cocos2d-iphone之魔塔20层第五部分

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;

        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

#import "FightLayer.h"
#import "Enemy.h"
#import "Monster.h"
#import "Hero.h"
#import "Herohp.h"

@implementation FightLayer

-(id)initWith:(int)type
{
    if ((self = [super init])) 
    {
        //获取屏幕大小
        CGSize size = [[CCDirector sharedDirector] winSize];
        //背景
        CCTMXTiledMap *background = [CCTMXTiledMap tiledMapWithTMXFile:@"fightbg.tmx"];
        background.scale = 3.0;
        background.position = ccp(35, size.height / 2 - 150);
        [self addChild:background];
        selenemy = [Monster initWith:type];
        selenemy.scale = 4.0;
        selenemy.position = ccp(150, 600);
        [self addChild:selenemy];
        
        CCTexture2D *heroTexture = [[CCTextureCache sharedTextureCache]addImage:@"hero.png"];
        CCSpriteFrame *frame = [CCSpriteFrame frameWithTexture:heroTexture rect:CGRectMake(0, 0, 32, 32)];
        CCSprite *herosp = [CCSprite spriteWithSpriteFrame:frame];
        herosp.scale = 4.0;
        herosp.position = ccp(900, 600);
        [self addChild:herosp];
        hero = [Hero getHero];
        
        //怪物
        CCLabelTTF *enemy = [CCLabelTTF labelWithString:@"怪物" fontName:@"Verdana-Bold" fontSize:45];
        //勇士

        heroHpLable.position = ccp(600, 530);

        enemyAttackLable.anchorPoint = ccp(0, 0);
        enemyAttackLable.position = ccp(260, 430);
        [self addChild:enemyAttackLable];
        //标签6
        CCLabelTTF* enemyDefenseLable = [CCLabelTTF labelWithString:[NSString stringWithFormat:@"防御 %i",selenemy.Defense] fontName:@"Verdana-Bold" fontSize:35];
        enemyDefenseLable.anchorPoint = ccp(0, 0);
        enemyDefenseLable.position = ccp(260, 330);
        [self addChild:enemyDefenseLable];
        [self schedule:@selector(update) interval:0.2];
    }
    return self;
}

-(void)update
{
    selenemy.HP -= (hero.Attack - selenemy.Defense);
    if (selenemy.HP <= 0) 
    {
        selenemy.HP = 0;
        [self.parent removeEnemy];
        [self.parent removeChild:self cleanup:YES];
    }
    else
    {
        if ((selenemy.Attack - hero.Defense) > 0)
        {
            hero.HP -= (selenemy.Attack - hero.Defense);
        }
        [enemyHpLable setString:[NSString stringWithFormat:@"生命 %i",selenemy.HP]];
        [heroHpLable setString:[NSString stringWithFormat:@"生命 %i",hero.HP]];
    }
}
@end

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。
