My movieclip clipArt_mc receives movieclips that are loaded dynamically from a listbox selection using:
var myLoader9:Loader = new Loader();
I apply color to clipArt_mc using the following:
var trans3:Transform = new Transform(MovieClip(parent).design_mc.clipArt_mc);
I would like to access the nested or loaded in movieclip inside of clipArt_mc that has in it a movieclip named color_mc so that I can apply color directly to it instead of clipArt_mc.
Can this be done?
Thank you in advance for your time.

There are a few ways you can try to get the child MovieClip. In your case, it sounds appropriate to try to get the child by name. If the situation is as you say, you should be able to do this:
var child:DisplayObject = clipArt_mc.getChildByName(color_mc);
You can then apply the relevant transform to child.

I saw plenty of questions that asked how to make a button in a movie clip that leads to a frame in the main timeline, and took a look at them. But is it different if you want to go to a random frame in a specific set of frames? I've never really used AS3 aside from simple things like stop(); or gotoAndPlay.
Here's what my main timeline looks like at the moment:
Here's the code I've got so far by using Google:
var frameB:Array=[1,28,45,56,71,91,106,126];
blue_circle1.addEventListener(MouseEvent.CLICK, choose);
function choose1(event:MouseEvent):void {
var randomFrame:Number = frameB[Math.floor(Math.random() * frameB.length)];
trace(randomFrame);
gotoAndPlay(randomFrame);
}
The code works fine when I use it on the rotation buttons in the main timeline. But it doesn't work when I put it in a button in a movie clip. I need to change it so it works. If there is a better way of doing this, I'm willing to try it.
Edit: I should clarify things more. I got rectangle on wheels that moves left to right. It does this in a movie clip. I want the button to move with it. But when I place the button into said movie clip, the code on the button stops working. I hope I didn't end up making things more confusing.
When you place the button and/or code inside the movieClip it changes the movieClip that gotoAndPlay() is referring to. You need to specify which movieClip you are calling gotoAndPlay() on. For the main timeline gotoAndPlay() works, but inside a movieClip you must use this:
parent.gotoAndPlay(randomFrame);
Or you may need to set parent's type to a MovieClip like this:
MovieClip(parent).gotoAndPlay(randomFrame);
However, it's best to use external .as files as it gives you the most control over your code.
Save the code below in a file called 'MyFlashAnimation.as'
Create a folder called 'mycodefolder' and put it in the same directory/folder as your .fla.
Use the 'MyFlashAnimation.as' as your document class. In the Flash/Animate IDE find the Properties panel, then the Publish section
In the Publish section where it says 'Class' enter: mycodefolder.MyFlashAnimation (do not add the .as)
CODE:
package mycodefolder {
import flash.display.MovieClip;
import flash.events.MouseEvent;
public class MyFlashAnimation {
private var animationClip:MovieClip;
private var blueCircle1:Button;
private var frameB:Array = [1,28,45,56,71,91,106,126];
// constructor
public function MyFlashAnimation() {
// this your main robot/car animation
// this assumes animation_clip is on the main stage
animationClip = this.animation_clip;
// this is your button. this assumes blue_circle1 is a child of
// your animation_clip. update the path if necessary.
// for example, it might be: animationClip.robot_body.blue_circle1
blueCircle1 = animationClip.blue_circle1;
// add listener
blue_circle1.addEventListener(MouseEvent.CLICK, choose);
}
function choose1(event:MouseEvent):void {
var randomFrame:Number = frameB[Math.floor(Math.random() * frameB.length)];
trace(randomFrame);
// tell animation clip to gotoAndPlay
animationClip.gotoAndPlay(randomFrame);
}
}
}
That should work. If you have all your movieClip paths correct.
"The code works fine when I use it on the rotation buttons in the main timeline. But it doesn't work when I put it in a button in a
movie clip."
What is the instance name of the MClip you paste the button into? That MC name will "add" to the final path of your button.
Examples:
(1) If your blue_circle1 on stage (you already can do this) :
blue_circle1.addEventListener(MouseEvent.CLICK, choose);
versus...
2) If your blue_circle1 is inside another MClip (with example name as: thingMC) :
thingMC.blue_circle1.addEventListener(MouseEvent.CLICK, choose);

Very new to AS3. Sorry if this question is really basic, I tried looking around for the right answer but only found semi-related questions. Please help!!
Objective: I want multiple rollover MovieClips on the same stage that play out their animations independently.
