For some reason, no matter what I try, a stage instance named 'track' remains null to the frame it's on. I've made sure that Auto-declare stage instances is checked. Is anyone familiar with this problem?
View 1 RepliesI was just doing a menu system for a game project, as3 with Flash CS5. The navigation is build on the frame on the main timeline. When I was creating stuffs on the 3rd frame, the btns on the frame can not be called, returning "null", this is weird. With further study, I found that, if I delete a instance on frame 2, the problem on frame 3 will be solved. Then I found that giving the instance on frame 2 a name could also make things normal. What is happening? Why having a unnamed instanced on the previous frame could make the instances on the next frame "null"?

My scroll bar appears but when I trace stage into my ScrollBarClass this one is null trace(stage)
how do you disable the hand for a button instance so the pointer remains? this is for AS3.
View 7 RepliesI am using removeChild() to remove a MovieClip. And via tests, I can confirm that it's working fine ( stage.contains(mc) returns false ). But the MovieClip still does not seem to be removed, as if the stage is not updated correctly.
View 1 RepliesI've used a standard skin on an FLVplayback component which loads and plays perfectly. The problem arises when I enter fullscreen mode and then leave it again. Once I've done this, the video remains on the stage irrespective of what frame I'm on. I can even change scenes and the video remains in the middle. I haven't even added the video using actionscript so I don't really understand how it could possibly stay on more than the frame its inserted in!? At the moment I've used no ActionScript to control the video. I apologise if I'm missing something, this is the first time I've dealt with videos.
View 8 RepliesI have a named movieclip instance coming up undefined in AS2/CS3. the movieclip is on the stage, and I am having trouble accessing it from actionscript. does anyone have any ideas what might be causing the problem?
View 1 RepliesI have begun on a list: My reference is null!Stage is null! Convert this code from as 2 to as 3 for me! Crossdomain policies are in the way of my cool idea Dynamic property names I need to use stuff on the parent! I don't want my children to scale when I scale the parent! Classes vs instances. Mod note: I do not want this topic pinned, we will use a fresh topic once we have agreed to the content.

I have an html form page with a .swf navigation bar. I'd like to be able to click over to a second html page which contains a .swf file, and go directly to a named frame of that swf file.
Can I specify a named frame from the first html page like that?
I have a movieclip instance named 'placeholder' on the canvas, and I want to change the alpha of the named movieclip from it's class without effecting the alpha of all the movieclips of the same type. How would I specifically target the named movieclip instance that is on the canvas?
View 3 RepliesI'm trying to work on my first flash game but I'm already having problems making my character move.I'm currently following this tutorial:However, when I try to test my game, I get an error saying:"Access of undefined property player_mc"In the scene, I have a square MovieClip called "player" and when you select it, in its properties I have given it the instance name "player_mc".However I still get the error. So I decided to change the object's name to "player_mc" as well but that still gives me the error. I don't understand why this isn't working.According to this, it's just to do with spell-checking... but yeah, I looked through my code and the objects and it's all "player_mc".
View 2 RepliesI have an swf loaded into _level0. On button release I want gotoAndPlay a certain frame label in an swf loaded into an MC named Host on _level0 to. I have the following:
on (release) {
_level0.host.gotoAndPlay("Main", "MainStart");
unloadMovieNum (2);
}
The unload part looks fine, and I am back to my orginal page. But the page did not jump to 'MainStart'. What am I forgetting?
i have the following code in which im trying to add an item in a List Component which instance has been named "box". That "trace" function used there returns me "_level0.Game.replayMenu.box", so im not pointing to something undefined...
this = _root.Game.ui;
this._parent.attachMovie ("replayMenu","replayMenu",this._parent.getNextHig hestDepth ());
this._parent.replayMenu._x = 450;
this._parent.replayMenu._y = 250;
trace(this._parent.replayMenu.box);
this._parent.replayMenu.box.addItem("blablabla","b lablabla");
The problem is that my list simply doesn�t add any items at all, i've already tried using addItem({label:"blablabla", data:"blablabla"}), but it just don�t work.
i have 20 buttons, and i want to design an external file that holds the coordinates for each named button.
how would i go about this, since the external file would be read as a string by flash?

