Unity3D确实很酷

Unity3D是个真正的跨平台专业三维开发框架，支持各种三维游戏开发和网页三维插件，之前听说它也有一段时间了，本来想安装网页插件看看效果，但是并没有真心想去了解它，所以也就没有行动。昨天看了Unity3D is awesome!，想想4M的插件确实也不大，能够让everydayflash也惊叹的确实应该不简单。兴趣一下猛增，赶紧装来看看，结果确实让人叹为观止。


近乎真实完美的三维场景，我足足在那个天堂（Tropical Paradise）里面溜达了半个小时，相对Flash所能做出来的网页三维效果，Unity3D已经是非常成熟和先进。感叹之余希望可以从Unity3D里面学点一招半式，让我的三维世界更加丰富多彩。^_^

Publish Blog Test Through Google Data API

Blogspot.com has been banned by Great Fire Wall of China for a long time, but I can still use blogger.com to publish my thoughts.

However Blogger.com is just blocked by GFW in past few days unfortunately, no access from web absolutely. I try to keep find ways to access Blogger.com. This is my test to write my blog from Google Data API.

I had to... Damn it...

1. getDefinistionByName as Class

var className:Class = getDefinistionByName( StringName ) as Class;
var foo:Sprite = new className();

2. BitmapDataUnlimited

import com.formatlos.as3.lib.display.BitmapDataUnlimited;
import com.formatlos.as3.lib.display.events.BitmapDataUnlimitedEvent;

var bdu:BitmapDataUnlimited = new BitmapDataUnlimited();
bdu.addEventListener(BitmapDataUnlimitedEvent.COMPLETE, onBmpReady);
bdu.create(5000, 5000, true);

var hugeBmp : BitmapData;

function onBmpReady(event : BitmapDataUnlimitedEvent) : void
{
hugeBmp = bdu.bitmapData;
trace("BitmapData: w=" + hugeBmp.width + " h=" + hugeBmp.height);
}

e.g. a BitmapData with 12000 x 12000 px needs more than 1GB.

jQuery1.3.2在IE8下出现“Invalid Argument”错误的问题

今天给博客页头加了一个动画效果（鼠标点击会更换页头背景），用的是jQuery1.3.2，FireFox下一切正常，但是IE8出现"line: 4166 Invalid Argument"的错误：


原因不详，临时解决办法如下：

fx.elem.style[ fx.prop ] = fx.now + fx.unit;

改为:

if(fx.prop && fx.unit && fx.elem && fx.now){
fx.elem.style[ fx.prop ] = fx.now + fx.unit;
}
