利用include as的方式新增/覆寫類別函數

 

利用include as的方式新增/覆寫函數, 可以使多種類別include需要的as而做群集性新增/覆寫函數.

 

- AddMethods.as

override public function sayHello():void { trace("Hello!"); } public function sayHello2():void { trace(this, " : Hello!"); }

- A.as

package { public class A extends SuperA { include "include/AddMethods.as"; } }

- B.as

package { public class B extends SuperB { include "include/AddMethods.as"; } }

- Main.as

package { import flash.display.Sprite; public class Main extends Sprite { public function Main() { var a:A = new A; a.sayHello2(); var b:B = new B; b.sayHello2(); } } }

用XML當做Dictionary的key值取出為undfined?

昨天在做Dictionary測試時本來用xml當做key mapping, 結果卻發現用迴圈將xml內資料重新取出return的值卻是undefined.

目前還在找原因為何:S

以下為示範code:

package { import flash.display.Sprite; import flash.utils.Dictionary; public class DictionaryKeyTest extends Sprite { public var data:XML = <root> <node label="node1" /> <node label="node2" /> <node label="node3" /> </root> public var nodes:Array = []; public var dict:Dictionary = new Dictionary(); public function DictionaryKeyTest() { //測試目的:用XML當做Dictionart key重新取出的值為undefined var key:*; for (var i:int = 0; i < data.*.length(); i++) { key = data.*[i]; nodes.push(key); dict[key] = "nodedata" + i; } for (i = 0; i < data.*.length(); i++) { key = data.*[i]; trace("isEqual:", key === nodes[i]); // return true trace(dict[key]); //return undefined trace(dict[nodes[i]]); //return value } } } } (Read more...)

撲克牌牌型排列組合

最近迷上了一款iphone game : sword & poker, 這款遊戲是運用撲克牌牌型做組合給予敵人傷害的回合制rpg, 相當的耐玩.

因此這幾天花了點時間找資料研究關於撲克牌牌型的演算法, 以下為成果:

希望有機會也能來嘗試作作這類型的遊戲. :D

QuickBox2D

QuickBox2D

QuickBox2D is a mini-library I created to work with Box2DFlashAS3. The main purpose of this library is to significantly simplify instantiation of rigid bodies and provide a simple way to skin rigid bodies with custom graphics.

可以讓你更為直覺快速建構Box2DFlashAS3物理碰撞環境.
讚! :D

ListBase設定CSS後ComboxBox下拉選單字體顏色設定失效問題

在flex開發的專案中有用到css設定顏色的功能, 最近遇到ComboBox設定color下拉選單卻無法起作用的問題.後來發現如果在List組件 or ListBase 設CSS color, 會造成ComboBox設定CSS color失效, 造成的原因可能是ComboBox所顯示的下拉選單是ListBase Class的緣故.

我想這應該算是CSS繼承邏輯上的認知問題, 應該不算是什麼bug吧 :p
在這邊特此記錄一下以免又遇到相同狀況.
以下為示範的code :



<?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute"> <mx:Style> ListBase { color: #ff0000; } /* List { color: #0fffff; } //*/ ComboBox { /*設定失效*/ color: #0000ff; } </mx:Style> <mx:List width="200" height="200"> <mx:dataProvider> <mx:Array> <mx:Object label="1"/> <mx:Object label="2"/> <mx:Object label="3"/> <mx:Object label="4"/> </mx:Array> </mx:dataProvider> </mx:List> <mx:ComboBox x="220"> <mx:dataProvider> <mx:Array> <mx:Object label="1"/> <mx:Object label="2"/> <mx:Object label="3"/> <mx:Object label="4"/> </mx:Array> </mx:dataProvider> </mx:ComboBox> </mx:Application>

AS3 Data Structures For Game Developers (AS3DS)

AS3 Data Structures
AS3 Data Structures (code.google.com)

'AS3 Data Structures For Game Developers' is a package containing common data structures useful for flash game programming and application development. The project was started because I wanted a unified library which I could reuse in my games.

裡面定義許多可以運用的資料結構類別, 對開發遊戲相當地實用. 如果有機會能夠開發遊戲一定要好好研究一下:D

教學範例參考:

the graph class
the tree class
the queue class
the linked lists class
