    昨天我们的勇士可以穿越楼层了，但是我们的游戏界面还不够“生动”，接下来我们就要

添加一些代码使其“生动”起来。

    这部分代码不多但是却能让地图上的怪物都动来，那么就让我们来添加一下这部分代

码吧，这部分代码需要添加到TitledMap.m中titledMapAnalytic方法中if(heroPoint_tileGid)

循环的下面如图：

if (enemy_tileGid)             {                NSDictionary *props = [self propertiesForGID:enemy_tileGid];                NSString *value = [props valueForKey:@"enemy"];                int type = [value intValue];                CCTexture2D *Texture = [[CCTextureCache sharedTextureCache] addImage:@"enemy.png"];                CCSpriteFrame *frame0 ,*frame1,*frame2,*frame3;                //第二个参数表示显示区域的x, y, width, height，根据type来确定显示的y坐标                frame0 = [CCSpriteFrame frameWithTexture:Texture rect:CGRectMake(32*0, type*32, 32, 32)];                frame1 = [CCSpriteFrame frameWithTexture:Texture rect:CGRectMake(32*1, type*32, 32, 32)];                frame2 = [CCSpriteFrame frameWithTexture:Texture rect:CGRectMake(32*2, type*32, 32, 32)];                frame3 = [CCSpriteFrame frameWithTexture:Texture rect:CGRectMake(32*3, type*32, 32, 32)];                NSMutableArray *animFrames = [NSMutableArray array];                [animFrames addObject:frame0];                [animFrames addObject:frame1];                [animFrames addObject:frame2];                [animFrames addObject:frame3];                //循环动画序列                CCAnimation *animation = [CCAnimation animationWithFrames:animFrames delay:0.2f];                CCAnimate *animate = [CCAnimate actionWithAnimation:animation];                CCSequence *seq = [CCSequence actions: animate,nil];                [[self.enemy tileAt:towerLoc]runAction:[CCRepeatForever actionWithAction: seq]];            }

这个跟之前的开门动画加载方式差不多我就不多讲了。运行一下游戏，你就会发现我们的怪物

动起来了，这样看着是不是更有感觉了!

下面让我们随着游戏一直来到三楼，直接到商店你会发现商店没有任何响应，接下来我们就要

开始添加商店的响应事件了，不过在这之前我们要先把我们的商店界面设计好。代码：

ShopLayer.h文件内容

#import 
    
     #import "cocos2d.h"@interface ShopLayer : CCLayer{    CCLabelTTF *introduction;    CCLabelTTF *addHP;    CCLabelTTF *addAttack;    CCLabelTTF *addDefense;    CCLabelTTF *exitShop;    CCLabelTTF *enter;}@property (nonatomic,assign)int curHP;@property (nonatomic,assign)int curAttack;@property (nonatomic,assign)int curDefense;@property (nonatomic,assign)int curCoin;//当前选中商店编号@property (nonatomic,assign) int selID;//是否在购买状态@property (nonatomic,assign) int isOnShop;@property (nonatomic,retain) CCSprite *selSprite; -(id)initWithID:(int) shopID;@end
    

