Is there a possibility to steer old style movieclip "on" handlers (like on(press), on(release), etc.) from as? For example can we assign content from them to some variable like for onPress or onRelease movie clip events:
mc.onPress = function() {
trace("pressed")
} var functionPressed = mc.onPress;
Is there a movie clip (or other class) property that match "on" handlers?
Can anyone recommend a good Steering Behavior engine? I like the engine explained in AdvancED ActionScript 3.0 Animation, but it doesn't accommodate limiting rotational movement, so often the Vehicles flip around, or spin.
View 2 RepliesI'm having trouble figuring out how to create onRollover handlers for movieclips loaded with loadClip. I can attach event handlers to the container clip, but not the child clips within it (the grandchildren). I'm using MX2004 / AS2.The parent clip just doesn't seem to "see" any grandchildren. It doesn't seem to be a paths issue, and I'm working in an onLoadComplete function to make sure everything's loaded first. The goal is to be able to change what happens on rollover with data pulled in (via Flash remoting) to the parent clip.
View 5 RepliesIn the code below, I have created an instance of the DrawLineChart class called LineChart1.When I test the movie, it shows up on the stage just fine and when I click on it, I can use a trace command to get a string statement written to the output window. However, now I want to be able to click on LineChart1 on the stage and have it be removed. When I do that, I get an error message 1120: Access of undefined property LineChart1.
why I'm unable to refer to my instance LineChart1 and what I need to do so that I can refer to it and remove it when it gets clicked? why the trace statement works when I click on LineChart1 during runtime, but not the removechild command.
package{
import flash.display.*;
import flash.events.*;[code]....
trace("hello"); // This works. When I click on the LineChart1 MovieClip on the stage during runtime, I get "hello" as an output. removeChild(LineChart1); // throws an error 1120: Access of undefined property LineChart1.
I have a MovieClip button control, I want to change the size of the displayed text of the label. I want to know whether there is a syntax to access the Label object of the MovieClip. I tried getChildAt(i) over the instance of the movie clip; but the label is a String property and is not a child of the movie clip instance.
View 3 RepliesI am building a dynamic movie clip scoller in flash the swf at the moment returns all the images from the db using an asp page and does display them side by side! I am using a method of loading that I am not 100% sure about as I need to make the whole thing scroll left to right style....and right to left....
The code for this loading is ..
myLoader = new MovieClipLoader();
function loadPics() {
myY = 0;
myX = 0;
for (i=0; i<=_root.image_array_length-1; i++) {
_root.attachMovie("image", "image"+i, i);
this["image"+i]._x = myX;
etc...
Now when I am making this scroll I am confused as to what to target to make scroll - the 'image' movieclip is in the library and uses linkage identifer of 'image' for the script... and also seems to sit on the highest layer/depth each time....

View 1 RepliesI've been using this site for a while and this is my first post. Recently, I've had some trouble using the onKeyUp handlers. It's really strange and I'm not sure whether it's a bug in the way I've lay out my code or the player itself.
But, whenever I used getAscii() or getCode() methods of using the keys to basically make stuff move, the first second of movement is really jittery. It'll move, pause still, then move properly. I don't get why though, it's the same code I've used in the same layoutof (Key.isDown(Key.etc...)) codes and those worked fine.
When, in ActionScript, an event is dispatched:
foo.addEventListener("some event", someHandler);
foo.dispatchEvent(new Event("some event"));
At what point are the event handlers executed?
I ask because I caught this at the end of an Adobe developer guide:
Notice that some properties are assigned to the [AsyncToken] after the call to the remote service is made. In a multi-threaded language, there would be a race condition where the result comes back before the token is assigned. This situation is not a problem in ActionScript because the remote call cannot be initiated until the currently executing code finishes.
But I could not find any information on what they meant by "currently executing code".

I have a text box (dynamic) whose value is being changed by javascript using the setVariable method. Bascially I'm now stuck in getting the flash application to recognise when the text box value has been changed, onKeyUp etc.. do not seem to work. The below code works if the user types in to the box, but if it is changed via JS it does not pick up the change, therfore not populating my variables. What Listener should i be using?

I noticed that in anonymous event handler this is referenced to global, not my class. I know that I can use outer referenced variables (because it creates closures), but how to get right this context?
Simple example:
_movieClipClassVariable = new MyCustomSpriteSubclass();
_movieClipClassVariable.addEventListener(MouseEvent.CLICK, function(event:Event):void {
trace(this); //gives 'global'
});
What about memory usage and garbage collection objects with anonymous handlers? Is declaring handlers as class method better?
SETUP: I have a MX2004 project where I'm attempting to pass a movie clip to a class, and have a method of the class act as the function for the onEnterFrame.

