ActionScript 3.0 :: Clear Many Instances From Stage At Once?
May 20, 2011
I am making a flashcard game with five subjects. It has buttons for moving forward and back,and buttons for switching to another subject The card instances for each subject are stored offstage, in separate frames (five in all), and their names are stored in arrays (five in all) Each time a button is pressed, the appropriate card tweens onto the stagepoint were still visible (not sure why, since the menu's on it's own frame), so I wrote a function to clear everything offstage whenever the menu button is clicked.My problem is weird: if you are in the math subject, switching to geography returns this error:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at flashcardapp1_fla::MainTimeline/frame3()
at flash.display::MovieClip/gotoAndStop()

I have two key frames on the Stage. The first one is empty; the actual movie starts from the second frame. Under some circumstances I have to clear everything on the stage and reload the movie. I remove all the movie clips and go back to the first frame. Unfortunately, it doesnt work with components. Can somebody tell me how I can remove everything from Stage? I tried btn.destroyObject(btn._name) but it seems it doesn�t work (the object cannot remove itself). And after several times I move back to the first frame, the components go broken

I'm doing a simple navigational menu and the idea is that when you rollover certain buttons, a linked movie clip appears in a certain spot and any other linked movie clips disappear off the stage. I heard about a bug with AS3 in CS4 and tried the following method but it's not working. All the movie clips stay on the stage. Nothing disappears. Where am I screwing up?

I am making my first website in flash based on frames. When you go to an other frame the Stage fades out. When you enter the frame you see nothing at all. So how can I clear the stage when entering the frame or even better it fades into the frame with clearing the objects & code of the previous frame.[code]...

I have added some movie clips to the stage using addChild method on Some Mouse Events.Now on an event say Mouse Double Click I want to clean the stage.I checked the Stage class from reference it does not have any method called clear.Neither I have stored the references of the objects, so that i can clear them using removeChild()

This would be done upon click of one of the buttons I have on the stage. That button also needs to execute a different class I have programmed. You can even just tell me what to search under to find out this data.xplanation: I have 2 different classes. Buttons class and Videos class. Buttons class loads the stage with 9 different buttons. Each button is supposed to lead to its own video. (I have the buttons ready with programming to load the video and all of the programming works). The Video class loads the video onto the stage and has the controls for it to play, pause, stop etc (works pretty much..).

Now, I am not sure what code to put under each of the buttons to clear the stage and load the Video class.

I'm working on a game whose background has many layers that each scroll at different speeds.
Inside each layer I have a Sprite, I've started using graphics.beginBitmapFill, but what I've found is that the graphics.clear() function doesn't actually clear the contents set by the previous call to graphics.begin.BitmapFill. Each frame, I adjust the matrix to shift the layer as needed. Then, I call graphics.clear() and graphics.beginBitmapFill() with the adjusted matrix. Since my layers have alphas in the bitmap, I can see the contents that was drawn the previous frame.

I have this library with more than 80 objects that i want to bind to my keyboard. My idea is use the "keyCode" to call the object to the stage, constructing the object's name inside a variable.This is the code that I'm trying to use, but the bold text line always give me an error (constructor, syntax and others) depending how i write that line.[code]I'm not very experienced with AS3 so i don't know if this is the right approach to solve my problem. Any help is well received.

I'm new to this OOP stuff, and I'm having a hard time understanding all of this.I'm trying to recreate in AS3.0 with classes a simple whack-a-mole game I created in AS2.0 using timeline coding.I've read through a lot of forums, but I still don't understand what exactly I'm doing wrong.Heres my setup:I have a movie clip named mrBunny (my girlfriend told me to change it to bunnies as moles were too ugly.). Now there are 6 instances of mrBunny on the stage, each named mrBunny0-5.The mrBunny symbol is linked to the com.mrBunny class.The class has a method called randomPlay(); which I use to randomize the animation times of mrBunny.I also have a button on the stage with the class stageBtn.
package com{
import flash.display.SimpleButton;
import flash.display.MovieClip;

I'm working with Flash Builder 4.6 as an IDE and Flash CS5.5 to create library items. The problem is - when I put an instance of a library item on the stage or inside of another item, Flash Builder fails to detect the instance name that was declared in Flash CS. This doesn't prevent the code from compiling just fine though.
I understand that the IDE only sees the fields that I have declared directly in the .as file, but it really hinders me that I the IDE goes crazy when I do this.
Is there any way to circumvent this - other than dynamically creating and placing the instances?