ShopLayer.m文件内容

#import "ShopLayer.h"#import "Hero.h"#import "Herohp.h"@implementation ShopLayer@synthesize curHP;@synthesize curCoin;@synthesize curAttack;@synthesize curDefense;@synthesize selSprite;@synthesize isOnShop;@synthesize selID;-(void)viewInit{    //获取屏幕大小    CGSize size = [[CCDirector sharedDirector] winSize];    self.selSprite = [CCSprite spriteWithFile:@"logo_select.png"];    self.selSprite.scaleX = 2.0;    id blink = [CCBlink actionWithDuration:2 blinks:2];    [self.selSprite runAction:[CCRepeatForever actionWithAction:blink]];    self.selID = 0;    //背景    CCTMXTiledMap *background = [CCTMXTiledMap tiledMapWithTMXFile:@"shopbg.tmx"];    background.scale = 2.0;    background.position = ccp(40, size.height / 2 - 200);    [self addChild:background];    //介绍标签    introduction = [[CCLabelTTF alloc] initWithString:[NSString stringWithFormat:@"勇士你好，这里是商店你花%d金币即可选择一下任意一项",self.curCoin] dimensions:CGSizeMake(500, 100) alignment:UITextAlignmentCenter fontName:@"Verdana-Bold" fontSize:32];    introduction.position = ccp(350, size.height - 165);    [self addChild:introduction];    //加血标签    addHP = [[CCLabelTTF alloc] initWithString:[NSString stringWithFormat:@"增加%d血量",self.curHP] fontName:@"Verdana-Bold" fontSize:30];    addHP.position = ccp(350, size.height - 260);    [self addChild:addHP];    //加攻标签    addAttack = [[CCLabelTTF alloc] initWithString:[NSString stringWithFormat:@"增加%d攻击",self.curAttack] fontName:@"Verdana-Bold" fontSize:30];    addAttack.position = ccp(350, size.height - 320);    [self addChild:addAttack];    //加防标签    addDefense = [[CCLabelTTF alloc] initWithString:[NSString stringWithFormat:@"增加%d防御",self.curDefense] fontName:@"Verdana-Bold" fontSize:30];    addDefense.position = ccp(350, size.height - 380);    [self addChild:addDefense];    //离开商店    exitShop = [[CCLabelTTF alloc] initWithString:@"离开商店" fontName:@"Verdana-Bold" fontSize:30];    exitShop.position = ccp(350, size.height - 440);    [self addChild:exitShop];    //确定    enter = [[CCLabelTTF alloc] initWithString:@"确定" fontName:@"Verdana-Bold" fontSize:30];    enter.position = ccp(350,size.height - 500);    [self addChild:enter];    [self addChild:self.selSprite];    self.selSprite.position = addHP.position;}-(id)initWithID:(int) shopID{    if ((self = [super init]))     {        if (shopID == 1)         {            self.curCoin = 25;            self.curAttack = 4;            self.curDefense = 4;            self.curHP = 800;        }        else        {            self.curCoin = 100;            self.curAttack = 20;            self.curDefense = 20;            self.curHP = 4000;        }        [self viewInit];    }    return self;}@end

这部分代码我就不多讲了，下面我们就开始添加Game01.m中调用部分和操作控制

首先我们要在if(other_tileGid)方法中添加以下代码：

NSDictionary *props = [self.curtitleMap propertiesForGID:other_tileGid];NSString *value = [props valueForKey:@"shop"];int type = [value intValue];if (type) {   _hero.isFighting = YES;   shop = [[ShopLayer alloc] initWithID:type];   shop.isOnShop = YES;   [self addChild:shop];}

当我们在购买状态时是不能进行除了商店以外的操作的，所以我把勇士的战斗状态赋值为YES

在我们这个游戏中是有两个商店的，所以我们在初始化商店的时候通过商店编号来识别。

到这里我们的商店界面出现了，下面就要开始添加商店操作了，这部分代码需要添加到

Game01.m文件的触摸响应事件中去

if (shop.isOnShop)     {        for (int i = 0; i <= 4; i++)         {            CGRect Rect1 = CGRectMake(200,                                      size.height - 290 - i*60,                                      400,                                      60);            //检测触点是否在控件区            if (CGRectIntersectsRect(Rect, Rect1))            {                if (i == 4)                 {                    if (herohp.Coin >= shop.curCoin)                     {                        switch (shop.selID)                        {                            case 0:                                _hero.HP += shop.curHP;                                [herohp updateHeroHp];                                break;                            case 1:                                _hero.Attack += shop.curAttack;                                [herohp updateHeroAttack];                                break;                            case 2:                                _hero.Defense += shop.curDefense;                                [herohp updateHeroDefense];                                break;                            default:                                break;                        }                        herohp.Coin -= shop.curCoin;                        [herohp updateCoin];                    }                }                else if (i == 3)                 {                    _hero.isFighting = NO;                    shop.isOnShop = NO;                    [self removeChild:shop cleanup:YES];                }                else                    shop.selID = i;                if (i<3)                 {                    shop.selSprite.position = ccp(350, size.height - 260 - i*60);                }            }        }    }

