I'm creating a quiz with buttons and I'm new to ActionScript 3.0, but very familiar with 2.0.
I have a variable inside of a MC called NextQuestion. When it reaches a certain frame, it changes to 1, then back to 0.
On the main timeline, when NextQuestion == 1, it's supposed to NextFrame();. I can't get it to work though, this is the last thing I'm having trouble with.
This is my main code with 4 buttons, 3 wrong, 1 right. The feedback MC plays an animation, and when it finishes, it sets the VAR NextQuestion to 1, which is supposed to make the main timeline advance to the NextFrame.
stop();
right.addEventListener(MouseEvent.CLICK, rightClick1);
wrong1.addEventListener(MouseEvent.CLICK, wrongClick1);
wrong2.addEventListener(MouseEvent.CLICK, wrongClick1);
wrong3.addEventListener(MouseEvent.CLICK, wrongClick1);
feedback1.addEventListener(Event.ENTER_FRAME, answerRight1);
function answerRight1()
{
if (feedback1.NextQuestion == 1)
{
trace(feedback1.NextQuestion);
nextFrame();
}
else
{
trace("do nothing");
}
}
function rightClick1(ev:MouseEvent):void
{
trace(feedback1.NextQuestion);
feedback1.gotoAndPlay("right1");
}
function wrongClick1(ev:MouseEvent):void
{
trace("wrong");
feedback1.gotoAndPlay("wrong");
}
Any help is greatly appreciated! :)
The nextFrame() method in AS3 doesn't loop trough your movieClips, it just set's the movie clip to the next frame provided there is a next frame, otherwise it does nothing.
you might want to re-write the nextFrame() to:
if (totalFrames == currentFrame)
{
gotoAndStop(1); // or gotoAndPlay(1) if you need
}
else
{
nextFrame();
}
Thats regarding why the movie clip might not start from the beginning.
Another thing that look weird is that you need a FRAME_ENTER event to check if the answer is correct. You must have a lot of spam in the output log. I'd recommend you to totally ditch the ENTER_FRAME event listener for this and do it all with the CLICKED event and dispatching the event from the feedback1 object.
As much as I understand the movie clip plays when you click a button and when the animation is over you want to either progress to next frame or do nothing. If so, on the feedback1 object add a following line in the end of animation for label "right1":
dispatchEvent(new Event("right"));
and instead of the line feedback1.addEventListener(Event.ENTER_FRAME, answerRight1); have:
feedback1.addEventListener("right", answerRight1);
That way you won't need to check the answer on every frame and you don't need to check if the answer is right or not, because when the dispatchEvent(new Event("right")); fires - it's always right.
Hope I didn't misunderstand your question :)

Sorry this is so specific but I have combed through so many pages and videos and tutorials and can't figure this out.
I have all of my animations within a MovieClip. In the movie clip is also a stage sized white square button with the instance name "btn". Back on the main stage I have a second layer called "actions" with the following code applied to the first (and only) frame. It's not working. At all. (HUGE) tia
stop(); // this will stop the movie from playing at the start
btn.addEventListener((MouseEvent.ROLL_OVER, playMovie);
btn.addEventListener((MouseEvent.ROLL_OUT, stopMovie);
function playMovie(evt:MouseEvent):void {
play();
}
function stopMovie(evt:MouseEvent):void {
stop();
}
The problem is when you say play(); or stop(); which object are you really commanding? Your playMovie function could be in theory used to control many MovieClips at once, in different ways, so be specific with your commands...
btn.play(); //start the playback of "btn" MC
btn.stop(); //stop the playback of "btn" MC
Also consider using MOUSE_OVER/OUT instead ROLL_OVER/OUT etc but whatever works for you.
For reversing you will use btn.prevFrame(); together with an ENTER_FRAME event function. This function reads your Document settings for the FPS. For example, if you set 30 frames-per-sec then whatever instructions you put inside the event function will be processed 30 times per second.
