Calling Flash Remote Service in Flash with Zend amf

Steps:

1. Download Zend amf library and put it into your htdocs (www root) folder.
2. Create a Gateway.php for connection
3. Create your service using php
4. Connect to service using ActionScript in TestService.fla
5. Run the TestService.fla

Step 1:

1. Download Zend amf library: http://framework.zend.com/download/amf
2. Unzip and put the Zend folder into your htdocs folder

Step 2:

1. Create a folder named “service” under htdocs.
2. Create a Gateway.php under htdocs.
3. Gateway.php:

<?php
	require('./Zend/Amf/Server.php');
	//require('./services/HowAreYou.php');
	
	$server = new Zend_Amf_Server();
	$server->addDirectory(dirname(__FILE__) .'/services/');
	//$server->setClass('HowAreYou');
	$response = $server->handle();
	echo $response;
?>

Step 3:

1. Create your remote service “HowAreYou.php” under “service” folder



2. HowAreYou.php

<?php
class HowAreYou{
    /*
     * @param  string $receiveMsg
     * @return string $replyMsg
     */
	function sendStr($yourname){
		return "$yourname, 你好！";
	} 
}
?>

Step 4:

1. Write ActionScript in your TestService.fla file



2. In TestService.fla

stop();
var connection:NetConnection; // Initialize NetConnection Object
var responder:Responder;  // Initialize Responder Object
 
//Construct Instance
responder = new Responder(onResult, onFault);  // Show Receive Data
connection = new NetConnection; 
// Setting
var gateway:String = "http://localhost/Gateway.php"; 
connection.connect(gateway);  // Connect to Zend amf
// Data Receieve
function onResult(Result:String):void { 
   trace(Result);
}
// Fail
function onFault():void {  
    trace("Connection Fail");
}
// Call Remoting Service's Method: (Class.Method, reaonder, parameter)
connection.call("HowAreYou.sendStr",responder,"your_message");

Step 5:

1. Test(Run) your TestService.fla



2. you will receive “your_message,你好!”  on the output window

Produce Random Number with ActionScript

var randomNumber:Number;

Catch Keyboard Event (Key Down) with ActionScript

// catch Key Down Event

    trace(e.keyCode);

    if( e.keyCode == Keyboard.UP){

Using Global Variable in Flex

 

1. Declare the global variable in the main .mxml file.

 

In the main .mxml file :

<?xml version="1.0" encoding="utf-8"?>
<mx:WindowedApplication xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" creationComplete="TryAS()">
    <mx:Script>
        <![CDATA[
            public var bookSize:Rectangle = new Rectangle(0,0,800,600);

            public function TryAS():void{
                trace("Hello World");
            }
       ]]>
    </mx:Script>
</mx:WindowedApplication>

2.Use Application.application.yourGlobalVariableName to access the variable.

 

In the .as class you write :

import mx.core.Application;

// Application.application.yourGlobalVariableName

Application.application.bookSize.width

MDM + as3corelib : 存檔寫 log (文字檔 + 圖檔)

// MDM Version (http://www.multidmedia.com/)
// encoder from as3corelib (http://code.google.com/p/as3corelib/)

/*

如果你要它存 PNG 結果掛掉的話，有可能是因為 轉成 png 以後太大了
(記憶體佔用太多，血淋淋的經驗，死的不明不白，完全看不出來為什麼4 張只存了一張以後好像就沒動靜了)
可以先改用 JPG 存檔並調整他的壓縮比例 JPGEncoder(60)，這樣存的檔案體積會比較小，比較不容易掛

*/

import mdm.*;
import com.adobe.images.PNGEncoder;
import com.adobe.images.JPGEncoder;


//Declare global variables

var fileFolderPath:String; // 資料夾的位置
var fileName:String; // 文字檔(log)檔名
var uniqueName:String;

// 用 Flash CS3 的話一定要先用這個指令來 Initiate
mdm.Application.init(this,OnInit); 

// 可接收關掉程式時的 Event

SWF, EXE, MDM 的 exe 都能關掉程式的 function

import mdm.*;

mdm.Application.init(this,OnInit);
mdm.Application.enableExitHandler();

function OnInit():void {
//mdm.Dialogs.prompt("Zinc with Flash CS3, Text Saver!");
}

// 想關程式的時候就 call MyClose()

function MyClose(){
fscommand( "quit" ); // for flash player
mdm.Application.exitWithCode(0); // for mdm
}

/*
這樣子不管單純用 swf, or swf -> exe 都可以透過 fscommand 來關程式 (用 Flash IDE開發， Debug Mode的時候)

而在用 mdm 包裝後， mdm.Application.exitWithCode(0) 就可以關程式了

所以不管你是在什麼階段都能用。

Lesson 24 Using Shared Objects

Shared Objects 可以由複雜的資料結構組成(話是這樣說沒錯，但是目前的經驗是，也只有簡單的資料型別可以，BitmapData 等大型的東西就要轉成Byte 寫進去，再自己 parse出來了)。學到的重點是使用前最好 instantiate 給它 ex. example.data.accounts = new Array();。另外就是，如果存的東西比較複雜 ex. boolean + array => example.data.accounts = {hasWork:Boolean, buyBooks:Array}。

