为什么果实出不来了 求答案谢谢
var fruitObj=function()
{
this.alive=[];
this.x=[];
this.y=[];
this.orange=new Image();
this.blue=new Image();
}
fruitObj.prototype.unm=30;
fruitObj.prototype.init=function()
{
for(var i=0; i<this.num; i++)
{
this.alive[i]=true;
this.x[i]=0;
this.y[i]=0;
this.born(i);
};
this.orange.src="./src/fruit.png";
this.blue.src="./src/blue.png";
}
fruitObj.prototype.draw=function()
{
for(var i=0; i<this.num; i++)
{
ctx2.drawImage(this.orange,this.x[i], this.y[i]);
}
}
fruitObj.prototype.born=function()
{
var aneId=Math.floor(Math.random()*ane.num);
this.x[i] =ane.x[aneId];
this.y[i] =canHeight-ane.len[aneId];
}