终于我们的商店可以使用了，但是一个问题来了我们没有金币啊，金币是打怪的时候得到的

那么我们就要在消除怪物的时候更新一下金币和经验了代码如下：

canmove = YES;    herohp.Coin += self.selenemy.Coin;    herohp.Experience += self.selenemy.Experience;    [herohp updateCoin];    [herohp updateExperience];

这样我们就能够获得金币和经验了，不过为了测试方便，这里我们可以修改一些参数，

self.HP = 10000;        self.Attack = 1000;        self.Defense = 1000;

金币和经验也可以适当修改，修改过之后，让我们再次随着勇士的脚步来到5楼吧，这里

你会看到两个npc,地图左边的是神秘老人，右边的是商人，神秘老人是可以说是经验商店

在这里你可以用经验提升勇士的能力；商人是卖钥匙的，在这里你可以买到各种钥匙。

讲到这里我们又需要添加两个类Business和Buykey跟商店差不多这里我就不多讲了，直接

上代码：

Business.h代码：

#import 
    
     #import "cocos2d.h"@interface Business : CCLayer {    CCLabelTTF *introduction;    CCLabelTTF *addGrade;    CCLabelTTF *addAttack;    CCLabelTTF *addDefense;    CCLabelTTF *exitShop;    CCLabelTTF *enter;}@property (nonatomic,assign)int curUpgrade;@property (nonatomic,assign)int curAttack;@property (nonatomic,assign)int curDefense;@property (nonatomic,assign)int curExperience;@property (nonatomic,assign)int curExperience2;//当前选中商店编号@property (nonatomic,assign) int selID;//是否在购买状态@property (nonatomic,assign) int isOnShop;@property (nonatomic,retain) CCSprite *selSprite; -(id)initWithID:(int) shopID;@end
    

Business.m代码：

#import "Business.h"@implementation Business@synthesize curUpgrade;@synthesize curExperience;@synthesize curExperience2;@synthesize curAttack;@synthesize curDefense;@synthesize selSprite;@synthesize isOnShop;@synthesize selID;-(void)viewInit{    //获取屏幕大小    CGSize size = [[CCDirector sharedDirector] winSize];    self.selSprite = [CCSprite spriteWithFile:@"logo_select.png"];    self.selSprite.scaleX = 2.0;    id blink = [CCBlink actionWithDuration:2 blinks:2];    [self.selSprite runAction:[CCRepeatForever actionWithAction:blink]];    self.selID = 0;    //背景    CCTMXTiledMap *background = [CCTMXTiledMap tiledMapWithTMXFile:@"shopbg.tmx"];    background.scale = 2.0;    background.position = ccp(35, size.height / 2 - 200);    [self addChild:background];    //介绍标签    introduction = [[CCLabelTTF alloc] initWithString:@"勇士你好，你可以用经验值提升自己的能力" fontName:@"Verdana-Bold" fontSize:30];    introduction = [[CCLabelTTF alloc] initWithString:@"勇士你好，你可以用经验值提升自己的能力" dimensions:CGSizeMake(500, 100) alignment:UITextAlignmentCenter fontName:@"Verdana-Bold" fontSize:32];    introduction.position = ccp(350, size.height - 200);    [self addChild:introduction];    //加血标签    addGrade = [[CCLabelTTF alloc] initWithString:[NSString stringWithFormat:@"%d经验提升%d级",self.curExperience,self.curUpgrade] fontName:@"Verdana-Bold" fontSize:30];    addGrade.position = ccp(350, size.height - 260);    [self addChild:addGrade];    //加攻标签    addAttack = [[CCLabelTTF alloc] initWithString:[NSString stringWithFormat:@"%d经验增加%d攻击",self.curExperience2,self.curAttack] fontName:@"Verdana-Bold" fontSize:30];    addAttack.position = ccp(350, size.height - 320);    [self addChild:addAttack];    //加防标签    addDefense = [[CCLabelTTF alloc] initWithString:[NSString stringWithFormat:@"%d经验增加%d防御",self.curExperience2,self.curDefense] fontName:@"Verdana-Bold" fontSize:30];    addDefense.position = ccp(350, size.height - 380);    [self addChild:addDefense];    //离开商店    exitShop = [[CCLabelTTF alloc] initWithString:@"离开商店" fontName:@"Verdana-Bold" fontSize:30];    exitShop.position = ccp(350, size.height - 440);    [self addChild:exitShop];    //确定    enter = [[CCLabelTTF alloc] initWithString:@"确定" fontName:@"Verdana-Bold" fontSize:30];    enter.position = ccp(350,size.height - 500);    [self addChild:enter];    [self addChild:self.selSprite];    self.selSprite.position = addGrade.position;}-(id)initWithID:(int) shopID{    if ((self = [super init]))     {        if (shopID == 4)         {            self.curUpgrade = 1;            self.curAttack = 5;            self.curDefense = 5;            self.curExperience = 100;            self.curExperience2 = 30;        }        else        {            self.curUpgrade = 3;            self.curAttack = 17;            self.curDefense = 17;            self.curExperience = 270;            self.curExperience2 = 90;        }        [self viewInit];    }    return self;}@end

