(NO.00003)iOS遊戲簡單的機器人投射遊戲成形記(十二)

回到Xcode,建立Level1類,繼承於CCNode.

開啟Level1.m在初始化方法中添加如下方法:

-(void)didLoadFromCCB{    [self initBasket];    [self initRestrict];}

下面分別實現其中2個方法.

首先是initBasket:

-(void)initBasket{    CCActionMoveBy *mov1 = [CCActionMoveBy actionWithDuration:5 position:ccp(0, -0.7)];    CCActionMoveBy *mov2 = [CCActionMoveBy actionWithDuration:5 position:ccp(0, 0.7)];    CCActionSequence *seq = [CCActionSequence actions:mov1,mov2,nil];    CCActionRepeatForever *repeat = [CCActionRepeatForever actionWithAction:seq];    [_basket runAction:repeat];}

很簡單,就是用Action移動籃筐,並保持動作永遠迴圈.

下面是後面的Restrict方法:

-(void)initRestrict{    LevelRestrict *lr = [LevelRestrict sharedInstance];    lr.bulletCount = 10;    lr.timeCount = 60;    lr.scoreCount = 3;}

每一關都有特定的過關條件,類LevelRestrict就是用來儲存過條件的類,其中的bulletCount,timeCount和scoreCount分別表示該Level的子彈限制,時間限制以及分數限制.

在Xcode中建立LevelRestrict類,繼承於NSObject,修改LevelRestrict.h如下:

#import @interface LevelRestrict : NSObject@property (nonatomic,assign) NSInteger bulletCount;@property (nonatomic,assign) NSInteger timeCount;@property (nonatomic,assign) NSInteger scoreCount;@property (nonatomic,strong) NSString *levelName;+(instancetype)sharedInstance;-(void)print;

開啟LevelRestrict.m,實現單例方法:

+(instancetype)sharedInstance{    static LevelRestrict *sharedLevelRestrict;    if (!sharedLevelRestrict) {        sharedLevelRestrict = [LevelRestrict new];    }    return sharedLevelRestrict;}
