为何没有眨眼的效果，但也不报错？

//baby eye

this.babyEyeTimer+=deltaTime;

if(this.babyEyeTimer>this.babyEyeInterval)

{

this.babyEyeCount=(this.babyEyeCount+1)%2;

this.babyEyeTimer%=this.babyEyeInterval;

if(this.babyEyeCount==0)

{

this.babyEyeInterval=Math.random()*1500+2000;//[,)

}else

{

this.babyEyeInterval=200;

}

}
