ActionScript 3.0 :: Check If An Event Object Is Equal To A Sprite
Jun 11, 2010Is there a way to check if an event object is == to a sprite. For example
Actionscript Code:
if(evt.target == [object Sprite])

I have two sprite object and they direct to same event like follows:
sprite1.addEventListener(MouseEvent.CLICK, mouseEventHandler);
sprite2.addEventListener(MouseEvent.CLICK, mouseEventHandler);
private function mouseEventHandler(event:MouseEvent):void {
//how to do it here?
}
When click spirt1 or sprite2,it will call mouseEventHandler function,my question is how to determine which sprite is click in mouseEventHandler function,sprite1 or sprite?
Is there a way to write an "ANY" conditional statement? For example, I want to write an IF statement that if the user presses ANY of 10 specified keys, I want to execute the same bit of code.However, the only ways I know to accomplish this is by
1) writing a switch statement, which seems unwieldy because I'll have 10 separate cases which all duplicate the same [code]...
Is there a better/faster/more efficient way to check if a variable is equal to ANY of a set of values?
Is there an easy way to compare two TextFlow objects with each other? I have two text flow objects that are created with TextConverter.importToFlow() and want to check if they are equal or not. Only way I found so far is to use TextConverter.export() to export them to a string then compare which seems bit convoluted...
View 1 Repliesi just wanted to know if it is possible to check in mouse event whether the object is grabbed or not in Action Script.
For example: youtube video player is also built in flash. and when we grab the track, it just stays with the mouse pointor and when we release it. it stops wherever we left it.
I have a brick class where I have created a rectangle using flash.display.graphics.I am using this brick class to create a grid of 10 X 10 in another class called grid using new brick() in a for loop.I have another class called ball where I have created a circle with flash.display.graphics.The problem is that I want to remove / destroy individual bricks when the ball hits the bricks on Event.ENTER_FRAME which is not happening.the error I get is shown only for the last brick that is created in a for loop.ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller.

at grid/ball_movement()// my function in enter frame event
The code I wrote in ENTER_FRAME is

View 1 RepliesI'm trying to set an array collection equal to a event.result that contains an array collection, but my array collection keeps coming up null. The event.result isn't empty because I can assign it as the dataprovider for a datagrid and that works (shows data correctly)[code]...
View 3 RepliesWhat's the best way to sort an array while making sure that elements of equal value stay in the same position?
When I do something like this:
var i:uint;
var myArray:Array = new Array();
myArray.push({num:1, type:0});
[Code].....
The objects that have equal num values swap places everytime I do a sort. So how do I get the sort to not swap the positions of objects that have the same value?
There are two Sprite's hit tests, one check the object (and have no precision on the curves) and the other check a specified (x, y) point. But, having curves drawn using Graphics.curveTo(), how do I check if 2 drawn curves are colliding?I'm not sure if this is an actionscript or a math problem..I want to check all (x,y) of a curve to all (x,y) of the other curve..

The dictionary use strict equals(===) for key comparison, how to change the comparison, so I can use my standard for comparison, for example, I have a class named Student:
class Student{
var id:int;
var name:String;[code]....
I want Dictionary use id to compare if the two keys are equal, not use strict equal(===) to compare if the key is the same.

View 1 RepliesCan't get Sprite to respond to custom event
View 3 RepliesI've got an app where numerous Sprite objects are being placed on the stage, and then when an event occurs (mouse click most likely) I want all the Sprites to move, independently, based upon an algorithm that each Sprite has. I can't get the Sprite objects to respond to the event; I get no errors.
Here's my Event class:
package {
import flash.events.Event;
public class MyCustomEvent extends flash.events.Event {

I have a actionscript "Sprite" class which load a transparent png. When i set a "mouseover" event over the Script, it is throw when the mouse goes over the "square" containing the transparent png. I would like a glow effect to be displayed on mouseover, but only when the mouse is on the displayable part of my transparent .png. How can i do to throw the event only when the mouse is not over the transparent part of the png? Do i have to check by myself in the mouseover handler then do what i have to do?