So far, I have only 1 MovieClip object that behaves properly. If I add another, the first one behaves properly but the second doesn't appear at all. I understand that it's probably only calling the instance that I first dropped into the stage and that I need to change my code to have a "master" or parent MovieClip and that the instances should be the children, but I'm not sure how to write that in code. Eventually, the idea is that I add my children movieclips, and then slightly change the content in each clip.
My code so far:
import flash.events.MouseEvent;
clip_boxes.removeEventListener(MouseEvent.ROLL_OUT, clipOut);
clip_boxes.addEventListener(MouseEvent.ROLL_OVER, clipOver);
function clipOver(event:MouseEvent):void {
clip_boxes.addEventListener(MouseEvent.ROLL_OUT, clipOut);
clip_boxes.removeEventListener(MouseEvent.ROLL_OVER,clipOver);
clip_boxes.gotoAndPlay("Over");
};
function clipOut(event:MouseEvent):void {
clip_boxes.addEventListener(MouseEvent.ROLL_OVER, clipOver);
clip_boxes.removeEventListener(MouseEvent.ROLL_OUT, clipOut);
clip_boxes.gotoAndPlay("Out");
};
There are a few ways you can do this. I'll list in order of worst to best.
Manually add listeners to each instance.
When you drag a new MovieClip onto the timeline, you need to give it an instance name (found in the properties panel). I'm not sure if clip_boxes is a parent timeline that you intend to have all your movie clips on, or if it is one of your movie clips itself.
Assuming you have 3 clips with the instance names: MC1,MC2,MC3, you could do this (on the first frame of the timeline that contains them)
MC1.addEventListener(MouseEvent.ROLL_OVER, clipOver);
MC2.addEventListener(MouseEvent.ROLL_OVER, clipOver);
MC3.addEventListener(MouseEvent.ROLL_OVER, clipOver);
//If you had a whole bunch, you could also use a loop to add all the listeners
//you use event.currentTarget to get a referce to the object the listener was attached to - this way you only need this one handler function
function clipOver(event:MouseEvent):void {
MovieClip(event.currentTarget).addEventListener(MouseEvent.ROLL_OUT, clipOut);
MovieClip(event.currentTarget).gotoAndPlay("Over");
};
function clipOut(event:MouseEvent):void {
MovieClip(event.currentTarget).removeEventListener(MouseEvent.ROLL_OUT, clipOut);
MovieClip(event.currentTarget).gotoAndPlay("Out");
};
Use Inheritance
This would involve creating a base class file (.as file) that you can then attach to all your MovieClips so they inherit all the code within. Here is an example of a class file that would do this for you: (lets assume this is a file called SubClass.as in your root directory)
package {
import flash.display.MovieClip;
import flash.events.MouseEvent;
public class SubClass extends MovieClip {
public function SubClass(){
this.addEventListener(MouseEvent.ROLL_OVER, rollOver,false,0,true);
}
public function rollOver(event:MouseEvent):void {
this.addEventListener(MouseEvent.ROLL_OUT,rollOut,false,0,true);
this.gotoAndPlay("Over");
}
public function rollOut(event:MouseEvent):void {
this.removeEventListener(MouseEvent.ROLL_OUT,rollOut,false);
this.gotoAndPlay("Out");
}
}
}
Now, when you create your movieClips (or right click in the library and select properties), you can set a baseClass for them. If you set the base class to the class above, they automatically use the code above and have the mouse over/out attached. (as long as they have the Out/Over frame labels it will just work).
Can you also post the code where you add clip boxes to the stage? Did you add them in the GUI by dragging and dropping or in code?
If so, you might need to make instances of each of the clip boxes inside the larger movieclip that contains all of them together. Then you'll need to refer to each one with clip_boxes.box1, etc.
EDIT:
Oh, I see you had an image there. My bad. Make sure you give each clip box its own unique instance name. You'll need to have clip_box_1, clip_box_2, etc. Then in code you use clip_box_1.addEventListen.....etc.
this is actually a noobish question, but is there a possible way to save a certain state of a movieclip?, example i dynamically added a movieclip called big_mc, then inside big_mc contains three(3) smaller movie called child_mc1 and child_mc2 and a close_big to remove big_mc from the stage, when i click either of child_mc1 and child_mc2, the child_mc will disappear prior to which child_mc i clicked.
so the scenario is when I click child_mc1 which remove itself from the scene, then next I'll click the close_big movieclip to remove big_mc from the stage and will save it's own state, so then the next time i run the SWF file and dynamically add big_mc to stage, child_mc1 would be still missing and child_mc2 would still be displayed (EVEN IF I CLOSE THE SWF FILE, the state should be saved). please help..much is appreciated.
