ActionScript 3.0 :: Randomize A Movie Clip Animation?
Feb 17, 2009
I've been working on this sort of sunset-like sequence inFlash. I've created a movie clip of a star that has a sort oftwinkle animation. It consists of 3 layers. What I want to do israndomize this animation so I can use the symbol spray tool to fillmy sky with twinkling stars. If I just to a "gotoAndPlay" repeat,they all twinkle at the same time, and this looks pretty stupid. My limited knowledge and experience with Actionscript tellsme that I need to define the animation as a function and use somesort of math randomizer to control when it plays?
I press a button and have an object (a movie clip) move onto the stage - that works ok.When that movie clip gets to a certain spot, I want it to stop - that works ok.I want to be able to press the button again and have it leave the stage - that works ok.Then if I press the button again, it will come back on the stage again - that works ok.when it stops on the stage, I want a part of it to animate just once. I've been trying to do this by putting a second movie clip inside of the first, but it won't work.
I think this is possible, but I'm not sure how it would be done. I have a flash website under construction that i am building using CS4. The background was made with Poser 8, as well as most of the content. What I have is 7 flames that flicker. The flames are one MovieClip that I have placed on the stage as 7 instances. I think the flame looks great, but 7 of them all flickering exactly the same looks silly. The clip is 10 frames that loop. So...
1) could I use AS to load and play the clip starting at different frames? like instance 1 starts on frame 1, instance 2 starts at frame 5 etc, so that none flicker exactly the same?
The web-site is in html and I'm using a Flash Object layered over and image to create a circular-sonic-boom-effect when the page is loaded. Eg. The image in in a <td></td> with an absolute width of 233px and height of 310px. The flash object sits on top of the image and onLoad() invokes the flash 'clip'. The clip is a circle, expanding and fading simultaneously. It's initial position is x-100 and y-100. I'd like that the x and y positioning be random i.e on the next onLoad() the position should change to say x-134 and y-50.

Animation of the head that comes up with the crank on it is 15 frames long. The head stops at frame 15, and it begins to crank at frame 16. Do I make a keyframe at frame 16 of that still crank at its begininng position, double click it to get its own timeline, then import the other 7 images of the crank animation into this seperate timeline, animate its cycle, then go back to the main time line at frame 16 and it should play the cycle when the main timeline hits frame 16? What if I want the cycle to only crank once around and not loop? Then, what happens to this movie clip when frame 17, 18 20, 30 is playing? It takes say 2 seconds to play the crank animation so while the play head is going along after frame 16, and the crank is moving what is in its place on the main timeline after frame 16? Should I just put frames in for the length of the rest of the animation (brain and words coming out of the head)?
I am new to animating in flash and have come up against something I don't understand.I made a small 15 frame animation.I drew each of the 15 frames by hand.The animation will loop. that is if you play frames 1 to 15 and then jump back to 1 it seemlessly transitions back and can begin again.I want to convert these 15 frames into one element that I can add many times to the time line.Is there a way to do this?
I tried converting to a movieclip symbol but it only brought in one frameIf it only brings in one frame, what is the point of it being a movie clip?What is the best practice to make a self contained unit of these 15 frames so that I can reuse them?
I have a demo/spec file I'm working with (download the .fla here): [URL] I'd like to have a movie clip (FLV) start playing AFTER the animation stops playing. I know once I bring the clip in, I'll have to give it an instance name and reference it in AS, but I'm not just not sure exactly how to start. I feel like the whole timeline thing traps me up...
I have an animated item on the main stage that was imported as a swf but it needed to be edited to fit the stage. I successfully edited each frame and the whole movie is running exactly as I'd pictured it. However, I was reading somewhere that to optimize the movie, keyframes and bitmaps and graphics take up more space and that it would be better to convert an animation to a movie clip. I had to edit each frame of my swf, so right now it's in 15 different key frames When I imported them, Flash turned each frame into a bitmap and then when I edited them for size they became graphics attached to those bitmaps, each as its own keyframe.
I have three small images on the stage in frame 1. I also have an invisible button symbol over one of the images and have given this button an instance name. On frame 2 there are the same three images but with a lower opacity level and also on this frame 2 is a movie clip instance containing an animation. I need an onRollover event connected to the button on frame 1 so that when the user rolls over it, the playhead jumps to frame two and shows the images and also plays the animation in the movie clip.
I've applied the following code to the button symbol on frame 1:
and I've also put a stop action on the last frame of the animation within the movie clip in frame 1 so that it won't loop.
The problem is that when I test the movie, when you roll over the image on frame 1 it just continually loops between frames 1 and 2 - it doesn't play the animation on frame 2 as I thought it would.