See this other Answer for advice about reversing the playback of a MovieClip.
#VC.One is correct in how you should implement a solve to your issue, however in response to your comment on their answer, I thought I would demonstrate how to implement this fully for you - incase they don't.
var removeUpdate = false;
btn.addEventListener(MouseEvent.MOUSE_OVER, playMovie);
btn.addEventListener(MouseEvent.MOUSE_OUT, stopMovie);
function playMovie(evt:MouseEvent):void {
// Stop rewinding the movie clip and play it
if(removeUpdate){
stage.removeEventListener(Event.ENTER_FRAME, update);
removeUpdate = false;
}
// play our button
btn.play();
}
function stopMovie(evt:MouseEvent):void {
// stop our button
btn.stop();
// ... and rewind it
stage.addEventListener(Event.ENTER_FRAME, update);
removeUpdate = true;
}
function update(evt: Event){
// moves the button movie clip backwards one frame.
btn.prevFrame();
// If we have finished rewinding the movie clip, then stop
if(btn.currentFrame == 1){
stage.removeEventListener(Event.ENTER_FRAME, update);
removeUpdate = false;
}
}
It is important that you remove the update event because if you don't, the movie will never play again, because it will go one frame forward and then back again every frame due to; btn.play(); btn.prevFrame();
So I am currently attempting to remove an element from the array 'zombie_horde' as well as remove the child from the stage. My aimed result, a movie clip that is part of an array israndomly played and when finished playing, the frame changes to a gameover frame.
This is my code:
part of the big loop:
for each (var zom:Betherino in zombie_horde)
{
var frame = zom.currentFrame
trace(frame)
if(frame == zom.lastframe)
{
updatearray()
}
else{
zom.gotoAndStop(frame+1)
}
functions:
function updatearray()
{
zombie_horde.splice();
trace('spliced')
}
function removeBetherino()
{
stage.removeChild(Betherino)
}
This is what I have so far. I am wondering how I am supposed to continue to tackle this situation of removing the movie clip (AS Linkage 'Betherino') from not only the array but also the stage
Sorry I am still new to stack Overflow :(
I havent gotten up to the change frame part any suggestions on ideas would be great!
To "Remove the element from the array and the stage then go to a gameover frame", there's three steps:
Remove the element from the array
Remove the element from stage
Jump to a game over frame.
The last one, I think that's best left to you. There's no code related to gameover frames in your question, so I can't help you there.
The other elements, however...
for each (var zom:Betherino in zombie_horde){
var frame = zom.currentFrame
trace(frame)
if(frame == zom.lastframe)
{
updatearray()
}
else{
zom.gotoAndStop(frame+1)
}
}
You go through each zombie in the zombie horde, and if it's at its last frame, you try to remove it.
This implies that these zombies simply play through an animation and then disappear. Sounds strange to me. Is that really want you want the code to do?
Next... you use updatearray to remove the zombies from the array. But you do so via zombie_horde.splice(). That doesn't work. If you look at the documentation for splice then you'll see that it takes 2+ arguments: startIndex:int, deleteCount:uint, ... values. That is, the first argument is the start index to start deleting at, the second argument specifies how many you want to delete, and any arguments after that are added back in the list.
zombie_horde.splice(zombie_horde.indexOf(zom), 1);
will do what you're looking for, when inlined.
As for removing the element from stage, you need to pass an object. stage.removeChild(Betherino) is not the correct way, inline and use stage.removeChild(zom) instead. That makes for this function:
for each (var zom:Betherino in zombie_horde){
var frame = zom.currentFrame
trace(frame)
if(frame == zom.lastframe)
{
zombie_horde.splice(zombie_horde.indexOf(zom), 1);
stage.removeChild(zom);
//go to gameover frame and exit for loop
}
else{
zom.gotoAndStop(frame+1)
}
}
The "go to gameover frame" comment still needs to be replaced with the relevant code.
