ActionScript 3.0 :: Increasing Idle CPU Usage When Removing/re-creating Heavily Animated Movie Clips?
Dec 8, 2010
I've developed a touch screen flash application for a sneakers (shoe) shop. It has a 'find a shoe' section, which isn't causing problems, and an 'about' section, which is.The about section is a heavily animated history of sneaker culture. It's animated via the timeline, not via AS3. The problem is that with prolonged use of the about section, idle CPU usage grows, and memory usage grows, eventually making the app unusably slow.
I've made a 'minified' app that does nothing other than create/delete 50 instances of my 'about' movie clip - it doesn't even add those instances to the stage. I've cut basically all code out of the 'about' class, which is shown below:

I'm developing a touch-screen Flash application for a shoe store, and it runs fine initially, but slows down toward the end of the day. I've been diligent with removing event listeners and so on. I've now narrowed the problem to be very specific - it's one section of the application causing the problem, and one part of that section:
- I have a main movie clip which contains the animation, which itself contains 5 nested movie clips, each with their own timeline. All movie clips have a stop action on the final frame. images are transparent PNGs with outer glow "filter" - the issue is not with performance as such, but with CPU increasing over time. Each time you play the clip, there is a small amount of CPU usage that 'sticks' and doesn't get freed up. What happens is that if you play the movie clip many (MANY MANY) times, then eventually it starts to slow down. Mac's Activity Monitor shows that the idle CPU usage is increasing slowly, over many times of playing the clip. It's insignificant with each play, but adds up over time.
You may be inclined to say: oh filters effect CPU, so it will be slow - but it isn't slow until it plays many, many times. Initially it's fast. I've uploaded a .zip with .app and .exe versions of my problem section. There are two files of each type: AutoPlay.app (& .exe): plays the problem clip repeatedly (I've just removed the final 'stop();' frame), so you can leave it open and come back in half an hour to see it slowing down.
ClickToPlay.app (& .exe): Plays the problem clip once when you click the 'play' button, so you can click several times, let it return to idle, and verify that the idle CPU usage is in fact increasing.

I've hacked together this prototype "bouncing ball" from a few tutorials online.When the user clicks a color choice, the bouncing ball changes to the color picked. The ball does in fact change to the color, however, the animation ends.Is it possible to dynamically change the color and maintain the animation? 'm using AS3 and here is my script and no errors are thrown, so its doing what its suppose to.
ActionScript Code:
//call function changeColor on button click
//this function uses the AS color class called colorTansform

I am currently using an onEnterFrame to animate a filter which is being applied to several different animated movie clips. This filter is triggered by an onRollover, which also pauses the main movie clip (that doesn't have a filter applied to it).
The problem is, the main movie clip in the background pauses but the layer that has the filter attached (and holds the movie clips that need to be affected by this filter) isn't pausing.
So, it's going:
onRollover
Pause movie (which has an embedded flv)
OnEnterFrame filter animation
I want it to pause all the movies on the current fram and then apply the animated filter.
I've tried adding a goToAndStop but this doesn't seem to work.

i tried following a tutorial to create an animated button. it's not functioning i originally had the animation in frames and it worked somewhat. if you test the links_1.swf, it functions as i had hoped but if you activate the button quickly, the timing gets messed up and the animation sticks. file:///Users/GS2/Desktop/links_1.fla then i tried to set the animations in movie clips and they won't stop. file:///Users/GS2/Desktop/links_2.fla i tried including the fla files for reference.

I have 3 buttons layed out in my design (more to come ultimately). Once you click on any of these buttons, they will add their corresponding movie clips to the stage (button 1 will add movieclip 1 to the stage, etc). Each of these movie clips are details of a project (I'm building a portfolio). Some of these movie clips will have Loader classes in them, loading external images into them for a slideshow.My problem comes in removing any previous movie clips from the stage when a new button is clicked (eg. click button 2 - movie clip 2 shows, click button 3 - remove movie clip 2 before adding movie clip 3 to the stage). I got it to work sorta, but the biggest problem comes with movie clips that have these Loader classes/images in them. When you click back to that project, you still see the last image loaded in that movie clip (like it was not cleared or reset when removed from the stage). How do I remove movie clips and all of their loaded children dynamically, while controlling them with buttons. Here is my sample code (the "showclip" function is where I need to fix my logic).
//Add the Nav Buttons to the stage
var btns_mc:MC_Btns = new MC_Btns();
btns_mc.x = 0;

Here's what I'm trying to do (in example form): I have a movie clip called "dude". Dude is animated to walk around, then drop a cigar (all inside the movie clip). But the problem is, dude moves, so if you try and move dude as the cigar is dropping, the cigar moves with him. So what I want to do is create a new movie clip instance called "cigar" OUTSIDE of the movie clip dude right as he's dropping it, so that you can move him without moving the cigar. Get it? I've attached another helpful animation to explain.
What I have right now is, on the 13th frame of dude, a few lines of code that create and place an instance of cigar. In that frame I also have an invisible instance of cigar for me to duplicate. Inside of the cigar movie clip is the animation that makes it fall to the ground. I need to change that code so that the instance of cigar is created outside of the movie clip dude. Here's the code I have now (inside of dude, on frame 13):

