关于浮点行比较，基本比较范围

if (abs(_time*10 - _timefirst) <= 10)

{

    NSLog(@"%d,%d",_timeinterval,_timefirst);

id action = [CCJumpBy actionWithDuration:1 position:ccp(-30,220) height:40 jumps:2];

//int timeper=(int)(0.8*_timefirst);

     

 

_timeinterval=(int)(0.95*_timeinterval);

_timefirst = _timefirst+_timeinterval;

int score = (int)(3000/_timeinterval);

//_timeinterval=timeintv;

ScorelabNode *label = [ScorelabNode AddScore:score];

id actioncall = [CCCallFunc actionWithTarget:label selector:@selector(deleself:)];

id actionseq = [CCSequence actions:action,actioncall,nil];

label.anchorPoint = ccp(0,0);

label.position = ccp(60,50);

[self addChild:label z:5];

label.delegate=self;

[label runAction:actionseq];
