ActionScript 3.0 :: Changing The Symbol Associated With An Object?
Feb 15, 2009
I'm coming to AS3 from Director Lingo. In Lingo, a 'sprite' is vaguely equivalent to an object in AS3 and a 'cast-member' roughly corresponds to an AS3 library symbol. In Lingo I make a lot of use of lines likesprite("image").member = 25which changes on the fly the cast-member associated with a sprite, giving an instant image change when the user drags a dial, for example. This is particularly useful because the cast members in Lingo can be addressed by their sequence numbers as well as their names (giving a sort of implicit array addressing).In AS3 I can't see how to replace an image object with another image (not just a simple variation of the original). And even if I could do that, I can't see how to get the pseudo array addressing facility which I need to allow me to choose by code what image from perhaps several hundred will do the replacing.I guess what I'm asking for is maybe contrary to simple OOP.

I have a symbol that is a card, and it has text and it needs to have an image in the middle of it. The image will be different depending on the card. Do I need to have a different symbol for each card or am I able to insert or change an image within a symbol with actionscript 3?

I have several related projects. If I pull a symbol from the library of one project into another project, and then modify the symbol, shouldn't the changes appear in the original project too? Or is a new, project-unique symbol auto-created that has the exact same name as the one in the original library?I have a multi-scene cartoon with recurring characters, and would very much like to make modifications as I notice imperfections, and trust that the changes will appear in all instances. Is this possible?

I have a variable called "framenumber" and a movieclip(drawing) with six frames. Each frame of the movieclip has another drawing in it.In the main movie, this movieclip exists over several frames and keyframes. I even do a motion tween with the clip. Now what I want to do, is change the value of framenumber (for example 2) and then do a drawing.gotoandstop(framenumber). So then, the drawing in frame 2 of the movieclip should be shown. But here comes the problem. If I do that,the drawing (in frame 2 of the movieclip) only appears in the frame of the main movie where I put the drawing.gotoandstop(framenumber) command. But in the other frames of the main movie, the initial drawing is kept. How can I let the drawing change everywhere where the movieclip exists? So actually I want to know how I can change every instance of a movieclip, no matter where it is in the movie. Or maybe there's a way to change the (library) symbol itself, so that every instance of it changes along with the library symbol?

I have a movieclip simply animated with motion tween. On each keyframe, I made sure to name it introPhoto_mc.Now, before the movieclip first appears, I would like to change its content (just a picture change, dynamically loaded with loadMovie). But if I do so, then the next keyframe will obviously reset the instance to the original content.So I suppose I should modify the actual symbol so that every instance will have the desired content. What is the correct approach? OOP ?

Say I have "Symbol 1" in FLA document "DocOne". I drag this symbol from DocOne's library into "DocTwo"'s library. Now, in DocTwo's library, the properties for Symbol 1 show that the source is "DocOne". I can use the symbol update functionality to update it from DocOne. Is there a way to sever this linkage so that Symbol 1 in DocTwo no longer considers Symbol 1 from DocOne to be its source? So that, for example, if I drag it over from DocTwo to DocThree, Symbol 1 in DocThree, its source in DocThree will be DocTwo and not DocOne?

HJow to change frames within a symbol, by using a button in the actuall stage. Every time I try searching for it, I get lost in half completed answers, action script 2, and things that throw a ton of code and words and stuff at me, but never explain the parts of it.

I have a problem and I'm not really sure where to start. What I have is an animation of a character in the library. The Character is made up of a few movieclips for the body that move about and one for the face that holds a stock photo.I have a camera section that grabs an image of the users face and now what I need to do is swap the stock face photo for the one taken in the last scene.

I am trying to change the width and height of instances of a symbol programmatically. Basically, the symbol contains a few colored rectangles, a bitmap, and some text. I want to change the height and width of each instance of the symbol based on how low the text string is that is in the instance's text field, but the bitmap's size should always stay the same, 24x24 pixels.[code]The problem is that using this code seems to scale everything up, including the bitmap. I have tried to programmatically add the 24x24 pixel bitmap to the symbol programmatically after I changed the height, but it still seems to be scaled..

In Cs4, is there any reason why library symbols would at times change to green from the standard bulueish - purple? FYI, like the lil' gear box looking avatar like things at the left hand side of each library symbol. I have one that changes to green, but I can't seem to understand why? ANYONE?

I searched the forums, but couldn't really find anything that matched my specific needs. I have a movie clip symbol that is your character, I also have a movie clip symbol that is named fuel and it represents the fuel you have left. I tried this in your character:
if (Key.isDown(Key.UP)) {
yspeed -= ypower;
fuel._width -= 50;
}
as a little bit of code. fuel._width -= 50; is what I'm really interested in. yspeed-= ypower; is just my movement, which works. So why doesn't my fuel width change?

