Professional :: How To Use Global Functions - Hold Parameters
Feb 25, 2010
I have about 10 as3 coded buttons that use the same AS3 coded parameters to control the font and filters of their text fields. I'd like to create a global function to hold these parameters, and then just call the function within each button, and then also code each button to have it's own myText.text = "blahblah"; I can set up a global function no problem using an external as file, but am having trouble getting Flash to accept the parameters. For example, the following parameters work fine when used within the text fields of the buttons, but as so as I try to put them in an external global function, Flash doesn't like the parameters being external:
I'm trying to find a way to have global functions in my as project, similar to how flash does with stuff like the util functions (describeType()...), where you can just call the function wherever you need it. For example:
[Code]...
So when I call Test(), it prints out "hello world" fine. My problem comes in that I can't change the name of the Test function, and I can't add any other functions without compiler errors. Is it possible to have a load of global functions in one file, or do I have to split them up into separate files like in the example? Also, I know that I can make a Global class and call static functions like Code: Global.doSomething() but I'd like to know if there's a way to do it as flash does it (describeType(), getDefinitionByName(), etc), or rather, how does flash do it?
I have some filters set up, and have assigned some global vars to them, which I then use in my Filters code to display the filters: myText:Filters [globals.data.glow1, globals.data.stroke1, globals.data.shad1] Works perfectly. Now I want to assign a global var to each global filter var to determine if it should be shown or not. So...
I have a button in a movie that I want to set a global variable to a new value when clicked. I want it to access a parameter of a movie clip that this same button loads onto the movie for the new global variable value. I have the final line under this button's onrelease script with something like this:
globalvariable1 = movieclip.parameter;
Everything is on level 0 and I've tried prefixing everything with _root. but it didn't make a difference, the global variable still wasn't changed. I'm a newbie so don't laugh if this is a really dumb question!
I'm tinkering around with things in AS3, and now that programming the reaction of buttons involves a bit more code, I'm trying to figure out how to kill a few redundancies.With the file I'm working with, at different points, using different objects, the user will click some specific thing to advance the main timeline one frame.Now, the way I've been doing it is, for each object, I have an addEventListener, which calls a function that only contains: MovieClip(root).nextFrame();So I've got, on every frame, unique functions that each require three additional lines of code -- I realize it's not much, and it's not a lazy thing, just an organizational, minimization thing.Since it's just that one thing, I don't see the point in making an entire AS file, so I didn't know if there was a way to make a function that could be called from any frame, from any object, rather than just have them local.
My question deals directly with ActionScript 3, although it could possibly appear in other languages. Consider the global trace function found in AS3. Calling the method requires no imports and is globally available from all classes. class A { public function A() { trace("Hello, A!"); // Hello, A! }}
Now, what if I create my own class method of the same name? In AS3, if I have a class method trace and then make a call to trace elsewhere in my class, the call is made to the class method over the global function. Essentially, I've blocked my ability to call the global trace method. class B { public function B() { trace("Hello, B!"); // no output } public function trace(s:String):void { // do something else. }}
Now, I know the obvious answer is to say, "don't create a class method called trace." But what if I'm unaware of the existence of the global trace function? Or what if I have a desire to "override" or "block" the global function? Is doing so bad programming? Or is this just another example of how AS3 is a poor object oriented language?
I have a .as file with a load of functions that i include using : include "myFunctions.as".They can be accessed alright.I have a custom class that extends movieclip, and i want to use a function inside that class that is located in my "myFunctions.as" file.How do i do that? Seems like the class loads before the myFunctions.as file so the functions are unavailable at this time. I get that error message :
I like reusing functions repeatedly so I pass the object to the function (blur, drop shadow, etc.) but if an Event or MousEvent function is involved, I have to do things I don't like. In my example, I had to put the TimerEvent.TIMER_COMPLETE function as a sub function of the setTimer function. I would rather keep the functions apart but I don't know how to pass a parameter to the event function to tell it what movieclip(timerObject) to fade in. Is there a better way to do this?
myFunc(tracer); function tracer(message:String):void{ trace(message);[code]........
Now, this works fine. But how can the function myFunc know, if the given callback function accepts the correct number and type of arguments in its signature?I want to avoid that I call something like this somewhere in my code:
myFunc(tracer2); function tracer2():void{ trace("done");[code]..........
Is there a way to do something like this, in order to use compiler warnings/error messages and thus avoid exceptions at runtime?
// Won't work :-(
function myFunc(callback(message:String):Function):{ callback("Hello"); }
I have a function fooA(valueA1, valueA2) which calls web method myWSA(). Upon reeiving the result, it invokes a result handler which inturn calls another web service myWSB(value2). I want to know how I can pass/access this value2 into foo2. These values: value1 and value2 are dependent on the button clicled.[code]...