View 3 RepliesI am currently working with a contractor company that is hosting a flex based website. They are putting the swf files that I have developed into their flex site.The issue that I am having is that within my swf file I need to reference the stage.I do this by "MovieClip(parent).stage"... I do not use the keyword "root", I just reference my swf's root through however many "parent"s i need. It works fine when I publish on my own, outside of their flex site. When it is used in the flex site, they are getting an error that they cannot reference the stage/ stage is null. It is vital that I am able to reference the stage of my swf.

View 2 RepliesI've created an button object in flash. The button contains 2 layers. One is the background image and on top of it is a textField. The textfield is dynamic. I use the button inside a movieclip and I export it in a SWC. The I'm trying to use it in flex.
I'm trying to do this:
var myComponent:MyComponent = new MyComponent();
myComponent.button01.theTextField.text = "Caption";
I get and instance of the button(myComponent.button01 is not null in Flex debugger), but the instance of the textField(myComponent.button01.theTextField) is null and I'm not able to change the text(but the default text appears onscreen). The code is compiled correctly in flex.
I exported the in swc the button control as well. So the button is not the default SimpleButton from Flash, but an derived class generated by flash(with the same name as the symbol defined in flash). It contains theTextField memeber, which is null.
Here is the button timeline(Layer 2 contains the textfield, and the textfield instance is named theTextField):
I would like to know if there is a reason that, within an AS3 class, I would want to do something like this:
var myStageInstance:Stage;
//within an arbitrary class
var myStageInstance:Stage = stage;
myStageInstance.addEventListener(MouseEvent, someFunction);
as opposed to something that I would normally do:
//within an arbitrary class
stage.addEventListener(MouseEvent, someFunction);
There is no particular problem that I am looking to solve right now. I would just like to know if there is a reason to use one method over the other.
here is my new code that works for PART of my movie. i have two dynamic text boxes, one named "item" and one named "ssnumber" ssnumberNode works fine but itemNode does not. i bolded the parts that i think are relevant to the problems

In my document class named Engine, the stage variable is for some reason null:
package game
{
import flash.display.MovieClip;

This was working fine up until now. I just recently added two dynamic text fields into a symbol, and all of a sudden the stage is null. I really don't see the connection.
I'm doing a tutorial and I get this error about the "stage". I just copied the tutorial code.. what's missing ?

I am making a platformer and i got two problems with the hero.The hero is controlled with the following script.
code:
onClipEvent (load) {
var ground:MovieClip = _root.ground;
var grav:Number = 0;
var gravity:Number = 2;[code].....
1. I can't seem to figure out how to set the "hero" movieclip to the frame named "nothing" when none of the keys that control the hero are pressed. (so the hero is doing nothing). When the hero stands still, it will still appear like he is walking or jumping (whatever has been done last)How do i tell Flash that something must happen when none of a certain group of keys are pressed?
2.When you jump, the "jump" frame of the hero is shown. But as soon as you move right or left while jumping, the "right" or "left" walk frames are shown. How do i tell flash to not show the "right" or "left" frames after pressing the jump key until the hero lands back on the ground? The instance of the ground is "ground".
from my documentclass i got a isntance of the my view class in there i got a instance of navigation class extends Sprite I got a utilz.as file with all static public functions like this one
alignToCenter(obj:DisplayObject):vid
{
obj.x = obj.stage.stageWidth/2;
}
Utilz.alignToCenter(instance of navigation class)
I get a error stage is null reference..
I keep on getting "cannot access property of a null object" errors. With the debugger I pinpointed my issue at the line where I write stage.stageWidth.So somehow the stage is null. This is within my Document class which is linked with the .fla. The strange part is that I haven't had this problem until just recently.
View 6 Replieshow I access variables in a frame on the stage with code from a frame within a movieclip?(basically passing variables from a stage frame to a movieclip frame)
View 4 RepliesI have just recently started playing around with AS3 and am pretty new to what is going on in Flash (though I do have a lot of programming experience.) I have an object that I am dragging around on the mouse. I want it to be destroyed if I drop it anywhere but in a target location. I have the part where it is destroyed working, but I am running into a problem trying to find the target. When I try the following...
PHP Code:
public function DropObject(){
if (! this.hitTestObject(stage.getChildByName("Target"))){
stage.removeChild(droppedObject);
stage.removeEventListener(MouseEvent.MOUSE_MOVE,droppedObject.MouseCursorMove);
}}
I get "TypeError: Error #2007: Parameter hitTestObject must be non-null." So, "getChildByName" is returning null, but I'm not sure why. I've verified that there is an Instance name of the Target on the stage. Why can't I find it?
