ActionScript 3.0 :: Referencing An Object That Exists Later In The Timeline?
Jul 7, 2010
I'm trying to:Jump from frame 1 to a frame later in the main timeline Reference an object that exists on the stage in that frame, but not in frame 1
Like so:
ActionScript Code:
function endGame():void {
gotoAndPlay("gameOver");
scoreField.visible = false;
}
A movieclip with the instance name 'scorefield' exists in the "gameOver" frame, yet for some reason, I just get a "Cannot access a property or method of a null object reference." This code is all within a function. By the time the reference to scoreField is executed, the timeline is at the right frame.

This must have been done before and be really easy but I am a newbie so just keep coming up with compiler errors. I have built a website in flash cs4 using as3. I have set up the time line so that each different page on the website exists at a different position on the timeline. Sections have been labeled so that I can jump to that section upon button click.
What happens is when the link to the page/section is clicked the timeline jumps to that section and plays an animation that animates the page onto the stage then stops.("in animation") When you click another link the page should animate off of the stage ("out animation")and the next one animates in.
(I have set the time line up so that after each "in" animation there is a stop and after each "out" animation there is a stop.) This is where i'm having the problem.
I have set up event listeners for the button clicks But i can only get them to either play the "out" animation then that stops, using this code:
[Code]...
What i would like to know is how to add the two together so that when a button is clicked the information about what was clicked is added to a variable. The function plays the out animation then when that is complete checks the variable where the page clicked information is then jumps to that section on the timeline and plays it's "in" animation

I can import other classes to the timeline and use them just fine, but this class is giving me major problems? I am parsing XML data from my server on it and it is giving me errors that look like this.
The timeline reference and usage:
import networkScores;
var network:networkScores = new networkScores();
addChild(network);
score1Textfield.text = network.score1.toString();
[Code] .....
The errors I am getting:
Scene 1, Layer 'Actions', Frame 4, Line 149 1119: Access of possibly undefined property score1 through a reference with static type networkScores.
1067: Implicit coercion of a value of type networkScores to an unrelated type flash.display:DisplayObject.

I have a root timeline in which contains a movie clip on a certain frame. Inside that movieclip, on it's second frame, there is a button. I would like to use this button, when clicked, to move take the user to a frame on the root timeline.

i just wanted to know if its possible to reference a different levels timeline. I want to create transitions in my site when loading dynamic content. I looked at the tutorial but it specifiacally relates to loading movies into movie clips. In my site i am already loading movies into levels.
I have my navigation on the main timeline (level 0) and im loading and unloading each sections content into level 1. Is it possible to load a movie on level 2 with a mask and preloader that will cover the content being loaded into level 1?

I have a 13 movieclips within another movieclip which in turn is placed on the root timeline. I have written a function in the actions layer of the main timeline:
function illboxClear(){
_root.illpre.ill1.gotoAndStop(1);
_root.illpre.ill2.gotoAndStop(1);
_root.illpre.ill3.gotoAndStop(1);
_root.illpre.ill4.gotoAndStop(1);
[Code] .....
It sends the animation in each of those described movieclips back to frame one as you can see. When I try to call the function from actions on a button which itself within a separate movieclip placed on the stage:
on (rollOver) {
illboxClear();
_root.illpre.ill2.play()
} on (rollOut) {
_root.illpre.ill2.play()
} on (release) {getURL("boxer.html","_blank");
}
It doesn't work! Can I not call functions from button objects or have I made some other elementary error?

In my script I create a button that when clicked, creates a blue square. However, I want to remove any blue squares that exist before creating the new square (because as it is a low opacity square creating another one will make it more solid, as well it's just more objects that the system has to keep track of).Here is my code:.as

I have strange problem. I remove sprite object from container and its not visible anymore but still behaves like its existing. here is how i add object to container:
[Code]...
I think that all listeners and vars has been removed from the object but probably not because GC does not remove the object comepletly. Why object is still at its place ? Is there easy way to check what has to be removed from object so GC can collect it?

I'm trying to check to see if an object exists by using a simple if statement.
if (object.name) {
//Do this
}
However, if the object doesn't exist, I get this error, "Error #1010: A term is undefined and has no properties" - which I understand is because the object doesn't exist. Is there a better way to check to see if an object exists?

I'm attempting to make a platform game. Each level is contained within it's own MovieClip, which has it's own class. Each of these classes extend the Level class, which provides basic functionality for all levels.
Each individual level has a numPlatforms variable which stores the number of platforms in that particular level. I currently have a for loop that runs from 1-numPlatforms and sets the level area (the image, more or less) the platform contains:

Is there any way to check if a variable exists within a MoveClip? I've trying comparing it to null and also to undefined, but neither works.

I'm loading an external SWF("slides.swf") into a AS3 UILoader component on the main stage with an instance name of "loadWindow" when the user clicks a button.I'm also monitoring "slides.swf" loading with preloader script. When the movie in the UILoader is completely loaded, I want to advance it (the movie within the UILoader) to the next frame. In AS2 it was easy to reference a swf loaded into a movie clip... the nested movie's root took the place of the MC's timeline.

I am trying to avoid this error:TypeError: Error #1010: A term is undefined and has no properties.It is being caused when I reference an object that does not exist. My code automically goes through an array of objects and will sometimes try to reference a location that does not exist (like [-1][6] for example).I am trying to set a variable based on another variable from an object in that array like so:ob.upleft = Map.baseTileArr[ob.upY][ob.leftX].walkable;If it does not exist, my program stops and I am thrown that error. My question is, how can I check to see if that object's variable in the array even exists before assigning the variable?
I've tried this, but it did not work:
if(Map.baseTileArr[ob.upY][ob.leftX]){
ob.upleft = Map.baseTileArr[ob.upY][ob.leftX].walkable;

I have a weird problem. An Object is being passed to my function, and some parameters are optional, so naturally I would check to see if they are there, and if not, do nothing.However, I'm getting a null reference error (#1009) when I'm just checking it. Here's the sample:

How do you reference and already existing object in as3? My below program draws 2 circles and a line to connect the two. The circles and the line are all individual objects. The line (connector class) has a function called update that should redraw the line between the two circles. It has two variables which I want to be the references to the two circles. The circles (coolcircle class) has a variable which I want to be the reference to the connector. It doesn't seem like my update() function is getting called.

I have an object present in frame 3 of the main timeline. When the object was present in frame 1 i could access it from an as3 code file. But when I am keeping the object in frame 3 of the timeline (Please note that the previous frames for that layer is blank). I am getting a null value for the object. if I try to use trace the object.Logically if I am in frame 3 i should be able to access it.

I need to know how to call or reference (not sure of the terminology) an object by way of a string. What I'm trying to do is create a loop that will add event listeners to objects named "portfolio1" through "portfolio15", and use a function.[code]If I could just reference these fricken objects through a string and an integer, I could set up a small loop like this to make the button "portfolio1" bring up a big jpeg of "bigportfolio_1", and "portfolio2" bring up a big jpeg of "bigportfolio_2", ext. While yes, I could just go through them all and set up event listeners to each one individually, but its REALLY inefficient. Also, I am still working on more advanced actions (like scrolling through the portfolio pics chronologically) that absolutely requires a different reference method.

I have my main flash, named "front page". Inside of it, I have 2 movie objects that have a time line, one named "About Us", and another named "Button Group". Inside of "Button Group," I've made a drop down menu that can go to a frame on the main page (in "front page") using the _root command. I was wondering if I could go from the front page into the other movie object ("About Us") by going through the main page.
Tl;dr, I'd like to know how to go to the parent of a movie clip and into another movie clip to modify where the time line is.
