AS3 :: Flex - GetTimer() Method And The Timer Class?
Jun 18, 2009
I'm in the process of making a game (a shmup) and I've started to question the accuracy of the timers in ActionScript. Sure, they're accurate enough when you want to time things on the order of a few seconds or deciseconds, but it seems to perform pretty poorly when you get to finer ranges. This makes it pretty tough to do things like have a spaceship firing a hundred lasers per second.
In the following sample, I tested how long (on average) the intervals were between 1000 timer ticks intended for 30ms. Time and time again, the results are ~35-36ms. Decreasing the time, I found the floor on the timer delay to be ~16-17ms. This gives me a max fps of ~60, which is great visually but also means I can't possibly fire more than 60 lasers per second :-(. I ran this test a few times at 100 and 1000 loops, but for both the 30ms test and the 1ms test the results didn't change. I print to a textField at the end because using trace() and launching the swf in debug mode seems to negatively affect the test. So what I'm wondering is:
Is this test a decent measure of the Timer class's performance, or are my results questionable? Will these results change dramatically on other machines? I understand this is dependent on the getTimer() method's accuracy, but the discussions I find on this topic usually center around getTimer()'s accuracy on larger intervals.

I'm currently working on a detailed music media management application in Flash. There is a mp3 player which plays music and has a playback seeker (keeps track of current time for track and a tiny pin that that increases its x position as the track plays). I have a simple play & pause button that does appropriate functionality of playing & pausing the track, but the issue is that I have to pause the Timer associated with updating the playback seeker. The seekerTimer object has a delay of 1000 (1 second), while I'm listening to a track, the timer may have already excuted 600 ms, only waiting for 400 ms till the next timer event is dispatched to update the playback seeker. If I hit the pause button at 600 ms of execution time and I do a seekerTimer.stop(); and then a seekerTimer.start();, the timer does not resume its execution and instead restarts executing from 0 ms. This means that the playback seeker is not updated accordingly.
How can I pause the timer when I hit my pause button (essentially store the execution time), and then resume execution when I hit the play button? The play button doesn't have any parameters to start executing from a certain time. I looked at tutorials online but they all rely on the getTimer(); function, this returns a value of how long the Flash player has been running (from initialization). The issue is that the mp3 player in this Flash app doesn't initialize upon the application initalization (I know its a bit confusing).

I am trying to use a getTimer method that takes me to another frame (frame is "memory") after a certain amount of time after the movieclip has been loaded. The frame that I want it to go was given the name already. The timer itself does count when tested, but it just continues counting.

I'm making a racing game and am trying to have the final time displayed after I cross the finish line...In frame 4 (where the game begins) i have a setInterval timer that counts down from 20.when it reaches 0, my text is: startTime; where var startTime:Number = (getTimer()/1000).In frame 12 (where the game ends) i have
finalTime.text = endtime
// finalTime is a textbox
var endtime:Number = (_root.finishTime-_root.startTime);[code]...
when i finish the race, however, the word "undefined" is displayed in the textbox.

I have been developing a game using Flex, and used the Timer class to keep the main loop going. However, when I tried using the enterFrame event to do the main loop, there were a few problems. First of all, physics simulation seemed way too fast. Is the enterFrame event called more than once per frame? I set the application's global frame rate to 24, so shouldn't the application set off the event every 1/24 of a second? And the second problem is that when the game runs like this, some MXML components that are added are not shown.

If all I have is an instance of an object, can I call a static method of its class? For fun, let's say I don't know what the name of the class is, only the name of the static method.

I'm currently creating a website with AS3 in FlashDevelop, so it's code only no timeline stuff.
I have a class that loads images with a method that I call from my main source. I was wondering how I go about making sure that the images are loaded before executing more code outside of the class. I know how to do it using Event.COMPLETE in the image class, but I am unsure how to get the main class to wait.

