我把我即将到来的游戏作为国家科学学会目标的一个子类。这一类财产为锡石、锡石和所有 st子。但现在我有以下问题。

I want to schedule a method for animating the sprite. That action which should be scheduled every second. But because I m using a subclass of NSObject to hold all my data, I cannot use [self schedule:@selector(action:) interval:1.0]. Is there another way? I don t want to use NSTimer, because I then can t you the CCDirector anymore to break the game. It d really be helpful if you could help me. :-D

Answer 1

偷渡者,但这里有少数:

Subclass CCNode instead of NSObject and call [yourClass schedule: interval:]
Expose a simplified selector that internally calls [self.sprite schedule: interval:]
Externally call [yourClass.sprite schedule: interval:]
Internally call [self.sprite schedule: interval:]

Answer 2

//SomeObject.h
@interface SomeObject : NSObject 
{
}
-(void) initObject;
@end    

//SomeObject.m
#import "cocos2d.h"
#import "SomeObject.h"
@implementation SomeObject

-(id) init
{
    return [super init];
}

-(void) initObject
{
    [[CCScheduler sharedScheduler] scheduleUpdateForTarget:self priority:0 paused:NO];
}

-(void) update:(ccTime) dt
{
}

-(void) dealloc
{
    [[CCScheduler sharedScheduler] unscheduleUpdateForTarget:self];
    [super dealloc];
}
@end

并研究这一问题

[[CCScheduler sharedScheduler] scheduleSelector:@selector(ping) forTarget:self interval:2.f paused:NO];

-(void) ping
{
}
