这是我的fruit.js
var fruitObj=function(){
this.alive=[]; //bool
this.x=[];
this.y=[];
this.orange=new Image();
this.blue=new Image();
}
fruitObj.prototype.num=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.blue.scr="./src/blue.png";
this.orange.scr="./src/fruit.png";
}
fruitObj.prototype.draw=function()
{
for (var i = 0; i < this.num; i++) {
//draw
//find a ane, grow,fly up
ctx2.drawImage(this.orange,this.x[i]-this.orange.width*0.5,this.y[i]-this.orange.height*0.5); //显示这一句有问题
}
}
fruitObj.prototype.born=function(i)
{
var aneID=Math.floor(Math.random()*ane.num);
this.x[i]=ane.x[aneID];
this.y[i]=canHeight-ane.len[aneID];
}
我的问题也是没实现
ctx2有没有写错,cxt2
楼主请问你的问题解决了吗?我的跟你一样的问题
this.blue.scr="./src/blue.png";
this.orange.scr="./src/fruit.png";
这里是src
