cocos2d-iphone之魔塔20层第五部分
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

@property (nonatomic,assign) int Attack;
//防御
@property (nonatomic,assign) int Defense;
//金币
@property (nonatomic,assign) int Coin;

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
CCLabelTTF *yongshi = [CCLabelTTF labelWithString:@"勇士" fontName:@"Verdana-Bold" fontSize:45];
enemy.position = ccp(150, 400);
yongshi.position = ccp(900, 400);
[self addChild:enemy];
[self addChild:yongshi];
//标签1
enemyHpLable = [CCLabelTTF labelWithString:[NSString stringWithFormat:@"生命 %i",selenemy.HP] fontName:@"Verdana-Bold" fontSize:35];
enemyHpLable.anchorPoint = ccp(0, 0);
enemyHpLable.position = ccp(260, 530);
[self addChild:enemyHpLable];
//标签2
heroHpLable = [CCLabelTTF labelWithString:[NSString stringWithFormat:@"生命 %i",hero.HP] fontName:@"Verdana-Bold" fontSize:35];
heroHpLable.anchorPoint = ccp(0, 0);
heroHpLable.position = ccp(600, 530);
[self addChild:heroHpLable];
//标签3
CCLabelTTF* heroAttackLable = [CCLabelTTF labelWithString:[NSString stringWithFormat:@"攻击 %i",hero.Attack] fontName:@"Verdana-Bold" fontSize:35];
heroAttackLable.anchorPoint = ccp(0, 0);
heroAttackLable.position = ccp(600, 430);
[self addChild:heroAttackLable];
//标签4
CCLabelTTF* heroDefenseLable = [CCLabelTTF labelWithString:[NSString stringWithFormat:@"防御 %i",hero.Defense] fontName:@"Verdana-Bold" fontSize:35];
heroDefenseLable.anchorPoint = ccp(0, 0);
heroDefenseLable.position = ccp(600, 330);
[self addChild:heroDefenseLable];
//标签5
CCLabelTTF* enemyAttackLable = [CCLabelTTF labelWithString:[NSString stringWithFormat:@"攻击 %i",selenemy.Attack] fontName:@"Verdana-Bold" fontSize:35];
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。
完成之后游戏截图
