cocos2d-iphone之魔塔20层第八部分
我的第九部分链接http://my.oschina.net/u/992577/blog/110651
为了感谢大家对我的支持这里给大家提供一下这八部分的代码下载
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 <Foundation/Foundation.h>#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#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];}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); } } } }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];
self.HP = 10000; self.Attack = 1000; self.Defense = 1000;
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：

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。
