ActionScript 3.0 :: Removing And Adding MovieClips To/from Arrays Based On A Variable?
May 8, 2009
On my stage I have 5 items labeled item1_mc, item2_mc, item3_mc and so forth...they all have two keyframes on their respective timelines, one labeled "active" and the other "inactive". My code contains 2 arrays, inactiveArray and activeArray and a variable known as energy that regularly goes to and from 0 - 100.What I am looking to achieve is basically the function of...if energy >= "insert given items 'active threshold' 20, 40, 60, etc..." then add it to the activeArray, if it is not, remove it and add it to the inactive array.
all objects in activeArray gotoAndStop("active");
all objects in inactiveArray gotoAndStop("inactive");
I have tried many different ways of achieving this effect but I always end up with duplicates and extras or something doesn't move when it's supposed to, where it's supposed to, it just ends up into a giant cluttered mess and I start from scratch.
So a small example of my situation...On my stage I have 5 items labeled item1_mc, item2_mc, item3_mc and so forth...they all have two keyframes on their respective timelines, one labeled "active" and the other "inactive".

I have a game where i add some cartoonish ants, that when they are clicked, they need to be removed from stage. There are 4 differend kinds of ants, so im doing a Math.random for picking which one to add. (ant 1+2+3 have 50% chance to spawn and 4th 50%) rnd_nbr = (Math.random() * 5)+1;
I have a timer doing 10 tick, and i reset the timer to make neverending. Then i have a math random and if sentences adding mc' to the stage with movement from Tweener, and event listeners for clicks. But i cant figure out how to remove them when clicked. I have done alot of failed tries right inside the click_candy_anty function. I've left them commented out.
I'm writing a game with Flash CS5/AS 3.0 that tries to simulate depth of field by drawing all the relevant Movie Clips based on their Y position in ascending order, i.e. things lower on the stage overlap things higher on the stage. A MovieClip with a Y position of 10 would therefore need to have a lower index compared to a MovieClip with a Y position of 20, so the second one gets drawn on top of the first.
I wrote a quick and dirty function just to test this. During the trace, I've noticed that the truck's index hits 0 when I go near the top of the stage, but if I go too far up it will completely disappear from the stage. Trace then starts generating this error:
ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller. at flash.display::DisplayObjectContainer/getChildIndex() at EICT::Game/ReorganizeDisplayIndexes()
I have here 2 options here of adding movieclips to a container, but I don't know which one is better. I want to know the pros and cons of each one. Also, What of the options is faster?. (i mean, which one uses less processor and memory resources?.
Option 1. Code: Select allvar container:MovieClip = new MovieClip(); stage.addChild(container); for (var i:int=0;i<10;i++){ var tank:Tank = new Tank(); //Tank is a movieclip in the library. container.addChild(tank); } MovieClip(container.getChildAt(2)).visible = false;
Option 2. Code: Select allvar container:Array = new Array(); for (var i:int=0;i<10;i++){ container.push(new Tank()); //Tank is a movieclip in the library. stage.addChild(container[i]); } container[2].visible = false;
My favorite error: ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller.at flash.display:isplayObjectContainer/removeChild()
What I am trying to do is basically get my navigation working correctly. I had it working by altering the alphas of movieClips, but they just end up overlapping each other even if they are invisible so that's not working out. I have 5 navigation pages. And thus, 5 nav buttons, and 5 movieClips (content for each page -- Home, Location, Tenants, Design, Contact). I want to simply show the home movieclip when on the home page and remove the movieclips from the stage for the other 4 pages.
Then, logically, I want to click the Tenants page, which removes the home page, location, design, and contact movieclips. Very straightforward show only one and remove the rest from the stage, but every combination of add/removeChild and parent and stage etc. is giving me that error above. What's confusing me the most is that the add and removeChild works for the location page, but none of the others. The location movieClip is no different than the others, and I made the code the same but it's the only one that works.
I'd like to add event listeners to movieclips (already on the stage), whose names are called from an array one by one, into a for loop.
Code: // there are 4 movielcips on the stage with name a1 - a4. // create array var Bro:Array = ["a1","a2","a3","a4"]; // for loop for ( var i:Number = 0; i < 4; i++) { // Add event listener to array values to buttons. Bro[i].addEventListener(MouseEvent.ROLL_OVER, roll, false, 0, true); //execute this function on rollover function roll() { trace("why wont my arrays work in for loops"); }}
I've created a drop down list and populated it with dynamic buttons. (I made a DropDown_btn class with a dynamic text field in it and then filled the button text from an xml file). On rollover I tint the button blue and then set the tint back to black on rollout. When you click on the button I'd like it to stay blue until a different button is clicked.