I've got a symbol on stage and a button. The button rotates the symbol CCW half a degree. Code: on(release){ mySymbol._rotation -= 0.5;} I wanna add an on (press and hold) action on button so that the symbol will be rotated continuously when the button is on hold.. I can't make this work for over a week now.
I am using Flash CS5 and I have created a large, rarely changing framework that I don't want to be recompiled every time I use it in my projects.I must be doing something wrong because the "auto-complete" functionality doesn't show the names of the parameters of the functions.For example, I have a function:
public class Hey { public function show(name:String, num:Number, data:Array):void {...} }
I've created an image with a dozen irregular buttons. It all works perfectly. Now I want to edit my flash cs5 file in a way so that, when clicked upon one button, the last of the 4 states (the hitbox state) will remain visible until one clicks another button. Now its looping back to the fist state. Im sure there must be an easy way to do this, something with a stop code maybe?
I'm making a "master movie" for an assignment and I'm stuck right now. What I've got is an Intro page that will serve at the Parent.swf to load 4 other child swf's upon a mouse click. The problem is I have a theater stage where I tweened an animation to make it appear the curtain on the stage is going up but once it reaches it maximum height....the tween abruptly stops. I want it to HOLD there until a user clicks a button.
How would I make this happen? Here is the page in question: [URL]...

My global storage settings are set for 1) 'none' , 2)allow 3rd party..unchecked and 3) store common flash... unchecked. I can make changes but when i click another tab and come back to the storage settings tab every thing is still set for 'none' etc. This is true for all the tabs. no change I make is retained once another tab is activated or if I close the browser page. I have uninstalled flash and reinstalled. Searched and deleted every entry in the register that I thought may be relevant but no change. would like to be able to enable these options
trying to located imbedded movie symbols @ an exact location (relative to the root) and the X & Y values differ depending where the higher lvl movie symbol is located.
I right click in the window, the flash player window opens with a menu:Settings...Global SettingsAbout Adobe Flashplayer 10..I click on Global settings and nothing happens. I'm trying to delete a website, to remove the information they have stored on my PC. It's a game, Cafe World. It's been crashing, so they said to open the Global settings and click 'remove website'.I can't do this because Glob. Sett won't open!!what, such a simple error in a simple logical application.
I have created a map of Scotland, in Flash, with buttons for each region.As you can see (attached), it is pretty basic, with links off to a specific page of a website that I'm developing.1) When a region is clicked, on my current map, I have it redirecting to a page on the website with a QueryString value which populates the two "region" drop down menus. I'd like, when this happens, for the on state that was just selected (clicked) to remain in focus until a user rolls out onto another region. Is that possible? The problem I'm having is that when the map initially loads, I need it to be blank.2) How do I take a copy of images from Flash? I've tried exporting as a gif, but the colours are different and the text is awful looking
I need to dynamically pass 2 parameter to an swf movie to make it work properly, they are a number and a boolean. To do this I've changed the html page which contains the movie to php, I pass to the page the parameters' values through GET. The values are correctly passed to the page, I've tried to print them.
I build the call to the swf in this way collpreloader.swf?connid=<?php echo $_GET['connid'] ?>&animazione=<?php echo $_GET['animazione'] ?>
collpreloader.swf correctly reads the connid parameter, but animazione results always true.
From all the documentation and examples I can find, it appears that it would be correct to create a global array variable [outside of any functions] to load image names into, then use these images for a slideshow. I want to make the app dynamic, in that changing the text file gives a new set of images.
The global variable goes null [no values] after the load event listener. Why is that?
Isn't global, well global, and alive for the duration of the SWF?
I am a rank Flash newbie, so maybe I'm missing something obvious. In InDesign or Illustrator, if I want to change every red object to blue, I can go into the color list, edit the red color to the blue values, and every instance of red in the document reflects the edit. I don't have to select each red element and pick the new blue for stroke and/or fill.
I've recently downloaded the Flash CS5 and we wanted to upgrade license, but we experience VERY bad problem.Steps:
1. Create blank FLA AS 3.0 movie. 2. Add to first frame (stage), for example, TextArea component and name it "xxx". 3. Set in "Properties" window in "Component Parameters" tab:text - "hello world"maxChars - 10 4. Add script to first frame with next code:[code]
SO NUMERICAL PARAMETERS DON'T WORK! I not a new to Flash. Have worked more than 5 years with this. Also we've tested such behaviour with latest (downloaded today and yesterday) packages from OFFICIAL url...we've tested this behavoiur on different machines, with different operating systems.
