var momObj = function()
{
this.x;
this.y;
this.bigEye = new Image();
this.bigBody = new Image();
this.bigTail = new Image();
}
momObj.prototype.init = function()
{
this.x = canWidth * 0.5;
this.y = canHeight * 0.5;
this.bigEye.src = "./src/bigEye0.png";
this.bigBody.src = "./src/bigSwim0.png";
this.bigTail.src = "./src/bigTail0.png";
}
momObj.prototype.draw = function()
{
ctx1.save();
ctx1.translate(this.x,this.y);
ctx1.drawImage(this.bigEye,-this.bigEye.width * 0.5,-this.bigEye.Height * 0.5);
ctx1.drawImage(this.bigBody,-this.bigBody.width * 0.5,-this.bigBody.Height * 0.5);
ctx1.drawImage(this.bigTail,-this.bigTail.width * 0.5 + 30,-this.bigTail.Height * 0.5);
ctx1.restore();
}把main.js中这句代码注释掉看看：ctx1.clearRect(0, 0, canWidth, canHeight)
this.bigEye.Height => this.bigEye.height，小写的height
我的大鱼也没有出来，但是没有提示错误，你最后如何解决的呢？
我也是出现了和你相同的错误 你最后是怎么解决的？
f12看看有没有错误，如果没有错误，看看main.js中有没有调用大鱼的draw方法。
