AS3: Can't create Movieclip class instance?


AS3: Can't create Movieclip class instance?

wish helps you What Organis said is this: When you create a DisplayObject, for example a MovieClip which is the class that your WhiteBall extends, then the stage property of that object is null. That means that when you tried to access the stage property of your whiteball on its constructor
code :
public function WhiteBall() 
{
   stage.addEventListener(KeyboardEvent.KEY_DOWN, keysdown);
} 
public function WhiteBall() 
{
    if(stage != null)
    {
        stage.addEventListener(KeyboardEvent.KEY_DOWN, keysdown);
    }
    else
    {
       this.addEventListener(Event.ADDED_TO_STAGE, addedToStage);
    }
}
private function addedToStage(e:Event):void
{
   this.removeEventListener(Event.ADDED_TO_STAGE, addedToStage);
   stage.addEventListener(KeyboardEvent.KEY_DOWN, keysdown);
}

may help you . i'm trying to use compiled assets and code from a swc. Inside a new fla I select the swc to be included when exporting. When create the instance in the timeline of the code works and I can see assets that are inside the swc and trace a propertie from the same object. The problem is only when doing the same inside a movieclip, can't reach the assets (movieclip) but I can still trace properties from the class. , add a linkage id to tf in template

it helps some times 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? , Just use the script:
code :
placeholder.alpha = someValue;

Hope that helps Make sure that the instance of ButtonExit exists on every frame of the menu timeline and that it's instance named appropriately on every frame or write an if statement to only run your code if the Button is currently on the correct frame.
Every frame when the menu clip animates it's going to re instantiate everything on the frame, so if your second/third/fourth/etc frame doesn't have a clip named btnExit it's going to throw an error when the constructor is called for that frame.

may help you . Nothing. You can't add same MovieClip lastmc to several parents at once. From your code, lastmc will be only in mc3
If you want to iterate over children of mainmc:
code :
var i: uint, len: uint = mainmc.numChildren, movie:MovieClip;

for(i; i < len; ++i){
    movie = mainmc.getChildAt(i) as MovieClip;
    if(movie != null && movie.numChildren > 0){
        movie.getChildAt(0).visible = false;
    }
}

hop of those help? Here is the easiest (though not best) way you could do this.
On your main (root) timeline, put the following code:
code :
var weaponId:int = 1;  //never modify this directly, use the function below so the event gets dispatached. - This value will correspond to frame in your weapon movieClip that will contain the correct graphic of the selected weapon.

function changeWeapon(id:int):void {
    weaponId = id;
    this.dispatchEvent(new Event("WeaponChange")); //this will dispatch an event, so anything listening for this event will know it's been changed
}
MovieClip(root).addEventListener("WeaponChange",updateWeapon,false,0,true); //listen for when the weapon changes

updateWeapon(); //update the weapon immediately to the current value

function updateWeapon(e:Event = null):void {
    weapon.gotoAndStop(MovieClip(root).weaponId); //assuming your hand timeline has a movieClip on it called weapon and each frame of weapon corresponds to the weaponId
}