I don't know why I can't figure out this problem that is really basics !! (sometimes the brain is tired I guess).
I've got a movieclip with a guitar string.
I want the string to move everytime I click on it.
I've created a movie clip with 2 lables. the first = non movement, the second = movement.
I've placed in the second one a stop(); action. (in order to stop the loop)
I've put this code :
stringOne.addEventListener(MouseEvent.CLICK, accord1, false, 0, true);
public function accord1(e:MouseEvent):void{
var stringOne;
trace("DING");
stringOne.gotoAndStop("first");
}
It works but, of course, it only play the string movement at the first click.
Do you know how I could play the string movement EVERYTIME that I click on the string ?
Thank you very much and sorry for this easy question (little ashamed)..,
EDIT
Ah ! It seems to work with goToAndPlay !
if (stringOne.currentLabel=="premier") {
stringOne.gotoAndStop("default");
} else {
stringOne.gotoAndStop("first");
}
Just a thing, I have to click twice..
(one click = the string vibrate (label2))
(one click again = the string does nothing (going to label 1))
(one click again = the string vibrate (label 2))
Is there anyway to automatically skip the 2nd click (the one that tells the string to go back at label 1), and let do the code like : - When animation of label 2 is finished, automatically go back to label 1 ? –
Presumably, the "movement" label of the string is some sort of animation?
It seems to me what you want in your "guitar string" movieClip is, on the last frame of the timeline animation for "movement", a script that says gotoAndStop('non movement'). The click handler should gotoAndPlay('movement').
Then, when the string 'movement' animation is finished, it will reset itself, so that the next time you click it will play again.
So, your original code is fine (before the edit; but remove the "var stringOne;" since that will break the reference to stringOne). The only thing you need to add is a script in the timeline on the last frame of the movement animation ("first" label?) that says gotoAndPlay("default") (assuming default is the 'non movement' label). You may need a stop() in the timeline frame for "default".
Something like that :
stage.addEventListener( MouseEvent.CLICK, onStageClick);
protected function onStageClick(event:MouseEvent):void
{
switch( event.target )
{
case stringOne:
trace("String one stuff");
break;
case stringTwo:
trace("String 2 stuff");
break;
}
}
Or add your movieClip into a Sprite and listen click event on the Sprite and not on the MovieClips.
Thank you for the answer. I've found an other way, instead of mouse click I've used mouse down for going to frame 2 and mouse up for going to frame 1
Ok, so I'm a beginner at AS3 and Flash and I managed to put this code together for an animation. A Button called start_btn is supposed to start and stop a movieclip called main_mc. On the first click of the Button, the Movieclip is supposed to play (which it does), however on the second click, the movie stops in the middle of its animation (which I don't want). My question is, when you click the Button a second time, how can i get the Movieclip to finish playing its animation then stop on the last frame?
I thought about using if (main_mc.currentFrame == main_mc.totalFrames); {main_mc.stop(); but the Movieclip still does not stop on the last frame. The Movieclip itself also has a gotoAndPlay(2); command on the last frame so that the animation repeats before the Button is clicked a second time.
here is the code i have:
`start_btn.addEventListener(MouseEvent.CLICK, mainaniS);
function mainaniS(event:MouseEvent):void
{
main_mc.play();
start_btn.removeEventListener(MouseEvent.CLICK, mainaniS);
start_btn.addEventListener(MouseEvent.CLICK, mainaniSt);
}
function mainaniSt(event:MouseEvent):void
{
if (main_mc.currentFrame == main_mc.totalFrames);
{main_mc.stop();}
start_btn.removeEventListener(MouseEvent.CLICK, mainaniSt);
start_btn.addEventListener(MouseEvent.CLICK, mainaniS);
}`
Try main_mc.gotoAndStop(main_mc.totalFrames).
