can not access MovieClip properties in flashDevelop - apache-flex

I know there is something I am doing wrong. In my controls I have keydown events that control my hero. As of right now, I am trying to rotate my hero but he refuses to turn . Below is my Hero Class, my control class, and gameobject class. pretty much all the classes associate with the controls class.
package com.Objects
{
import com.Objects.GameObject;
/**
* ...
* #author Anthony Gordon
*/
[Embed(source='../../../bin/Assets.swf', symbol='OuterRim')]
public class Hero extends GameObject
{
public function Hero()
{
}
}
}
Here is my Controls class. This is the class where I am trying to rotate my hero but he doesnt. The keydown event does work cause I trace it.
package com.Objects
{
import com.Objects.Hero;
import flash.events.*;
import flash.display.MovieClip;
/**
* ...
* #author Anthony Gordon
*/
public class Controls extends GameObject
{
private var aKeyPress:Array;
public var ship:Hero;
public function Controls(ship:Hero)
{
this.ship = ship;
IsDisplay = false;
aKeyPress = new Array();
engine.sr.addEventListener(KeyboardEvent.KEY_DOWN, keyDownListener);
engine.sr.addEventListener(KeyboardEvent.KEY_UP,keyUpListener);
}
private function keyDownListener(e:KeyboardEvent):void {
//trace("down e.keyCode=" + e.keyCode);
aKeyPress[e.keyCode] = true;
trace(e.keyCode);
}
private function keyUpListener(e:KeyboardEvent):void {
//trace("up e.keyCode=" + e.keyCode);
aKeyPress[e.keyCode]=false;
}
override public function UpdateObject():void
{
Update();
}
private function Update():void
{
if (aKeyPress[37])//Key press left
ship.rotation += 3,trace(ship.rotation ); ///DOESNT ROtate
}//End Controls
}
}
Here is GameObject Class
package com.Objects
{
import com.Objects.Engine;
import com.Objects.IGameObject;
import flash.display.MovieClip;
/**
* ...
* #author Anthony Gordon
*/
public class GameObject extends MovieClip implements IGameObject
{
private var isdisplay:Boolean = true;
private var garbage:Boolean;
public static var engine:Engine;
public var layer:Number = 0;
public function GameObject()
{
}
public function UpdateObject():void
{
}
public function GarbageCollection():void
{
}
public function set Garbage(garb:Boolean):void
{
garbage = garb;
}
public function get Garbage():Boolean
{
return garbage
}
public function get IsDisplay():Boolean
{
return isdisplay;
}
public function set IsDisplay(display:Boolean):void
{
isdisplay = display;
}
public function set Layer(l:Number):void
{
layer = l;
}
public function get Layer():Number
{
return layer
}
}
}

Looks like your keyUpListener and keyDownListener methods aren't calling the UpdateObject function.

Try listening for your KeyboardEvent on stage instead of engine.sr (not sure what that is)
If you put them on anything other than the stage you will need to click that specific thing first to give it focus for the events to work.
Also, the line:
ship.rotation += 3,trace(ship.rotation );
in your Control class looks a bit broken.

PHPUnit Mocking Wrapper Instances

I have this wrapper:
class APIWrapper {
protected static $clientClass = \Hardcoded_API; // from a library
protected $client;
public function __construct() {
$this->client = new self::$clientClass(array_merge(self::$config, $config));
}
/**
* Does something.
*
* #throws SomeException
*/
public function act() {
$this->client->doSomething();
}
public static function setClientClass($clientClass) {
self::$clientClass = $clientClass;
}
}
Now let's say I am testing functions that make use of this wrapper:
class UnrelatedFunction {
public function callAPI() {
$wrapper = new APIWrapper();
try {
$wrapper->act();
} catch (SomeException $e) {
// ... do other things
}
}
}
class UnrelatedFunctionsTest extends PHPUnit_Framework_TestCase {
public function testUnrelatedFunctionException() {
$unrelatedFunction = new UnrelatedFunction();
$this->setExpectedException('SomeException');
// this call triggers the APIWrapper
$unrelatedFunction->callAPI();
// Some assertions here...
}
}
I need to be able to verify that UnrelatedFunction::callAPI() did its job recovering from the exception. In this case, how can I mock a \Hardcoded_API class, make it throw a SomeException when act() is called, and pass it onto APIWrapper::setClientClass() so that I can test the behaviour?

how to call an external function from inside a class?

