Flash :: Animation Sequence With Triggers

Animation Sequence With Triggers
I have an animation sequence that moves an mc to 4 different points points on the stage. The the idea is to have the mc pause at each point allowing for a text bubble to pop up giving the user enough time to read them. The bubble then goes away and the clip moves to the next point. (The bubbles are in place at all times with alpha set to zero).

The desired effect is to have the bubble pop up just before the mc reaches it's designated location allowing time for the bubble to fade in. The bubble's alpha property is set to zero once the mc moves on to it's new location.

Thanks / help appreciated

Button That Triggers Animation.....
ok, i've been racking my brain for 3 days trying to figure out flash 5. i have been through all the tutorials, and i still have no idea how to do what i want.

i am trying to create a button that when clicked will triger an animation that runs once.

of coarse, i'm using simple items right now, until i figure out how to do it right. for example, i just have a big ole button in the middle of the stage, that chagnes colors when moused over and clicked, and an arrow that goes from left to right.

what i want to do is to just look at the button and when i click it, the arrow goes across the screen once.

i have tried everything that i can think of, but its just not working. everytime test the movie, it shows the button, but the arrow is nonstop flying across the screen.

the closest i got was that when i push the button, it restarts the animation, but it still keeps going.

i know that i'm new, and this is probably something really simple,but i have looked all over the place and just can't find anything.

please help

[Flash8] Mouse Triggers Animation
Hello gurus, (or is it guri?)

Basically I want to have something pop-up, and stay up on when the mouse moves to a side of the swf, but it re-animates the pop-up motion when the mouse is moved even after it is on one side. Here is the script I wrote for it: (left_motion is the mc that has the animation.)

onMouseMove = function() {
if (_xmouse <= 300) {
left_motion.gotoAndPlay("up");
trace("mouse is on the left");
}
if (_xmouse >= 301) {
left_motion.gotoAndPlay("down");
trace("mouse is on the right");
}
};

So what I'm wondering is, how do I have the pop-up animation happen only when the mouse has changed from the right to the left, and vice versa (sides determined by the x position of the mouse). I know there must be a way. I appreciate your help!

Thanks,
trippel

Sequence Animation?
A basic question, for eg. I want to create a 3d ball that looks like mercury ball that rotates on water that is rippling. where would u create this. Is it done in photoshop using different plugins and then exporting each sequence to flash?

Button Animation/sequence?
OK don't know what this feature is called but i'll try to describe as much as what i want to be able to do.

I want list of dates that people can click, when these dates are click a submenu will appear, with seperate slide out boxes, but with just readable text in it.

ermm not sure if you can understand what i what from that lol but lets see how it goes

Problem In Sequence Animation
dear Friends

This is my first thread in this forum... I strucked with an animation in MX. I want to show on a web page a sequence of images sliding just like a rail boggy movement. The images will move one after another continously. after last picture, automatically first picture should come. There should be no white space after end of last image.
i am using movie clip for this, but while play back, i am finding a white gap before it starts again. How to fix this? I dont know much action scripting.Please help me.

Animation Sequence Memory Help
i have imported a sequence of PNG files into an swf, i then load the swf into my main flash file. as i view each image it starts to drain my computers memory quite dramatically.

Is there a better way of doing what im trying to do? rather than having to load each image into memory?

how do they do it on the halo site (http://www.halo3.com/believe) as this is pretty much exactly what im doing, except the halo site doesnt eat all my system memory.

Cheers

Animation Sequence Problem
hi shocker,

I am working on some trasition effects between sections. You know, when user click another section, I want to have an animation to close the current section then load next section swf file and then another animation to open the next section.

I am gonna use external xml file to store all the actual content data (text / images). But the inter-section transitions are gonna actually build in the fla file.

To give you a clearer idea, the trasition I am trying to is something like this:

current section close animation (in order):
- regular timeline animation in mc
- fuse animation sequence (2 clips, one follows another)
- reguarl timeline animation in mc
...

