这部分教程源代码连接

这一章我们就要开始在Game01.m文件中canMoveTo: 方法中的if循环中添

加相应的事件了，我在制作地图时图块都设置了其属性如图：

这里我就要获取其属性值

NSDictionary *props = [self.curtitleMap propertiesForGID:enemy_tileGid];NSString *value = [props valueForKey:@"enemy"];int type = [value intValue];

通过获取到的属性值来判断是那一类怪物，这里还得再添加两个类Enemy 和 Monster

为了有重点的讲解这里我就先不介绍这两个类了。代码如下：

Enemy.h代码

#import <Foundation/Foundation.h>#import "cocos2d.h"@interface Enemy : CCSprite<NSCopying>{}//怪物编号@property (nonatomic,assign) int enemyID;//怪物名@property (nonatomic,retain) NSString *name;//血量@property (nonatomic,assign) int HP;//攻击@property (nonatomic,assign) int Attack;//防御@property (nonatomic,assign) int Defense;//金币@property (nonatomic,assign) int Coin;//经验@property (nonatomic,assign) int Experience;//怪物行走动画@property (nonatomic,retain) CCAnimation *walkAction;-(Enemy*) initWithEmeny:(Enemy*) copyform;@end

Enemy.m代码

#import "Enemy.h"@implementation Enemy@synthesize enemyID;@synthesize name;@synthesize HP;@synthesize Attack;@synthesize Defense;@synthesize Coin;@synthesize Experience;@synthesize walkAction;-(id) copyWithZone:(NSZone *)zone{Enemy *copy = [[[self class] allocWithZone:zone] initWithEmeny:self];return copy;}-(Enemy*) initWithEmeny:(Enemy *)copyform{    if ((self = [super init]))    {        self.enemyID = copyform.enemyID;        self.name = copyform.name;        self.HP = copyform.HP;        self.Attack = copyform.Attack;        self.Defense = copyform.Defense;        self.Coin = copyform.Coin;        self.Experience = copyform.Experience;        self.walkAction = copyform.walkAction;    }    return self;}@end

Monster.h代码

#import <Foundation/Foundation.h>#import "cocos2d.h"#import "Enemy.h"@interface Monster : Enemy+(id)initWith:(int)typeID;@end

Monster.m代码

#import "Monster.h"@implementation Monster+(id)initWith:(int)typeID{    CGRect Rect;    Rect = CGRectMake(0, typeID*32, 32, 32);    Monster *enemy = nil;    NSString *name;    int HP,Attack,Defense,Coin,Experience;    if ((enemy = [[[super alloc] initWithFile:@"enemy.png" rect:Rect] autorelease]))     {        switch (typeID)         {            case 0:                name = @"骷髅兵1";                HP = 110;                Attack = 25;                Defense = 5;                Coin = 5;                Experience = 4;                break;            case 1:                name = @"骷髅兵2";                HP = 150;                Attack = 40;                Defense = 20;                Coin = 8;                Experience = 6;                break;            case 2:                name = @"骷髅队长";                HP = 400;                Attack = 90;                Defense = 50;                Coin = 15;                Experience = 12;                break;            case 3:                name = @"冥队长";                HP = 3500;                Attack = 1280;                Defense = 1000;                Coin = 112;                Experience = 100;                break;            case 4:                name = @"小蝙蝠";                HP = 100;                Attack = 20;                Defense = 5;                Coin = 3;                Experience = 3;                break;            case 5:                name = @"大蝙蝠";                HP = 150;                Attack = 65;

               Defense = 590;                Coin = 70;                Experience = 65;                break;            case 57:                name = @"金卫士";                HP = 850;                Attack = 350;                Defense = 200;                Coin = 45;                Experience = 40;                break;            case 58:                name = @"金队长";                HP = 900;                Attack = 750;                Defense = 650;                Coin = 77;                Experience = 70;                break;            case 59:                name = @"灵武士";                HP = 1600;                Attack = 1306;                Defense = 1200;                Coin = 117;                Experience = 100;                break;            case 53:                name = @"白衣武士";                HP = 1300;                Attack = 300;                Defense = 150;                Coin = 40;                Experience = 35;                break;            case 54:                name = @"灵法师";                HP = 2000;                Attack = 1110;                Defense = 980;                Coin = 100;                Experience = 90;                break;            default:                break;        }        enemy.enemyID = typeID;        enemy.name = name;        enemy.HP = HP;        enemy.Attack = Attack;        enemy.Defense = Defense;        enemy.Coin = Coin;        enemy.Experience = Experience;    }    return enemy;}@end

这里面的有怪物参数我自己修改了一部分。

根据获取到的属性值来实例化响应的怪物代码如下：

selenemy:当前选中怪物，应为要在其它方法里调用这个怪物的参数所以这里定义了一个属性。

这样我们已经实例化了怪物，那么接下来就要添加怪物的打斗界面了在打斗之前呢我们要判断

是否能够打过当前怪物所以再接着添加如下代码：

self.selenemy = enemy;int enemyHp,_heroHp;enemyHp = enemy.HP;_heroHp = _hero.HP;if (_hero.Attack > enemy.Defense) {  do   {     enemyHp -= (_hero.Attack - enemy.Defense);     if (enemyHp >0)     {        if ((enemy.Attack - _hero.Defense) > 0)         {            _heroHp -= (enemy.Attack - _hero.Defense);        }     }  } while (enemyHp >0 && _heroHp >0);}if (enemyHp <=0 ) {  [self creatFightScene];}

这里我没还要再添加一个创建打斗场景的方法creatFightScene。

-(void)creatFightScene{    FightLayer* fightLayer = [[[FightLayer alloc] initWith:selenemy.enemyID] autorelease];    [self addChild:fightLayer];}

写到这里我们还得再添加一个类FightLayer ,用于创建战斗场景，通过敌人的编号来创建相应

的场景。

FightLayer.h代码

#import <Foundation/Foundation.h>#import "cocos2d.h"@class Hero;@class Enemy;@interface FightLayer : CCLayer{    //怪物    CCLabelTTF *enemyHpLable;    //英雄    CCLabelTTF *heroHpLable;    //    Hero *hero;    //    Enemy *selenemy;}-(id)initWith:(int) type; @end

FightLayer.m代码

这里我只讲一下更新方法里面的代码，

if (selenemy.HP <= 0)     {        selenemy.HP = 0;        [self.parent removeEnemy];        [self.parent removeChild:self cleanup:YES];    }

这个是判断敌人是否死亡如果死亡则调用父节点消除敌人的方法，并把自己从父场景中消除

这个时候我们就要在Game01中添加removeEnemy方法。

-(void)removeEnemy{    [self.curtitleMap.enemy removeTileAt:towerLoc];    canmove = YES;}

好了到这里我们的勇士就可以和怪物打斗了

还有一个问题就是canmove这个变量主要就是控制勇士是否可以移动，在很多地方都有用到

前面updataMove方法里要添加一个控制，否则有时候怪物就消除不掉，需要添加的代码：

添加这样一个判断就ok了。
