推箱子简单实现（objective-c）

推箱子大家都知道吧，在cocos2d上简单实现了一个！

typedef enum
{
    None=-1,
    Wall=0,
    Worker,
    Box,
    Passageway,
    Destination,
    WorkerInDest,
    RedBox,
} Map_State;
//代表堆栈长度
#define MaxNum 300

这个枚举很重要， Wall：墙， Worke：工人，Box：箱子，Passageway：通道，Destination：目的地，WorkerInDest：工人在目的地，RedBox：箱子在目的地，游戏中会根据这些不同的类型，生成对应的精灵贴图，也就是说至少有7张图，我这里用Num1.png、Num2.png...Num7.png七张图来表示。游戏开始前我会有一个关卡的配置的plist，里面是一个一维数组：010101234567... 通过这个就可以进行初始化布局！

游戏初始化：

//游戏进入函数
-(void) show
{
    CGSize size = [[CCDirector sharedDirector] winSize];
    movableSprites = [[NSMutableArray alloc] init];
    
    labelStep = [CCLabelBMFont labelWithString:@"0" fntFile:@"mine.fnt"];
    labelStep.position =  ccp( size.width -30 , size.height-15 );
    [self addChild:labelStep];
    
    //后退按钮
	flagBt=[CCSprite spriteWithSpriteFrameName:@"btnFlaged.png"];
	flagBt.position=ccp(40,70);
	[self addChild:flagBt z:1 tag:1000];
	[movableSprites addObject:flagBt];
    
	//向上按钮
	upBt=[CCSprite spriteWithSpriteFrameName:@"up.png"];
	upBt.position=ccp(230,90);
	[self addChild:upBt z:1 tag:1001];
	[movableSprites addObject:upBt];
    
	//向下按钮
    downBt=[CCSprite spriteWithSpriteFrameName:@"down.png"];
	downBt.position=ccp(230,30);
	[self addChild:downBt z:1 tag:1002];
	[movableSprites addObject:downBt];
    
	//向左按钮
    leftBt=[CCSprite spriteWithSpriteFrameName:@"left.png"];
	leftBt.position=ccp(180,60);
	[self addChild:leftBt z:1 tag:1003];
	[movableSprites addObject:leftBt];
    
	//向右按钮
    rightBt=[CCSprite spriteWithSpriteFrameName:@"right.png"];
	rightBt.position=ccp(280,60);
	[self addChild:rightBt z:1 tag:1004];
	[movableSprites addObject:rightBt];
    
	//初始化
    [self intiGameConfig];
}

//游戏初始化
-(void) intiGameConfig
{
    W=30;//每个方块宽度
    m_col=10;//方块矩阵列数
    m_row=10;//方块矩阵行数
    m_count=m_row*m_col;//方块矩阵方块总数
    
    //栈顶
    s_top=-1;
    stackStep=(int *)malloc(sizeof(int)*MaxNum);//保存走过的方向，1上2下3左4右
    boxStatus=(int *)malloc(sizeof(int)*MaxNum);//保存行走时是否推了箱子
    
	//初始化二维数组
    myArrays=(int **)malloc(sizeof(int)*10);
    for (int i=0; i<10; i++) {
        myArrays[i]=(int *)malloc(sizeof(int)*10);
    }
    
	//读取关卡配置，一维数组：01010123456...
    NSString* plistPath = [[NSBundle mainBundle] pathForResource:@"level3" ofType:@"plist"];
    NSArray *Positions = [NSArray arrayWithContentsOfFile:plistPath];
    
    int tx=0;
    int ty=0;
    int type=-1;
    for (int i=0; i<m_count; i++) {
        tx=i/m_col;//行
        ty=i%m_col;//列
        type=[[Positions objectAtIndex:i] intValue];
        myArrays[tx][ty]=type;//保存方块类型
        
		//方块精灵
        CCSprite *p=[CCSprite spriteWithSpriteFrameName:[NSString stringWithFormat:@"Num%i.png",type]];
        p.tag=i;
        //p.anchorPoint=ccp(0, 0);
        p.position=ccp(10+15+ty*W,130+15+tx*W);
        [movableSprites addObject:p];
        [self addChild:p z:1];
        
        //找着工人位置
        if (type==Worker) {
            x=tx;
            y=ty;
            //tag=i=x*m_col+y;
        }
    }
    
}

工人行走功能实现：

-(void) ccTouchEnded:(UITouch*)touch withEvent:(UIEvent *)event
{
    CGPoint touchlocation = [touch locationInView: [touch view]];
    touchlocation =[[CCDirector sharedDirector] convertToGL:touchlocation];
    
    CCSprite * newSprite = nil;
	if (newSprite == nil) {
		for (CCSprite *sprite in movableSprites) {
			if (CGRectContainsPoint(sprite.boundingBox, touchlocation)) {            
				newSprite = sprite;
				break;
			}
		} 
		
	}
    if (newSprite==nil) {
        CCLOG(@"NO CCSprite has beend touched!");
    }
    else
    {
        int x_1;
        int y_1;
        int x_2;
        int y_2;
        
        int na = [newSprite tag];
        //CCLOG(@"tounchTag:%i",na);
        switch (na) {
            case 1000:
                CCLOG(@"后退");
                //
                [self GoBack];
                break;
            case 1001:

                [self MoveTo:1 x1:x_1 y1:y_1 x2:x_2 y2:y_2];
                break;
            case 1002:
                CCLOG(@"下");
                x_1=x-1;

好了，就这么多，回头我会再贴一个，C#写的地图编辑器！欢迎交流！