- load the next section swf file

next section open animation is simply a reverse the close animation sequence, but just bring in the loaded swf file with external xml data at the end of the open animation.

well, I hope that I have made myself clear enough. My question is, what is the usual strategy to achieve this? Especially here, I use a combination of traditional regular timeline mc animation and an as fuse animation. (I mean if I purely only use fuse, it's gonna be easy to make a sequence 'cause that's basically what fuse does). Now I got totally confused with my code where contains too much "if" statement and "onEnterFrames".

I know this isn't something that can't be easily made clear in a few words, but maybe just give me some ideas to light up my way .

thanks again.

Importing Animation Frames Into A Sequence
I am pulling in an animation of roughly 300 frames and rather than me importing the frames to the library and then pulling them onto the stage one at a time is there an easier way to grab a sequence of images and say "put on stage each in it's own frame"?

I swear there used to be.

Buttons Connected To Animation Sequence
I've been really racking my brain trying to figure this out.
Does anyone know of a tutorial or script that connects buttons to an animation sequence as done on http://sksantos.com. It looks like the movies and button movements are done with SetInterval, but I can't figure out how to restart the animation sequence from a button once it is press.

Any clues will be greatly appreciated.

Actionscrip V2 Animation Sequence Problem
Hello All,

This is the problem I am facing. I am doing a 3d site in which I have to manipulate a lot of the animation via actionscript, a sneak peak can be found http://existanze.com/luminous/ (Version 4). I am moving into the next step wich is to animate the different objects on the site.

I need to be able to work in sequences, in simple terms, when one animation finishes another begins. This sounds simple, but its not if you are animating using loops and so on. If I was using tweening I could easility add a keyframe that would trigger the next part of the animation.

An example would be more appropiate. If I have three functions, turnLightsOff(), fallDown(), grow().

turnLightsOff() gradually decreases the alpha
fallDown() gradually decreses the _y position by 10
grow() gradually scales an mc.

When I put one method after the other, they start in the correct order, but they all get carried out at the same time. How can I restrict fallDown() from being carried out until turnLighsOff() has finished execution?? And add delays between each animation.

Please remember that each method is executed between different mc's not on the same one.

Thank in advance for any replies.

How To Stop Animation Sequence At A Frame Number?
Hi all

I've just recently started learning Flash (I have CS4) and I have a small simple animated sequence at the start which then leads to the main home page.
now the animation part works fine but when I test it it just runs right through - it doesn't stop at my main page which then the viewer will click a button to go to a different part of the site etc.
I've tried adding a stop actionscript but I'm sure I'm not doing it right! how do I refer the stop to the animation... do I have to enter the frame number I want it stopped at etc?

if anyone can make any suggestions or point me in the direction of a tutorial (or the correct wording for me to do a search myself) then I would be very grateful!

Thank you for your time :-)

? How Do I Create A Hover-triggered Animation Sequence ?
i'm designing a page and here's what i'd like to do. i'd like to have one image in the middle of the page, upon hovering or clicking, i'd like to trigger an animation sequence where three images appear ABOVE the original image, and i'd like them all to be links. help? thanks a million!

Flash Left/Right Drag Animation Sequence
Hi. I haven't used Flash in a long long time (Flash 3.) I'm trying this on the latest version of Flash. I've got an animation sequence - Jpgs. or bmps - or I can convert to a movie.

The image sequence is a rotating 3d image that goes counterclockwise.

I'd like to take this sequence into Flash and be able to drag left to make it appear that you are rotating the object clockwise and vice-versa.

Any suggestions/help is greatly appreciated.

Graphic Based Animation Sequence Using Insane Amounts Of Ram?
I am trying to imitate 3d rotation of a piece of equipment in flash CS3. Currently we are creating the 3d models in 3d Max and exporting animation sequences in the form of 120 PNG files per complete rotation of each piece of equipment. The total size of the graphics for one sequence is currently around 8mb or smaller. Each graphic gets put on its own frame in a movieclip and then that clip is played when the user presses the control to rotate that piece of equipment. When the sequence is played flash is using an insane amount of ram though. When the application is launched it uses less then 20mb of ram. After one single animation sequence 8mb in graphic size is played the ram usage balloons to 200-250mb. I donâ€™t understand why displaying a sequence of graphics totaling 8mb in size is using 200+mb of ram. The problem is greatly compounded with the fact that we need multiple pieces of equipment with multiple animation sequences depending on the state of the equipment at the time the rotation is requested. This is the demo/test piece for multiple large training simulations that might contain 200mb worth of graphics so if 10mb is turning into 250mb ram usage we have serious problemsâ€¦

Is there a problem with CS3 using more ram then it should or are we just doing something wrong? I canâ€™t believe flash needs 250mb of ram just to display a sequence of graphics totaling less then 10mb.