Buykey.h代码：

#import 
    
     #import "cocos2d.h"@interface Buykey : CCLayer {    CCLabelTTF *introduction;    CCLabelTTF *Key1Lable;    CCLabelTTF *Key2Lable;    CCLabelTTF *Key3Lable;    CCLabelTTF *exitShop;    CCLabelTTF *enter;}@property (nonatomic,assign)int yellowKeyPrice;@property (nonatomic,assign)int blueKeyPrice;@property (nonatomic,assign)int redKeyPrice;//当前选中商店编号@property (nonatomic,assign) int selID;//是否在购买状态@property (nonatomic,assign) int isOnShop;@property (nonatomic,retain) CCSprite *selSprite; -(void)viewInit:(int) shopID;@end
    

Buykey.m代码：

#import "Buykey.h"@implementation Buykey@synthesize yellowKeyPrice;@synthesize blueKeyPrice;@synthesize redKeyPrice;@synthesize selSprite;@synthesize isOnShop;@synthesize selID;-(void)viewInit:(int) shopID{    if (shopID == 5)     {        self.yellowKeyPrice = 10;        self.blueKeyPrice = 50;        self.redKeyPrice = 100;        [introduction setString:@"勇士你好，我这里有各种钥匙如果你有钱我可以卖给你"];    }    else    {        self.yellowKeyPrice = 5;        self.blueKeyPrice = 25;        self.redKeyPrice = 50;        [introduction setString:@"勇士你好，如果你有多余的钥你可以卖给我"];    }    [Key1Lable setString:[NSString stringWithFormat:@"黄钥匙(%d)",self.yellowKeyPrice]];    [Key2Lable setString:[NSString stringWithFormat:@"蓝钥匙(%d)",self.blueKeyPrice]];    [Key3Lable setString:[NSString stringWithFormat:@"红钥匙(%d)",self.redKeyPrice]];    [self removeChild:self.selSprite cleanup:YES];    id blink = [CCBlink actionWithDuration:2 blinks:2];    [self.selSprite runAction:[CCRepeatForever actionWithAction:blink]];    [self addChild:self.selSprite];    self.selSprite.position = Key1Lable.position;}-(id)init{    if ((self = [super init]))     {        //获取屏幕大小        CGSize size = [[CCDirector sharedDirector] winSize];        self.selSprite = [CCSprite spriteWithFile:@"logo_select.png"];        self.selSprite.scaleX = 2.0;        id blink = [CCBlink actionWithDuration:2 blinks:2];        [self.selSprite runAction:[CCRepeatForever actionWithAction:blink]];        self.selID = 0;        //背景        CCTMXTiledMap *background = [CCTMXTiledMap tiledMapWithTMXFile:@"shopbg.tmx"];        background.scale = 2.0;        background.position = ccp(35, size.height / 2 - 200);        [self addChild:background];        //介绍标签        //introduction = [[CCLabelTTF alloc] initWithString:@"勇士你好，我这里有各种钥匙如果你有钱我可以卖给你" fontName:@"Verdana-Bold" fontSize:30];        introduction = [[CCLabelTTF alloc] initWithString:@"勇士你好，我这里有各种钥匙如果你有钱我可以卖给你" dimensions:CGSizeMake(500, 100) alignment:UITextAlignmentCenter fontName:@"Verdana-Bold" fontSize:32];        introduction.position = ccp(350, size.height - 200);        [self addChild:introduction];        //黄钥匙标签        Key1Lable = [[CCLabelTTF