想问下果实为什么出不来,请问是怎么解决的
我也是怎么,请问是怎么解决的

if (this.alive[i]) {

}
else {
this.y[i] -= this.spd[i] * 7 * deltaTime;
}
ctx2.drawImage(this.orange, this.x[i] - this.l[i] * 0.5, this.y[i] - this.l[i] * 0.5, this.l[i], this.l[i]);
if (this.y[i] < 10) {
this.alive[i] = false;
}
}
}
}
//随机寻找海葵
fruitObj.prototype.bron=function (i) {
var aneid=Math.floor(Math.random()*ane.num);
this.x[i]=ane.x[aneid];
this.y[i]=canHeight-ane.len[aneid];
this.l[i]=0;
}
// fruitObj.prototype.update=function () {
// var num=0;
// for(var i=0;i<this.num;i++){
// if (this.alive[i])num++;
// }
// }
可以看出我哪边错了么 我找了好久 if (this.alive[i]) {}这个一加进去就泡泡就出不来了
先打印一下this.l[i]和deltaTime结果是否是正确的