My project has a target object (center of stage) and a moveable object, which is created each time a user presses "Enter". Each movable object is identified as part of an array (i.e., object[i]), and a new line (i.e., line[i]) is dynamically drawn from the center of the newly created object to the center target object.
Basically, as the object is dragged around the screen the line is to stay connected to the target object. Therefore, that specific line for that object being moved must be redrawn using a drawLine function inside the event handler. My issue is how to get line[i] to be identified within the even handler? (Using AS3 coding)

What methods do you use to unit test event handlers, particularly if they require information from the event (such as mouse coordinates, or the target of the event)? Is the most common practice to just refactor the behavior into a method that does the lifting while the handler just extracts information from the event, or are there effective ways to simulate event dispatch in FlexUnit or Fluint?

load the swf once the flv is done playing? I think I'm just not loading the swf right because the flv plays correctly.
I came to AS3 from JS world, and I should confess that anonymous functions are my weakness. I tend to use them everywhere. Now, coming to AS3 I've heard and read in lots of places, that AS and Flash are enormously bad at handling garbage collection, that one should empty, dispose and remove all event handlers and objects manually to avoid weird and unexplainable memory leaks and crashes. Not sure what part of this is true, but I would like to follow best practices right from the beginning. How bad is idea of using anonymous functions as event handlers? Consider for example a code like this:
addEventListener(Event.ENTER_FRAME, function() : void {
controls.elapsed = stream.time;
});
Ccontorls.elapsed is the setter, which apart from setting current play time for video player, updates the whole UI, and stream is NetStream object, which streams the actual video. There are lot's of other places where anonymous function may make code cleaner and more intuitive. Check the following code for simple fade-in effect for the control bar:
public function showControls() : void {
var self:Controls = this;
if (!visible) {
visible = true;
fadeTimer = new Timer(30, 10);
[Code] .....
I totally like how it looks and fits into the code, but I'm concerned about leaks. While Event.ENTER_FRAME handler probably would never become harmful in this form, what about timer listeners. Should I remove those listeners manually, or they will be removed automatically, as soon as I set fadeTimer = null ? Is it possible to remove listeners with anonymous functions properly at all?
I have a method fired on mouse down:
private function setGender(e:MouseEvent):void

check.visible = true;[code]...
The same method body is shared by another method fired on a keyboard Event (so, it takes a keyboard Event for argument). Which is the best way to deal with situations like this one? I would like to have only one method.One way could be to create a new method called by the two event handlers (even if, if I need to use e.target, it can change according to the type of event and other variables, so I should eventually create a method that takes e.target as a parameter). This creates three methods...Would it be possible to change for example e:MouseEvent with a parent of MouseEvent and KeyboardEvent?
i have an odd issue and i know almost nothing about AS3 so im a complete noob please bare with me. I am working with a template .fla for a page flip but i am using a different navigation system for the flipping of the pages. I have worked through all the errors and output problems and i can get the system to work but the moment i try to use other event handlers for the same item it completely blows up the main script to make the page flip that is required. No errors, output problems etc, it just doesn't work. So here is the code.

'currItem.currVar', in my eyes, should be assigned the value of 'i' at that time in the loop, then move on to the next currItem right? Tracing 'currItem' traces 'menuItem. menuItem'+i to the output window fine, so im assuming that currItem is indeed a reference to a unique clip to which assign an action. The catch is, its not assigning the action I want, its assigning the value of 'i' at the end of the loop to all currVar's.I recently read a post explaining this conumdrum, stating that "variables are not "burnt" into functions when they are placed there. They will reflect the variable, where ever it may exist at the time it was requested, not at the time the function using that variable was defined," but in this case,since I am assigning the value of 'i' to anothing variable inside my dynamic movieClip.
I'm trying to rewrite a procedural ActionScript program as an OOP one: in the procedural version I set up event handlers for movieclips on the stage with a loop and it worked fine.However, when I put these event handlers in a class definition, it's no good.

myButton.addEventListener(MouseEvent.CLICK, clickButtonHandler);
myButton.addEventListener(MouseEvent.MOUSE_OVER, hoverButtonHandler);

Im tyring to turn a Movie Clip into a classic button - roll-over to display text, roll-off and text goes away, click and go to frame of animation. Each works on its own but when I put all 3 on the same Movie Clip (Tick1) each succeeding event listener seems to erase the previous one. Here is the code:
var txtField:TextField = new TextField();
Tick1.addEventListener(MouseEvent.CLICK, GoToStart);
Tick1.buttonMode = true;

I'm making a piece of flash used for a website banner, previously i've had very little experience with action scipt as i've made various animations only having to use simple functions such as "stop()" and i've made a never ending scrolling menu also, but now i want to have an event that "onPress" a small animation is played where the mouse clicked the banner. What would be the appropriate script to link the .swf i make to the "onPress" command?
