ActionScript 3.0 :: Reusing Functions - What Movieclips The Function Should Be Applied To?
Sep 11, 2009
I somehow am able to write bits of code but am still learning how to restructure code so that it is more efficient.I have 15 buttons. Each one, when rolled over, should change the color of 2 movieclips underneath it (and when rolled out, should change back). I have the below code so far but I don't think I have to re-write the functions each time. How do I "re-use" the function code (or, only write the function code once), but specify what movieclips the function should be applied to? These are just 2 of the buttons of the 15:
Code:
menu_mc.invis1.addEventListener(MouseEvent.MOUSE_OVER, changeColor);
menu_mc.invis1.addEventListener(MouseEvent.MOUSE_OUT, changeBack);
function changeColor(event:MouseEvent):void[code].................
I have these images that will load when I input a certain string of text but I don't know how to combine functions to make a generic one that will work for all of the images. These are just two and they're basically the same thing except I have to make each function (something)1 and then (something)2 for the next image.
I'm doing a filmstrip animation and each frame of the strip has a small pic on it and using TweenLite, I'm making it expand and contract on mouse rollover and rollout. That's not the problem. Since it's basically the same function, I don't want to have to write it for all 16 frames. I thought I'd try 'this' but that doesn't work on AS3. So I'm trying to find a solution that does. Here's my code (for one frame of the movie....in this case, the eighth).:
I am trying to reuse the lines of code and it worked fine the first time but when I tried to use the evtObj.target.name it gave me error 1120:Access undefined property evtObj.Here is the code I tried to use:When I test the movies it just runs automatically instaed of waiting for the click.
I'm creating a pacman game and basically I'm having trouble coding the enemies (ghosts), the code works perfectly with just one ghost, as soon as I add another it starts to go wrong.Firstly I've got this function which places the enemies:
Code: //places the enemies function placeEnemies() {
I have some functions that when applied directly to buttons work as planned, but when I create a function from them to apply to the array, they fail to execute properly. This function is meant to set all 56 buttons to alpha 0, and as unselected. What happens is the buttons flash onscreen at 100% before setting to alpha 0. They do behave as if unselected, but don't know if that's due to the code.
This function should fade the button up on rollover. But on rollover the button only increase by 10% then stops. Each subsequent rollover increases it another 10%. Code: for (_root.i = 0;i<56;i++){ _root["btn"+_root.i].onRollOver = function() { this._alpha<100 ? this._alpha += 10 : this.onEnterFrame = ""; }}
This function should fade the button out on rollout. Since the rollover increases them only by 10% increments (above), the result is the buttons just bounce back and forth between alpha 20 and 30. Code: for (_root.i = 0;i<56;i++){ _root["btn"+_root.i].onRollOut = function() { (this._alpha>20 && this.bSelected==false) ? this._alpha -= 10 : this.onEnterFrame = ""; }}
Last one: This function should set several behaviors on release. Right now none of them appear to work. Code: for (_root.i = 0;i<56;i++){ _root["btn"+_root.i].onRelease = function() { this.bSelected = true; this.enabled = false; pastBtn.enabled = true; pastBtn._alpha = 20; pastBtn.bSelected = false; pastBtn = this; }}
i've been trying to get to grips with OOP and have so far managed to comprehend the basics of classes, methods, properties, the constructor function and property inheritance, helped by a number of examples and tutorials from the web and Moock's Actioncript - The Definitive Guide (O'Reilly). however, i've reached a sticking point when i try to apply these principles to actual movieClips. i want to attach movies from the library and control their properties using OOP, but i cannot work out how to apply the custom properties i've created to them. for example, i have a constructor Ball, with a property move, and i want to create movie clips ball1, ball2, ball3... which have properties such as radius and speed.
I'd like a movie clip called "following_cursor_mc" to follow the cursor, regardless of which of several different frames the playhead may be on. I've reproduced the code below on each frame in which I would like the cursor to be followed by "following_cursor_mc" but these errors are thrown for each of the frames:
I am setting up a flash game with seven toggle on/off buttons that all do the same thing.I know how to assign them all to be able to do the same function in the main timeline. What I can't figure out is how to get them all to also do the same function within each of their respective movie clips.
I'm trying to make a td game for fun and I need to make function to build towers and if I want to build the second tower it changes the first one... But I thought if i could change the name of the first tower's name when it builds to other var and it should be fine, but the problem is that those 2 towers will shoot together or something, so is there a way to bind functions to movieclips that are created with actionscript (addChild(Name))?
I was looking a tutorial that shows how to make modular functions, the user only used numbers, i was wandering if there is a way to use this with movieclips or childs.[code]...
I have this REALLY wierd problem. I have a MovieClip that is attached onto the stage. In this MovieClip I have the init() function. When I try and call this function, after the MovieClip has been attached on stage it doesn't work! I can't belive it!
I've not touched AS2 since AS3 appeared, but circumstances brought me back to using AS2,Is there way to invoke the functions/methods in a loaded movieclip? I know you can do that in AS3 by invoking the Loader object's content's function, but I haven't been able to do that successfully in AS2. I'm currently using the AS2 MovieClipLoader object, like so (snippet):[code]as set up, I intended the target movieclip's function 'invokeInternal Function' to run, but it doesn't seem to be doing it although the SWF itself loads successfully.
I'm trying to simply access anything inside this loaded SWF and all I get is 'null'.
