ActionScript 3.0 :: RemoveChild() And Cleaning Up Objects Properly?
Jun 26, 2011
I'm a relatively experienced programmer, but I'm completely new to as3my question is how can I remove one object and subsequently all it's child objects and their listeners?I need to remove all objects from a certain object called "world". My objects are all on top of this "world" object. the game has a level object which is on top of this "world" object and it produces enemies among other things on an enter frame event.To remove this from the stage I call the world.destroy() method from the main timeline.
Code:
// * Destroy the world
public function destroy()
if you have object inside of object inside of object ... etcwhen you want to completely remove it is it enough to just say:removeChild(topObject);or you need to go inside and start cleaning from there?
I got on stage a bunch of squares (sprites), so when the browser change size, I need to re-draw this squares and re-calculate max numbers of that can fit on the page, and so on..., my issue is I call three functions in the resizeListener
I have a stage that's filled with dynamically generated isometric objects [ in the shape of a smiley, placed according to an array ], and when I click a button, I would like the stage to be cleared, then another frame with another isometric code and another array to load. The problem I am facing now is that the items positioned from the smiley are still on the stage if the next array is smaller than the previous one. Any way I could clear the stage before going on the next frame? Currently, I tried unloadMovieNum(depth) in between with this code:
Code: n = 50; onEnterFrame = function(){ trace(n); n--; unloadMovieNum(n); if ( n<=0){ nextFrame(); } else { stop(); } } What happens is that it clears the stage, but doesn't load anything in the following frame.
I've condensed my problem to the code/situation below for testing purposes. I have several MCs. At any point, any one of them may be on the stage (via various other user interaction throughout the project - I've cut out all that for simplicities sake). I need a way to, at the press of a button, remove (from the stage) whichever MC happens to be there at the time. My hope was to put them all in an Array (or some other container??) up front, and then make code that would remove any of its current objects on command. Am I barking up the wrong tree?Here is the code. For testing purposes, I'm assuming that only one of the MCs ("b") have been added to the stage at this time:
var aroject1 = new project1(); var broject2 = new project2(); var croject3 = new project3();
I'd like to remove objects via removeChild after Tweenlite has finished tweening. But it doesn't really work because my objects are still in the DisplayList.
Code:
//TweenLite.to(sndText, .5, {alpha:0, onComplete:removeChild, onCompleteParams:[sndText]});//does not really work; still in DisplayList TweenLite.to(sndText, .5, {alpha:0}); TweenLite.to(musicText, .5, {alpha:0}); TweenLite.to(sndSlider, .5, {alpha:0});
I am making sims like game and right now I am trying to figure out how I will structure my objects. right now I am thinking to create a class called GameObject, the psuedo is below
public class GameObject { name:String width:int height:int }
This way I could create objects like bushes, trees, and buildings. But then I began to think. what if I wanted to create multiple buildings and trees of the same type ?? I would have to keep making instances of GameObject and giving it a new name and height and width. The properties would have to be the same values in order for me to duplicate one object. That seems a little tedious. Then I figure , maybe that isnt the right way to go. So I was thinking, I would have to extend GameObject like below
public class Tree extends GameObject{ birdHouse:Boolean } public class Building extends GameObject{
[code].....
Now this way I can create a class that has a method that loosely accept accepts any type that inherits GameObject.
Selector.loadObject(gObject:IGameObject);
Depending on what type it is (i.e tree, building, house) I can use a case statement to figure out which type it is and evaluate it accordingly.
I also created a Tile Class that will pass through the loadObject method. It also will be a child of the GameOject class. if the case statement finds that it is type Tile, it will highlight whatever Tile depending on what tile my mouse is over.
My second question is if a class inherits a class that implements a interface, is that class child class considered to be a IGameObject as well. or does it have to implement that interface directly. does all this sound like I am going in the right directions lol, as far as organization is concerned.
This is unfortunately a quite complex issue to explain, so please don't get discouraged by the wall of text - it's there for a reason. i'm working on a transformation manager for flash, written with Actionscript 3. Users can place objects on the screen, for example a rectangle.
This rectangle can then be selected and transformed: move, scale or rotate. Because flash by default rotates around the top left point of the object, and I want it to rotate around the center, I created a wrapper setup for each display object (eg. a rectangle).
