Is there any difference, regarding the memory management, between the following:
Code:
var p:Point = new Point();
doSmthgWithP(p);
Code: doSmthgWithP(new Point()); I don't use this point again after the execution of doSmthgWithP function.
I had a bunch of movieclips on the stage and each of them gets assigned a variable called "clientName" onLoad.
I want to later reference the movieClip whose clientName was "foo" and changes its color, move it, make it bounce, whatever. It seems like it should be possible, but I don't know the syntax.
I've had this problem with Flash for awhile now and I've always been able to find a way to work around it, but this time, I think I'm just going to have to figure out a way to do it. Say I have a bunch of movieClips on the stage that have text fields in them that have data dynamically assigned to them from an SQL database. Once I've assigned data to these fields, can I reference a certain movieClip that contains a predefined value within its text field?
So, if I had three movieClips on the stage, with textfields in them that have the values "500" "600" and "700" is it possible to just reference the movieClip whose textfield currently says "700"? It doesn't have to be a just a textfield, either. If I could reference them by variables assigned to them. Like, it I assigned them a variable called "id" and the values were "500" "600" and "700" would it be possible to just reference the movieClip whose "id" is "700"?
As primitives are copied as 'value' not by Reference, this doesnt work:
ActionScript Code:
var myPrimitive1:int = 10;
var myPrimitive2:int = myPrimitive1;
myPrimitive2 = 20; // i want this to affect myPrimitive1 too
My goal is to pick a random property on a data Object() and alter that. My approach was to put all the Objects properties into an array, and then randomise that array, and pick the first element. The only problem is of course that, that element is no longer a Reference to the original, so If I change that it wont alter the original...
ActionScript Code:
// Create Data Object
var myObject:Object = new Object();
myObject.primitiveVar1 = "string1";
[Code].....
It took me hours to figure our why this was returning the wrong value - when assigning one array to another it passes by reference not Value. I need a way to force it to pass by values. e.g. copy the existing array and have the second array reference it, so i am free to modify the first array without changing the values of the second.[code]From the example above You see that in Actionscript when assigning one variable to another it does it my reference not value. So when you chage the value of one array it changes the value of the other automatically.I need to have the "test2" variable reference the "test1" array only by value so if modify "test1" the values of "test2" won't be modified.
View 7 RepliesHow can i reference variables inside of movieclips
i've tried.. mcname.variablename but it doesnt work...
also how do access a variable in the main timeline from within a movieclip.. i used to do it through _root.variable but that doesnt work anymore..
and lasty... how do i access a variable inside a class from within a movieclip?
If you have ClassA and ClassB, and ClassB contains a variable that references an instance of ClassA, what naming convention do you use for that variable in ClassB?I have used "classAReference" and "rClassA".
View 7 RepliesI'm trying to make methods available like so:
ActionScript Code:
MyClass.myFunc();
Instead of
ActionScript Code:
var myVar:MyClass = new MyClass();
myVar.myFunc();
I know that to do so I need to declare the functions/variables/constants as static:
ActionScript Code:
package MyPackage {
public class MyClass extends Object {
public static function myFunc():void {
} public function MyClass() {
[Code] .....
When I try to access the static function through the full reference (i.e trace(MyPackage.MyClass.myFunc);), it works, while trace(MyClass.myFunc); returns undefined. This contradicts what I've read in tutorials and posts on the Internet. They all use the short syntax, not the full path.
I am building a Gallery/Case Study application and I am running everything off of XML, and I need to be able to add images/text to the application whenever, without causing any problems. On the sideshow portion of the application, I am putting dynamically generated textfields under the picture viewer, with the number of the current image, highlighted. Similar to the one here:[URL] the first slide haha this was one of the best examples I could find. Anyway I've created the textfields, that display the correct numbers (that is, from "01" until say "07" depending on the .length(); of the XML tag <image>), but that is all they do so far. I am setting the type in the textfields by doing this
Code:
_tf.text = "0" + myIndex as String
myIndex is a varibale incrementing as long as var i:Number is less than the length property of the XMLList I'm using to store the image URL's. I am adding the _tf var to the stage using addChild(); and multiplying i by like 20 or something to make the x values different for every _tf. My problem is that if i try to reference the myIndex value when the textfield is clicked, it says the value of myIndex is 7, which is what it was set to when the last iteration of the loop executed. Basically I need to be able to store a value somewhere, that is unique to each textfield so I can load the corresponding image from my XMLList. I've tried messing around with the .name property of MovieClips, but I'm not exactly sure how it works. I use it earlier in the code with my Loader instance, but I don't know how to use it with MovieClips.
I need to remove the word Button from the reference to reference the actual item that will be tinted.