i want to call an external function inside a class. thats the code;
in checkConnectionStatus function,
this[_funcNameForSucceededCon].apply(); doesnt work because "this" is the class, not the Application. How can i reach Application at this time or what can i do?
any help will be greatly appreciated.
best regards,
mira.
package myLibrary
{
import air.net.URLMonitor;
import flash.events.Event;
import flash.events.StatusEvent;
import flash.net.URLRequest;
public class connectionControl
{
private var _urlReq:URLRequest;
private var _urlMonitor:URLMonitor;
private var _funcNameForSucceededCon:String;
private var _funcNameForFailedCon:String;
public function connectionControl(targetURL:String, funcNameForSucceededCon:String, funcNameForFailedCon:String)
{
_urlReq = new URLRequest(targetURL);
_urlMonitor = new URLMoniotor(_urlReq);
_urlMonitor.addEventListener(StatusEvent.STATUS, checkConnectionStatus);
_funcNameForSucceededCon = funcNameForSucceededCon;
_funcNameForFailedCon = funcNameForFailedCon;
if(_urlMonitor.running == false)
{
_urlMonitor.start();
}
else
{
_urlMonitor.stop();
_urlMonitor.start();
}
}
private function checkConnectionStatus(e:Event):void
{
_urlMonitor.removeEventListener(StatusEvent.STATUS, checkConnectionStatus);
if(_urlMonitor.available)
{
this[_funcNameForSucceededCon].apply();
}
else
{
this[_funcNameForFailedCon].apply();
}
}
}
}
You have passed the name of the function to be serving as a callback. Use instead the function itself and pass it to connectionControl.
public class connectionControl
{
private var _funcSucceededCon:Function;
private var _funcFailedCon:Function;
public function connectionControl(targetURL:String, funcSucceededCon:Function, funcFailedCon:Function)
{
_urlReq = new URLRequest(targetURL);
_urlMonitor = new URLMoniotor(_urlReq);
_urlMonitor.addEventListener(StatusEvent.STATUS, checkConnectionStatus);
_funcSucceededCon= funcSucceededCon;
_funcFailedCon= funcFailedCon;
...
And:
if(_urlMonitor.available)
{
_funcSucceededCon();
}

accessing child movieClips FlashDevelop

I have a movieClip within another MovieClip. I gave the child movieClip the instance name "hSprite" and I added it to the parent movieClip stage. Now I get an error like the following.
[Fault] exception, information=ReferenceError: Error #1056: Cannot create property hSprite on com.objects.Hero.
If I remove the instance name from the child movieclip, then the error goes away. but when I add the instance name back, the error reappears again.
Keep in mind that both classes are set for export.
The parent class is embeded by a custom class which work perfectly fine. But the minute I give the child movieClip a instance name, the error starts up again.
Here is the class that embeds the parent class. What I initially want to do is access the child MovieClip that is in the Hero symbol
package com.objects
{
import flash.display.MovieClip;
import flash.events.*;
/**
* ...
* #author Anthony Gordon
*/
[Embed(source='../../../bin/Assets.swf', symbol='Hero')]
public class Hero extends GameObject
{
private var aKeyPress:Array;
private var jumpDisabled:Boolean = false;
//private var heroSprite:MovieClip;
public function Hero()
{
wY = 150;
wX = 90;
speed = .5;
aKeyPress = new Array();
TheGame.sr.addEventListener(KeyboardEvent.KEY_DOWN, keyDownListener);
TheGame.sr.addEventListener(KeyboardEvent.KEY_UP,keyUpListener);
}
private function keyDownListener(e:KeyboardEvent):void {
//trace("down e.keyCode=" + e.keyCode);
aKeyPress[e.keyCode]=true;
}
private function keyUpListener(e:KeyboardEvent):void {
//trace("up e.keyCode=" + e.keyCode);
aKeyPress[e.keyCode]=false;
}
override public function UpdateObject():void
{
Controls();
updatePosition();
}
private function Controls():void
{
if (aKeyPress[38])//Key press up
;//dy -= speed;
else if (aKeyPress[40])//Key press down
dy += speed;
if (aKeyPress[37])//left
{
dx -= speed;
}
else if (aKeyPress[39])//Right
{
dx += speed;
}
if (aKeyPress[32]){//space
jump();
}
}//End Controls
private function jump():void
{
if (!jumpDisabled)
{
if (onGround)
{
dy = -15;
jumpDisabled = true;
}
}
else
{
jumpDisabled = false;
}
}
}
}
You need to make the hSprite clip a public variable in the class.
public var hSprite:MovieClip;

Arraycollection not capturing the thrown event?