I have code in the parent SWF that needs to tell the child SWF movieclip what to do but nothing works. This was a piee of cake in AS2 and I can't seem to get anything to crossover in AS3.
Here's my code:
import com.greensock.TweenMax; import flash.display.MovieClip; var myLoader:Loader = new Loader();
[Code]......
panel2 traces null and all the clips loaded within pull up undefined property errors.
I have done this same thing in ActionScript 3, but am not familiar with ActionScript 2, which I am forced to use for this project. I am loading products into a SWF via XML and attempting to add a click event to each dynamically-created movieclip. Simply tracing the text from a node in XML will do for now. I'd like to assign a property called "desc" or "description" to each movieclip and have it trace that property's value when clicked. Here is the relevant portion of my code as it stands[code]...
I have the following code, which should display some square clickable clips over a map. This is done by calling a function (shown below) with arguments. However, when I call this function, only the last box is shown... The clips are drawn on the same level (9000) but that should not be a problem as they wont overlay...functions calls....
I will have 5 type of buttons. Each type I will duplicate (+1) at some condition. Each button is sharing a same functions, just some difference in value and positions. Button type's name:bug1, bug5, bug10, bug20, bug50
I am currently having a mc in my library use a class. The mc is duplicated and put on the stage. Inside the class the mc gets a rollover state. Problem is that, although the rollover listener and function 'works', any action that is given is applied to all objects linked to that class.
Code: Select allpublic class cities extends MovieClip { private var theStage:*; public function cities(cityid:int, cityname:String, mymc, ref:*) { theStage=ref; this.alpha=.85; this.buttonMode=true; [Code] .....
So pretty much on rollover on one of the mc's makes them all alpha = 1 and rollout makes them all alpha = .85 instead of the one being rolled over. It does make sense I guess because they are all calling that same function I think. I also tried referring to the specific mc (mymc) instead of the parent and this.
Is there an easy way to animate multiple movieclips without using a lot of functions and setInterval??I want an animation to start and before it's finished another one starts, right now I'm using a ton of functions and setInterval but I'm sure there's a cleaner more efficient way to achieve this.
My setup has several movieclips in different layers. My problem is that .onRollOver, onRollOut and .onRelease functions are still active for movieclips lying underneath. Is it possible to inactivate these functions and then activate them again when it is needed? Or how do I solve this?
I'm doing a basic site with frame labels on the main timeline whose name corresponds to the btn names. A simple otoAndPlay(evt.target.name); I have a basic navigation setup of 7 mcs with mouse eventlisteners for CLICK, ROLL_OVER and ROLL_OUT.
Does anyone know a better way to do this so when my mcs are clicked they display the rollover content/art? In essence I'm trying to achieve that when the user clicks a btn it goes to that "page" and the corresponding btn stays highlighted. Pretty standard web navigation technique but I just don't know what the best way to do this in flash is and with how my site is setup.
I am making a character walk. This code will make him wobble to the right and when thats done it will trigger him to wobble to the left and then call the function again to continue the loop.I can get the loop to work fine by calling the function but how do I STOP the function? Also I want to call it later on. Is there a way to start and stop a function?
I am having a real problem with understanding something in flash - it doesn't work in the way I expect so I figure I have really misunderstood something.What I want:I am creating a bunch of .swf files and in each one I want multiple instances of an object that when you put the mouse over it the object will play its animation a bit and pop up a tool tip. Each object can look different (i.e. be a different bitmap) and animate differently (shake, pop, rotate etc).What I did:I have tried to create a class (myMouseItem) that creates the necessary listeners to handle the animation and pop up the tool tip.
I create a library item and attach it to the myMouseItem class. I can then put one instance of this inside my .fla and it works. (I still seem to have to put a .stop() in the actionscript for the scene to get it to stop animating for ever but I can probably live with that)What I can't figure out:How do I repeat this with multiple objects all with different bitmaps but reusing the underlying class? When I try to add another instance of my library class and edit the bmp it changes all instances. When I try to create another library item with the same underlying base class I get an error saying that I have to choose a unique identifier, so I don't seem to be able to reuse my .as file.
I am trying to reduce the size of my swf, and I see that I am using a movieclip on each frame on the Timeline, which has to be adding considerable size to my file, since I have placed the movieclip(animation) on every frame. How could I do this more efficiently and still acchieve animation between each frame? I have included a ripped version of the fla. , since the attachment limit here is pretty low. In the file the video - files and the picture files have been removed, but the rotate... mc's(animation) are placed in the interanim Layer and the Menustate Layer, on each frame.
I am doing a web portfolio with thumbnail buttons that change the pictures. What is the best way to avoid having to make a new button for each new picture thumbnail? So resusing the button but changing the thumbnail picture in it and what picture it links to? Using CS4.
Suppose I want to load a .jpg from the server ONCE and then I want to reuse it a dozen times in my .swf... How can I achieve this without adding to the .swf`s file size? I was thinking copying its BitmapData a dozen times, but that adds to the file size, right?
I am making a mobile application in as3. I'm optimizing.I have a scroll containing 30 objects (buttons). All buttons are the same except its title.This bucle is inside the container scroll:
for(var a:int=0; a<global.get_A.get_B.length; a++) { b = new ItemList(global.get_A.get_B[a]);[code].....
Out of some curiosity and the use of possible standard key variables so I don't have to create several instances to the same class, I was trying the following:
[Code]...
My question is: Is there a better approach to this on AS3? Something tells me I'm just heading the wrong way there...