Chap 13 Exceptions and Error Handling

講的是 try/ catch/finally 的使用跟邏輯。有學過Java 的人應該很熟練。

Chap 14 Garbage Collection

Programmer 無法強迫System 做 Garbage Collection，甚至連提示它可以 collect 的指令好像沒有，所以一個objct 就算 reference 被設成 null，還是有可能繼續作用(這個還滿重要的，不是設成 null 就沒事了)。你只能自己讓 Deactivate Object(進入可回收狀態，回收時間仍然由系統決定)，也就是

1. 拿掉 Event Handler
2. 停止 timer 跟 intervals
3. 停止 playhead (不繼續播放)
4. 把唯一由自己reference 到的object 也 deactivate。

另外一點就是，如果可以重複使用一個Object就重複使用，而 不是因為方便就一直new，這樣很容易就會把記憶體用光(雖然， 這樣就可以觸發 Garbage Collection!!!)。

想把 MovieClip (-> Sprite -->DisplayObject) 恢復原來的大小

把 scaleX, scaleY ，設回 1 的時候就會恢復原來的大小

this.scaleX = 1.0;
this.scaleY = 1.0;

放大 Bitmap 的時候(或是內含Bitmap 的 DisplayObject) 可提昇Display 品質的參數

// 設定了 smoothing, pixelSnapping 後就好很多

var tempBitmapData:BitmapData;
var tempBitmap:Bitmap;
var temp_mc:MovieClip;
temp_mc = new MovieClip();

function mc2Bitmap(mc1:MovieClip):BitmapData {

var myBitmap:BitmapData = new BitmapData(mc1.width, mc1.height, true, 0);
myBitmap.draw(mc1);
return myBitmap;
}

tempBitmapData = mc2Bitmap( new WhiteBackBoy1());
// WhiteBackBoy1 : 有內容的 MovieClip (自這裡是把他的內容"印"成 BitmapData )

tempBitmap = new Bitmap( tempBitmapData );
tempBitmap.pixelSnapping = PixelSnapping.AUTO;
tempBitmap.smoothing = true;
temp_mc.addChild( tempBitmap );
addChild( temp_mc );

stage.addEventListener( KeyboardEvent.KEY_DOWN , KeyDownEventHandler);


function KeyDownEventHandler(event:KeyboardEvent) {
if (event.keyCode == Keyboard.UP) {
trace("Keyboard.UP");
temp_mc.scaleX *= 1.1;
temp_mc.scaleY *= 1.1;
} else if (event.keyCode == Keyboard.DOWN) {
trace("Keyboard.DOWN");
temp_mc.scaleX /= 1.1;
temp_mc.scaleY /= 1.1;
}
}

SharedObject 的 data 可以傳給其他 function 當作 reference 來改 data 下面的屬性的值

// 也就是說，你不一定直接用 shared object 的 data 下的屬性來改值，可以把 reference 傳給其他 function 後，讓那些 function 自己改

var bytes:ByteArray = new ByteArray();
var example:SharedObject = SharedObject.getLocal( "example8");
var tempList:Array;

var targetObject:Object;

function Target( o:Object ) {
targetObject = o;
targetObject.times = 10;
}
function AddTarget() {
targetObject.times++;
}

if ( example.data.times == undefined ) {
example.data.times = new Number();
var i:Number;
i = 0;
example.data.times = i;
trace("i:" + i); // first time, 0
trace("Before Target():" + example.data.times);// first time, 0
Target( example.data );
trace("After Target():" + example.data.times);// first time, 10
AddTarget();
AddTarget();
AddTarget();
AddTarget();
AddTarget();
trace("After 5 AddTarget():" + example.data.times);// first time, 15
example.flush();
}
else{
trace("example.data.times last time:" + example.data.times); // from the second time, 15
}

SharedObject 的data 下的屬性是多個屬性合成的時候的宣告方法

//bS:SharedObject
// bS.data.page1, bS.data.page2, bS.data.page3, ... bS.data.pagei 是我想存的資料(每筆資料有兩個成員 Boolean, ByteArray)
// cutFinished :Boolean
// cutPointLIst:ByteArray
// 記得要 new instance 給這些變數

bS.data["page" + i] = {cutFinished:Boolean, cutPointList:ByteArray};

bS.data["page" + i].cutFinished = new Boolean(); // 記得要 new instance 給這些變數
bS.data["page" + i].cutFinished = 你想給他的Boolean 值;
bS.data["page" + i].cutPointList = new ByteArray(); // 記得要 new instance 給這些變數
bS.data["page" + i].cutPointList = 你想給他的ByteArray;
bS.flush();