I have a collection of objects and each object throws an event every time its value gets updated. Im trying to capture that event by adding a listener to the arraycollection that holds it (see main class) but its not working. Honestly I'm not sure this is the correct approach.
I'm avoiding using Collection.CHANGE because it fells into an infinite recursion ultimately ends in a stack overflow. Any ideas?
[Bindable]
public class NamesVO {
public var steveList:ArrayCollection; // array of SteveVO objects
public function NamesVO() {
steveList = new ArrayCollection();
}
public function rename():void {
for each(var steve:SteveVO in steveList) {
steve.rename();
}
}
}
[Bindable]
public class SteveVO extends EventDispatcher {
public static const VALUE_CHANGED:String = "VALUE_CHANGED";
public var code:String;
public var name:String;
public var _quantity:Number;
public function SteveVO() {
this.code = "";
this.name = "";
_quantity = 0;
}
public function get quantity():Number {
return _quantity;
}
public function set quantity(quantity:Number):void {
_quantity = quantity;
dispatchEvent(new Event(VALUE_CHANGED));
}
public function rename():void {
name = code + " - " + _quantity;
}
}
Main class:
names = new NamesVO();
names.steveList.addEventListener(SteveVO.VALUE_CHANGED, function():void {
names.rename(); // this anon function is not being executed!!
});
var steve:SteveVO = new SteveVO();
names.steveList.addItem(steve);
// names is bound on a datagrid and uses itemeditor for each SteveVO object
The VALUE_CHANGED event is not dispatched by the steveList array Collection so won't be detected by your listener. You could encapsulate the functionality you want inside the NamesVO class by detecting when an item is added to the array collection and adding a listener to the new steveVO object that dispatches the same event from NamesVO. Then just listen for that event in your main class.
Is there a reason to change all the names when one quantity is changed. Would it be better simply to call rename inside the set function of the steveVO class?
To implement the change:
import flash.events.Event;
import mx.collections.ArrayCollection;
import mx.events.CollectionEvent;
import mx.events.CollectionEventKind;
[Bindable]
public class namesVO
{
public var steveList:ArrayCollection; // array of SteveVO objects
public function namesVO()
{
steveList = new ArrayCollection();
steveList.addEventListener(CollectionEvent.COLLECTION_CHANGE,collChanged);
}
private function collChanged(e:CollectionEvent):void
{
if (e.kind == CollectionEventKind.ADD)
e.items[0].addEventListener(steveVO.VALUE_CHANGED,valueChanged);
}
private function valueChanged(e:Event):void
{
dispatchEvent(new Event(steveVO.VALUE_CHANGED));
}
public function rename():void
{
for each(var steve:steveVO in steveList)
{
steve.rename();
}
}
}
In the main class use:
names = new namesVO();
names.addEventListener(steveVO.VALUE_CHANGED, function():void
{
names.rename();
});
steve = new steveVO();
names.steveList.addItem(steve);
steve.quantity = 12;
Of course this is only an example and only includes the case where one item is added at a time.

Flex: invalidateData

I've trouble getting my components to update when the params has changed:
package mycompany
{
import flash.events.Event;
import mx.events.SliderEvent;
import mx.controls.HSlider;
import mx.controls.sliderClasses.Slider;
public class FromToSlider extends HSlider
{
/* from: */
private var _from:int;
[Bindable]
public function get from():int
{
return _from;
}
public function set from(value:int):void
{
this._from = value;
this.values[0] = value;
invalidateProperties();
}
/* //from */
/* to: */
private var _to:int;
[Bindable]
public function get to():int
{
return _to;
}
public function set to(value:int):void
{
this._to = value;
this.values[1] = value;
}
/* //to */
override public function initialize():void
{
super.initialize();
addEventListener(SliderEvent.CHANGE, handleChange, false, 0, true);
}
protected function handleChange(event:SliderEvent):void
{
var ct:Slider=Slider(event.currentTarget);
this.from = ct.values[0];
this.to = ct.values[1];
}
}
}
When I set "from" and "to" the thumbs aren't updating. I've tried invalidateProperties but that didn't work.
Add a call to invalidateDisplayList() after invalidateProperties(). That will ensure that Flex redraws the component on the next keyframe.
You should also add the same to the 'set to()' function.