[Code]...
Now, to the question: should I use a different kind of setup, system or structure? Should I maybe use matrixes, if so, how would you keep a static width/height after rotation? Or how do I fix my current wrapper system for scaling after rotation?
var myObj:Object = new Object(); myObj["someProperty"] = { anotherProperty: "someValue", whateverProperty: "anotherValue" }
now i want to send it to a web server (rails):
var service:HTTPService = new HTTPService(); service.url = "http://server.com/some/path/entry.json"; service.method = URLRequestMethod.POST; service.send( myObj );
the problem is that the server receives the json like this:
{"someProperty"=>"[object Object]"}
is this a problem with HTTPService? should i use the good old loader/urlrequest and serialize myself? by the way, serializing and then passing the string doesn't work, webserver receives empty request as GET.but i kinda want to use the httpservice class though...
I'm trying to build a conditional statement that will addChild and removeChild at different Timer Delays. Before I go any further, I thought, I should mention that I'm usinig TweenMax to ease the alpha of ease Child from 1 to 0 and back during the process to imitate a fade-in/out.
I'm getting issue with only one line - inside a conditional statement.It's running "OK". The movie runs as I want it, but the remove/addChild transitions are not at the speed I want it at. I am getting an error message in the output, but other than that, the movie runs fine.
I have a stage that's filled with dynamically generated isometric objects [ in the shape of a smiley, placed according to an array ], and when i click a button, i would like the stage to be cleared, then another frame with another isometric code and another array to load.The problem i am facing now is that the items positionned from the smiley are still on the stage if the next array is smaller than the previous one.Currenlty, i triedunloadMovieNum(depth) in between with this code:
I've created a map with the 50 states. I then hardcoded this so that when you hover over them the alpha is set to .5, and if you click on when it's ChildIndex is set to -1 and it plays the animation of the state growing to full size. I know there is a better way to do this, rather than how I wrote each line of code for each of the fifty states...
I'm also trying to play an outro animation "down" after the state is clicked while it is enlarged from the "up" animation.I also tried to create a var state so that when you mouse off of a state the state is no longer highlighted, but I ended up doing a work around using currentframe=.
Code: //import flash.events.MouseEvent; var small:int = 1; var big:int = 2;[code]....
I'm trying to clean up my code for an animation I created. I'm hoping by doing this, my animation will stop being as buggy and/or I can more easily figure out why its being buggy. think that variables are the way to go so I read up on them and have a decent idea of what I need to do. But what sounds good in my head doesn't seem to work on screen.So basically I would like to take my three buttons called card1, card2 and card3 and combine their functions. All the code for each button looks exactly like the code below (except for the mc name of course)
Code: card1.addEventListener(MouseEvent.ROLL_OVER, overhandler); function overhandler(event:MouseEvent):void {
The reason why I'm writting it's because I'm doing a website in Flash, and I don't know how to do one thing.I can create the TextArea, it's ok by now. But what I want to do now it's create 2 buttons. In the first, the "Clean" button, if I clicked on him, the TextArea delete everything it was written there, and in the "Send" button I send an e-mail to one e-mail, with what was written in the TextArea.
I had Flash 8 on my computer, and back when CS3 came out I purchased the full suite and installed that. Yesterday (years later, now) I was cleaning up installs on my computer to free space. I used Control Panel to remove Flash 8 from my PC.Now Flash CS3 still launches and works, but I cannot get .swf files to launch on their own at all. When I double-click them to open them, I get the message:
The file does not have a program associated with it for performing this action. Create an association in the Folder Options control panel. I've googled to figure out what that means or how to do it, but I haven't found a decent reply that's been effective. If I try to drag a .swf into a browser window (or just open it with a browser), it is also not recognized. Oddly enough, I can view Flash files on web pages no problem (when browsing online)...
Some necessary components must have been removed when Flash 8 was installed. I suppose I could try re-installing Flash CS3, but the problem with that is that I'm out of town on business for the next 10 days. My Studio install discs are back at home, and I need to get work done this week!.