alloc] initWithString:@"黄钥匙(10)" fontName:@"Verdana-Bold" fontSize:30];        Key1Lable.position = ccp(350, size.height - 260);        [self addChild:Key1Lable];        //蓝钥匙标签        Key2Lable = [[CCLabelTTF alloc] initWithString:@"蓝钥匙(50)" fontName:@"Verdana-Bold" fontSize:30];        Key2Lable.position = ccp(350, size.height - 320);        [self addChild:Key2Lable];        //红钥匙标签        Key3Lable = [[CCLabelTTF alloc] initWithString:@"红钥匙(100)" fontName:@"Verdana-Bold" fontSize:30];        Key3Lable.position = ccp(350, size.height - 380);        [self addChild:Key3Lable];        //离开商店        exitShop = [[CCLabelTTF alloc] initWithString:@"离开商店" fontName:@"Verdana-Bold" fontSize:30];        exitShop.position = ccp(350, size.height - 440);        [self addChild:exitShop];        //确定        enter = [[CCLabelTTF alloc] initWithString:@"确定" fontName:@"Verdana-Bold" fontSize:30];        enter.position = ccp(350,size.height - 500);        [self addChild:enter];        [self addChild:self.selSprite];        self.selSprite.position = Key1Lable.position;    }    return self;}@end

好了这两个类都有了，那么就让我们添加Game01.m里面的代码吧

这次我们要添加到if(npc_tileGid)里面：

case 4:     business = [[Business alloc] initWithID:type];     business.isOnShop = YES;     [self addChild:business];     break;case 5:     [buykey viewInit:5];     [self addChild:buykey];     buykey.isOnShop = YES;     break;case 6:     [buykey viewInit:6];     [self addChild:buykey];     buykey.isOnShop = YES;     break;case 7:     business = [[Business alloc] initWithID:type];     business.isOnShop = YES;     [self addChild:business];     break;

这样我们的“可用”npc又多了几个，之后我们会继续完善我们的npc,好了继续添加我们的代码：

if (business.isOnShop)     {        for (int i = 0; i <= 4; i++)         {            CGRect Rect1 = CGRectMake(200,                                      size.height - 290 - i*60,                                      400,                                      60);            //检测触点是否在控件区            if (CGRectIntersectsRect(Rect, Rect1))            {                if (i == 4)                 {                    if (herohp.Experience >= business.curExperience2)                     {                        switch (business.selID)                        {                            case 0:                                if (herohp.Experience >= business.curExperience)                                 {                                    _hero.HP += 1000*business.curUpgrade;                                    _hero.Attack += 7*business.curUpgrade;                                    _hero.Defense += 7*business.curUpgrade;                                    herohp.Grade += 1;

好了运行一下试试吧！

在这里我要感谢这几天大家对我的支持，你们的支持是我最大的动力！

还有请转载我文章的朋友们注意添加原文连接，谢谢！

在这里我补充一点内容就是之前的代码中钥匙商店没有初始化，我们需要在

Game01.m初始化方法中添加buykey = [[Buykey alloc] init];这样就行了。