I've hired a freelancer, to make a design for my flash app. And everything was fine, untill I saw this. It was an animated background. It has about 100 tweened movie clips, that do pretty much the same - simple rotation tween, but cpu usage on that background only reaches 17-20%. Its high for such a small effect. I've tried to optimize it - removing all code, and leving just timeline based tween, but that didn't solve my issue.[URL]

I've built a carousel that moves a set amount with button presses, and when the movement stops the item at the front of the carousel enlarges and becomes a button. However, when the carousel is moved to the next item, the previous still stays behaves like a button. Is there any way to remove the event handler from the movieclip?

I have been looking for a way to swap a movie clips when the user clicks on them.I could not find a function for swapping them, so I dynamically generate the first one, when the user clicks on it, I remove it and add another clip (hoping to repeat the same process), however, when the second one appears it not allow me to click on it - so that I can do the same again.The code is below, and I have attached the flash file for you to take a look at - I am currently working in Flash 8.
Code:
this.attachMovie("MOV_addToBasket","addToBasket_mc",this.getNextHighestDepth());
addToBasket_mc._x = 75
addToBasket_mc._y = 50[code].......

look at my attachment and you will see that it creates 10 little pieces of ammo. When u click on the background it should delete one of those movie clips. But it deletes 2 of them. the code for creating is on the first layer and the deleting is on the background button symbol(click on the background to find it if you don't know what im talking about). create code

I have a site that is fairly complex, but was using a massive amount of CPU power, even when sitting idle on a page with no animations. I went through everything with a fine toothed comb, and couldn't find the culprit.So I just started removing layers one by one, until I found the one causing the problem.
Turns out it was a layer with an animated mask. I have a large black recatangle, that I converted to a mask, and then used a shape tween on it. Once that was triggered. The CPU usage went up 65-75%. Even when the movie was stopped on a frame that that mask didn't exist on. Once it was triggered, the rest of the time you are on the site the CPU usage is through the roof. I can do to fix that. Is there some other way I should build an animated mask?

how to imitate a reflection of a movie clip in a "mirror." I don't know if I should have the initial movie clip on custom cursor or have it set to drag... but either way I don't know how to make the second clip the "reflection follow along. Obviously it would need to follow at a slightly offset pattern so that you would be able to see both clips (or majority of them) at the same time. It's for a school project that is due at 9am tomorrow so time is of the essence!!

I was just wondering how to save CPU usage by removing inactive movie clips on the timeline. An example of what I mean is, I currently have five buttons and when you click each of them an MC tweens into the middle of the screen. But by the time you click the fifth button there are 5 MC's (with animations going on inside them) on top of each other and everything becomes quite jittery.I just wanted to get rid of the ones below until someone clicks their button again...

My game is initialized by calling the newBall function below. Every 10 seconds a new ball is created to increase the difficulty by calling the same function. The function works and creates the new ball movie clip, however the previous ball object gets destroyed for some reason. I have an array called ballArr that is supposed to keep track of all of the ball movie clips. I thought that by concatenating the name of the instance with an incrementing number that it wouldn't overwrite the existing object... what am I doing wrong?
Code:
function newBall() {
var ballNum = ballArr.length + 1;
var ball = this.attachMovie("ball_mc", "i" + string(ballNum), 0, {

I am very new to Action Script 3.0.My experience has been with 2.0 creating Movie Clips and using the timeline. My concern is after several days of trying to understand why my button was appearing as a null object.
My main timeline has 20 frames. There is a stop action on Frame 14.On frame 14 is where I've a button to advance the viewer to frame 15. This is where my trouble starts. After advancing the viewer 1 frame to frame 15, there are 3 buttons.
1)First question is in order for my buttons to work - they must be on the main timeline and not nested in a Movie Clip (correct)? 2)Second question is because I am trying to implement good Action Script practices, I've put all m y code on one frame.(Frame 14)
Unfortunately, this is where I kept getting an error about "Null Object". My 'problem-' button comes 1 frame after the Action Script.The work around for me was to insert a keyframe with the problem button and move the button off the stage.
I would like to try and get in the habit of using AS 3.0 to call Flash Objects to the stage, but it just doesn't seem to be working. Are the methods of using "Package", import Flash -"Movie Clip" or "Sprite" the preferred? Or should I just stick with my very simple way of working? I am afraid it will cause problems down the road and cause unncesassary load times becasue I've got everything on the stage - even when not needed. But, this seems to be the only way my movies work.

I wanted to post this here, in case someone more AS oriented should see it... I don't think it's getting much attention in the other thread... My problem is with creating duplicate movie clips, and then being able to access them again, to move them, or whatever.... you can see more details HERE