I'm currently working on a center stage component and I was wondering if there's a good way to detect when a stage component has been changed if any of the elements inside it have been enlarged?
This seems like it should be available but I can't find one that doesn't fire before the redraw. Or at all for that matter.
I have a sprite A which has a child, sprite B.Sprite B has a variable, instance of class C which only extends EventDispatcherIn class C, I dispatch a custom Event. The eventlistener in sprite B reacts on the event.The same eventlistener in class A doesn't respond.If I dispatch the same custom event in the eventhandler in class / sprite B, this event is seen in class / sprite A.Is there a difference in events going through the displaylist and those who are from an EventDispatcher?
View 6 RepliesI'm having trouble removing the an event listener as well as the sprite at the same time. I currently get an error:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
And if I comment out removeChild, I have no error but, obviously, the sprite remains on the screen. how I can rid myself of that error?

I'm trying to make a vieport in which you can pan by dragging the background image around. Here is what I've done: [URL] Note that I've hidden the mouse cursor and replaced it with 2 custom ones. The problem is, the event attached to the background, which is a touch event, fires even when the mouse is over a sprite/movieclip (the monkey or the stats) that's in front of that background. And the stats isn't even in the gameLayer (where the monkey and the bg and the mouse cursors are). Try to drag the stats around, and see that the background and everything else pans with it (this is unwanted). Also, I need to remove the custom cursor and show the regular cursor whenever the mouse is NOT on the background (i.e. when it's on the monkey or stats or any new sprites I may/will have in the future).

When I click mouse, there is nothing. If I change the event listener to listen EnterFrame event, that is OK. I didn't know why.
I have stuck a bitmap into a display object container (Sprite). On a given mouse event (i.e. mouse click), I would like to display the x and y coordinates of the bitmap. However, I've realized upon clicking on the bitmap, the event is only recognizing the higher level Sprite container. I suspect this could be attributed to the simple fact that bitmaps are not InteractiveObjects.If it's I have attached the code. I am loading a master image and cloning it to produce a thumbnail image (bitmap). Mouse events with the container holding the master image recognize the image itself while the container holding the thumbnail only recognizes the Sprite container.
Code:
var ldr1:Loader=new Loader();
var url1:URLRequest=new URLRequest("PhotoGallery0/picture0.jpg");

My Sprite class keeps losing focus when I click with the mouse - specifically after the MOUSE_DOWN event (before the click is complete).
I have set mouseEnabled to false on the children, no change. I added a listener for FOCUS_OUT and noticed that the FocusEvent.relatedObject property is NULL, which is confusing me - doesn't that mean there is no new focus target, the focus is just getting lost?
The exact sequence of events I get, by tracing them, as I click:
[FocusEvent type="focusOut" bubbles=true cancelable=false eventPhase=2 relatedObject=null shiftKey=false keyCode=0]
[MouseEvent type="mouseDown" bubbles=true cancelable=false eventPhase=2 localX=355

Taking my first steps coding in AS3. So I have my main class which extends sprite and I put new mc's on top of that. Using addEventListener on any child MC's with MouseEvent.CLICK works fine, but I can't add it to the main sprite. How can I register all clicks on the screen?

View 2 RepliesI have a an swf, called 'controls' that I created with flash cs4. I upload the controls.swf to my web server. I create an application in flex and it loads the external swf controls into itself. So far I can manipulate the controls.swf via my flex app. I created a class in my external swf, but I need to add some onResize event/check to my scroll bar. For example, if my scrollbar size increases/decreases, I want it to change variable values. Is there some movieClip.onResize event?
View 3 RepliesIs there a way how to check if UPLOAD_COMPLETE_DATA event was not dispatched after COMPLETE in Flash?
I'm working on file uploader. It uploads file after file - after COMPLETE next file starts uploading - this is repeated for every file. On last file on COMPLETE if there is no next file allCompleteHandler is dispatched and if some errors occurs it shows that errors at once trough javascript to the user.
I handle that errors in javascript - it stores every error to variable in javascript and after all completed it shows that errors.