I want to add an animated .gif file to my movie. So I created a new symbol and then imported the .gif file to the stage. This created the symbol containing the animated .gif.I dragged the symbol onto the scene where I want it. However, the animation seems to play at a different speed (fps) than normal. So I changed the fps of the symbol (at bottom of Timeline where it says "fps"). But for some reason this changes the fps of the rest of the entire movie.

What is happening is, when I convert any object to any type of symbol, it disappears on my stage. It tests fine, but the symbol is invisible. This makes it difficult for me to see the overall design. Last time there was a folder that was just filled with about 10k blank files somewhere in the preferences for flash, but I can't seem to find it to delete those random files/ that folder. I'm on a Mac, and uninstalling/reinstalling flash does not work.

I'm creating an animation kinda like a travel map, x - - - - - - - - - - - - - - - - - - - - x .where the x's equal the start and the end point, and the dashs are like your direction etc, a good example is if you've ever seen those pirate movies where they have the maps and it shows where they have to go.is if there is a better way to do it than I currently am (Still finding my way around the whole Animation thing - and I'm sure theres an easier way than this!)
At the moment I'm going frame by frame and in adding objects, so for example, in frame one I have my 'x' object, then frame two I pasted the 'x' object plus one 'dash' objects, and so on and so forth, and I have a feeling that doing this is going to take agessss, and I'm sure there must be an easier way! I essentially need the 'x' object to span across ALL of my frames, is there a command or something for this? I'm not too knowledgeable with tweening, but can it be done with that?

I used to know how to do this (maybe): I want to load a Symbol from the Library on the fly into an Object on the stage. I think I have to give the Symbol a Class under Properties/Linkage, but after that I'm lost. I know this is a hack-y way to do it, but I want to do this without external Classes and files, all in the one swf.

In Actionscript 3, I'm trying to build a button to go back from a content frame to a main menu. When the button is clicked, IF the content frame has a movie in it, that movie should stop playing. Flash keeps throwing a "null object reference" error on all pages that don't include a movie. I even tried putting in a check to see if the movie exists, but that doesn't work, either.
ActionScript Code:
function return_to_menu( me:MouseEvent ):void {
if ( flashmo_contents.flv_movie ) { //this line produces errors in frames where the movie

I've got another simple question. I have a mc who's bitmap that is associated with him I want to change.
[Code]...
When BlankClip is first created, I want to tell it to either have the same image as Block_0 or Block_1. Looking it up online, it seems like I have to use BitmapData somehow, but I'm really unfamiliar with things...I've been working on this same code for about 2 hours...

For the first stage, I was able to build a walk-through demo in flash pro by creating buttons that when clicked caused the flash to change to different frames. easy enough. Now for the final part of this project, I need to make the interface fully interactive, as I was trying before. ie: you can click any button and lights go on and off or a loop counter increments, etc. Since there is logic involved and too many permutations to do a frame for each possible state, I'm back to trying to do this in an object oriented way. I've got some test code here.

debugger has some errors, so i don't know what exactly it will do. the errors are at the last two if statements where i'm trying to change the object property setting of the label. there is another error at the last curly bracket.
the idea is that there are two labels and a button. the first label starts out visible. when the button is clicked, a counter is checked, and incremented, then the counter is again checked and the appropriate label has it's visible property set to true. the intent is that in a list of several labels, pressing the button scrolls down them, until you press while on the last, which resets the counter and the first label becomes the visible one.

I'm having a game in which i control an MC with the keyboard arrows and when i click outside of the flash application and back in the MC loses focus. The focus changes to a button within the stage. What i've observed is that the Flash Player has a built-in control that moves focus from an item to the other with the arrow keys.

i am making this simple drag and drop game using flash cs3 using as2.i got 4 games and it has the same codes but different game type.. basically it uses drag and drop.here is the problem, when i finish the game, and press the back button to go to the selecting game scene, the last object dropped in the previous game stays and appears in the scene after that.
below is the as2 code i am using.

my designer made a fla file where he has animated layers loads of them. All the images inside those animations are loaded from outside the swf.
Now, the issue is at one point in time I want some of the objects to go under another object ( current their on top) . If I do this visually the images inside the swf(loaded) are lost.

I have a string of about 5 movieclips that are tweened so that when you click left or right they slide in that direction. When you click on the movieclips themselves I want them to:
on mouse down - move to (y-5)
on mouse-up - move back (y+5)
this all works fine, however after I have clicked on one of the movieclips to make it jump, when I click left or right to slide them all over again they don't slide with the rest of the clips anymore?

I know that you can change changeobject's color with AS3 is using colorTransform. However if I do this, then I can't really use filters. For example, if I apply DropShadowFilter on an object which color is changed with colorTransform, then the color of a shadow is the same as object's color. So I tried to use ColorMatrixFilter to change object's color. And it works with colors like FF0000, but it doesn't with colors like FFFFFF. IS there a way to change objects color to white using ColorMatrixFilter? I use the following methods:[code]
