemstone c = temp [columnIndex] as Gemstone;
return c;
}
public void SetGemstone(int rowIndex,int columnIndex, Gemstone c){ //设置所对应列号和列号位置的宝石
ArrayList temp = gemstoneList [rowIndex] as ArrayList;
temp [columnIndex] = c;
}
//点选当前宝石的时候,指定当前宝石的color,如果当前宝石为空时,表示是第一次点选,那么颜色指定为红色,如果不为空的话,表示是第二点选(即交换的对象)
public void Select(Gemstone c){
//Destroy (c.gameObject); //测试，让所点击的物体消失
if (currentGemstone == null) {
currentGemstone = c;
currentGemstone.isSelected = true;
return;
}else{
if( Mathf.Abs(currentGemstone.rowIndex - c.rowIndex) + Mathf.Abs(currentGemstone.columnIndex - c.columnIndex) == 1 ){//判断是否挨着的
StartCoroutine (ExangeAndMatches(currentGemstone,c));//开启协程,实现宝石交换并且检测是否匹配
}else{
GetComponent().PlayOneShot(errorClip);
}
currentGemstone.isSelected = false;
currentGemstone = null;
}
}
IEnumerator ExangeAndMatches(Gemstone c1,Gemstone c2){ //实现宝石交换并且检测是否匹配
Exchange(c1,c2);//调用交换宝石的方法
yield return new WaitForSeconds (0.5f);//等待0.5s
if(CheckHorizontalMatches() || CheckVerticalMatches() ){//经过水平检测和垂直检测后,如若有成功匹配的
RemoveMatches();//执行删除宝石的方法
}
else{//如果没有匹配的宝石,直接在交换回来
// Debug.Log ("没有检测到相同的宝石，交换回来！！");
Exchange(c1,c2);
}
}
///
/// 水平检测的方法,返回一个布尔值
///
/// true , if horizontal matches was checked, false otherwise.
/// 垂直检测的方法,同事也会返回一个布尔值
///
/// true , if vertical matches was checked, false otherwise.
/// 删除三联的宝石
///
void RemoveMatches(){ //删除匹配的宝石
for(int i=0; i< matchesGemstone.Count; i++){//遍历三联的列表
Gemstone c = matchesGemstone[i] as Gemstone;
RemoveGemstone(c);//调用删除宝石的方法
}
matchesGemstone = new ArrayList ();//重新更新三联列表
StartCoroutine (WaitForCheckMatchesAgain ());//开启携程,检测是否还有因为销毁三联宝石以后还有自动匹配的三联宝石,如果有直接销毁
}
IEnumerator WaitForCheckMatchesAgain(){
yield return new WaitForSeconds (0.5f);
if (CheckHorizontalMatches () || CheckVerticalMatches ()) {
RemoveMatches ();
}
}
void RemoveGemstone(Gemstone c){ //删除宝石
//Debug.Log ("删除宝石！");
c.Dispose ();
GetComponent().PlayOneShot (match3Clip);
for (int i=c.rowIndex +1; i
/// 交换宝石的方法
///
/// C1.
/// C2.
public void Exchange(Gemstone c1,Gemstone c2){ //实现宝石之间交换位置
GetComponent().PlayOneShot (swapClip); //播放交换的声音
SetGemstone (c1.rowIndex, c1.columnIndex, c2);
SetGemstone (c2.rowIndex, c2.columnIndex, c1);
//交换c1,c2的行号
int tempRowIndex;
tempRowIndex = c1.rowIndex;
c1.rowIndex = c2.rowIndex;
c2.rowIndex = tempRowIndex;
//交换c1,c2的列号
int tempColumnIndex;
tempColumnIndex = c1.columnIndex;
c1.columnIndex = c2.columnIndex;
c2.columnIndex = tempColumnIndex;
//c1.UpdatePosition (c1.rowIndex, c1.columnIndex);
//c2.UpdatePosition (c2.rowIndex, c2.columnIndex);
//ITween动画将两个宝石移动到指定的行号和列号的位置上
c1.TweenToPostion (c1.rowIndex, c1.columnIndex);
c2.TweenToPostion (c2.rowIndex, c2.columnIndex);
}
