me only still learning as3, i've checked google there and back, but somehow i can't find the answer for this: how to target a movieclip instance which is already on the stage from within a class file? i mean, targeting it from the document class file is easy, but what is i want to target it from another class file?
View 2 RepliesI've been searching around all afternoon, and am pulling my hair out. 1) I have a movieclip instance on stage (simple graphical element that represents platforms for a hero to run and jump along). I have placed it on the stage with an external class engine.as and in this class it is called myPlatform and is an object of Platforms.as. The movieClip is called platforms and from a trace(myPlatform.name) the instance name is instance3.
2) I am attempting to access the properties of myPlatform in an Enterframe event loop in my character control and collision class (called hero.as)
Basically here is the bit of code I am trying implement within Hero.as :
[Code]...
This all worked when I was writing actionscipt within the FLA file, on the timeline frame 1. I simply don't know how to access myPlatform from within the external Hero.as class! Do I need to create a variable? Is there a really easy way to do this with some syntax/command that I have not learned yet?
this is the code and the movieclips are target1_mc & target2_mc
package { import flash.display.MovieClip; import flash.events.MouseEvent; import flash.text.TextField;
public class recipeMC extends MovieClip {

I have a Bullet class - which defines and controls the firing of bullets (and works perfectly in all ways) - and now I'd like to add to it the ability to detect if it has hit a spaceship-movieclip sitting in my main .fla's timeline - what's the proper syntax to do this?
here's my code:
Code:
public function moveBullet(e:Event): void {
this.y = this.y - 20; // moves bullet up-screen, shooting vertically
if (this.y <= 0) {

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 am trying to target a TLF Textfield within a movieclip from that movieclips custom class, but the class can't find the instance name. When I trace out the child name it comes up with a random instance name, not the instance name I set on the stage. When I try and target it from the movieclip's timeline it works fine. Is there a class I need to include in my custom class, or is this a bug? I would love to move from dynamic text fields to TLF, but this is a big hurdle.

View 6 RepliesIs it possible to access the type of object being interacted with so I can create a new instance of the same object? So for example in the code below I have the movieclip myItem. After it's clicked it is removed from stage and then moved to the inventory. When I click on it there, is it possible to create a new instance of mcItemToDuplicate using the event information parameters? (while allowing myItem to be where it is).
My code looks something like this:
public function moveclip() {
var myItem:mcItemToDuplicate = new mcItemToDuplicate();
stage.addChild(myItem);

I'm trying to target a .swf that I loaded into a movie clip (mc_container) but it seems like I'm missing something. Can you take a look and see where I went wrong?
Code:
mc_container.loadMovie("mc_photoSwap.swf");
//homepage Animation Swap Images
function photoSwapAni(){
switch(random(3)){
[Code]...
Also I see I'm going to have an issue with the random part because it could call the same animation twice or more times in a row. Should I ad some sort of if statement or is there a better way to do this random part of the code?
I'm trying to create a new instance of a MovieClip when the original one has been used. Would sound easy enough. Just use: var
instanceName:ClassName = new ClassName();
the class name/mc in the library im trying to duplicate is MCg1 so
var instanceName:MCg1 = new MCg1(); right?
However, the particular object in the library i'm trying to duplicate has a base class that is an external class file (just to control it's drag drop functionality)... i.e baseclass is not set to the standard flash.display.MovieClip, or whatever the case maybe. So i end out with a: TypeError: Error #1009: Cannot access a property or method of a null object reference.
i am making a drag drop game. i created a doc class for the dragged items . i want to make the hit test with some movie clips on the stage but inside the class they are not seen by there names. how to perform my hit test

is there any way to target a MovieClip from an external class that's NOT the Document Class?
Is it correct to have the Document Class as Main AND View?
Is there any way to get the name of the MovieClip that a class extends?Lets say I have an MC on stage called boxMC exported for AS using a class box which extends MovieClip.If I trace (this) within my class I will get the name of the class, if I trace (parent) I will get the name of the main MovieClip that boxMC sits within. So how can I target boxMC?Basically I want to be able to return the name of the MovieClip that the class is extending
View 2 RepliesI have a main document class with another class instanciated (mouse follower.as) within it. I want the mouse follower class to access a stage instance. How is this done?
View 1 Repliesaccess one instance of a MovieClip on the stage (blue_mc) from within the class file of another MovieClip (red_mc).e.g. One instance of "Blue" on the stage called "blue_mc", and one instance of "Red" on the stage called "red_mc". Both symbols are linked to class files (Blue.as and Red.as).In Red.as, I set up a function to listen for a mouse down event. When this is triggered, I want to move the instance blue_mc. At the moment, though, I can't seem to get a reference to blue_mc.I've looked into the new stage and root properties, but even though blue_mc is on the stage, it cannot be accessed using stage.getChildByName( "blue_mc" ) either.
Code for Red.as:
Code:

import flash.display.MovieClip;

how can i access a movieclip via its instance name in another Movieclip class?
and a nother question how can i access a movieclip via its class name in another movieclip class?
BTW i want to access the movieclip child
I WIh know how Can I use a singleton class to make only a one instance of a movieclip on the stage.I use this code to make my movieclip instance:
Code:
var mioOggetto:wwp = new wwp();
mioOggetto.y = stage.stageWidth /2 -200;[code].....
im trying to access Stage Instance in other class but i cant

I need to know when an element is added to the stage (using main document class). So i use :
Code:
public override function addChild(__child:DisplayObject):DisplayObject{
super.addChild(__child);
trace("child added");
return __child;
}
Which works fine. I also use a static class, to which i pass the stage using :
Code:
public static function setStage(__stage:Stage):void{
_stage = __stage;
}
But if i add to the stage (_stage) a MovieClip from the static class, my "real" stage doesn't seem to get that something was added. So i guess _stage !== stage.
So why is this happening, why is _stage not getting the methods of stage ?
Is there a way to get an instance reference to the document class to call a method of it from the stage's timeline?I see that here's a possible solution: using a singletonOther solution I though of is using stage.getChildAt( 0 ) but it's not very nice.Is there an 'official' instance reference? because the document class is obviously instantiated at startup, but is that instance accessible in any way without having to use a custom solution like the ones mentioned?