Lets say a scene started off around 70-80mb, it loaded a swf in, and by removing the event listener and setting objects to null and numbers to 0 before unloading the swf,and went back to the original scene, the memory stack up till like 80mb++, and every time I repeats the same process the memory goes up higher,is that normal? or its a memory leaking issue?
As a best practice should trace statements be removed form all AS once we're on the final files? Or does it not matter and therefore best for future reference to leave them be?
I have a working rotating menu that I have been changing to suite what I am trying to acheive. it all works apart from the distance between images which I can sort out later. At the moment the movie has a UI which I would rather remove including the script that makes it function just leaving the rotating menu, and the script to change the radius and size etc witin the main.as. I do not want the user to have the capabilities of the UI control panel. remove and clean up the script as everytime I remove related script the menu stops playing. I have uploaded files to here: [URL]
I want to display HTML formatted content from various sources inside a Flash Flex application. Flash supports HTML formatting in its text fields, however it is very limited compared to a web browser. Are there any scripts out there that will convert common HTML formatted text into a format that Flash can handle? My particular use cases are:Displaying HTML formatted emails inside FlashDisplaying RTF files inside Flash (after running an RTF2HTML conversion on the server)Displaying random HTML content copied and pasted from other sources into Flash
I have a bit of code that calls a custom class that I made in flash. Basically when you roll over this logo I have a function that makes a new instance of a custom class and calls it to the stage like a little pop-up text when you roll over something. Then when you roll off of it I remove it from the stage. The following code is for the first pop-up text.
I have made a game that after you reached a certain object it will switch to the next level. The next level is in a new layer and in a new frame. Problem is I think all of the properties (speed, collions etc..) have been inherited... Meaning my charachter will move on his own and collisions will still apply for objects if the previus frame.
Is there some kind of way to clean all of the properties and have "fresh" start? I have tried to clean the Array that detects the collisions, the collisions work now. But the player now is 2x faster and also jumps 2x higher... I don't have the code to past in here right know, I will add it later. So, summing up. Is there some kind of way for me to clean the properties of objects from one frame to the other?
I'm trying to do a cleaning of some classes that is added into a MovieClip, but I can't seems to set the MovieClip(Class) to null. What is the proper way to do it?
private var mcHolder:MovieClip = new MovieClip()[code].................
I've created a MovieClip that opens other MovieClips. These MovieClips are galleries with example of my art and such. Within these gallery MovieClips there is a "close" button, which is actually another MovieClip.
the problem
Everything works except that when I open one gallery, then close it, then open it a second time, the "close" button refuses to work.
I thought this was do to my incorrect use of removeChild, but now I don't know.
This is made slightly tougher by the fact that closing the gallery involves playing a closing animation, so first I put the removeChild on the last frame of the gallery MovieClip. That had the same result so then I tried it this way.[code]...
Internally Flash obviously keeps a list of the primitives drawn using Graphics so I wondered if you have many such primitives in a Sprite, can you re-position/remove/alter individual items rather than clear and re-draw everything? Or is this deeper into the bowels of Flash than you're allowed (or recommended) to go?
I'm using Zend AMF to send my remote objects to Flex. I've defined a Constant class and created getASClassName() method. Then I've created Action script class in flex.
Objects are send successfully, but they are deserialized to generic Objects in Flex instead of specific ones. EDIT: On network monitor in Flex I can see that AMF value is set to com.my.project.valueobjects.Constant. Although array from event.result contains Objects.
I have an array of temporary objects created in a for loop. The objects are of type class "Tile", a class I created. However, it appears that whenever I create a lot of tiles in the for loop, the program slows down indefinitely.
While the array is whiped at a later trigger point, I am thinking that perhaps these Tile objects are not being erased from memory. They are being created on the fly in a for loop, and the array is being reset to "array = []".
Are the objects still in memory or are they cleaned up when the array is set to []?
What I have is a game with a Level object, inside the Level is a Player object, and they don't have instance names given, what I'm trying to figure out is how to do is make it so that the player can change the x or y properties of the Level object.
To be more precise, I'm making it so that when the player moves in a certain direction, he either moves accross the stage, or he starts moving the Level object around the stage, it'd be in an Event kind of function, now I can easily make the Player move, but I don't know how to make the Level object move which the player is inside of.