I was going to provide a quick and dirty solution, but decided instead to try and explain a few of the issues with your current implementation and attempt to refactor and explain and better one. Unfortunately I don't have access to Flash right now, so the code is untested.
You're adding and removing event listeners often, which is generally a bad idea. Instead, since you're using a single button to perform multiple functions it would make sense to track the button state in a separate variable. In this case, a boolean for whether or not the movieclip is currently playing.
var playing:Boolean;
Now we can combine the mainaniS and mainaniSt into one and perform a different action based on whether or not the movieclip is playing, and just keep the one eventlistener on the button. I've also taken the liberty of naming the method something more meaningful:
start_btn.addEventListener(MouseEvent.CLICK, onStartClick);
function onStartClick(event:MouseEvent):void
{
if(playing) {
playing = false;
}
else {
playing = true;
main_mc.play();
}
}
You may be wondering why we don't call main_mc.stop() in the first block: the reason is that you don't want to stop the movieclip as soon as you click the button, but after the movieclip has finished playing if the button has been clicked. Therefore, we just set playing to false to indicate that we want it to stop later.
Finally, we need to make sure the movieclip stops upon completion, but only if playing is false. To do this we add a listener to movieclip that is called every frame, and checks whether playing is false, and if it's on the last frame. Note that the last frame is actually totalFrames - 1: this is because the frame numbers start from zero rather than one (i.e. if totalFrames is 3, the frame numbers will be 0, 1, 2).
main_mc.addEventListener(Event.ENTER_FRAME, animate);
function animate(event:Event):void {
if(!playing && main_mc.currentFrame == main_mc.totalFrames - 1) {
main_mc.stop();
}
}
All the refactored code together:
var playing:Boolean;
start_btn.addEventListener(MouseEvent.CLICK, onStartClick);
main_mc.addEventListener(Event.ENTER_FRAME, animate);
function onStartClick(event:MouseEvent):void
{
if(playing) {
playing = false;
}
else {
playing = true;
main_mc.play();
}
}
function animate(event:Event):void {
if(!playing && main_mc.currentFrame == main_mc.totalFrames - 1) {
main_mc.stop();
}
}
It's been a while since I've had to write Actionscript that really needs to integrate with the timeline (in this case, controlling a series of frames that must happen in a certain sequence) and I am trying to figure out what to do.
In the first few frames, I have a button "next_1".
At frame 10, I need to have another button "next_2". I really really need this button to not be on frame one (I could possibly just make it invisible, but that's going to create a clickable area that I don't want).
The problem is, anything I don't put on "frame_1" renders as null in my Document class.
Is there any solution to this? I would rather not have to write my script on the timeline if possible (it seems easier in the long run to keep it in a document class)...
Items on the timeline are created on the fly, so if the playhead has not reached frame 10, next_2 is not created.
Easiest Document-class solution:
Create an array of frame labels like ["label1", "label2"]
Create sectionIndex var and set it to 0
Create a next button on its own layer so it is always showing.
When the next button is clicked, increment sectionIndex, then gotoAndPlay(myLabels[sectionIndex])
Okay, directly lifted from "Real World Flash Game Development":
/**************************************************
* FRAME LABELS *
**************************************************/
private function enumerateFrameLabels():void {
for each (var label:FrameLabel in currentLabels) {
addFrameScript(label.frame-1, dispatchFrameEvent);
}
}
private function dispatchFrameEvent():void {
dispatchEvent(new Event(currentLabel, true));
}
This dispatches an event at each frame label on the timeline.
Then you can just add event listeners for each frame:
addEventListener("name_of_my_framelabel", frameHandler);
addEventListener("another_framelabel", frameHandler);
And write a switch statement to add event listeners for the buttons when they actually show up on the timeline.
private function frameHandler(e:Event):void {
switch(e.type) {
case 'screen_2':
stop();
next_2.addEventListener(MouseEvent.CLICK, click2, false, 0, true)
break;
}
}