Preloader Running Whilst Animation Carrying Out Sequence
:-

Having a few problems getting a preloader to run alongside an animation...the movie itself is based around two key frames because developing with scenes caused it to stop, in Flash MX. I have an animation where a door opens and the main site is seen through it, but the preloader seems to stop the tween?

Any ideas what I might be doing wrong?

Thanks!

Triggers/buttons
Hey guys

Was wondering if there was a way I could have a button that was active but when u hover over it you dont dont get the active button cursor, it just stays the same.
An example of what i want is here:

Things are triggered by hovering over objects but the cursor stays the same.

Any ideas?

Movieclips As Triggers
OK I try my best to explain this. I have this movieclip (instance name "t1") i use as a trigger when a car (i_car) hits it. Inside it there is 2 frames. The idea is to get the car going under the bridge when trigged and normally the state is that the car goes above the bridge.

Frame 1:
if (_root.t2.hitTest(_root.i_car)) {
_root.i_bridge.swapDepths(200);
_root.t2._yscale = 300;
_root.track.i_collision.gotoAndStop(3);
} else {
_root.i_car.swapDepths(200);
_root.t2._yscale = 100;
_root.track.i_collision.gotoAndStop(2);
}
Frame 2:
gotoAndPlay(1);

I use this trigger at the end of the bridge. (the road going under it). Problem is when ever i put another similiar trigger movieclip, this new trigger doesn't work. I just can't find the reason why it wont work.
This first trigger works fine.

Time Laps Triggers
Is there a way to trigger a Target/movieclip based on the user takin too much time?

example: 30 seconds without the user choosing anything
a warning shows up or a demo would play similar to a video game??

Thanks

Mouse-over Re-triggers Movie
Hello,
i have a pop-out menu and i'm trying to figure out how to keep a movie (within my main movie) from re-starting when someone mouses-over a new button.

Here's the actual menu - http://www.layaboutband.com

if you mouse over it, it opens, but if your mouse stays stationary, it starts to close. the reason, as i see it, is that the menu names (music, photos, etc) are the buttons, and the brown background is not.

basically, i want it to open and stay open as long as the mouse is there, and the whole thing close when you mouse-off of the menu.

maybe i dont have this setup right, i'm new to it all.

attached is the FLA, and here's a zipped up copy of the FLA if that helps:

thanks a lot for any help

[F8]end Of Sound Triggers Url Launch?
I have an animation set to 40fps but as you will know some computers wont reach that.

The problem is on my computer it does and I have a music file being played on the intro. On here I have it set so that when the animation stops it will forward to an address but on old computers it will play the audio but have a big gap until the animation has finished.

Is there anyway with actionscript to find out when the loaded audio has finished playing and then go to a URL?

I'm sure there is but I just don't know it.

Also I have a button that I need to fade after 10 seconds. Is there anyway that I can constantly update a variable of the current progress of the audio file so that when the audio file reaches 10 seconds it will fade the button?

Thanks to anyone who can help me with this

[F8] Cordinate Triggers Event
In AS2 , I have a MC that moves across the stage. When it reaches a certain cordinates I need it to load an external swf . I usually load externals swfs via button event but now I need it to load when it reaches a certain position on the stage . Any help would be cool ....Thanks

Key Press Triggers On(release)
This is a strange one. I have a mouse listener and a key listener. The mouse listener listens for mouseDown and mouseUp and the key listener listens for keyDown and keyUp.

The problem is, if a user clicks the mouse (so mouse is currently down) and then presses a key the mouseUp function fires.

The same thing happens if you put the code on a movieclip and use on(press) etc for the mouse and onClipEvent(keyDown) etc for the keyboard.

Anyone had this before and know how to resolve it?

