AS3 flickr API

先申請Flickr API Key, non-commercial就可以了.

http://www.flickr.com/services/apps/create/apply

這個下方有列出很多可用的API

http://www.flickr.com/services/api/

我是用這個

http://code.google.com/p/as3flickrlib/

這個library會用到as3corelib, 所以先裝一下

http://code.google.com/p/as3corelib/

這個人為as3flickrlib寫了一個example

http://blog.organa.ca/?p=19

從上面這個網頁抓一下他的 flickrGrabber class

trace 他的code，再比對一下 http://www.flickr.com/services/api/

大概就知道怎麼用或hack as3flickrlib了...

BTW, 中文的keyword query，

必須先將query string用encodeURI()做編碼再送UrlRequest，否則flickr會回傳查無結果。
(這部分要感謝卡卡米教教!! :D)

下面是兩篇有用的參考:

要求Flickr在收到search request時丟回Photo list 的Thumbnail urls
http://www.flickr.com/services/api/flickr.photos.search.html
有個 extras (Optional) 參數
把"url_t" assign給extras, flickr就會在search result中加上<url_t>這個tag, 並且把 thumbnail url 內嵌在裡面丟回來。

Flickr limits
Query limits per hour to Flickr: 3600
Photo result limits per search query: 4000

Objects Sliding on Horizontal Floor (As if there is no friction)

http://www.box2d.org/forum/viewtopic.php?f=4&t=66
Right, there is no rolling friction in Box2D. I can certainly add this. I can also add linear/angular damping. I think I'll do the latter first. For now you can just multiply the linear/angular velocity by a number slightly less than 1 each time step (like 0.95). You can also generate some energy loss by reducing the friction. Then the circles will slide a bit more and slow down, instead of sticking and rolling.


I finally solved this problem by using b2Body.SetLinearDamping() 

Why Dynamic Bodies Are Never Sleeping in Box2D World ?

What's the fucking bug!!

http://www.box2d.org/forum/viewtopic.php?f=3&t=3501

I figured out why they aren't sleeping. If gravity is greater than 60 then the bodies wont sleep. With 2.0.1 bodies will sleep with gravity as high as 100. The same issue manifests for setting forces directly to objects.

Box2dAS3 Notes

Some weirdness to the b2ContactListener:

Problem: You can't alter your physics world from any function inside the contact listener.

Answer: Sometimes I like to set a flag and deal with the effects later.

Problem: The same contact might get called twice.

Answer: Not a big deal, just make a plan for it. Again, maybe a good reason to set a flag and deal with it later.

BlooDHounD - 比as3corelib還高速的加密API

ActionScript 3 Libraries

這個網頁有點熟悉，阿德你有po過嗎?
http://actionscript3libraries.riaforge.org/

A set of free and open libraries, written in ActionScript 3.0 for Flex and Flash developers.

Follow the External Project Link for links to source code & docs as well as the project group.

NOTE: These libraries are of beta quality and released as-is.


===============
corelib
===============

The corelib project consists of several basic utilities for MD5 hashing, JSON serialization, advanced string and date parsing, and more.

Project Page: http://code.google.com/p/as3corelib/
Project Group: http://groups.google.com/group/as3corelib

Authors: Christian Cantrell, Mike Chambers, Daniel Dura, Darron Schall
Dependencies: FlexUnit


===============
eBay
===============

The eBay ActionScript 3.0 library provides an interface between the eBay XML API and ActionScript 3.0. This open-source library will allow developers to create novel and innovative applications leveraging both eBay's marketplace services and Adobe's Flash Player 9 runtime! It is written in ActionScript 3.0, so any environment using ActionScript 3.0 can use this library, including Adobe Flex 2 and Adobe Flash Pro 9.

Project Page: http://code.google.com/p/as3ebaylib/
Project Group: http://groups.google.com/group/as3ebaylib

Authors: Charles Bihis, Darron Schall
Dependencies: corelib, FlexUnit