code in main time line:
var big_mc:mother_mc = new mother_mc;
add_big_btn.addEventListener(MouseEvent.CLICK, call_big);
function call_big(e:MouseEvent):void
{
addChild(big_mc);
}
the code inside big_mc:
child_mc1.addEventListener(MouseEvent.CLICK, remove_child1);
child_mc2.addEventListener(MouseEvent.CLICK, remove_child2);
close_big.addEventListener(MouseEvent.CLICK, bye);
function remove_child1(e:MouseEvent):void
{
removeChild(child_mc1);
}
function remove_child2(e:MouseEvent):void
{
removeChild(child_mc2);
}
function bye(e:MouseEvent):void
{
this.parent.removeChild(this);
}
You want to start with SharedObject, which as Adobe puts it, "is used to read and store limited amounts of data on a user's computer or on a server". To save the "state" of the MovieClip is more complicated.
What about it do you want to save? The x property? Perhaps the alpha? EVERYTHING? Each object is stored in a default state in your swf. Library items in the Flash IDE are technically miniature classes, as evidenced by the way we instantiate them. Assuming you create something called customButton, you could spawn thousands of them onscreen (or one) like this:
var foo:customButton = new customButton();
Like a hand-written class, a copy of the customButton is created with all the properties you defined on it before you compiled it. If you want to change those properties, you have to address each and every one you want different.
Looking at this broadly, let's assuming you want to save the position of your button every time you load the swf. Load with getLocal(), and save with flush().
var settings:Object = SharedObject.getLocal("foo");
function updateState(e:Event):void {
myButton.x = settings.x;
myButton.y = settings.y;
}
function saveState():void {
settings.x = myButton.x;
settings.y = myButton.y;
settings.flush();
}
It's not impossible; there's simply no push-button solution for it. If you wanted, you could write a function which iterates over all DisplayObjects, and loads/saves each relavent property from/into your SharedObject. Might be overkill, though.
I feel like something like this exists but how would I create a button in only action script 3 code? I mean without making a shape and converting it to a button symbol or something. It would probably make it easier to only work in FlashDevelop.
You can use the SimpleButton class or roll your own using the Sprite class. Then you can draw anything or use any image as the button and it's over, down and default states.
For example a simple button can be like this :
var goButton:SimpleButton = new SimpleButton();
var myButtonSprite:Sprite = new Sprite();
myButtonSprite.graphics.lineStyle(1, 0x555555);
myButtonSprite.graphics.beginFill(0xff000,1);
myButtonSprite.graphics.drawRect(0,0,200,30);
myButtonSprite.graphics.endFill();
goButton.overState = goButton.downState = goButton.upState = goButton.hitTestState = myButtonSprite;
addChild(goButton);
You can have different display objects for each state of the button or you can attach bitmaps instead of sprites.
i'm adding a movieclip element ("lastSlide") to an other movieclip element("endLogoButton"). The added element has a child which is a button("endLogoButton"). How can i call that button?
mcSlideHolder.addChild(lastSlide);
/*mcSlideHolder.getChildByName("endLogoButton").buttonMode = true;;
mcSlideHolder.getChildByName("endLogoButton").mouseChildren = false;
mcSlideHolder.getChildByName("endLogoButton").useHandCursor = true;*/
lastSlide.endLogoButton.addEventListener(MouseEvent.CLICK, linkClick);
As a beginner i'm struggling around ... but can't make it work ...
It always tells me that the access to a Nullobject reference is not possible.
Thanks for any advice!
You can either 'dig in' to the nested objects to get to the button instance or you can add event listeners to the button instance before adding it to its parent container then let its click event bubble up.
I'm having a bit of trouble understanding what is nested inside of what in your case but I see you're trying getChildByName. getChildByName only gets a direct child (not a child of a child) by its instance name, (not it's variable name).
Dig in example:
lastSlide.getChildByName("endLogoButton").addEventListener(MouseEvent.CLICK, linkClick);
or
lastSlide.name = "myLastSlide";
mcSlideHolder.getChildByName("myLastSlide").getChildByName("endLogoButton").addEventListener(MouseEvent.CLICK, linkClick);
If lastSlide were placed on the stage visually in the Flash IDE, then you could set the instance name myLastSlide there in the properties panel rather than by setting the name property in as3.
or maybe: try casting the "lastSlide" to a MovieClip like:
MovieClip(mcSlideHolder.getChildByName("lastSlide")).getChildByName("endLogoButton").addEventListener(MouseEvent.CLICK, linkClick);
This worked for me several times when the "possible unreferenced object" error popped up when referencing a movieclip that was clearly added to the stage