I'm having this frustrating error showing up and I have no idea why. Let me show you my classes and see if you can spot anything wrong.
First, here's my ILode interface:
ActionScript Code:
package com.schelterstudios.lodeSystem.flash.lodescode].....
So the problem I'm having is the compiler is throwing that 1000: Ambiguous reference error for any reference to instance.priority or instance.label. Why??? Instance is typed to IFlexLodeInstance, and IFlexLodeInstance lists method signatures of priority and label getters, and it inherits ILode, which lists method signatures for priority and label setters. What can I do to get the compiler to stop complaining?

Notice that I have 4 calls to console.log. The first 3 fire, but after the new GATracker statement, the 4th does not fire. I have a feeling that I'm overriding the entire package with the object created from new GATracker when I should be passing a different context. I believe the correct context I should pass is whatever this defaults to when not inside of a package/external file, I assume it references the main stage object.

I have an empty SWF that's sole purpose is to call loadMovieNum and start the project. Each loaded movie has a few variables defined within them - unique to those loaded SWFs. Instead of declaring all the variables in each SWF can I declare all of them in one place, in the first frame of the empty loader it all starts from? I'm thinking I can then declare a variable which each loaded movie can increment as needed for me.

How can I make a bunch of variables from a for loop. for example for (var i=0; i<total; i++) {var bunch(i);}. that i make a bunch of variables named bunch1, bunch2, bunch3. I keep getting errors. I program and use so many different languages that I dont know if that can be done with AS3. my only other alternative i can think of is to create some sort of event dispatcher object array. but I dont know how to get them all to send events to one listener with there index number.

I'm writing code that takes data from mysql that's processed by a PHP script. It's actually a bit bizarre, at least to me. Anyway, here's some basic AS3 code that's moving toward what I want to do:
var loader:URLLoader = new URLLoader();
var urlRequest:URLRequest=new URLRequest("receive.php");
urlRequest.method=URLRequestMethod.GET;[code]....
For some reason, the statement "trace(evt.target.data);" produces a whole pile of garbled text before the actual stuff that it's supposed to show Because of problem #1, I've had to include a throwaway variable at the beginning, otherwise the first variable I try to pass into AS3 comes back as undefined. This causes errors when I run my flash movie in the IDE, but when I run it from the browser it doesn't seem to have any effect.But this is the strangest thing of all whenever I make any changes to the database (and subsequently try to load data from different variables), the new variables come back as undefined. For example, let's say that I add another entry to the database, and decide to load students 2, 3, and 4 instead of 1, 2, and 3. When I do that, any new data I've added comes back as undefined, even though when I view the PHP output in my browser, it looks just fine.
And now for the REALLY bizarre part: I'll copy that output, paste it into my PHP script as an echo statement, comment everything else out, and my flash movie runs fine. Even though the output from the PHP script is exactly the same, it gives me errors.
There is a bird, and you control its upwards movement with a key. It has thrust, gravity, it works fine. The problem is I have a bunch of icicles that come at the bird that he is supposed to avoid. I tried this first with math random to use as an x coordinate and than move across the screen, but the icicles had the same x-coordinates sometimes. I tried does not equal(!=) but that doesn't work. I made an array and each number that came out of the array I assigned a different variable. This works fine. I put this variable into the x-coordinate such as mc.x=((n)*60)+480. I did this for five different icicles. All their differnt variables have a different value, and I put them into the same function for each individual video clip, but they still don't go to the right coordinate. Here is the test code just for the initial coordinate of each icicle before it moves...////////////////////////////Quote:

I am trying to load variables from a text file, and have them available from then onwards in the movie, globally so to speak.
While I can read the variable values in a loader function which executes when the text file is loaded, I don't seem to be able to keep those variables available afterwards.
I'm trying to figure out which is more efficient in terms of memory and speed. What I'm doing is having a series of messages loaded to the screen. Is it just faster to write them in string variable or in an XML document which is more versatile in terms of editing and adding on to the document.