Should I use Movie Clip or Graphic Symbols for Character Animation? What do people who make TV shows use. If I'm not planning on manipulating any symbols with ActionScript and I'm not using a symbol that requires it's own time line like a walk cycle, is there any reason to use movie clips symbols? If I put my animation on the web will it download noticeably faster if I use graphic symbols instead of movie clip symbols?
I created a movie clip symbol with a tween animation and created an instance of it on the main stage. The animation is in the movie clip timeline, not on the main timeline. I cannot get the mc to play using mc.play() or mc.gotoAndPlay.
For example, I've created in Flash CS a movie clip CampfireMC, which contains child movie clip:
m_fire:FireMC
FireMC is an animation of flame CampfireMC controls playback of m_fire, for example, last frame of CampfireMC uses action code:
m_fire.gotoAndStop(m_fire.totalFrames)
And the question is how to replace (not delete/add, as m_fire.gotoAndStop(m_fire.totalFrames) will not work in this case) FireMC to another animation FireMC2?
I've tried the following trick, but it doesn't work
var campfire:CampfireMC = new CampfireMC(); campfire.m_fire = new FireMC2(); campfire.gotoAndPlay(0)
how to detect if an animation in a movie clip stops?I make myself clear:I have a movie clip with different animations which I call from the stage with mc.gotoAndPlay("frame label"). Being these animation one after another in the timeline I call a stop() function to avoid the animation after to begin without being called.
Now, on the stage I want to play one of these animations and when this stops I want to make something happen.Is there an event that tells me "this movie clip is not 'animating' anymore"?
Is there a way to stop every nested mc animations as once. In other words, I would like to stop every existing playhead in my swf file with one button. Currently, I got on button stopping the main scene playhead, but it doesn't stop any nested mc animation.Here is what i got on my main scene action layer :

I have a small tween animation, which i copied to AS3 code using the automatic feature in Flash CS3. the animation basically shifts a certain movie clip horizontally (only X axis) a few pixels. the line of cose which is responsible for this is: <Keyframe index="4" x="500"/> i wanted to make this animation slightly smarter. i want to have that code take the movie clip to a specific X coordinate no matter where it is on stage at the moment the animation is triggered.
for that i wrote the following code: var n:Number = work_btn.x - (-172.4); whereas work_btn is the instance name of the movie clip controlled by the code and -172.4 is the specific X coordinate i want the movie clip to go to when the animation is triggered. i figured that way, n stores the pixel distance between the current location of my movie clip and its final destination. now is there any way i can tell the code to move the movie clip by n amount of pixels?
When I play my animation in the Flash working file, the animation stops at the end of the timeline, as it should. But when I test the movie, or export it to any movie format, it will play an instance of a movie clip symbol that I used within the animation. There are no extra frames in the timeline beyond what should be considered the last frame. Is there a setting or something I have overlooked that might cause that instance of the symbol to play at the end of the animation, without appearing in the main timeline?
I added a button symbol to a movie clip in a Flash 8 project, and the button works. OnPress it redirects to a web site.However, the animation in the movie clip becomes diabled. I get the same effect regardless of where the button is placed, e.g. scene1 timeline, movie clip, etc.
I have 4 flyout buttons on my flash and when you RollOut of the button, it plays the closing animation. But if you quickly move the mouse back onto the button before it is finished playing the RollOut, then it gets stuck and flashes and kind of strobes.
I'm trying to simulate the coriolis effect and have managed to create a drawing application that lets the user draw on a rotating movie clip. However, I would like to now create an animation that automatically draws a line onto the movie clip which ends up being curved, but I can't figure out how to convert the x, y coordinates of the pixels on the stage to the corresponding x, y values of the movie clip. Here's what I have so far:
i'm very new at flash and finally ended all the work i wanted to do here. now i just need to had the actions so it will run properly. basically i just need it to stop in each frame and run the animation of the movie clip on that frame. if it's i can put the project here so you can see what and were i need to had the actions.
I have a MC called Robot. It is animated with keyframes so that my robot appears to walk. There is an Action on frame 8 that says, "gotoAndPlay(1)".When the user pushes the arrow keys, I want to MC to move in the direction of the press arrow. I also want the MC to start playing at keyframe 9 so it plays the walking animation.
This all works but with one small problem. If the arrow key is held down, the "gotoAndPlay(9)" stops the animation from playing, instead showing only the graphic that is on the 9nth keyframe.
Code: // initialize arrow variables var leftArrow:Boolean = false; var rightArrow:Boolean = false;[code]....
Is there a way to call a function once and play the MC frames until the arrow key is not pressed? I think the problem I am having is that if the key is held down, the EventListener keeps running and starting the MC in the same frame instead of allowing the MC to play as I want it to.
