ActionScript 2.0 :: Changing Symbol And Every Instance Of It At Once
Jul 9, 2003
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 project in Flash Professional CS5 and ActionScript 3.
I have a movieclip symbol (referred herein as "background" with scripts on various keyframes inside of that symbol. I need to hide or show another symbol (referred herein as "object") sharing a stage with "background".
To put it another way, I need "object" to be hidden when "background" reaches a certain internal keyframe. However, as "object" and "background" are both children of the same stage, how do I do this?

well, i want to make an event occurred when object X hits any instance from a certain symbol Y lets say there's 10 instance of symbol Y rather than naming each of the instance obj1, obj2, etc and making a hitTest event for each of the instance, is there a way to make this event occurred when object X hits any instance of the symbol Y?

i'm trying to change the color of a graphic symbol instance, several times across the movie clip timeline. (the symbol is also rotating across the timeline.) for each keyframe, when i double-click on the graphic symbol, break apart and then change the color in the properties panel, then go back to the movieclip timeline, ALL the keyframes with that symbol has changed colors and not just the one instance on the keyframe that i'm on.

that symbols dramatically reduce the document file size. But, what if only one instance of a graphic symbol is to be used? Can I just use pure bitmap graphics from the library and not symbols in that case?

I'm just starting out with flash and I have a pretty simple question (I think). I was looking at this tutorial: [URL] ...th_slider2.htm and.. I was wondering why would we reference a symbol name sometimes and then other times we would reference a instance name. For example, in the example above in the actions layer we have this:

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'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 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 ?

Are symbols only supposed to be used when you need 100% exact copies of an object? So if you need to animate an instance of the symbol you can't use the symbol? Is that correct?

using AS to draw a shape, or loading in external files to a MC, etc. Basically, they're all overcomplicating it, as far as I'm concerned.
All I want to to is create an instance of a symbol on my stage.Let's say the symbol's name in the library is "picture_mc".How can I create an instance of that on-stage using AS2?

I have a symbol (of type movie clip) which is exported for action with AS3 as, say clsAux. From an AS file, I extend this class to program some methods to interact with it The movie clip has, inside, an instance of another symbol, and the instance is called objAux2. The problem I have is that, from code, from the class which is extending clsAux, I can't figure out how to access objAux2. I have tried, from clsAux, to make the movie clip gotoAndStop the frame where objAux2 is instantiated (where the keyframe where it is created is) and then access it like this.objAux2 (error), this[objAux2] (error)... is there any way I can access the instance of a symbol from code?

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 use a .png sequence for a sprite (primarily because it has the alpha channel) I will use in flash... its a walking animation of several frames. I make an empty symbol, load the frames into it. I put the symbol in the canvas. It animates fine and the alpha channel is working. Now I try to make a motion tween of the symbol instance, so as to simulate the walking movement, from one point to another. I playback [ENTER] its working fine, just as I want it.
Now if I do the [ctrl+ENTER] preview or export, the motion tween is working, the sprite is moving from point a to point b BUT the walk animation is NOT WORKING. Its just showing the first frame in the image sequence! Am I missing out something to make the image sequence animation work like it should? I tried to do the exact same thing to a movie clip (MOV) it works... but with the png image sequence I am really puzzled.

I have a symbol that I have already used and I would like to use the same symbol in another frame(s), except that when i edit the symbol the original object also edits, for example if i delete a part of it, it also deletes in the object that I have already placed, I have tried the 'duplicate symbol' method but nonetheless my symbol still gets modified and changes the way I want it to show it in certain frames.

I want to declare a variable in a class for an instance of an object that was added in the Flash IDE.
Example:
I have symbols for several types of panels that all subclass Panel.
To each panel symbol in the library, I add a button and give it an instance name "defaultButton."
This is really convenient, however, I want a defaultButton property for for my Panel class, and cannot find a way to do it. If I try adding a defaultButton property it throws errors:
ActionScript Code:
public class Panel: extends MovieClip{
public var defaultButton:Button; //as an example. Getters and setters also don't work
}
I also cannot check for the existence of defaultButton in code:
ActionScript Code:
public function GetDefaultButton():Button {
if(this.defaultButton)
return this.defaultButton;
else
Throw new Error("Panels are supposed to have a Button instance named 'defaultButton' added using the Flash IDE");
}
...possibly undefined error.
Is there any way for my class to enforce/ recognise the existence of the defaultButton instance added using the IDE in my Class?

I'm building a platforming game using AS2. I just got collision detection working between my character and multiple instances of an object. the different collisions (top, left, right, and bottom of platform blocks) are determined by a single symbol with 4 instances named for the different sides. this is good if i only want to have one block. is there a way to reference the symbol name in the actionscript or to have multliple instances of the same name to actually work?

I know this is one of the most basic things, but I am having trouble adding an instance of a symbol to the stage with action script in Flash CS4. I have a "fireball" symbol and at the beginning of my code I say:
var myFireball:MovieClip = new fireball;
addChild(myFireball);
But it says : "1180: Call to a possibly undefined method fireball."

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?