I was just wondering if there was a way to find all button/dynamic text instances that are on stage. This would allow the dynamic creation of array instead of having to manually create this array.

I have a stage instane called 'titleBox' in a SWF, which when loaded is dynamically filled in.
When testing straight from the SWF there is no problems at all, but when the SWF is loaded into the main SWF I get the error:
'Error #1056: Cannot create property titleBox'
Which I can't understand as it exists, any suggestion would be awesome.

Is there any way to iterate through instances placed manually on the stage in Flash IDE? For example I have 3 "Dog" class instances placed on the stage and I'd like to access them all from document class without giving them instance names.

Say, for example, I have a car on a flat plane. It can move either left, up, right or down. I also have 10 obstacles on the stage. Each time the car hits one of them it should automatically turn to avoid it. I could loop through each obstacle and check if it is colliding with the car but a better approach would be to make an obstacle class that checks if the car is going to collide with that obstacle and if it does, make it change direction. My problem though is what about if I had 5 cars? Would the obstacle class have to loop through each of the cars to check if any are colliding with it? My main concern with this is how much the performance of the program would be affected. I imagine with only 5 cars the difference would be insignificant, but what if I had 1000 cars and 1000 obstacles? Going back to the first example, it is easy to see how you can use a class as opposed to using a loop but with the second example, I just don't know.

Sometimes I got

Sometimes I got
[object SomeName]
I don't know why! I never click the "export for actionscript" and the symbol names in my library are given "Onename" "SomeName", rather than "MovieClip" ...

I'm writing a series of Search windows for an application. I create the FLA files on the stage, each has 3 simple buttons: next_btn, prev_btn, and close_btn. Those all have event listeners which call findNext(), findPrev() and closeWin() respectively. Each search window looks for different things, some with a text box and some with a combo, etc.
So I have a base class com.search that extends Sprite and adds the eventListeners at startup (actually, on addedToStage). Like this:
function isAddedToStage(evt:Event){
next_btn.addEventListener("click",findNext); prev_btn.addEventListener("click",findPrev); close_btn.addEventListener("click",closeWin);}
[Code]....
If I add the event listeners in the derived class rather than the base, it works fine. But that seems to defeat the purpose of inheritance, plus it infers that I won't be able to derive new classes/swfs from those derived classes.
how does one reference objects created on the stage from a base class of that document's class?

I have a number of instances of a MovieClip on stage. These are dragged onto the stage and arranged manually. Now, I would like to alter the instances during run time, using as2 code.
how can I name all the instances of the same MovieClip dragged onto the stage, using as2 code? (specify if the solution involves exporting the library MovieClip with an identifier name)

however I restructured my folders and now my .fla is in the /src/ with my MainApp.as ( Document class )
then MainApp creates a new instance of a class that is in /src/blah/blah/deep/
When this new as class is created it has a few buttons on it that are declared in the .fla as instance variables. I have turned off automatically declare stage instances.

I am working on a project in which I need to create a bunch of buttons.. all need to look the same with different text on the button.. rather then making each button separate in my library I would like to make one and create instances of the one button. I have created a button with a text field on top named txtLabel with a default text of "Label Here". I have dragged an instance of the button onto the stage and named it btnHome
btnHome.txtLabel.text = "Home"; d
Does not work..

From this example image attached, I have created many instances on my stage, let's say that for each instance I would like to go to a new section that has a different layout. What is the action script that will move my frame to the right location for example, let's say on one of the instance I have a button that says contact. On one of the buttons, what action script to I have to put in so that it navigates there when someone press it, I would think "on press" go to instance tab contact something of that nature.