FLASH BUTTON Triggers URL

Buttons As Clip Triggers
Ok...i' am yet to find an elegant solution to this problem, i wonder if anybody knows...

let's say that i have 3 buttons in a menu and 3 clips(i say 3 to explain the scenario, i want it to work with n buttons and n clips).

each clip has a timeline-based animation going from frame 1 to frame 20.

if i click on button one i want clip one to start the animation and stop at frame 20.

then if i click on clip 2 i want first clip 1 to play the animation reversed (20 ->1) and only AFTER to play clip2 from frame 1 to 20.

now if i click on button 3 i want clip 2 o play the animation reversed (20 ->1) and only AFTER to play clip3 from frame 1 to 20.

of course this has to happen with any button clicked in any order: if there is a clip with the animation at frame 20 then play it in reverse and then start the related clip animation.

I managed to do it with 2 buttons and clips but already adding the 3rd one gets tricky...i am struggling to write the code properly...i'm sure i am just overlooking something..

cheers for advice...

Timer Triggers Event
Yes, I have posted this topic but its really urgent that I find a solution.

When the countdown timer reaches :30 i need a warning to display and/or sound.

ADDthis line of code:

Quote:

if (outputSec == 30) { warning.text="Warning" }

the code is below

Code:
function countDown() {
if (Math.round(outputMin)==0 && Math.round(outputSec)==0 || chk==1){
clearInterval(timer);
}else {
if (outputSec != "00") {
outputSec = Math.round(outputSec) - 1;
//trace(output);
}else {
outputSec = 59;
outputMin = Math.round(outputMin) -1;
}
if (outputSec <= 9 && outputSec > 0) {
outputSec ="0" + outputSec;

}else if (outputSec == 0) {
outputSec = "00";
}
}
}

chk=0;
stop();

Hover Triggers Movie
Hi all,

I would like to create a menu where when a link is hovered over a movie, in another section of the menu, will play a short clip (loop).

Thanks

Where To Begin With Button Triggers
I have a navigation interface designed in flash, and would like to have the buttons and other interface elements move and change and transition into the next page on click. I understand all the principle in getting a movie made and such, but how do I make my once static page move? Do I make another swf? Scene?

I really only need a push or a general idea. I think once I know the direction to think I'll be able to do it.

Button Triggers Loop?
Code:
on (press) {
x = events._x;
for (p=0; p<(math.abs(x+300)); p++) {
if (x<300) {
setProperty("events", _x, x+10);
} else if (x>300) {
setProperty("events", _x, x-10);
} else {
setProperty("events", _x, x);
}
}
}
It's supposed to loop enough times to move the MC to the specified position from where it was. Right if it is left of there and vice versa

[F8] Countdown Timer Triggers And Event...possible?
Hi,

I have a timer counting down.

When it hits :30 I need a warning sound and message.

Not sure how to do this. I thought some kind of listener

Below is the code

Thanks

Code:
function countDown() {
if (Math.round(outputMin)==0 && Math.round(outputSec)==0 || chk==1){
clearInterval(timer);
}else {
if (outputSec != "00") {
outputSec = Math.round(outputSec) - 1;
//trace(output);
}else {
outputSec = 59;
outputMin = Math.round(outputMin) -1;
}
if (outputSec <= 9 && outputSec > 0) {
outputSec ="0" + outputSec;

}else if (outputSec == 0) {
outputSec = "00";
gotoAndPlay(3);
}
}
}

chk=0;

GetURL Triggers Popup Blocker?
Why are user initiated actions triggering popup blockers?!

Code:
my_button.onRelease = function(): Void {
getURL("http://www.macromedia.com", "_blank", "POST");
}
should not trigger a popup blocker!

Anybody know of any workarounds? What I really need to be able to use is:

Code:
my_button.onRelease = function(): Void {
LoadVars.send("https://www.paypal.com/cgi-bin/webscr", "_blank", "POST");
}
but getting the GetURL to work is a start... I've tried changing "_blank" to a named window and "_self", neither work. I've also tried using an onMouseEvent listener to open the new window and that triggers the popup blocker too.

Thanks.

BUG: Pressing A Key Triggers Onrelease - Is There A Workaround?
Hi,

This is a very annoying bug in ActionScript, which seems not to be very much known.