...and then I need to addEventListeners back to any button that doesn't have them and set that button back to black. I could do this by looping through an array of the buttons but I can't figure out how to access them as objects.
I also gave them each a property of "buttonValue" when I loaded them so I can access event.currentTarget.buttonValue (which in this case is a number from 1-5) but once again I can't figure out how I might leverage this information.
So basically I've got a MovieClip called Jug and when the egg is clicked and dragged to the Jug I want it to disappear and then re-add itself in the place it first started. Aswell as this I want a variable to be added by 1 in value. I have tried fiddling around with this for a while now and I can't figure it out since when I remove child it gets errors. Here's the code:
The portal in my game is suppose to be unlocked after you collect all the coins. The portal is locked but when I go over a coin it neither adds to the variable or removes the movie clip by instance name of coin1 coin2 and coin 3.also if the remove movie clip doesnt need _root I've already tried it without it I know that is not the problem.
var openportal = 0; function moveStuff() { //-Very long code that is working. [code]..........
I am running into some trouble adding an array into another array to create a multi-dimensional array.The code appears as below:
var slideDataArray:Array = new Array(); var slideShowDataArray:Array = new Array(); slideDataArray[0] = xmlData.SlideShowParameters.SlideShowImagesDirectory;[code]........
I am looking for a means of placing the slideDataArray into a 'slot' or value of slideShowDataArray so that I can in the end pass the slideShowDataArray as a parameter to another function.As of now, the last slideDataArray appears 11 times (the loop runs 11 times) in slideShowDataArray and the way the code is written the slideDataArray is unique every iteration of the loop.
After solving my previous problem I have encountered another.Basically I have 3 things moving around in it and when they hit other items they have different reactions to different numbers.hen the number 5s hit the number 2 I want them to be changed into a number 0. I have tried a few things including removeChild but I get an error that its not referenced.
I am generating lots of arrays in a for loop again and again.It it possible to delete these subArrays from the mainArray so that they dont exist any more?
Code: var mainArray:Array = new Array(); for (var i:int = 0; i< columns; i++) { var subArray:Array = new Array();[code]....
I forgot to write:I am pushing movieClips into these subArray in this same for loop and later on, I am removing these movieClips from subArrays, but these subArrays (after being cleaned) still remain in mainArray, dont they?
I can find plenty of ways to remove duplicates with literal datatypes, and I guess at an absolute pinch I could use toString and adopt one of those, but there surely must be a better way of doing this?
I'm loading an xml and creating thumb buttons from it. I loop through the xml list and add thumb clips to a container clip and add the loaders as children to the thumb clips. I store the loaders and thumbs in arrays. When I need to remove the thumb clips, do I just remove the thumb clips? Or do I need to unload the loaders first, then remove the thumbs?
I've got an array of coins, which are called within the array coin1, coin2, coin3, coin4 etc. I'm trying to reference them to say if the character hits coin 2, then coin2 will disappear. Here's my array (so far): ActionScript Code: var coinArray:Array = [coin1, coin2]; //an array which contains all of the coins
And here's the script I'm working on: ActionScript Code: function coinCollect(evt:Event){ if (collisionTest (character, coin/*[n]*/){ var i:int = /*the number from coin[n]*/ - 1 remove coinArray[i] }}
But I'm missing some major things, mainly how to reference which coin has been hit, and how to take the number from that coin and take 1 from it to reference it's correct position in the array? (the code in /* */ tags represents things I'm not sure on the code of).
Question 1Whats a good example of removing objects from stage that aren't within the stages boundries. I first tryed using a transparent box and hittesting. then i realized that you cannot hittest an object that isn't on stage, to check if needs added. so i came up with this.
Code: for (nn=-1; nn<2;++nn){ if (this.hu1.room+nn>=0 && this.hu1.room+nn<this.walls.ar.length){ for each (n in this.walls.ar[hu1.room+nn].ar){[code]....
That way it only adds the object if its not currently on the display list or am i better off just giving all objects an onscreen:Boolean variable?
Lets say I have an array which has n dimensions. Now in order to access a slot you typically use: array [1][0]What if the number of dimensions are not known at compile-time, is there an easy access like:
slot = "1,0" array [slot] // accessing 1,0 Which means I can also easily navigate back and forth
on my main timeline there is a movieclip ("sampleMc") which contains a number of labeled frames containing movieclips of gallery images (for example "dyerBikiniMc"). in turn, each of THESE movieclips contain a number of frames of detail shots of the main image (for example "dyerBikini00Mc, dyerBikini01Mc, dyerBikini02Mc, etc.").on the main timeline i have a gallery navigation bar with thumbnail buttons determining which image will be displayed. there's also a right arrow shaped button "detailsBtn" that i'd like to allow the user to click frame-by-frame through the detail shots of the image. i also have a before/after toggle button on the main timeline that needs to control the movieclip one level below that, where the before/after images of that particular detail shot are stored!