I'm totally new to Adobe Flex Builder 3. I've been assigned a fully functional project but when I want to add the simplest function to any class, I always got the same error :
Call to a possibly undefined method through a reference with static type
For example, in some random class there is a function defined like this :
public function GetID() : String { return m_strID; }
If I try to define a new one like below :
public function GetIDFoo() :String { return m_strID; }
And then I try to call both of them like this:
trace ("This line is ok : " + oPhysicalScreen.GetID());
trace ("This line gives me an error : " + oPhysicalScreen.GetIDFoo());

I recently found a method (ByteArray.clear()) that FlexBuilder complains is possibly undefined; however, the method is in fact documented in the Flex LiveDocs. It must have been added in a later version of the SDK than I have installed. I'm not asking about this particular method, but I'm giving it as an example of the documentation issue that I'm trying to resolve. My questions are:
How can I determine what version of the SDK or Flash player that a method or property was added in? How can I tell which versions of the SDK are supported on which Flash player versions?
I want to be able to determine from the documentation, instead of compiler or runtime errors, what SDK and Flash player versions are needed to support newly added methods.
With Java I look for the @since javadoc tag when I need to know this, but I can't find an equivalent feature in the Flex docs.

I know that I can get info about constants, methods, etc of a class by using flash.utils.describeType. But I want to know if I can retrieve the asdoc comments of a class member.
I suspect, documentation is removed when classes are compiled into SWF so it might be impossible to get comments during run-time.

It's coming from this line of code:var dropTargetXML:XML = XMLTemplate.template.component.section.question.(@question_questionID == nNode.parent().@question_questionID)[0];nNode is an XML node sent as an argument to the function this is called in. The code runs,and does everything expected but the compiler sends out that warning. Do I have some formatting issue?P.S. I've tried telling it that it's XML like this:var dropTargetXML:XML = XMLTemplate.template.component.section.question.(@question_questionID == XML(nNode).parent().@question_questionID)[0];

I am interested in have a dynamic text field display three quotes at different intervals. I thought I could use the Timer to trigger these quotes by loading them into the dynamic TextField.
However, I cannot seem to get it going. I try to attach a number from the timer but that throws an error /1176: Comparison between a value with static type flash.utils:Timer and a possibly unrelated type int.

The error is 1061: Call to a possibly undefined method setResult through a reference with static type Class.

OK, from what I know actionscript in Flex runs asynchronously. I need the ability to run a method in a loop synchronously. Consider this code:
public class CustomerContainer extends VBox
{
public function CustomerContainer ()
{
[Code]....
This is not my exact situation as it is a bit more complicated to explain here. There is an abstract class and several custom view objects derived from it. Some of the views are dependent on others being completed first but I cannot seem to order them in the correct order. TIMERS are not an option. Probably not explaining this correctly.

I have a rather silly question but as3's document class always gets me confused.I have a public method on my document class. I want to call this method from another class that is instantiated from within an object in the library of the flash file (the same one on whose document class I want to call a method).

I have two classes:
1. DocumentClass
2. GameClass
I would like to be able to call a public method of DocumentClass from GameClass. I don't know how to do that, I tried instantiating an object of DocumentClass within GameClass which simply throws me into an endless loop and after a short while application crashes.

So how do I get this to work? I know that delete this will not work when defined inside the class. How do I target the .fla's instance name when I don't know what it will be called?

They are located in the same package and are both importing each other. I am trying to call a function from Class2 within Class1, but I don't know the syntax. I tried: Class2.godoThisThingNow(); But it gave me an error 1061, call to an undefined method. What's the proper syntax for this, and is it even possible in AS3?

I am developing a project where ClassA creates the instances of ClassB , ClassC and ClassD and adds the eventsDispatcher with them. ClassB and ClassC are able to dispatch the events back to ClassA which is fine. But ClassD is not dispatching the event. It only dispatch the event only when I call the dispatchEvent(new Event(Event.Complete)) function after giving 1 Second delay.

Does anyone know what could be possibly interfering with the Timer for this to happen? It mainly starts happening after you click on an mc and it is removed from the stage (this is for a game).