Consider the following trivial code:

Code:
s.onPress=function(){
trace("onPress");
}
s.onRelease=function(){
trace("onRelease");
}
where "s" is a movie clip.
If you press the mouse button on s and do not release it, so as to trigger the onPress, then, when you press any key, the onRelease is triggered!!

That is, pressing a key (even without having any listener for it at all) triggers the onRelease of a clip which had been "onPressed" if the mouse button hasn't been released yet.

Now my question is: does anyone know some workaround?

I need to drag movieclips, and I need to do things when a key is pressed WHILE dragging a movieclip. So I use startDrag inside the movieclips' onPress, and stopDrag inside the movieclips onRelease; but my problem is that when I press a key while dragging a movieclip, its onRelease will be triggered (without reason) so it will stop dragging (and run all the onRelease stuff)....

Note that the use of startdrag and stopdrag is an example of what I am doing, but is not necessary to reproduce the bug.

Thanks in advance
Matteo

Countdown Timer Triggers And Event...possible?

Cue Point Triggers Early When Buffering FLV
Hi everyone,

I'm doing a full flash video site, and have got all the video edited etc, but am at the stage where I am implementing it all into Flash and have run into a pretty big problem at the early stage of this part.

I'm using the netStream class for video playback, (although I've also tried it with the FLVPlayback component with the same problem), and if I use "ns.setBufferTime(10);", the cue point I have in the video hits way too early.
You can see what I mean here:

http://www.flash.uk.net/qualitytesti..._Holder-3.html

The cue point is set to trigger the contact details window just as she points to the right, but with the buffer set to 10 secs, it triggers at the start of the video.

Can anyone help me understand why this is happening and what I can do about it? I've been up for 2 long days trying to find an answer but haven't ben able to yet.

Another thing, is that I'd like the site to load the individual FLV's in the sequence that I choose, so the most important clips would load first. How could I tell Flash which video's I want loaded in a particular order - would that involve an array? If so, can anyone give me some advice as to the code to load a sequence of FLV's sequentially?

Thanks a lot in advance,
Olly.

Flash Button That Triggers Dynamic Url
I am not an advanced html coder but I think this should be feasible...

I am setting up a php page that creates dynamic url links within the html code. The links aren't always the same. I want to have my FLASH content contain buttons that trigger the browser to go to the specified url that are dynamically created. How do I go about this?

Is there a way FLASH can have the a button, that when is clicked, triggers a variable that I have referenced to a dynamic url and goes there?

I look forward to your help.

Drag And Drop Triggers New Scene
I'm looking for a tutorial that will help me create a flash movie that allows the user to drag one movie symbol onto another that will trigger the movie to start a new scene. There will be 4 choices for the user hence I need to set up some action script that will decipher the difference between the 4 choices and send the movie to three alternate scenes depending upon the symbol that has been dropped on.

If someone could point me to a tutorial on this (I can't seem to find what I need at Flashkit), or if you know what action script I need I will be your new best bud!

Thanks in advance,

Losing Focus Triggers GotoandPlay?
Hi Guys,

I have an input text field (not a component) inside of a movieclip. I was wondering if there was a way where when the text field loses focus (ie. when I click outside of a field, not when I tab or click into another field) if I could trigger a gotoandplay function in the movieclip. I have tried several methods and have been close, but unsuccessful. Thanks for your help!

Movieclip Event That Triggers When Size Changes

Thanks!

One Movie Clip Ends, Triggers The Next One Begins HOW IS IT DONE?

Actionscript Calculation Triggers Timeline Change
Can someone help me code a basic division calculation?

Basically:

"input text field 1"
divided by
"input text field 2"
then a button that when clicked calculates the percentage and places into a dynamic text field.

Once I get that then my next step would be to somehow make it so that percentage answer causes a movieclip to move somewhere on the timeline.

Any ideas?

Is There An Event That Triggers When A MovieClip Leaves The Stage?
Is there an event or can you create a listener for when a movie clip or other object leaves the stage?

The problem I have is with Components or classes that are used within a movie that uses the timeline. Say you have a class that appears at a frame on the timeline and the timeline is sent another frame. It is useful to have classes /components clean up after themselves. An event for this would make the job easy.