I have a multidimensional array based data and i'm pretty confused in bringing it to simple linear array. I know it requires some for in loop to set property and its value and some nested looping but i lost in the half way.
navigating to specific frames from different scenes that are elements of an array. I have a five scene program (Homepage, Chapter_1, Chapter_2, etc.). Each of these scenes includes labelled frames.For scene Chapter_1 has 20 frames labelled chap1_1, chap1_2, chap1_3, etc.
I have a list of buttons that each load an external SWF when pressed. When a button is pressed, the SWF loads into a movieclip on the main timeline, and the list dissappears (so only one is loaded at a time). The main timeline moves to a frame with a back button. When the back button is pressed, I'm trying to remove the loaded SWF and make the menu visible again to load another SWF.This all works, but when I get back to the menu and try to load a new SWF, I get the error:TypeError: Error #1009: Cannot access a property or method of a null object reference.at CrystalBall/PL_LOADING()rystalBall being the first SWF I tried to load. The error fires like, four or five times too. I know it has something to do with the code trying to remove the loader before it loads it again, but I'm not sure how to fix it
I am pretty new to actionscript 3. I want to remove the movieclip on the stage and add a new movieclip but the button is within the currently running movieclip that I want removed. I am trying this function
homeArtist_btn.addEventListener(MouseEvent.CLICK, newArtist); function newArtist(e:MouseEvent):void{ removeChild(homeAni_mc); addChild(artistAni_mc);} I get these errors
the problem occurs when I remove the button, the button has been exported for actionscript, when I remove the button to change the page/page layout, when I return to the page, the button remains in its "over" state.so im wondering if there is a way to reset it either before its removed or when its added.I cannot use gotoAndStop(1);because I am working in a package file.
I have a bunch of movieclips called firstNameBtn_mc, lastNameBtn_mc and many others. I also have a bunch of movieclips whose names start with the same but instead of "Btn" they have "Arrow", like firstNameArrow_mc, lastNameArrow_mc etc.
What I want is when I click on firstNameBtn_mc it does somthing to firstNameArrow_mc, but there are so many buttons I would like to do it in the following way.
1. get the movie clip's name...something with e.currentTarget.name for example
I'm making a banner rotator that reads image urls from an xml file and adds them to a sprite on the stage, then tweens them into position. Here's the relevant code:
I am trying to find the sum of one column's timings which is like '00:00:00' format. I am splitting the time string at ':' and storing into an array. Then trying to add array1[1] value to array2[1] value. Here I'm not getting type casting logic. I'm getting an error when I give int(array2[1]) += int(array1[1]) .
How can I make an array that accepts only a single kind of element?For example, this:var arr:Array of MovieClip = [ mc1 , mc2 ];Basically, I want to do something like this:for ( var i:Number = 0; i<arr.lenght; i++ ) arr[i].alpha = 0.5;Of course, I could to it manually, but that's ugly, and I'll have to add a bunch of "if"s if I want to access the next element (as "if ( element == mc1 ) mc2.alpha = 0.5;")
I'm trying to create something (which has probably been created a 1000 times before) that will fade in and out a series of images. I load the images into my movie and then I want to make some action script to loop through them to fadeIn/Out.So to begin with I want to store all the image names in an array and then loop through this. But I'm having problems accessing the movie clips from the array. Where am I going wrong?
Code: var images:Array = new Array(); images = [wine_mc, sunset_mc, poppies_mc, pool_mc, eastView_mc]
i have an array of movieclips that are only in the libray:
///////////////////////////////////////////////// var aeropuertosInfo:Array=new Array (iacapulco,iaguascalientes,icampeche,icancun,idf,i carmen,ijuarez,iobregon,ivictoria, ichetumal,ichihuahua,icozumel,iculiacan,idurango,i guadalajara,iguanajuato,iguaymas, ihermosillo,ihuatulco,iixtapa,ilapaz,iloreto,imoch is,imanzanillo,imatamoros,imazatlan,
[code].....
when i try to place them in the scene, for example: addChild (aeropuertosInfo[2]) , an error pops up telling me that it can't convert icampeche$ in flash.display.DisplayObject.
